Vietnamese Numbers: The Ultimate Free Guide

Vietnamese numbers are one of the most basic and essential topics that every learner should know.

Fortunately, Vietnamese numbers are very logical and easy to learn.

As long as you're familiar with numbers 0-10 and a few basic number rules, you will be able to learn everything in one sitting.

So in this lesson, I won't be writing a long list of numbers!

Instead, I'll be teaching you number rules, and how you can use them for counting, talking about money, and doing simple math.

Let's get started!

Numbers 0 - 10

"Number" in Vietnamese is Số, or you can say Số đếm for "cardinal number".

First, let's look at Numbers 0 to 10.

Vietnamese Numbers 1-100

Going beyond 1-digit numbers is simple since Vietnamese numbers are made up based on basic mathematic rules. For example:

• 11 = 10 + 1 = mười một
• 19 = 10 + 9 = mười chín
• 22 = 2 x 10 + 2 = hai mươi hai
• 98 = 9 x 10 + 8 = chín mươi tám

In addition, there are only 5 other simple rules that you have to memorize.

Numbers 10, 20, 30, ...

• When numbers 2 to 9 are in the tens place, the number changes its tone from MƯỜI to MƯƠI.
• 10, 20, ..., 90 can also commonly be read as "number + chục"

Numbers 11, 21, 31, ...

• When 1 is the last digit in the numbers, except for number 11, its tone changes from MỘT to MỐT.
• In speaking, numbers 21 and above can be shortened by dropping the word mươi. For instance, 51 can be read as năm mươi mốt, or as năm mốt.

Numbers 14, 24, 34, ...

• When 4 is the last digit in the numbers, except for number 14, you can use either BỐN or TƯ to call it.

Numbers 15, 25, 35, ...

• When 5 is the last digit in the numbers, its tone changes from NĂM to LĂM.
• In Vietnamese, năm also has another meaning as "year". Therefore, 5 years would be read as "năm năm", 15 years would be "mười lăm năm"

Review Numbers Rules from 0-99

• Vietnamese numbers are made up based on basic mathematic rules
• In speaking, number 21 and above can be shortened by dropping the word mươi (e.g. 51 = năm mươi mốt = năm mốt).
• When number 2 to 9 are in the tens place, its changes tone from MƯỜI to MƯƠI.
• When 1 is the last digit in the numbers, except for number 11, its tone changes from MỘT to MỐT.
• When 4 is the last digit in the numbers, except for number 14, you can use either BỐN or TƯ to call it.
• When 5 is the last digit in the numbers, its tone changes from NĂM to LĂM.

Hundred in Vietnamese

To review, tens in Vietnamese is CHỤC. In this lesson, "hundred" in Vietnamese is TRĂM.

Here's how we say numbers: 100, 200, 300, ...

Basic mathematic rules, once again, are applied for numbers 100 and above:

• 110 = 100 + 10 = một trăm mười
• 211 = 2 x 100 + 11 = hai trăm mười một
• 515 = 5 x 100 + 15 = năm trăm mười lăm
• 999 = 9 x 100 + 99 = chín trăm chín chín

Here's how we say numbers: 101, 102, 103, ...

Number 0 in Vietnamese is KHÔNG. However, when 0 is in the Tens, it is read as LẺ.

Same rule can be apply for other numbers. For examples:

• 205 = hai trăm lẻ năm
• 507 = năm trăm lẻ bảy
• 801 = tám trăm lẻ một
• 909 = chín trăm lẻ chín

Please note that LẺ is used in the Southern dialect and LINH is used in the Northern dialect.

Thousand in Vietnamese

To review, in Vietnamese "ten" is CHỤC, and "hundred" is TRĂM. In this lesson, we'll learn "thousand" is read as NGÀN

When 0 is in the Tens, it is read as LẺ. When 0 is in the Hundreds, it is read as KHÔNG.

1,000
= 1 thousand
= một ngàn

1,001
= 1 Thousand 0 Hundred and 1
= một ngàn không trăm lẻ một

1,010
= 1 Thousand 0 Hundred 10
= một ngàn không trăm mười

1,011
= 1 Thousand 0 Hundred 11
= một ngàn không trăm mười một

1,101
= 1 Thousand 1 Hundred and 1
= một ngàn một trăm lẻ một

10,001
= 10 Thousand 0 Hundred and 1
= mười ngàn không trăm lẻ một

Please note that NGÀN is used in the Southern dialect and NGHÌN is used in the Northern dialect.

Million & Billion in Vietnamese

To review, in Vietnamese "ten" is CHỤC, "hundred" is TRĂM, and "thousand" is read as NGÀN In this lesson, we'll learn "million" is read as TRIỆU and "billion" is read as TỶ.

Why do we have to learn up until millions? You might know that the Vietnamese currency has lots of zeros. Therefore, you can reach billions easily, let's say when buying something expensive like a house in Vietnam.

Vietnamese Money & Currency

Before traveling to Vietnam, it is important to get familiar with Vietnamese Money and Currency. Việt Nam ĐỒNG is the Vietnamese currency, often represented as VNĐ or đ. Dollar in Vietnamese is ĐÔ. For instance, the US dollar would be read as "đô Mỹ".

Some conversions (as of Dec 2019) for comparison are:

• 1 USD / đô Mỹ = ~23,000 VNĐ
• 1 EUR / Ơ-rô = ~25,500 VNĐ
• 1 GBP / bảng Anh= ~30,500 VNĐ
• 1 CAD / đô Canada = ~17,500 VNĐ
• 1 AUD / đô Úc = ~16,000 VNĐ

Conversation Notes:

When talking about Vietnamese money, the locals often:

• omit the word NGÀN when the number is more than thousands. E.g. 100,000 = một trăm
• use CHỤC for Tens of Thousands. E.g 50,000 = năm chục
• use the word RƯỠI for half, especially when handling money. E.g. 250,000 = hai trăm rưỡi / 1,500,000 = một triệu rưỡi
• omit the word MỘT when it comes to 1 thousand, 1 million. E.g. 120,000 = trăm hai chục / 1,500,000 = triệu rưỡi
• omit saying all the zeros. E.g 2,200,000 = hai triệu hai (instead of hai triệu hai trăm)

Asking "How much" in Vietnamese

After knowing how to count and say Vietnamese money, let's learn how to ask how much something costs in Vietnamese with the 2 simple phrases below:

New Words:

• cái này ⇢ this one (used for something near)
