Love Calculator
Enter two names for a fun love-compatibility percentage and the classic FLAMES result — then learn how the game works and how love-matching traditions differ around the world.
A love calculator turns two names into a fun compatibility score. Ours is deterministic — the same names always give the same percentage and the same FLAMES outcome (Friends, Love, Affection, Marriage, Enemy or Siblings). It is for entertainment only and is not a scientific measure of a relationship.
How a Love Calculator Works
Almost every online "love meter" works by converting the two names into a number. The honest difference between them is whether that number is random (it changes each time you click) or deterministic (it is derived only from the names, so it never changes). Ours is deterministic and order-independent: "Alex + Sam" and "Sam + Alex" always return the same score, so the result is fair to compare and fun to share.
Under the hood we normalize both names to lowercase letters, join them in a fixed (sorted) order, and run a stable hash that maps the pair to a percentage between 0 and 100. None of this is a measurement of real chemistry — it is the same kind of name-game people have played on paper for generations.
The FLAMES Game Explained
FLAMES is a classic playground game across South and Southeast Asia. The letters stand for:
- F — Friends
- L — Love
- A — Affection
- M — Marriage
- E — Enemy
- S — Siblings
To play by hand: write both names, strike out every letter they share (one-for-one), and count the letters left over. Then count that many letters around F-L-A-M-E-S, removing the one you land on, and repeat until a single letter — your relationship label — remains. Our calculator does exactly this for you.
Love & Compatibility Traditions Around the World
Name-based games are just one of many cultural ways people explore compatibility. Here is how the idea shows up across countries:
| Tradition | Region | Based On |
|---|---|---|
| FLAMES | India, Pakistan, Bangladesh, Philippines | Letters shared between two names |
| Bazi / Zodiac matching | China & East Asia | Birth year, month, day & hour ("eight characters") |
| Gung-hap (궁합) | South Korea | Traditional birth-chart marriage reading |
| Ketsueki-gata (血液型) | Japan | Blood-type personality matching |
| Numerology | Western pop culture | Numeric values assigned to name letters |
| Sun-sign astrology | Western pop culture | Zodiac sign from birth date |
All of these are cultural pastimes enjoyed for fun — none is a scientific predictor of a relationship.
Frequently Asked Questions
Is the love calculator real or accurate?
No — a love calculator is for fun and entertainment, not a scientific measure of compatibility. Our version is deterministic, meaning the same two names always produce the same percentage and FLAMES result, so it is consistent and shareable. Real relationship compatibility depends on communication, values and trust, not the letters in your names.
How does a love calculator work?
Most online love calculators turn the two names into a number. Ours normalizes both names (lowercase letters only), combines them in a fixed order so "A + B" equals "B + A", and runs a stable hash to produce a score from 0 to 100%. It also plays the classic FLAMES game by cancelling shared letters and counting out F-L-A-M-E-S. Because the method is fixed, results never change between visits.
What does FLAMES mean?
FLAMES is a pen-and-paper game popular across India, Pakistan, Bangladesh, the Philippines and other parts of Asia. The letters stand for Friends, Love, Affection, Marriage, Enemy and Siblings. You write both names, strike out the letters they share, count the remaining letters, and use that count to eliminate the FLAMES letters one by one until a single relationship label remains.
Why do I get the same result every time?
Unlike random "love meters", our calculator is fully deterministic. The percentage and FLAMES outcome are derived only from the two names, so the same pairing always returns the same answer — whether you enter them today or next year, and in either order. That makes the result fair to compare and fun to share.
Do other countries have their own compatibility traditions?
Yes. Beyond the FLAMES game of South Asia, China and other East-Asian cultures use the zodiac and bazi ("eight characters") birth-chart matching; Korea has gung-hap (궁합), a traditional marriage-compatibility reading; Japan has the popular belief in blood-type personality matching (ketsueki-gata); and Western pop culture leans on numerology and sun-sign astrology. All are cultural pastimes rather than science.
Sources & Methodology
The love percentage is computed client-side from a deterministic, order-independent hash of the two names (lowercase letters only), mapped to 0-100%. The FLAMES outcome follows the traditional rules: shared letters are cancelled one-for-one, the remaining letters are counted, and that count eliminates the F-L-A-M-E-S letters until one remains. This calculator is for entertainment and is not a measure of real-world compatibility.
