English Numbers: The Complete Chart, How to Say Money and Zero

At the checkout counter at the airport, the cashier says one very short sentence: "That'll be fifteen fifty". You hear fifty fifty and reach for your wallet based on the number in your head. That sentence lasts under two seconds and it doesn't repeat.

Numbers are the group of words taught in the very first lesson, and they still get misheard after years. The reason isn't memory. In an ordinary sentence, if you miss a word, grammar and context patch it for you. Numbers have no such patch. Thirteen dollars and thirty dollars are both grammatically correct, both plausible, both could be the price of the same item. Miss it by ear and you lose it outright — nothing left to guess from.

This page has two halves. The first half is a reference table: how to write, how to say, and the phonetic transcription of numbers from 0 to the billions, plus the spots where Vietnamese speakers usually slip when combining numbers. The second half is for the ear, and that's the part you should actually read carefully.

Counting numbers table 0 to 20

The first twenty words have to be memorized, because they don't follow any pattern at all. From 21 onward, everything is just combination. The transcriptions below are given in British English.

From 21 to 99, numbers combine following exactly one pattern: round ten, hyphen, unit digit. 21 is twenty-one, 47 is forty-seven, 99 is ninety-nine. The hyphen is mandatory in standard written English.

Round tens, hundreds, thousands, millions, billions

The round-tens group causes the most trouble for the ear, because every word here has a sibling ending in -teen. You'll meet those exact seven pairs again in the listening section.

Combining large numbers: four places people slip

The four points below cause far more errors than memorizing the table, because they go against Vietnamese habits.

1. hundred, thousand, million don't take an s when a number comes before them. You say two hundred students, five thousand people, three million users. The form two hundreds is wrong.
2. But they do take an s when used with of and no specific number. hundreds of people means just that — hundreds of people, thousands of years means thousands of years. Here the s is mandatory.
3. The British and. 350 is read as three hundred and fifty in the British style, three hundred fifty in the American style. Both are correct — you just need to know that and can show up, so your ear doesn't lose the beat.
4. The comma and the period are swapped compared with Vietnamese. English writes 1,500.75 while Vietnamese writes 1.500,75. The comma separates thousands, the period opens the decimal part. Misreading the punctuation throws you off by a factor of a thousand.

For long numbers, people break them into groups of three digits and read left to right. 1,234,567 is read as one million, two hundred and thirty-four thousand, five hundred and sixty-seven. It sounds long, but the structure repeats, so the ear picks it up fast.

The 1,200 row deserves special attention. Americans read twelve hundred for round-hundred numbers from 1,100 to 1,900, and that's the kind of reading that leaves learners frozen because there's no thousand anywhere to be found.

The number 0 and its five names

No number in English has as many names as 0. Pick the wrong name and the listener still understands, but if you can't make out which name they're using, you lose the number entirely.

A quick way to remember it: zero is the safe default everywhere except sports. oh shows up when the number is read digit by digit. nil, love, and nothing belong to the football pitch and the tennis court — you meet them in sports broadcasts, rarely in work conversation.

Decimals, money, phone numbers, years

Decimals

The period is read as point. The part before the point is read as an ordinary number, the part after the point is read digit by digit. 3.14 is three point one four, not three point fourteen. 2.5 is two point five. 0.75 has three usable readings: zero point seven five, nought point seven five, or, most compact, point seven five.

Money

Money doesn't use point. You don't say four point five zero dollars. There are three ways to read it, ranging from formal to everyday.

The shortest column is the one you'll hear most in real life, and also the most dangerous one, because four fifty and four fifteen differ by only one final sound.

Phone numbers

Phone numbers are read digit by digit, broken into groups, and 0 is read as oh. The British combine repeated digits using double and triple: 44 becomes double four, 777 becomes triple seven. Americans typically read each digit separately and tend to use zero instead of oh. When giving someone your number, reading slowly and pausing after every three to four digits is enough for the other person to keep up while writing it down.

Years

Years are split into pairs of two digits. 1975 is nineteen seventy-five, 1900 is nineteen hundred, 1905 is nineteen oh five. From 2000 to 2009 the pattern changes: 2000 is two thousand, 2007 is two thousand and seven. From 2010 onward it goes back to the paired style, so 2026 is twenty twenty-six. The way years are said runs very close to how dates are said in English, and the day of the month takes the ordinal form rather than the counting form, meaning you'll also need the ordinal numbers table to have the complete set.

Telling time also runs on these same numbers, just combined differently: how to tell time in English has its own past and to parts that the numbers table alone doesn't fully cover.

Thirteen or thirty: three signals to tell them apart

This is the costliest pair to confuse in English. It shows up in prices, ages, quantities, appointment times, house numbers, and every time you mix them up, you misunderstand something real — not just get an exercise sentence wrong.

The first signal is stress. When the word stands alone, thirteen puts the weight on the second part, sounding like thir-TEEN. thirty puts the weight on the first part, sounding like THIR-ty. This is the most commonly taught signal, and also the one that betrays you most often.

Why it betrays you. When thirteen comes before a noun, the stress jumps to the front to avoid two stresses colliding. thirTEEN on its own, but THIRteen dollars when a noun follows. Exactly when you need to tell them apart the most — when the number comes with a unit — the stress signal fades. This phenomenon belongs to the family of changes in connected speech, and connected speech has plenty more tricks like it.

The second signal is the final sound, and this is the one you can actually trust. The -teen ending always closes with the consonant /n/. The -ty ending always finishes on the vowel /i/, mouth open, nothing blocking it. Stress can shift, but that /n/ sound doesn't disappear. Training your ear to latch onto the ending instead of the beginning is the most useful change you can make for this group of words.

The third signal is the t in the middle. In American accents, a t sitting between two vowels gets softened into a sound close to /d/, so thirty sounds like thir-dy. The t in thirteen keeps its full plosive force, because it starts the syllable that carries the stress. Hear a soft, d-like sound and it's almost certainly a round-ten number.

Even native speakers confuse this pair. When they need to be sure, they ask back by spelling out the digits: "Fifteen, one five, or fifty, five oh?" You can use that exact question yourself — it won't give away that you're a learner at all.

A fifteen-minute number dictation exercise

Listening for more hours doesn't fix this problem. When you listen for the gist, your brain is allowed to skip over numbers and still follow the story, so your ear is never forced to discriminate between them. What does force it is dictation listening: transcribing word for word leaves no room to guess.

1. Pick a talk dense with numbers. Economic news, sports news, and conversations about booking appointments or making purchases are places where numbers keep coming up.
2. Listen sentence by sentence and transcribe it. For any number you're unsure of, just write down what you heard — don't stop to reason it out.
3. Compare against the transcript. Circle every mistake that's a number, separately from other errors.
4. Listen to those exact sentences again, this time knowing the answer beforehand. You're teaching your ear to link the sound with the correct number.
5. Add the pairs you keep confusing to a review list, then revisit them a few days later instead of drilling them all in one sitting.

At WELE, every sentence you transcribe is graded word by word, so a wrong number stands out clearly instead of getting lost in the rest. A library of more than 800 podcasts with transcripts is enough for you to filter out just the ones packed with figures. Mistranscribed spots get pulled into review using spaced repetition, meaning you come back right when the memory is about to fade. Fifteen minutes a day is enough, and how to fit a lesson into fifteen minutes already has a schedule laid out for busy people.

If you want to know your current listening level before you start, the free listening level test gives you a baseline to compare against a few weeks later. And if mishearing happens to you everywhere, not just with numbers, three reasons why Vietnamese speakers have poor listening skills gets straight to the root of it.

What learners often ask about numbers

Is 0 said zero or oh, and when do you use which?

Use oh when the number is read digit by digit, for example phone numbers, room numbers, years. Use zero when the number carries a mathematical value, for example temperature, scores, calculation results. Mixing these up doesn't cause misunderstanding, but getting it right makes what you say sound far more natural.

Two hundreds or two hundred?

two hundred. When a number comes right before them, hundred, thousand, million, and billion all stay in the singular form. Only when you're speaking approximately with of do you add an s, as in hundreds of emails.

How should 1,500 be read naturally?

Both one thousand five hundred and fifteen hundred are correct. The second is more compact and very common in American English, especially when talking about money or distance. When reading numbers in formal writing, go with the first.

How do you say $4.50 like a native speaker?

four fifty. People drop both dollars and cents entirely in everyday buying and selling conversation. The full form four dollars and fifty cents only shows up when absolute clarity is needed, for instance when reading out a bill over the phone.

Numbers go by too fast to catch — what now?

Transcribe it instead of trying to understand it. Listen to a sentence with a number, write it down on paper, compare it against the original. The problem isn't speed — it's that your ear has never been forced to choose between two similar sounds. If you're starting over from scratch, the roadmap for learners starting from zero lays out the order of things to do.

Wrapping up

You can memorize the numbers table in this article in one sitting, but training your ear to catch fifty in the middle of fast speech takes weeks of transcribing, over and over. Pick a podcast episode with figures in it, transcribe it sentence by sentence, and every time you get a number wrong, note down that pair. A few dozen rounds of that is enough for you to hear fifteen fifty at the checkout counter next time without having to ask again. Start for free with WELE's library of podcasts with transcripts.
