The Love Calculator gives a fun, shareable love-match percentage from two names. Type your name and someone else’s, and it returns a number from 1 to 100 — purely for entertainment, and computed entirely in your browser.
How the score works
The percentage is a deterministic hash of the two names: both names are lowercased, trimmed, sorted (so order doesn’t matter), and run through a fast hashing function that maps the result to a value between 1 and 100. Because there is no randomness involved, the same pair always returns the same score — there is no way to reroll for a luckier number.
The names are sorted before hashing, so “Alex + Sam” and “Sam + Alex” produce exactly the same result. Only the letter content of the names matters; spacing differences (like “Alice Smith” vs. “alicesmith”) may produce different scores, so enter names consistently.
Just for fun
This is a playful tool, not a relationship test. Real compatibility comes from communication, shared values and time together — not from letters in a name. But it is a fun thing to screenshot and share with friends.
Everything is calculated locally in your browser, so the names you enter are never uploaded or stored.
Ideas for using it
- Group games — at a party or team event, enter pairs of names and see who gets the highest score. Works especially well when the names are drawn randomly from a hat.
- Social media sharing — the consistent result means two people can screenshot independently and get the same number, making it easy to verify and share together.
- Sibling and friendship pairs — works for any two names, not just romantic pairs. Friendship compatibility, sibling rivalry scores, or even fictional character pairs are all fair game.
- Pop culture pairings — try your favourite film couple, book characters, or celebrity pair. Because the result is deterministic, there is one canonical “score” for any famous pairing.
Why the score cannot be rerolled
Some love calculators use random number generators, which means you can keep clicking until you get a high score. This one does not. The deterministic hash means the score is fixed for any given pair of names — it is a property of those two names, not of the moment you clicked. That makes it shareable and verifiable: both people can check it independently and get the same answer.
If you want a different score for the same two people, the only way is to use a nickname or variant spelling — for example, “Mike” vs. “Michael” will produce a different result because the character content differs.
