Zodiac Love Compatibility Calculator
The stars tell a story about every connection. Pick two signs — or enter two birth dates — and this calculator scores your romance, communication, and long-term potential using the same classical element and modality rules behind my full compatibility guides.
How Compatibility Scoring Works
This calculator uses classical astrological rules: signs of the same element share a natural resonance, harmonious elements (Fire-Air, Earth-Water) flow together, challenging elements (Fire-Water, Earth-Air) create friction that can become growth, and opposite signs form the most magnetic — and most demanding — axis in the zodiac. The full methodology is in my zodiac compatibility hub.
What the Score Means
A high score means the two signs have natural chemistry and shared rhythm. A challenging score is not a verdict — some of the most transformative relationships in astrology are built on friction, because each partner forces the other to grow. The score is the starting point, not the conclusion.
Sun Signs Are Just the Beginning
Sun sign compatibility tells you the potential between two signs. Your full birth charts — moon, rising, Venus, Mars — tell you the specifics of the connection. A live reading can compare your actual charts, identify the hidden friction points, and read the timing of the relationship. The astrology readers I've tested on Kasamba, Purple Garden, and Keen handle this work well, and all three offer introductory trial minutes.
