What is Life Path compatibility?

Life Path compatibility compares two Life Path numbers, the single number each person's birth date reduces to in Pythagorean numerology. Soulmath sorts the nine numbers into four vibe groups and scores each pairing by how those groups relate. It describes how two friends tend to move together. It is not a verdict on the friendship.

Which Life Path numbers are most compatible?

In Soulmath's model the highest Life Path term, 80, goes to two different numbers from the same vibe group: 1 and 8, 2 and 6, 2 and 9, 3 and 5, 4 and 7 and 6 and 9. Two people with the same number score 75. No pairing scores below 60, and a lower number marks more friction to talk about, not a friendship to avoid.

How do I work out numerology compatibility from two birthdays?

Reduce each birth date to its Life Path number: reduce the month, the day and the year separately, add the three, then reduce the total, keeping 11, 22 and 33 intact. Find both numbers on the chart for the Life Path term. A live Soulmath compare then adds a small term for matching Birthday numbers and for master numbers. The calculator does all of it from two birthdays and shows each step.

Why do 3 and 7 score the same as 7 and 3?

Because the arithmetic is symmetric. The score for a pairing does not depend on who is asking. The advice does, which is why most pairings have two pages: one written for each person in the friendship.

Where are master numbers 11, 22 and 33 on the chart?

Life Path 11 has its own row under the main chart, with a page for each pairing. For grouping, the engine places 11 with 2, 22 with 4 and 33 with 6, so 22 and 33 read off the 4 and 6 rows. A live compare keeps the master number unreduced and adds a small master-number term. The Life Path 11, 22 and 33 guides cover how those numbers show up in friendships.

Does a low score mean we should not be friends?

No. The lowest Life Path term on the chart is 60, and it marks opposite vibe groups: more friction, and usually more to learn from each other. Soulmath describes dynamics between friends. It does not rate whether a friendship is worth having.

Find your Life Path down the side and your friend’s along the top. Each value is the Life Path term out of 100, the largest single piece of a Soulmath compare. It is the same number for every pair of people with those two Life Paths.

Life Path 11 compatibility chart

Life Path 11 is a master number and is never reduced in a reading. For this one step the model places it through the 2 underneath it, in the heart group, which is why 11 with 2 lands in the shared-number band.

80Same vibe group, different numbers: Strong resonance. You want similar things from a friendship and go about it slightly differently.
75The same number twice: Comfortable and instantly familiar, marked down a little because nobody covers the blind spot.
70Neighbouring vibe groups: Complementary. Each of you covers something the other tends to skip.
60Opposite vibe groups: The high-friction, high-interest band. More to negotiate, usually more to learn.

The chart is symmetric: 3 and 7 score the same as 7 and 3. The pages below are not. Each one is written for the person reading it.

The method

How Soulmath scores Life Path compatibility

Each birthday reduces to a Life Path number using the Pythagorean method: reduce the month, the day and the year separately, add the three, then reduce the total. Master numbers 11, 22 and 33 are never reduced. The calculation guide walks through it with worked examples.

The nine single-digit Life Paths sit in four vibe groups, arranged in a cycle so neighbours complement each other and opposites create the most friction. The Life Path term comes from how the two groups relate, which is why the chart only ever shows four values.

drive: Life Path 1 and 8. Leans toward drive and initiative.
heart: Life Path 2, 6 and 9. Leans toward attunement and care.
spark: Life Path 3 and 5. Leans toward expression and change.
roots: Life Path 4 and 7. Leans toward structure and depth.

A live compare uses two full birthdays, so it adds two smaller terms on top: a couple of points when both Birthday numbers reduce to the same digit, and a few more when a master number is present. The total is capped at 100, and every term is shown on the result.

None of this is a forecast. It is a consistent way to start a conversation about how two friends work, with arithmetic you can check. The method page covers the sources and the limits.
