Love Calculator

Enter two names and get your fun compatibility score.

For entertainment only — real compatibility takes more than names. 😉

How the Love Calculator Works

Enter two names and get a compatibility score between 0 and 100 %. Under the hood, the calculator combines both names and runs them through a deterministic hash function — a bit of math that turns text into a number. The same two names therefore always produce the same score, no matter when or where you try. Swap in a nickname, though, and the universe may have a different opinion.

The History of Love Testers

Name-based love tests are older than the web: schoolkids have played pencil-and-paper versions like "FLAMES" for generations, and arcade "love tester" machines date back to the 1920s. The digital version simply replaced the pencil with a hash function — the fun stayed the same.

What Actually Predicts Compatibility

Since you asked (or even if you didn't): relationship research points to things like communication style, shared values, humor, and how couples handle conflict — the psychologist John Gottman famously predicts relationship outcomes from how partners argue, not whether they do. None of that fits in a name, which is exactly why this calculator lives in our Fun category.

Share the Fun

Scores make great conversation starters. Screenshot your result, compare with friends, test your celebrity crush — and remember that a 23 % has never stopped a great love story, nor has a 98 % guaranteed one.

Frequently Asked Questions

Is the love calculator scientifically accurate?
No — it is pure entertainment. The score comes from a hash of the two names and says nothing about real compatibility. Enjoy it as a game.
Why do the same names always give the same score?
The calculator uses a deterministic algorithm: identical input, identical output. That consistency is intentional — it makes comparing scores with friends more fun.
Do first and last names change the result?
Yes — any change to the text changes the hash. "Anna & Tom" scores differently than "Anna Miller & Tom Smith". Pick one convention when comparing.
Is my data stored anywhere?
No. The calculation happens entirely in your browser; names are never sent to a server.
