How to Calculate Your Name Number in Chaldean Numerology
This gives you the Chaldean value of any name, letter by letter, with the arithmetic shown so you can check it. You only need the spelling you actually use day to day.
The manual method
- Write your name in the spelling you actually use — the one on your signature and your everyday documents, not a formal version nobody says out loud.
- Replace each letter with its Chaldean value: A, I, J, Q, Y = 1. B, K, R = 2. C, G, L, S = 3. D, M, T = 4. E, H, N, X = 5. U, V, W = 6. O, Z = 7. F, P = 8. Chaldean assigns no letter the value 9.
- Add every letter value together. That total is your compound number, and it carries meaning of its own.
- Reduce the total by adding its digits, repeating until one digit remains. That single digit is your name number.
Worked example — Aarav Mehta
- Letters: A=1, A=1, R=2, A=1, V=6, M=4, E=5, H=5, T=4, A=1
- Total: 1 + 1 + 2 + 1 + 6 + 4 + 5 + 5 + 4 + 1 = 30
- 3 + 0 = 3
- Name number: 3
The same name in both systems — Aarav Mehta
- Chaldean: A=1, A=1, R=2, A=1, V=6, M=4, E=5, H=5, T=4, A=1 = 30 → 3 + 0 = 3 → 3
- Pythagorean: A=1, A=1, R=9, A=1, V=4, M=4, E=5, H=8, T=2, A=1 = 36 → 3 + 6 = 9 → 9
- Aarav Mehta comes out as 3 in Chaldean and 9 in Pythagorean. Neither is a mistake. The two systems assign letters differently — Pythagorean numbers them by alphabetical position and uses 9, while Chaldean is based on sound and never gives 9 to a letter — so the same name legitimately produces two figures. If another site gave you a different number from ours, this is almost always why. Everything on this site, including the paid reports, uses Chaldean.
- Pythagorean letter values: 1 — A, J, S; 2 — B, K, T; 3 — C, L, U; 4 — D, M, V; 5 — E, N, W; 6 — F, O, X; 7 — G, P, Y; 8 — H, Q, Z; 9 — I, R
What this number does not tell you
A name number describes the impression a name makes, not a fixed fate. Chaldean and Pythagorean produce different numbers because they assign letters differently — neither is a mistake, they are separate systems, and a number is only meaningful alongside the one it is calculated with.
Frequently Asked Questions
Why does Chaldean never use the number 9?
In the Chaldean system 9 is treated as sacred and is not assigned to any letter. It still appears as a result when a total reduces to 9 — it simply is not given to a letter directly. Pythagorean numerology does assign 9, which is one reason the two systems disagree on the same name.
Should I use my full legal name or my short name?
Use the name people actually call you and that you sign. Chaldean numerology weighs the name in active use, so a formal name that never gets spoken carries less relevance than the one on your everyday signature.
Does the surname count?
Include it if you use it routinely. Many people calculate the first name alone for personal character and the full name for public and professional matters — calculate both if you are unsure, since they answer slightly different questions.
