Swahili Numbers 1 to 100: The Simple Way to Count

Most languages make numbers a chore. Swahili almost makes them a game.

Once you learn the numbers 1 to 10 and a single joining word, you can build every Swahili number up to 100 — and beyond — like clicking Lego bricks together. No irregular spellings to memorise, no tricky exceptions like English's "eleven" and "twelve." Just a clean, logical pattern.

This guide walks you through Swahili numbers 1 to 100 step by step, with pronunciation you can trust and the one rule that unlocks the whole system. By the end, you'll be counting out loud.

The one pattern that unlocks Swahili numbers

Here's the whole trick: Swahili builds bigger numbers by joining smaller ones with the word na, which means "and."

Ten is kumi. One is moja. Eleven? Kumi na moja — literally "ten and one." Twenty-one is ishirini na moja — "twenty and one." That's it. Learn the units, learn the tens, and glue them together with na.

Master that, and the numbers 1 to 100 stop being a list to memorise and become a system you can generate on demand.

Swahili numbers 1 to 10

Start here. These are the building blocks for everything else. Moja (1) — say MOH-ja. Mbili (2) — say m-BEE-lee. Tatu (3) — say TAH-too. Nne (4) — say N-neh. Tano (5) — say TAH-no. Sita (6) — say SEE-ta. Saba (7) — say SAH-ba. Nane (8) — say NAH-neh. Tisa (9) — say TEE-sa. Kumi (10) — say KUU-mee.

A couple of pronunciation notes. Mbili (2) starts with a soft "m" before the "b" — let it hum briefly, m-bee-lee. Nne (4) doubles the "n," so hold it a touch longer than you would in English. Everything else is said exactly as written.

Swahili numbers 11 to 19

Now the pattern kicks in. Take kumi (10), add na ("and"), then the unit. 11 is kumi na moja (ten and one). 12 is kumi na mbili. 13 is kumi na tatu. 14 is kumi na nne. 15 is kumi na tano. 16 is kumi na sita. 17 is kumi na saba. 18 is kumi na nane. 19 is kumi na tisa.

No new words to learn. If you know 1 to 10, you already know 11 to 19. Compare that to English, where "eleven," "twelve," and "thirteen" each demand separate memorising.

The tens: 20, 30, 40 up to 90

The tens are their own set of words, and this is the only real memorisation in the whole system. Ishirini (20) — say ee-shee-REE-nee. Thelathini (30) — say theh-lah-THEE-nee. Arobaini (40) — say ah-ro-BAH-ee-nee. Hamsini (50) — say ham-SEE-nee. Sitini (60) — say see-TEE-nee. Sabini (70) — say sa-BEE-nee. Themanini (80) — say theh-mah-NEE-nee. Tisini (90) — say tee-SEE-nee. Mia moja (100) — say MEE-ah MOH-ja.

You'll notice several of these echo the units: sitini (60) and sita (6), sabini (70) and saba (7), tisini (90) and tisa (9). Those overlaps make them easier to remember than they first look.

Many of the tens (and some units like sita, saba, tisa) trace back to Arabic influence on Swahili — a reminder of the language's rich history along the trading coast of East Africa.

Putting it together: 21 to 99

This is where it all clicks. Any two-digit number is just [ten] na [unit]. 21 is ishirini na moja (twenty and one). 34 is thelathini na nne (thirty and four). 47 is arobaini na saba (forty and seven). 56 is hamsini na sita. 68 is sitini na nane. 72 is sabini na mbili. 89 is themanini na tisa. 99 is tisini na tisa (ninety and nine).

See the logic? Once you can say the nine tens and the nine units, you can produce every number from 21 to 99 without learning anything new. That's the beauty of the system — and a big reason beginners find Swahili numbers so satisfying.

Reading a table is one thing; saying "sitini na nane" smoothly when someone tells you a price is another. That fluency comes from counting out loud with someone who can correct you in the moment. You can try a free Swahili lesson with a native tutor and practise counting with a native speaker until it's automatic.

And 100 — mia moja

One hundred is mia moja — literally "one hundred." From there the same na pattern continues. 100 is mia moja. 101 is mia moja na moja (one hundred and one). 150 is mia moja na hamsini (one hundred and fifty). 200 is mia mbili (two hundreds). 656 is mia sita na hamsini na sita (six hundreds and fifty and six).

The word na keeps joining the pieces — hundreds to tens, tens to units. Learn the pattern once and it scales as high as you need.

A quick grammar note (don't worry, it's small)

In careful Swahili, a few numbers change their form to agree with the noun they count — mainly moja (1), mbili (2), tatu (3), nne (4), tano (5), and nane (8). So "one book" and "one child" can shift the "one" slightly. The other numbers stay the same no matter what they count.

For counting out loud — prices, phone numbers, ages, scores — you can use the plain forms above and be perfectly understood. The agreement rules come naturally once you're speaking in full sentences, and a tutor will guide you into them without you having to memorise a chart.

Frequently Asked Questions

What are the numbers 1 to 10 in Swahili?

The Swahili numbers 1 to 10 are: moja (1), mbili (2), tatu (3), nne (4), tano (5), sita (6), saba (7), nane (8), tisa (9), and kumi (10). These are the building blocks for every larger number.

How do you count to 20 in Swahili?

After 10 (kumi), you add na ("and") plus the unit: 11 is kumi na moja, 12 is kumi na mbili, and so on up to 19 (kumi na tisa). Twenty is its own word: ishirini.

How do you say numbers between 21 and 99 in Swahili?

Combine the ten with na ("and") and the unit. For example, 21 is ishirini na moja (twenty and one) and 68 is sitini na nane (sixty and eight). Once you know the tens and units, you can build any number in this range.

Are Swahili numbers hard to learn?

No — Swahili numbers are among the easiest parts of the language. There are no irregular forms like English's "eleven" or "twelve"; you simply join units and tens with na ("and"). Most learners count to 100 confidently within a lesson or two. See is Swahili hard to learn for the fuller picture.

What is 100 in Swahili?

One hundred is mia moja. Higher hundreds follow the same pattern: 200 is mia mbili, 300 is mia tatu, and you join smaller numbers with na — for example, 150 is mia moja na hamsini.

Now count it out loud

You've just learned a system, not a list. Ten units, nine tens, one joining word — na — and Swahili numbers 1 to 100 are yours. From moja to mia moja, it's one of the most logical counting systems you'll ever meet, which is exactly why beginners love it.

The last step is the fun one: say them out loud until they flow. Book a free first lesson with a native Swahili tutor and count your way to confidence — moja, mbili, tatu, twende!
