The Numerology Compatibility Calculator compares two people by their Life Path number — the most important number in numerology, worked out from the full date of birth. Enter both birthdays and get a compatibility score out of 100, along with what naturally works between you and what may take a little effort.

What is the Life Path number?

Your Life Path number describes your core personality and the journey your life tends to take. It is found by adding up all the digits of your birth date and reducing them to a single digit from 1 to 9 — except the master numbers 11, 22 and 33, which are kept as they are because they carry a stronger, higher vibration.

How the match is scored

Each Life Path number has its own strengths and natural style. Some numbers share an easy rhythm, some balance each other, and some are more contrasting and need understanding. The calculator looks up how the two Life Path numbers relate and turns that into a score, a verdict, and short notes on what works and what to watch. Master numbers are compared using their base number (11→2, 22→4, 33→6).

Is the Life Path the whole story?

No — it is a fun, big-picture guide. A complete numerology comparison would also look at the Destiny (Expression) number, the Soul Urge number, and the birthday number of each person. For an in-depth reading, consult a professional numerologist.
