The Real Cost of Renting an Apartment in Phnom Penh: A Tenant's Calculator

Prepared by the NovAsia Editorial Team

The figure in a rental listing is rarely the full cost of living in the apartment. A unit advertised at USD 700 can cost more than one advertised at USD 780 if the first building adds a high electricity mark-up, charges condominium fees and parking separately, requires a new internet installation and creates a more expensive daily commute.

Tenants usually compare monthly rent, the security deposit and the visible furniture. Recurring charges and one-off payments remain outside the decision. The cheaper apartment wins during the viewing but loses over the first twelve months.

A useful calculation answers three different questions:

1. How much cash is required before moving in?
2. What will an ordinary month cost?
3. What is the effective monthly cost of the first year after one-off charges and likely move-out expenses are spread across the expected occupation period?

The security deposit should remain visible but separate. If it is returned in full, it is not a housing expense. It is still unavailable for other uses and carries a deduction risk.

Separate expenses, prepayments and refundable money

Before receiving the keys, a tenant may be asked to pay:

• a security deposit;
• the first month's rent;
• rent in advance;
• a reservation payment;
• an agency fee;
• a condominium move-in charge;
• access-card fees;
• a parking deposit;
• internet installation;
• cleaning;
• furniture delivery.

Do not put every amount into a single line called “first-month cost”. Separate them by economic purpose.

A large refundable deposit can make one apartment look artificially expensive if it is treated as a final cost. Excluding it completely creates the opposite problem: the tenant may underestimate how much cash must remain unavailable until after moving out.

A reservation payment also needs its own label. It may be refundable, partly refundable, credited towards rent or forfeited after a stated event. Its treatment must follow the signed document rather than the informal word “booking”.

Three core calculations

Cash required before moving in

Upfront cash = refundable deposits + prepaid rent + non-refundable setup costs

This is a liquidity calculation. It answers whether the tenant can enter the agreement without using money needed for daily living, emergencies or the next move.

Ordinary monthly expenditure

Monthly expenditure = rent + condominium charges + utilities + internet + parking + cleaning + transport + other recurring payments

Use realistic consumption rather than the lowest possible estimate. A person working from home, a family using several air conditioners and a tenant who travels often will have different profiles.

Effective monthly cost for the first year

Effective cost = (recurring costs for the period + one-off non-refundable costs + expected move-out costs) / months actually occupied

If the tenant expects to stay for ten months, divide by ten rather than twelve. A twelve-month agreement followed by an early departure can be particularly expensive if prepaid rent or the deposit is lost.

Show the locked cash separately:

Cash tied up = deposits unavailable until the final settlement

A tenant may also model an opportunity cost:

Cost of tied-up cash = deposit × selected annual rate × months / 12

The selected rate is a scenario, not a promised return. It is reasonable to enter zero and simply display the amount that cannot be used.

Start with the rent, but adjust it correctly

Record:

• advertised rent;
• negotiated rent;
• currency;
• payment frequency;
• advance-payment requirement;
• fixed term;
• free days or months;
• stepped increases;
• likely renewal increase;
• whether any relevant tax is included.

A “free month” should be converted into an effective rent. For example:

• stated rent: USD 900;
• only eleven months are charged in a twelve-month contract.

Effective base rent = 900 × 11 / 12 = USD 825 per month

That does not make the payment structure identical to ordinary rent of USD 825. The free month may depend on paying several months or the full year in advance. Liquidity and counterparty risk therefore remain different.

Check when the concession applies. A free final month is worth less to a tenant who may leave early than a discount applied from the beginning.

If the landlord quotes rent in US dollars but accepts Cambodian riel, the agreement should identify the exchange-rate source and the date on which the conversion is made.

The security deposit and deduction risk

Record:

• the principal security deposit;
• any pet deposit;
• card, parking or utility deposits;
• who holds the money;
• the conditions for return;
• the return deadline;
• permitted deductions;
• currency;
• bank charges.

Cambodian civil-law principles distinguish ordinary wear from damage attributable to the tenant. In practice, the quality of the contract, move-in condition report, photographs, receipts and authority of the person holding the money matter greatly.

A simple risk classification can help.

Lower risk: the landlord and manager are verified, deductions are defined, the inventory is signed, the return deadline is stated and a receipt is issued.

Medium risk: deductions are broadly worded, the manager holds the money, the inventory is incomplete or no exact return deadline is given.

Higher risk: cash is taken without a receipt, the owner is unclear, full repainting is automatically required, deductions are unlimited or an agent holds the money without documented authority.

For scenario planning, a tenant may use:

Expected deposit loss = deposit × selected deduction probability

With a USD 1,500 deposit and a cautious 10% assumption, the model shows USD 150. This is not a forecast. It is a way to test how documentation risk changes the comparison. A low-risk base case can use zero, while a stress case can use a higher percentage.

The model must not become an excuse to accept a bad deposit clause. The stronger response is to improve the contract and evidence before paying.

Condominium and building charges

Clarify:

• whether the charge is included in rent;
• whether the landlord or tenant pays it;
• whether it is fixed or calculated by area;
• whether it can change during the term;
• which amenities and services are included;
• whether move-in and move-out charges apply;
• whether generator use, refuse collection or common electricity is billed separately.

The rules governing common property determine the obligations of owners within the building. The allocation between landlord and tenant should be stated in the tenancy agreement.

“Management included” may refer only to the private property manager, while the condominium service charge remains separate. Ask for exact wording, such as:

The rent includes the current condominium service charge. Any increase during the fixed term remains the landlord's responsibility.

The parties may choose another arrangement, but it should be equally clear.

For the calculator:

Annual condominium cost = monthly charge × occupied months + tenant-specific one-off building charges

Special assessments for major common-property works are normally an ownership issue and should not be transferred to a tenant through vague language such as “all building expenses”.

Electricity

Electricity may be billed:

• directly by the licensed supplier;
• through the building meter;
• through the landlord;
• at a fixed rate per kilowatt-hour;
• as a monthly flat amount;
• within a package subject to a usage cap.

Record:

• meter number;
• opening reading;
• rate per kilowatt-hour;
• party issuing the bill;
• billing period;
• fixed charges;
• deposit;
• late-payment consequences.

Cambodia's electricity sector is regulated by the Electricity Authority of Cambodia, while Electricité du Cambodge is a major supplier. A condominium's internal rate can still differ from the underlying supplier bill. Ask for the building's written tariff and, where possible, a recent primary bill showing the basis of any mark-up.

The calculation is:

Electricity cost = expected kWh consumption × actual tariff + fixed charges

Where no history is available, request previous bills and use three scenarios.

Do not copy a generic consumption figure without considering apartment size, orientation, number and condition of air conditioners, number of occupants and hours spent at home.

A lower rent can be wiped out by a weakly insulated apartment, west-facing glazing or old air-conditioning equipment.

Water

Water may be metered, charged per occupant, billed as a flat amount or included in rent.

Confirm:

• tariff and calculation basis;
• meter number;
• minimum charge;
• hot-water treatment;
• responsibility for leaks;
• whether common-area water is included;
• any deposit.

The ordinary water bill may be small compared with rent, but an unclear clause about leakage can create a much larger dispute. The contract should distinguish normal consumption from a hidden pipe defect or common-building failure.

Use previous bills or the exact fixed amount in the model. Photograph the meter and record the opening reading on the move-in report.

Internet and backup connectivity

Include:

• monthly subscription;
• installation;
• router purchase or deposit;
• minimum term;
• transfer or cancellation fee;
• mobile backup;
• occasional coworking use during outages.

For example:

• installation: USD 60;
• equipment: USD 40;
• subscription: USD 25 per month.

First-year internet cost = 60 + 40 + (25 × 12) = USD 400

Effective monthly cost = 400 / 12 = USD 33.33

An existing line may save money and time, but confirm who owns the account, whether the tenant can access the router, the actual speed in the apartment and the process for repairs.

For remote work, a cheap shared Wi-Fi network can carry a larger hidden cost through interruptions and forced coworking days.

Parking

Include:

• car or motorbike fee;
• deposit;
• card or remote control;
• guest parking;
• second vehicle;
• allocated or unallocated space;
• electric-vehicle charging;
• registration sticker.

“Free parking” has limited value if no space is available in the evening. Visit at the hours when residents normally return.

A household without a car may still need access for a driver, school transport or regular visitors. Do not add parking automatically if it will not be used, but do not assume it has no value without checking the household's routine.

Cleaning and household services

Possible costs include:

• weekly cleaning;
• a building housekeeping package;
• move-in deep cleaning;
• compulsory move-out cleaning;
• air-conditioner servicing;
• mattress or sofa cleaning;
• pest treatment.

Use:

Monthly cleaning cost = visits per month × price per visit + annual deep-cleaning cost / 12

Avoid double-counting the same service. If the building package already includes two visits per week, do not add a separate cleaner unless the actual requirement is higher.

Clarify whether air-conditioner servicing is the landlord's, tenant's or shared responsibility. A clause requiring the tenant to maintain equipment should identify the service and frequency rather than allowing arbitrary charges at move-out.

Furniture and equipment that are still missing

A “fully furnished” apartment may still require:

• a proper desk and chair;
• mattress protector;
• microwave;
• cookware;
• bedding;
• water filter;
• blackout curtains;
• child-safety equipment;
• dehumidifier;
• extra storage.

Separate purchases into:

• items the tenant will take away;
• consumables;
• items fixed to the apartment;
• items with a realistic resale value.

Do not allocate the full economic cost of a portable desk to one apartment if it will move with the tenant. The upfront cash requirement still includes the full purchase price.

Cost for the occupation period = purchase price − expected reuse or resale value

For a short stay, a higher-priced apartment with complete equipment can be cheaper than an empty or superficially furnished one.

Move-in and administrative charges

Ask the building and landlord about:

• resident registration;
• service-lift reservation;
• delivery deposit;
• access card or key;
• cleaning;
• utility activation;
• internet installation;
• contract administration;
• pet registration.

For every payment, record the recipient, amount, purpose, refundability and receipt. An undefined “administration fee” is a warning sign.

A refundable service-lift deposit belongs in the liquidity section, while a non-refundable move-in fee belongs in first-year cost.

Agency commission

In Phnom Penh, an agent may be paid by the landlord, tenant or both. A service described as free to the tenant can still affect which apartments are shown because the landlord's commission varies.

Where the tenant pays, confirm:

• amount;
• services included;
• payment date;
• refund if the tenancy fails;
• renewal fee;
• invoicing and tax treatment;
• exclusivity.

Add the fee as a one-off non-refundable cost unless the written terms provide for a refund.

The journey to work and school

Two apartments with the same rent can differ by more than USD 1,000 a year because of transport.

Record:

• mode of transport;
• average return-trip cost;
• number of journeys per week;
• school journeys;
• nanny or driver costs;
• parking;
• fuel;
• rain and peak-hour surcharges.

Monthly transport = cost of the relevant return journey × journeys per month

Example:

• Apartment A: USD 6 per return trip × 22 workdays = USD 132;
• Apartment B: USD 2 per return trip × 22 workdays = USD 44.

The annual difference is USD 1,056.

Track time separately. It does not belong in the cash total, but a predictable twenty-minute journey and an unreliable hour-long trip are not equivalent.

For a family, include school-bus fees, a private driver, extra collection trips, nanny accompaniment and emergency transport. Do not sign a tenancy solely on an agent's statement that the school bus “should” serve the address.

Pets

Possible additions include:

• higher monthly rent;
• non-refundable pet charge;
• separate deposit;
• deep cleaning;
• balcony netting;
• floor protection;
• dog walking;
• travel to a veterinary clinic.

Separate a refundable pet deposit from a real fee. Check the building rules as well as the landlord's consent; one cannot replace the other.

Utility packages and consumption caps

A serviced apartment may include electricity or water up to a specified allowance.

Overage = max(0, expected consumption − included allowance) × overage tariff

Confirm:

• the measurement unit;
• allowance period;
• overage price;
• whether air conditioning is included;
• water;
• housekeeping;
• internet;
• taxes.

A package offers predictability but can be poor value for a low-consumption tenant. Conversely, it may protect a high-consumption household from an internal electricity mark-up.

Paying rent in advance

A landlord may discount the price for three, six or twelve months in advance.

Nominal saving = normal total rent − prepaid amount

For example:

• normal rent: USD 800 per month;
• one-year advance payment: USD 8,800.

The normal annual total is USD 9,600, so the nominal saving is USD 800.

The tenant also exposes a much larger amount before receiving the service for the full period. Prepayment is sensible only after verifying the landlord and property and negotiating clear refund rights if the landlord materially breaches the agreement or the apartment cannot lawfully be occupied.

Compare the discount with the loss of liquidity and the difficulty of recovering money from an overseas owner or unauthorised manager.

Currency and banking charges

Record:

• contract currency;
• payment currency;
• exchange-rate source;
• rate date;
• transfer fee;
• requirements for physical US-dollar notes, if cash is accepted.

If income is earned in another currency, test more than one rate:

Rent in income currency = USD rent × exchange rate

This is sensitivity analysis, not an exchange-rate forecast.

A bank transfer may add sending, intermediary and receiving fees. Small monthly fees can make quarterly payment cheaper, but larger prepayments increase counterparty risk.

Taxes and invoicing

Cambodia's General Department of Taxation continues to administer tax on property rental. The precise obligation depends on the landlord's and tenant's status and the structure of the transaction.

A tenant should not accept a broad clause stating that the tenant pays “all taxes relating to the property” without advice. Confirm:

• whether the quoted price includes applicable taxes;
• whether a corporate tenant has invoicing or withholding obligations;
• whether the landlord can issue the required documentation;
• whether the accommodation is supplied as a serviced business and may carry other charges.

Add only amounts that the tenant is actually required to pay under the agreement and applicable rules. Do not add the landlord's assumed tax as a household expense merely because it exists.

Move-out costs

Estimate:

• cleaning;
• air-conditioner servicing;
• replacement of keys and cards;
• minor repairs;
• wall restoration;
• pet-related cleaning;
• internet cancellation;
• removals;
• disposal;
• final utilities;
• overlapping tenancies;
• expected deposit deductions.

A move frequently requires payment of the new deposit before the old one is returned.

Transition cash = removals + cleaning + overlapping rent + new deposit − old deposit received by that date

Even fully refundable deposits create a cash-flow problem when their timing does not match.

Compulsory repainting, cleaning or servicing should have a stated price or objective standard. An unlimited obligation to restore the apartment “to new condition” creates an unpredictable future cost.

Overlapping two apartments

A tenant may need seven to thirty days to move, clean and coordinate keys.

Overlap cost = old apartment's daily or monthly cost during overlap + new apartment's cost during the same period

Use the actual contract terms. Some landlords charge a full final month even where the tenant needs only one extra week.

An uncertain handover date can also create hotel and storage costs. Include a contingency where the move depends on a new building being completed or another tenant leaving.

Travel does not stop fixed costs

During extended absences, the tenant may still pay:

• rent;
• condominium charges;
• internet;
• parking;
• minimum cleaning;
• humidity control;
• basic electricity.

Paid months and months of actual use are different. A person absent for four months a year may find flexible serviced accommodation more economical than a low advertised rent under an inflexible annual agreement.

First year, later years and the expected stay

The first year includes installation, agency fees, purchases and move-in charges. Later years may bring a rent increase and renewal fee but no setup expenditure.

Calculate separately:

• first-year cost;
• second-year cost;
• average cost over the expected stay.

Monthly share of setup costs = non-refundable setup costs / expected months of occupation

A high setup cost may be acceptable over three years and unreasonable over six months.

Update the model if the family expects a child, a second vehicle, full-time home working or a school change. The correct apartment can change when the household routine changes.

Keep the model understandable. A precise-looking spreadsheet built on guessed inputs is less useful than a simple model with three transparent scenarios.

Worked example

The following figures are illustrative rather than market quotations.

Apartment A

• rent: USD 700;
• condominium charge: USD 70;
• electricity: USD 120;
• water: USD 10;
• internet: USD 30;
• transport: USD 140;
• one-off non-refundable costs: USD 500;
• move-out costs: USD 250;
• term: 12 months.

(700 + 70 + 120 + 10 + 30 + 140) × 12 = USD 12,840

12,840 + 500 + 250 = USD 13,590

13,590 / 12 = USD 1,132.50 per month

Apartment B

• rent: USD 800;
• condominium charge included;
• electricity: USD 90;
• water: USD 10;
• internet included;
• transport: USD 50;
• one-off non-refundable costs: USD 150;
• move-out costs: USD 200.

(800 + 90 + 10 + 50) × 12 + 150 + 200 = USD 11,750

11,750 / 12 = USD 979.17 per month

Apartment B has a listing rent USD 100 higher but is approximately USD 153 per month cheaper in this example.

The comparison does not prove that Apartment B is better. It shows why asking only about rent can produce the wrong financial conclusion.

Use three scenarios

Low case: moderate air-conditioning use, full deposit return and limited transport.

Base case: realistic utility bills, normal journeys and standard move-out costs.

High case: intensive cooling, more transport, higher internal utility charges, partial deposit deduction and one month of overlapping housing.

The preferred apartment should remain affordable in the high case. If one uncertain electricity tariff or deposit clause makes it unaffordable, the financial margin is too narrow.

Add non-financial scores

Keep a separate score for:

• noise;
• daylight and heat;
• safety;
• management quality;
• journey reliability;
• backup power;
• water reliability;
• layout;
• landlord reliability;
• probability of recovering the deposit.

A calculator helps remove misleading bargains. It should not force a tenant to choose an apartment with mould, unsafe access, a weak lift system or an unverified landlord merely because the spreadsheet total is lower.

Warning signs that later become expenses

• no written electricity tariff;
• condominium charges can change without limit;
• the landlord can add unspecified fees;
• no separate meter;
• only one internet provider is allowed and service is weak;
• parking is promised only verbally;
• repainting is compulsory regardless of condition;
• no deposit-return deadline;
• a renewal fee is hidden;
• advance rent is never refundable even after a serious landlord breach;
• previous utility arrears remain attached to the unit;
• the building's move-in fee is not disclosed;
• pet charges duplicate one another;
• the tax clause is unlimited;
• only the landlord decides the exchange rate;
• compulsory cleaning must use one contractor whose price is not stated.

Every unclear clause is an uncertain future cost.

Request a written cost schedule before signing

Ask the landlord or manager to confirm:

• monthly rent;
• everything included;
• condominium charge;
• electricity tariff and billing basis;
• water;
• internet;
• parking;
• cleaning;
• cards;
• move-in and move-out charges;
• pet charges;
• taxes payable by the tenant;
• deposits;
• return deadline;
• repair responsibilities.

Ideally, attach the schedule to the tenancy agreement. A messaging record can help as evidence, but it is weaker than a clear signed contract.

For the first three months, record actual utilities, meter readings, transport and any repairs. Compare them with the forecast. If electricity is materially higher, investigate the tariff, meter, air conditioners and apartment heat load rather than relying on assumptions.

For a short studio tenancy, the model can remain simple:

Package rent + transport + deposit risk + setup costs

For a family renting an unfurnished apartment, a fuller calculation is justified. The level of detail should match the decision.

The central rule

Compare:

Effective monthly cost + upfront liquidity requirement + suitability of the apartment

rather than the listing rent alone.

The strongest option is the one in which expenses are written down, measurable, predictable, linked to a meter or contractual rule and appropriate for the expected length of stay.

A low advertised rent has value only if it remains low after condominium charges, utilities, transport, setup and exit.

This material is for general information and does not replace legal, tax, financial or utility advice. Exact charges, tax treatment, tariffs and responsibilities should be confirmed for the specific apartment, building, landlord and tenant.

Frequently asked

Should a refundable security deposit be included in the cost of renting?

If it is returned in full, the deposit is not an expense. It still ties up cash and creates a risk of deductions, so it should be shown separately as an upfront liquidity requirement and, where useful, as the cost of frozen funds.

Which matters more: the agreed rent or the effective monthly cost?

The effective cost is more useful because it includes utilities, condominium charges, parking, internet, transport, move-in and expected move-out costs, while spreading one-off expenses over the expected period of occupation.

Can electricity charges be compared between different buildings?

Yes, but compare the meter, billing unit, basis of the tariff and any building mark-up. One building may pass through the supplier's bill, while another applies its own fixed rate per kilowatt-hour.

Who pays tax on rental income?

That depends on the landlord's status and the contract. A tenant should not automatically add the landlord's tax to the rent unless the agreement allocates it clearly. A corporate tenant may need separate tax advice on invoicing or withholding obligations.
