Question 1

How is name numerology calculated?

Accepted Answer

Each letter maps to a digit 1–9 in the Pythagorean system: A J S = 1, B K T = 2, C L U = 3, D M V = 4, E N W = 5, F O X = 6, G P Y = 7, H Q Z = 8, I R = 9. Add every letter for the Expression number, only the vowels for the Soul Urge number, and only the consonants for the Personality number, then reduce each total.

Question 2

Which name should I use — my married name or my birth name?

Accepted Answer

Use your full birth name exactly as it appears on your birth certificate, including middle names. That is the name the core numbers are derived from. A changed name can be calculated separately as a secondary influence, but it does not replace the birth chart.

Question 3

Is Y a vowel in numerology?

Accepted Answer

Sometimes. Y counts as a vowel when it is not preceded by another vowel — so it is a vowel in 'Lynn' but a consonant in 'Riley'. This calculator applies that rule automatically and marks each letter in the breakdown.

Question 4

Why does another site give me different numbers?

Accepted Answer

Almost always because it uses the Chaldean system rather than Pythagorean, or because a different form of your name was entered. This calculator shows every letter and its value so you can see exactly where any difference comes from.
