Love Calculator — A love calculator is an entertainment tool that turns two names into a playful compatibility score and relationship message.
Enter Names: Enter first person's name and second person's name.
Click Calculate: Click the calculate button to see your match.
Get Results: See the compatibility percentage and message, then share it if you like.
Couples: A playful test for dating, long-term, or married pairs.
Crushes: A low-stakes ice-breaker or conversation starter.
Friends: Compare scores across a friend group at a party.
Entertainment: Test celebrity couples, fictional characters, or random pairings for social posts.
A love calculator takes two names and returns a compatibility percentage between 0 and 100. It belongs to the same family of games as FLAMES and MASH — fun to play, easy to share, and completely unscientific. There is no research showing that the letters in two people's names predict anything about how well they get along.
That honesty is worth stating up front, because the tool is genuinely fun when you treat it that way: as an ice-breaker with a crush, a party game with friends, or a quick laugh testing celebrity couples. What it can't do is tell you whether a real relationship will work — that depends on how two people actually treat each other, not on their names.
The algorithm is deterministic: the same two names always produce the same percentage. In broad strokes, it works like this:
There is no standard formula. Each site picks its own arbitrary math — some count occurrences of the letters in the word "LOVE", some use numerology-style digit reduction, some just hash the names. Enter the same couple on five different sites and you'll get five different percentages, which is itself a good reminder that the number is arbitrary.
Small input changes matter, too: "Katherine + Sam" and "Katie + Sam" will usually score differently, because the letters are different. If your score disappoints, try a nickname — that's the level of seriousness this deserves.
The result comes with a label based on where it lands:
| Percentage | Label | Vibe |
|---|---|---|
| 91% - 100% | Perfect Match | Soulmate territory — screenshot-worthy. |
| 61% - 90% | Great Match | Strong connection, solid bragging rights. |
| 31% - 60% | Moderate Match | Room to grow — or to retest with nicknames. |
| 0% - 30% | Challenging Match | Opposites attract, allegedly. |
Name-based matchmaking games are much older than the internet. Schoolyards around the world have played FLAMES for generations: cross out the letters the two names share, count what's left, and cycle through F-L-A-M-E-S (Friends, Lovers, Affectionate, Marriage, Enemies, Siblings) to land on a prediction. American sleepovers had MASH (Mansion, Apartment, Shack, House). Further back, numerology traditions like Gematria assigned numbers to letters and read meaning into the sums — the same letter-to-number trick modern compatibility games still use.
Online versions took off in the early 2000s and have stayed popular for the same reason the paper games did: they give two people an excuse to talk about whether they'd be a good match. The pencil-and-paper math just moved into the browser.
Since we've been clear the score is a game, here's the real answer. Decades of relationship research — most famously by the Gottman Institute — point to factors that have nothing to do with names:
If a percentage on a screen prompts a fun conversation about any of that, it has done more for your relationship than the number ever could.
Everything runs client-side in JavaScript. The names you enter are never sent to a server, never logged, and never stored — close the tab and they're gone. There's no account, no tracking of your inputs, and no database of who tested whom. Test your crush's name with confidence; nobody will know but you.
