Astrological compatibility traditions evaluate relationships by comparing the elemental groupings (Fire, Earth, Air, and Water) and triplicities of two partner zodiac signs. Shared elements and complementary elemental pairings are considered harmonious, while opposing elements require intentional communication.

This interactive calculator models compatibility between any two zodiac signs using elemental rules: - Signs sharing the exact same element (Fire+Fire, Earth+Earth, Air+Air, Water+Water) score a baseline harmony of 92%. - Complementary elemental combinations (Fire with Air, Earth with Water) score a baseline harmony of 88%. - Different or contrasting elemental pairings score a baseline harmony of 64%. - When both partners share the exact same zodiac sign, baseline harmony is calibrated to 82%. - Final overall scores incorporate a standard +2% affinity adjustment (capped at 99%).

### A Real Example You evaluate compatibility between Leo (a Fire sign) and Sagittarius (also a Fire sign). Because both signs belong to the Fire triplicity, the elemental harmony baseline evaluates to 92%. With the affinity adjustment applied, the tool reports a 94% love compatibility score, noting high energetic resonance and shared optimism.
