Money and Prices

Vietnamese prices become manageable once you stop translating through English “thousand” and read them directly in Vietnamese units: nghìn, triệu, and tỷ. The currency word đồng follows the amount and never takes an English-style plural ending. A price such as 125,000 VND is một trăm hai mươi lăm nghìn đồng.

This page covers amounts, price questions, and the grammar of buying and selling. Phone numbers, street addresses, and identification codes use numbers as labels rather than quantities; they are treated separately on Phone Numbers, Addresses, and Codes.

Building an amount in đồng

Use number + đồng. Place-value words form part of the number before the currency unit.

The last word names the currency, so there is no cái before đồng. Nghìn, triệu, and tỷ are magnitude words inside the amount. Positional forms stay active: hai mươi mốt nghìn, mười lăm nghìn, and commonly ba mươi tư nghìn. Final bốn also occurs, so ba mươi bốn nghìn has the same value rather than being a different amount.

Written prices and locale

Vietnamese-formatted prices commonly use periods to group thousands: 125.000 đồng or 125.000 ₫. International sites may display 125,000 VND. Both can represent the same whole-number amount. By contrast, a comma in Vietnamese numerical formatting normally marks a decimal, as in 1,5 triệu đồng “1.5 million đồng.”

In messages and online listings, k after a number is common (informal): 50k means năm mươi nghìn đồng. It is a written shortcut, not the safest form for formal documents. Contracts, invoices, and official notices (formal) generally use đồng, the code VND, or both.

The form ngàn for “thousand” is widespread (regional: Southern and some Central speech), so năm mươi ngàn and năm mươi nghìn name the same amount. Nghìn is the neutral form to learn for nationwide formal writing; do not mix the spellings as though they were different values.

Asking and answering about price

Two everyday questions are Cái này bao nhiêu tiền? “How much is this?” and Cái này giá bao nhiêu? “What is the price of this?” When the item is already obvious, Bao nhiêu tiền? is natural (informal).

Giá presents a listed price; hết asks or states the total after quantities are combined. Politeness particles such as dạ and ạ make a service exchange respectful, while the numerical grammar itself does not change.

For a rate per unit, place the unit after the amount or ask with một plus the unit:

Here ký “kilo” (informal everyday measure) already supplies the measurement unit. No classifier appears between the price and đồng, or between một and ký.

Currency amounts versus banknotes

Counting money as value differs from counting physical notes. Use the classifier tờ for a banknote:

Năm trăm nghìn đồng is an amount; một tờ năm trăm nghìn đồng is one physical note of that denomination. The classifier changes the interpretation from value to object.

Other currencies work with their own currency noun: hai mươi đô la Mỹ “twenty US dollars,” mười lăm euro “fifteen euros.” Vietnamese still does not add a plural ending to the currency word.

A compact map of number meanings

The same cardinal inventory supports classifiers, ordinals, decimals, money, dates, clock time, duration, and calendar cycles. Natural speech comes from adding the correct interpretive unit rather than reading a string of digits literally.

Confirming an abbreviated price

In a local shopping context, hai trăm may be understood (informal) as 200,000 đồng because the product makes 200 đồng implausible. The seller restores nghìn đồng to confirm the scale. Learners should use the full unit until the context is unmistakable; a missing magnitude can change a price by a factor of one thousand.

Common Mistakes

1. Treating đồng like an English count noun

Use a classifier only when counting physical objects, as in hai tờ tiền, not when stating monetary value.

2. Reading every final digit literally

Likewise use ba mươi tư nghìn and mười lăm nghìn. Positional variants remain part of the price.

3. Misreading punctuation through English conventions

First identify the locale; a punctuation mark is not meaningful without its formatting convention.

4. Omitting a classifier when counting products

The price takes no classifier, but the count of shirts does: hai cái áo.

5. Importing American date and clock order

Vietnamese unit words make the structure explicit: ngày precedes the day, tháng precedes the month, and rưỡi follows giờ.

Key Takeaways

• State values as number + đồng, with nghìn, triệu, and tỷ inside the number.
• Preserve mốt and lăm, and recognize common final tư: hai mươi mốt nghìn, ba mươi tư nghìn, mười lăm nghìn. Final bốn is also possible.
• Distinguish an amount from physical notes: năm trăm nghìn đồng versus một tờ năm trăm nghìn đồng.
• Restore omitted magnitude words whenever context might not make the scale safe and clear.
