How to Calculate Your Numerology Numbers: A Step-by-Step Guide

Numerology calculations may seem complex at first glance, but the Pythagorean system — the most widely used method in Western numerology — follows a simple and elegant set of rules. Once you understand the basics, you can calculate any core number from a name or birth date.

The Pythagorean Number Chart

In the Pythagorean system, each letter of the alphabet is assigned a number from 1 to 9. A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8, I=9, then J=1, K=2, and so on. This cycle repeats through the entire alphabet. Write out your full birth certificate name and assign each letter its corresponding number.

Calculating the Expression (Destiny) Number

Add together the numerical values of every letter in your full birth name. Reduce the total to a single digit or Master Number. This is your Expression Number, also called the Destiny Number. It reveals your natural abilities, talents, and the person you are meant to become over the course of your life.

Soul Urge and Personality Numbers

The Soul Urge Number uses only the vowels in your name (A, E, I, O, U). Add them up and reduce. This number reveals your innermost desires and motivations — the things that drive you at the deepest level. The Personality Number uses only the consonants and shows how others perceive you. Together, these numbers complete your core numerology profile and provide a comprehensive understanding of who you are.
