Love Compatibility Calculator
Check zodiac love compatibility between two signs or birthdays, with real astrology rules behind the score.
Two Fire signs share the same fuel — instant understanding. A trine — the easiest, most natural flow in astrology. Things just work.
Confident, generous, warm and dramatic. Loves the spotlight, celebration and loyalty.
Adventurous, optimistic, blunt and freedom-loving. Loves travel, big ideas and open horizons.
Just for fun:Astrology is entertainment, not science — signs don't determine personality or compatibility. Enjoy it the way you'd enjoy a fortune cookie.
What Is the Love Compatibility Calculator?
The Love Compatibility Calculator scores the match between two zodiac signs using traditional astrology rules: element harmony (Fire feeds Air, Earth grounds Water), and the aspect between the signs on the wheel — trines flow easily, opposites attract, squares bring friction. Enter two signs directly or two birthdays, and get a percentage with an explanation of why the pairing works the way it does.
How It Works
Pick both zodiac signs (or switch to birthday mode and enter two birth dates). The compatibility score, explanation and both signs' personality cards update instantly.
When to Use It
Use it for fun with a crush, a partner or friends — or to finally check whether a Leo and a Scorpio really are a handful together.
Frequently Asked Questions
- How is the score calculated?
- From classical astrology: signs sharing an element (or complementary ones like Fire + Air) score high, and the angle between signs matters — trines (4 apart) are smoothest, opposites are magnetic, squares (3 apart) are spicy. The same pair always gets the same score.
- What's the difference from the Love Calculator?
- The Love Calculator is a playful name-based score; this one uses zodiac signs and real astrological pairing rules. Try both and take whichever answer you like better.
