What is a Love Calculator?
The Love Calculator is a fun, just-for-entertainment tool that turns two names into a compatibility percentage between 40% and 99%. Type in your name and your partner's or crush's name — say, Rahul and Priya — and get an instant, shareable score. It's meant purely for amusement, not astrology or relationship science, and is a popular icebreaker on WhatsApp groups and college campuses across India.
How It Works
The two names are joined together, converted to lowercase, and stripped of spaces. Each letter's character code feeds a simple rolling hash, and the final number is mapped into the 40–99% range:
hash = (hash × 31 + charCode) % 100, repeated for every letter
compatibility % = 40 + (hash % 60)
Worked Example
Names: Rahul and Priya
Running the rolling hash across all 10 letters → hash % 60 = 19
Compatibility = 40 + 19 = 59% → 🤍 Average Match
Interestingly, entering the same two names in the opposite order — Priya first, Rahul second — changes the combined string to "priyarahul", producing a different hash and a score of 69% (❤️ Good Match). This is a quirk of how the character-by-character hash works: name order genuinely changes the result, so try both ways!
How to Use This Calculator
- Enter your name in the first field.
- Enter your partner's or crush's name in the second field.
- Click Calculate to reveal your compatibility percentage and match label.
Things to Know
- Scores always fall between 40% and 99% — the tool never shows 0% or 100%.
- Above 80% = Perfect Match, above 60% = Good Match, above 40% = Average Match, exactly 40% = Low Match.
- This is a novelty calculator for fun — treat the result as entertainment, not relationship advice.
