Expression Number Calculator
Your full name, turned into the three numbers numerology draws from it: expression (every letter), soul urge (vowels) and personality (consonants). Every step shown.
How the letters become numbers
Pythagorean numerology assigns each letter a digit from 1 to 9 in alphabetical cycles: A B C D E F G H I are 1 through 9, J through R are 1 through 9 again, and S through Z are 1 through 8. To get the expression number, add the values of every letter in each of your names, reduce each name to a single digit (keeping 11, 22 and 33 as master numbers), add those results, and reduce once more. The calculator does this name by name so you can see where each number came from.
The soul urge (sometimes heart's desire) repeats the calculation with vowels only: A, E, I, O, U. Y is treated as a vowel when it is the only vowel sound in a syllable (as in "Lynn") and a consonant otherwise; this calculator follows the simpler common rule and counts Y as a vowel when no other vowel is adjacent. The personality number uses the remaining consonants. Expression equals the two added together before reduction, which is a useful check.
Which name
Tradition says the full name on the birth certificate, middle names included, and that is what most published readings assume. Married names, nicknames and Anglicised spellings all change the result, which numerologists read as meaningful rather than as a problem. If your name uses letters outside A–Z (accents, non-Latin scripts), the calculator strips what it cannot map; transliterate first for a fuller result.
Reading the numbers
The meanings are the same single-digit and master-number set used across numerology; the life path calculator on this site lists them and has a page for each. The expression number is read as talents and tendencies, the soul urge as motivation, the personality as the face shown to strangers. All of it is interpretive. Numerology has no predictive track record; treat these as a vocabulary for thinking about yourself, not a measurement.
