Read the expression numbers →How name numerology actually works
Every letter is given a number between 1 and 9, the numbers are added, and the total is reduced until one digit is left. That is the whole mechanism. Everything else is interpretation.
The chart itself is the least mysterious part of numerology. A runs to 1, B to 2, and the alphabet keeps counting until it reaches 9 at I, then starts again at J. Three passes cover 26 letters with two to spare, which is why the ninth column holds only I and R. This layout is usually credited to Pythagoras and almost certainly is not his: the version in use today was codified in the United States in the twentieth century, largely through the work of L. Dow Balliett and later Juno Jordan.
Reduction is the second rule. A name totalling 79 becomes 7 + 9, then 16, then 1 + 6, then 7. The exception is the three master numbers. If a total lands on 11, 22 or 33, most numerologists stop there and read the double digit whole. That single convention is responsible for most of the disagreements between calculators, along with the letter Y.

Read down the columns and the pattern is obvious: 1 collects A, J and S because they sit nine letters apart. The only column that comes up short is 9, which gets I and R and nothing else, because the alphabet runs out.
That shortage has a real consequence. A name reaches a high consonant total mostly through R, and reaches a high vowel total mostly through I, since those are the only letters in their halves worth 9. Vowels are the more constrained side by far: A, E, I, O, U and Y carry just six values between them, 1, 5, 9, 6, 3 and 7.
E is the most frequent letter in written English and it is worth 5. That one fact tilts the whole distribution of Soul Urge numbers, which is why some results are common and others take an unusual name to reach.
The three numbers, and what separates them
Vowels only
Soul Urge
What they want when nobody is watching. Motive rather than method, and the number most sensitive to the Y rule.

Personality
What a room registers in the first minute. The doorway, not the room behind it.
Read the personality numbers →The Y rule, stated once
Y is worth 7, and 7 is a large value to move between two halves of a name. Counting Y as a vowel in Lynn adds 7 to the Soul Urge and takes 7 off the Personality, which is often enough to change both numbers at once.
Three conventions circulate. Some numerologists count Y as a vowel always. Some use a syllable rule, counting it as a vowel when its syllable contains no other vowel, which needs a pronunciation dictionary and gives different answers in different accents. This site uses the positional rule below, because it is deterministic and you can check it yourself on any name in a second.
W gets the same question in a few older books, which treat it as a vowel in pairs like ow and aw. We do not. W is always a consonant here.
- Y is a vowel unless the next letter in the same word is A, E, I, O or U
- Lynn, Kyle, Mary, Yvonne, Wyn
- Yolanda, Maya, Bryan, Yasmin
- 7, the same as G and P
- Always a consonant, worth 5
- Stripped before counting, so José counts as JOSE
What a name change does, and does not do
Marriage, adoption, transition, a stage name, a pen name: all of them change what the letters add up to. The tradition handles this by keeping the birth name as the base chart and reading the current name as a layer on top, so a person can hold two Expression numbers at once without contradiction.
What it does not do is make anything happen. Nobody should pick a name, a spelling or a business name because a total came out at 8 rather than 4, and we will not tell you that one number is luckier than another. There is no evidence that letter arithmetic predicts anything about a life. What it reliably gives you is a fixed vocabulary and a starting point for thinking about yourself, which people have found useful for a hundred years without it needing to be true.
The calculator above keeps every step visible for exactly that reason. You can see where the arithmetic ends and where the reading begins, and you can disagree with the second half while checking the first.
Name numerology — frequently asked
The birth certificate name, including middle names, is what the standard method asks for. Numerologists treat it as the full chart and read a married name, a stage name or a chosen name as a second, later layer rather than a replacement. Both are worth calculating if you want them. Nothing about the method says which one is more real.
Both, depending on the word. This calculator counts Y as a vowel unless the next letter in the same word is A, E, I, O or U, so it is a vowel in Lynn and Mary and a consonant in Yolanda and Maya. Books that use the older syllable rule will disagree with us on some names, and we would rather show you the rule than hide the disagreement.
Because each half is reduced before anyone compares them. Reduce first, add second, and the arithmetic no longer lines up. It is a known wrinkle in the method rather than an error in the sums.
It changes what the letters add up to, which is all a numerologist can honestly claim. The tradition reads a new name as a new outer chart laid over the birth one. It does not make anything happen, and nobody should choose a name on the strength of a total.
No, in the sense you probably mean. There is no evidence that letter totals predict anything about a person, and this site does not pretend otherwise. What the tradition offers is a fixed, checkable procedure and a vocabulary for talking about yourself. We show every step so you can see exactly how much arithmetic there is and exactly where the interpretation starts.
Different letter values. Pythagorean runs the alphabet through 1 to 9 in order, which is the system on this page. Chaldean assigns values by sound rather than sequence and never uses 9 for a letter at all, so the two systems routinely give different answers for the same name.
