Free Relationship Compatibility Calculator
Compatibility is not a score — it is a chemistry. When two birth charts are compared (a technique called synastry), you can see where two people flow, where they spark, and where they are each other's teachers. Enter both birth details below for a balanced look at this connection.

Frequently Asked Questions
What is synastry in astrology?
Synastry compares two birth charts to see how each person's planets land in the other's chart. Flowing aspects show ease; harder aspects show growth edges. Together they describe the relationship's dynamics.
Can a calculator tell me if someone is my soulmate or twin flame?
No honest reading can. Compatibility tools describe indicators — areas of ease, attraction patterns, emotional dynamics. Labels like "soulmate guaranteed" belong to marketing, not astrology.
What are the most important compatibility placements?
Connections between one person's planets and the other's Sun, Moon, Venus, and Rising tend to carry the most weight — they touch identity, emotional needs, love style, and first impressions.
Do challenging aspects mean a relationship will fail?
Not at all. Squares and oppositions create attraction, growth, and staying power when both people are willing to grow. The best long-term connections usually include both ease and friction.
