Converting Vietnam dong to USD is the easy part, and every result above this one does it for you. What the converters leave out is everything after the number.
The harder question is what that number means once you are holding the notes. What is a 500,000 note really worth, and why does it look so much like a 20,000? Where are you actually allowed to change money? Here is the rate from a Vietnamese bank with the timestamp attached, then the rest.
What is the Vietnam dong to USD rate today?
On 21 September 2026 at 12:28 Vietnam time, Vietcombank's published rates had it buying US dollars in cash at 25,790 VND and selling at 26,200 VND.
The buy rate is what you receive when you hand over dollars. The sell rate is what it costs to buy dollars back before you fly home. The 410 dong between them, about 1.6 percent, is the bank's margin. That margin is why your bank rate never matches a converter's mid market rate.
The daily central rate that Vietnamese banks trade around is set by the State Bank of Vietnam. Commercial banks quote their own prices around it, and every conversion below uses the 25,790 buy rate, because that is what a traveller actually transacts at.
| You hand over | You get (at 25,790) | Roughly |
|---|---|---|
| $1 | 25,790 VND | A banh mi, or a coffee at a pavement stall |
| $10 | 257,900 VND | A full day of street food for one |
| $50 | 1,289,500 VND | A night in a well rated hotel, with change |
| $100 | 2,579,000 VND | Two nights and most of your meals |
| $500 | 12,895,000 VND | About twelve nights at the median hotel rate below |
| $1,000 | 25,790,000 VND | About 24 nights at that rate, plus food |
Going the other way, when you are holding notes and want to know what you just spent:
| Vietnamese dong | In USD | What it usually covers |
|---|---|---|
| 10,000 VND | $0.39 | Iced tea, or parking a scooter |
| 50,000 VND | $1.94 | A bowl of pho at a local stall |
| 100,000 VND | $3.88 | A short Grab ride across town |
| 200,000 VND | $7.75 | Dinner for two, sitting on plastic stools |
| 500,000 VND | $19.39 | The largest note printed |
| 1,000,000 VND | $38.77 | About one night in a good mid range hotel |
| 10,000,000 VND | $387.75 | A week of comfortable travel |
What does a million dong actually buy?
A little under $39, which is close to one night in a well reviewed hotel. Guide Machine hotel data, refreshed 5 September 2026 is our own scrape of 303 Agoda listings for Da Nang, priced for mid October 2026. Agoda is an affiliate partner of this site.
- Median nightly rate: $41.73, or 1,076,000 VND
- A quarter sit at or below $27.38, or 706,000 VND
- The cheapest with real review volume: $9.13, about 235,000 VND
One million dong is a comfortable night. One hundred thousand is a meal out or a taxi. Ten thousand is small change, and you collect a lot of it.
Which Vietnamese banknotes get confused?
Vietnamese banknotes are polymer, issued by the State Bank of Vietnam. Two pairs sit close enough in colour that mistakes are routine rather than rare.
The 20,000 note is blue. The 500,000 note is also blue, slightly greener and slightly larger. It is twenty five times the value. The second pair is the 10,000 and the 200,000, both brown and yellow.
The habit that fixes it: read the zeros, never the colour.
Plenty of overcharging stories are not overcharging at all. A 500,000 note went across the counter as a 20,000, and nobody counted the change.
Where should you change money in Vietnam?
Here is the catch before the charm. Vietnamese law restricts foreign currency exchange to licensed institutions. The UK Foreign Office puts it plainly on its Vietnam safety and security page, updated 26 June 2026: "Only change money at official money exchange counters with a clear sign showing this status. Changing money elsewhere is illegal and you risk losing your money."
That matters because of what you will read elsewhere. A decade of forum posts about the black market rate points at the gold shops, the jewellery counters on Ha Trung street in Hanoi and around Ben Thanh in Saigon, on the promise of beating the bank by a shade.
Some hold licences and some do not. An unlicensed counter is unlicensed whatever the rate says. You have no recourse if the count is short, and the upside is a fraction of a percent. On $500 it is a couple of dollars.
So keep it boring:
- Use a bank branch or a licensed counter with its certificate on the wall
- Take the receipt, and count the notes before you walk away
- Bring clean, unmarked bills, because Vietnamese counters refuse torn ones
- Change a $100 bill in good condition, which usually earns a better rate than small notes
- Declare cash over 15,000,000 VND or $5,000 at the Vietnam Customs desk
What do ATMs in Vietnam actually charge?
An ATM withdrawal here is charged twice. The Vietnamese bank that owns the machine takes a fee, and your bank at home takes its own foreign withdrawal fee plus a currency margin.
Neither is guessable in advance, but only one is a mystery. The machine shows its own fee on screen before you confirm, so read it and walk on if it is steep.
Your own bank's half is already published. Look up its foreign ATM fee and transaction margin in your account fee schedule before you fly, and most of the stack is known before you land.
The third charge is the one fully in your control. Do this at every machine:
- Decline the conversion. The ATM will offer to complete the transaction in your home currency, showing a friendly dollar figure. That is dynamic currency conversion, priced by the ATM operator rather than your bank, and it is consistently worse.
- Choose to be charged in Vietnamese dong. Let your own bank do the conversion. The same prompt appears on card terminals in shops and hotels, with the same answer.
- Withdraw larger amounts, less often. The fixed fee per withdrawal is the part that hurts.
Where do cards stop working in Vietnam?
Cards work in hotels, malls, chain supermarkets and anywhere aimed at visitors. They stop working at exactly the places worth going to.
That means the pho stall with four tables, the bakery, the market, the grandmother with a charcoal grill, and most taxis. Those are cash businesses.
Grab handles the gap: attach a card in the app and pay for rides and food without touching notes. For everything else carry 300,000 to 500,000 VND in small notes. Our Vietnam guides cover the rest.

What do Vietnamese guests say about price?
Foreign reviews say a place was cheap. Vietnamese reviews say whether it was fair, which is the more useful signal. These are Vietnamese language guest reviews from the same Guide Machine hotel data, refreshed 5 September 2026, quoted in the original and translated here.
A guest at Sontra Sea Hotel on 27 July 2026 wrote Mức giá hợp lý so với vị trí và chất lượng dịch vụ. That translates as "the price is reasonable for the location and the quality of service." The room prices at $21.09, which is 544,000 VND.
The honest counterexample is more instructive. A guest at Grand Citiview Danang Hotel on 16 June 2026 rated the stay 6 out of 10. They opened with Mình đặt 2 phòng cho 2 đêm có pháo hoa giá hơn 4 triệu, or "I booked 2 rooms for 2 nights during the fireworks for over 4 million dong."
That is about $155. The hotel's normal nightly rate is $32.40 in the same Guide Machine hotel data, refreshed 5 September 2026. The guest added that a child surcharge came không báo trước, đến nơi mới báo, meaning they were only told on arrival.
Two lessons sit in that review, and both are about money rather than hotels:
- Festival weeks reprice everything. Check the local calendar before locking dates.
- Ask what is not in the quoted rate. Surcharges for children, early check in and a third person in the room are common, and often mentioned only at the counter.

Frequently Asked Questions
How much is $100 US in Vietnam?
At Vietcombank's cash buy rate of 25,790 VND per dollar on 21 September 2026, $100 gives you 2,579,000 VND. That covers two nights in a well rated mid range hotel plus most of your meals. The median Da Nang nightly rate in that 303 property Agoda sample is $41.73.
How much is 1 million dong in US dollars?
About $38.77 at the same 25,790 rate. One million dong is the benchmark worth memorising, because it is close to one night in a good hotel. You will hear it spoken as "một triệu", meaning one million.
How much is $1 US in Vietnam dong?
25,790 VND at the bank buy rate on 21 September 2026. Mid market converters show a slightly different figure, normally around 26,000. They quote the rate banks trade with each other at, rather than the rate offered over a counter.
Is $10,000 a lot of money in Vietnam?
Yes. At 25,790 that is roughly 258 million dong. Against the $41.73 median in that Da Nang sample, it covers close to eight months of accommodation. Cash over $5,000 or 15,000,000 VND must be declared to Vietnam Customs on entry and on exit.
How much is 500,000 Vietnamese dong in US dollars?
$19.39. It is also the largest note in circulation. It is the one most often confused with the 20,000 note, because both are blue, so count the zeros rather than reading the colour.
Can I use US dollars in Vietnam?
Some hotels and tour operators aimed at visitors quote and accept dollars. But the dong is legal tender and paying in dollars almost always means a poor in house rate. Change at a licensed counter, as the UK Foreign Office advises, and pay in dong.
For the rest of the trip, the national tourism board at vietnam.travel is the official starting point.
