NovUSD ↔ KHR converter
Cambodia's property market is denominated in US dollars: prices, payments and most costs are quoted in USD. The Cambodian riel (KHR) is more common in local taxes, fees and everyday spending. This converter helps you quickly estimate amounts at the National Bank of Cambodia's official reference rate.
Reference rate: 1 USD = 4,027 KHR · NBC official reference as of 1 July 2026.
Read the quote direction and unit before calculating
USD/KHR states how many riel correspond to one US dollar. Multiply a dollar amount by the rate to estimate riel and divide a riel amount by the same rate to estimate dollars. Reversing the field labels does not reverse the mathematics: the inverse rate is the reciprocal of the original quote.
The National Bank of Cambodia table also contains a Unit field. Some currencies are quoted per 1 unit and others per 100 or 1,000 units. Divide the published figure by the stated unit before converting; otherwise the result can be wrong by a factor of 100 or 1,000.
Why the market is in dollars
Cambodia's economy is largely dollarised: property transactions, developer prices, income programmes and buy-backs are usually stated in USD. For a foreign investor this reduces currency risk versus the local currency, but does not remove the risk of your own currency (for example the rouble) against the dollar when moving money in and out.
Model the direct route from your base currency to the SPA currency
Where the purchase price and instalments are stated in US dollars, the buyer needs the executable rate from their own base currency into dollars. A route through riel is useful as a reference but does not describe the bank debit where the bank sells the buyer US dollars directly.
Split the budget into USD obligations under the SPA and confirmed obligations payable in KHR. Apply the route actually used by the bank, authority or payee to each group rather than one notional cross-rate to the whole transaction.
Where the riel matters
KHR is typically used for government fees and taxes (for example, immovable-property tax is calculated in riel from the assessed value), for some utilities and everyday payments, and for small cash amounts. Confirm your actual obligations and exact figures from the documents of the specific deal; rates, exemptions and thresholds can change.
Use the exchange rate required for the tax date
Cambodia's General Department of Taxation publishes a daily official USD/KHR rate supplied by the National Bank of Cambodia. For a tax or government fee, use the rate and date required by the current rule and the documents for that payment, not the latest calculator value or whichever day produces the lowest result.
Record the obligation date, calculation date, payment date and source of the rate separately. Where an authority or adviser applies another period or method, the file should state the basis for doing so.
Start with the amount the seller must receive
The SPA may require an exact amount to reach the seller. Identify that amount and currency first, then ask the bank how much must be sent under the chosen allocation of payment charges.
International-payment charges may be borne by the sender, beneficiary or shared. SWIFT documentation notes that beneficiary or shared charges can result in deductions from the transferred amount. A currency conversion alone is therefore insufficient where the seller must receive the full contractual sum.
Compare the total debit, not only the displayed rate
For each bank quote, record the amount debited in the buyer's base currency and the US dollars actually credited to the recipient. The relationship between the two captures the executable route after the exchange rate, spread, sending fee and known intermediary deductions.
A fixed fee can recur with every transfer, so one payment and several instalments with the same combined face value can cost different amounts. Compare quotes for the same amount, at the same time, into the same receiving currency and with the same allocation of charges.
An instalment plan creates a series of currency events
Where the buyer earns and saves in a currency other than the US dollar, every instalment carries its own exchange-rate exposure. Record the amount and date of each obligation, dollars already available, the balance still to be converted and the base currency expected to fund it.
Display a base case and a buyer-defined adverse exchange-rate case. Do not project today's quote across all future payments as though it were guaranteed, and do not treat expected rent as an available source of currency before it has been received.
Round only after completing the calculation
Retain adequate precision for the rate and intermediate values, especially where an inverse or cross-rate is used. Rounding every stage separately creates cumulative drift that becomes material on a property price.
Apply final rounding according to the bank, authority or invoice that governs the payment. The saved calculation should display the source rate, quotation unit, unrounded output and final amount payable.

For a material payment, retain the quote date and time, expiry, direction, unit, charges, amount sent and expected amount received. After settlement, add the bank confirmation, seller receipt and updated SPA balance.
National Bank of Cambodia rules require a licensed or authorised money changer to display daily exchange-rate quotations, while the code of conduct provides for transaction receipts. For cash exchange or local conversion, check the operator's authorisation and retain the receipt; a calculator screenshot is not a substitute.
