What “compatibility” means across these four tools
All four calculators on this page run on the same underlying method: Pythagorean name numerology, the letter-to-number system also used for personal numerology charts. Two names go in, each reduces to a core number, and the two numbers are compared. What changes between the tools is the question being asked of that comparison — a fast romantic spark and a decades-long marriage aren’t scored the same way, even from identical input.
Picking the right tool
The Love Compatibility Calculator by Name has all four relationship types built into one switcher, so you can compare friendship, love, partnership, and marriage results for the same two names without leaving the page. If you already know exactly what you’re checking, the three tools below open straight into that context instead.
When the three specific tools make more sense
Use the Friendship Test by Name when romance isn’t the question at all. Use the Marriage Compatibility Calculator by Name when you’re weighing something long-term. Use the Crush Test by Name when you just want a quick read on someone new, without the longer explanation.
A traditional system, not a scientific one
Numerology compatibility is a symbolic framework with centuries of tradition behind it, not a measurement backed by research. Treat every score on this site as a conversation starter or a moment of reflection — not a verdict on any real relationship.
