The soul urge number, also called the heart desire number, is calculated from the vowels in your full birth name only. Each vowel takes a Pythagorean value from 1 to 9, the values are added, and the total reduces unless it is 11, 22 or 33. Consonants are ignored entirely.

The largest source of disagreement is the letter Y. Some systems treat it as a vowel always, some never, and some only where it carries the vowel sound, as in Lynn but not in Yolanda. This calculator applies the sound-based rule and marks each Y it counted, so you can see exactly which decision produced your number. The Chaldean system also assigns different values to letters entirely, which is a separate reason results differ between sites.
Take only the vowels from your full birth name, convert each to its Pythagorean value from 1 to 9, add them and reduce the total unless it is 11, 22 or 33. Consonants play no part. For JANE ELIZABETH SMITH the vowels give 35, which reduces to a soul urge of 8. The calculator lists each vowel and its value so the arithmetic is visible.
It depends on the system, and this is the biggest reason two sites give different answers. Some count Y always, some never, and some only where it carries the vowel sound, so counted in Lynn but not in Yolanda. This calculator uses the sound-based rule and marks every Y it counted, so you can see which decision produced your result and recalculate by hand if you prefer another rule.
They are two names for the same number, calculated the same way from the vowels of the birth name. Different traditions and different books favour different terms, and some sources add inner self as a third name. The multiplicity of names is a feature of numerology generally rather than a sign that different numbers are being described.
Traditional practice uses the full name as first recorded, on the basis that it is the name given rather than one adopted later. Some numerologists calculate the current name separately and compare the two, treating differences as a change in emphasis. Neither approach is authoritative, and our page on birth name against current name sets out both without picking one.
Short names simply give a smaller total, which reduces normally. No name in practice has no vowels at all once Y is considered, but names with few vowels produce a soul urge from a very small sample, which is worth knowing when weighing how much the result means. The calculation is arithmetically valid either way.
