What Is the Love Compatibility Calculator?

No sign-up. No data storage. Just instant results.

How the Love Compatibility Calculator Works

Our system uses a multi-factor model to evaluate compatibility from both emotional and practical perspectives:

1. Western Zodiac Compatibility (25%)

Using your birth dates, we identify your Sun signs and analyze elemental harmony:

Fire (Aries, Leo, Sagittarius): Passionate and energetic
Earth (Taurus, Virgo, Capricorn): Practical and grounded
Air (Gemini, Libra, Aquarius): Intellectual and communicative
Water (Cancer, Scorpio, Pisces): Emotional and intuitive

Best Element Pairings

Fire + Air → Passionate and exciting
Earth + Water → Stable and nurturing
Same elements → Deep mutual understanding

2. Chinese Zodiac Compatibility (20%)

Your birth year determines your Chinese zodiac animal (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig). Traditional Chinese astrology highlights harmonious pairings as well as challenging combinations.

3. Numerology Life Path Compatibility (15%)

We calculate each partner’s Life Path number from the birth date, revealing personality traits and life goals. Master Numbers (11, 22, 33) are also identified for deeper spiritual insight.

4. Name Numerology (15%)

Using Pythagorean numerology, we analyze:

Letter vibration values
Name length balance
Overall energetic harmony between names

5. Age Compatibility (15%)

Age difference is evaluated using proven relationship heuristics:

0–5 years → Ideal compatibility
5–8 years → Strong compatibility
8–12 years → Moderate compatibility

6. Biorhythm Synchronization (10%)

Current alignment of physical (23-day), emotional (28-day), and intellectual (33-day) cycles is calculated to reflect short-term relationship timing and energy alignment.
