“We Buy” and “We Sell” are written from the exchange service’s point of view. Once you identify which currency the service is buying or selling, the correct side of the rate board becomes much easier to use.
Quick answer: if you bring foreign cash and want VND, the service is buying your foreign currency, so the relevant side is normally We Buy. If you use VND to obtain foreign cash, the service is selling that foreign currency to you, so We Sell is normally the relevant side.
Rate-reading guide reviewed: 22 September 2026. Always pair a rate with its timestamp and current transaction conditions.
The simplest way to remember it
You give foreign cash and receive VND
You give USD/EUR/AUD/etc. → the service buys that foreign currency → use We Buy.
You give VND and receive foreign cash
You give VND → the service sells you USD/EUR/AUD/etc. → use We Sell.
How to use the published rate table
- Identify the foreign currency involved.
- Decide whether you are giving that foreign currency or receiving it.
- If you are giving the foreign cash and receiving VND, start with We Buy.
- If you are receiving the foreign cash and paying VND, start with We Sell.
- Check the rate timestamp.
- Confirm any separate fee, banknote condition or transaction-specific rule.

Formula when you bring foreign cash
Expected VND before any separate fee or adjustment = foreign-currency amount × We Buy rate.
Example using a deliberately hypothetical rate: if the USD We Buy rate were 25,000 VND for 1 USD, then:
100 USD × 25,000 VND = 2,500,000 VND.
This is only a calculation example. It is not a current quote and does not promise that a particular banknote will be accepted at that rate.
Formula when you want foreign cash
Approximate foreign-currency amount before any separate fee or adjustment = VND amount ÷ We Sell rate.
Using another hypothetical example, if the USD We Sell rate were 25,500 VND for 1 USD, then 2,550,000 VND would correspond to approximately 100 USD before any other applicable condition.
Why We Buy and We Sell are different
An exchange service normally buys a currency at one rate and sells it at another. The difference between those two prices is commonly called the spread. A spread is not automatically the same thing as a separate commission or service fee.
Read Exchange Rate Spread vs Fees for the distinction between the price difference inside the quote and a separate charge.
Compare the final VND amount, not just the headline rate
Two quotes can look similar while producing different final results because of the applicable buy/sell side, a separate fee, banknote condition or the exact transaction amount. Compare the same amount of the same currency under the same conditions.

Banknote condition can change the transaction
A published rate does not prove that every note of that currency will be processed in the same way. Old series, writing, stains, tears, tape or unusual denominations can require additional review.
Use the Banknote Guide before making a special trip with unusual cash.
Rate timestamps matter
Currency rates change. A screenshot, cached search result or travel-forum post can show an older number without making that obvious. Use the current published timestamp and confirm a larger or time-sensitive transaction before traveling.
