Love Compatibility Calculator
Type two names and get a playful compatibility percentage. It is a bit of fun for parties and icebreakers — the number comes from the letters in the names, nothing more.
Calculation inputs
Enter any two names. The same two names always give the same score.

For entertainment purposes only. This score is generated by counting letters in two names — it is not scientific, not meaningful, and says nothing about any real relationship.
About this calculator
This is a lighthearted novelty tool: type two names and it produces a compatibility percentage using the classic playground letter-counting game. It is for entertainment only — the number comes purely from the letters in the names and says nothing about any real relationship.
How the calculation works
- Count how many times the letters L, O, V, E, S appear across both names
- Repeatedly add neighbouring counts (keeping the last digit) until two digits remain
- Those two digits form the percentage
Notes and assumptions
This is the classic playground letter-counting game, sometimes called the “loves” match. It is deterministic: the letters decide the score, so it can never measure anything about real people.
Real compatibility depends on communication, values, and effort — no name algorithm can tell you anything meaningful about a relationship.
How it works in plain English
The tool uses the old 'loves' letter game. It counts how many times the letters L, O, V, E, and S appear across both names combined, ignoring spaces, punctuation, and capital letters.
Those five counts are then collapsed by repeatedly adding neighbouring numbers together, keeping only the last digit each time, until two digits remain. Those two digits form the percentage.
Because the algorithm is fixed, the same two names always produce the same score — which is exactly why it cannot measure anything real. Compatibility between people depends on communication, shared values, and effort, none of which appear in the spelling of a name.
The formula
- Count letters L, O, V, E, S across both names
- Repeatedly add neighbouring counts (keep last digit) until two digits remain
- The two digits form the percentage
Worked example
Suppose you enter Alex and Jordan.
Across the two names, the letters L, O, V, E, S appear 1, 1, 0, 1, 0 times respectively. Adding neighbours gives 2, 1, 1, 1, then 3, 2, 2, then 5, 4.
The final two digits are 5 and 4, so Alex and Jordan score 54% — a fixed result that will be identical every time those two names are entered.
Frequently asked questions
Is this compatibility score scientifically meaningful?
No, not in any way. The score is produced by counting letters in two names. It cannot measure personality, values, communication, or anything else that determines whether two people are compatible. Treat it as a party game, nothing more.
Why do the same two names always get the same score?
The algorithm is deterministic: it counts letters and adds them in a fixed pattern, with no randomness. Identical input always produces identical output. That predictability is itself proof the number reflects spelling, not people.
Does it matter whether I use full names or nicknames?
It changes the score, because different letters are counted — which shows how arbitrary the result is. 'Elizabeth' and 'Liz' will produce different percentages with the same partner. Use whichever spelling is more fun; neither means anything.
Where does this game come from?
It is a version of the classic schoolyard 'loves' or FLAMES letter-counting games that have circulated for generations. Children would count shared letters in two names to 'predict' romance. This tool simply automates that playground ritual.
Should I make any real decision based on this score?
Absolutely not. The score is entertainment only and contains zero information about a real relationship. Decisions about people deserve conversation, honesty, and time — never the output of a letter-counting game.
