Love Calculator
Type in two names and our love calculator gives you a playful compatibility score out of 100 — the same silly, sweet game you played on paper in school, now instant and shareable.
It is just for fun, of course. Real love is not decided by letters lining up. So once you have your score, do the thing that actually moves someone: write them a letter that says what the number never could.
How it works
Type both names
First names are enough. Nicknames and spellings change the result, so pick one version of each name and stay with it if you want a score you can compare later.
Read the score
You get a percentage and a short line describing it. There is no randomness involved, so refreshing the page will not improve your number — which is most of the fun.
Send it, then say something real
Screenshot it for the laugh. Then follow it with one sentence that is actually about them, because the number on its own tells the other person nothing.
What a love calculator can and cannot tell you
A name-based compatibility score is a game, and it is worth being straightforward about that: the letters in two names carry no information about whether two people are good for each other. What the calculator does reliably is produce the same score for the same pair every time, which is what makes it shareable — you and your friend get the same number, so there is something to argue about.
The reason these have survived since the paper-and-pencil playground version is not that anyone believes them. It is that they give you permission to raise the subject. Typing two names into a box is a much lower-stakes way of asking "are we a thing?" than asking directly, which is precisely why it has outlived every more sophisticated version of the idea.
Why the same names always give the same score
The calculation is deterministic. Every letter in the two names is converted to a number, the numbers are combined in a fixed way, and the result is reduced to a value between 0 and 100. Nothing is random and nothing is stored, so the same pair of names typed on a different day, on a different phone, by a different person returns exactly the same figure.
That is the property that makes it worth playing with. A random number would be meaningless the moment two people compared results; a stable one behaves like a fact you can send to someone. It also means the score is sensitive to spelling in ways people find funny — the full name and the shortened one give different results, as do a maiden name and a married one. None of it means anything, and everyone knows it, which is why nobody minds.
What actually predicts compatibility
The research on relationship stability is fairly consistent, and none of it involves names. The strongest predictors are how couples handle disagreement — whether criticism stays about the behaviour rather than the person, whether either party withdraws entirely — plus shared expectations about the practical shape of a life, and the ratio of positive to negative interactions in ordinary time rather than during conflict.
None of this is as fun as a number out of 100. But if the score sent you looking for something more substantial, the honest version of the exercise is a conversation about what you each expect, and our couples questions are built to start exactly that.
What to do with a high score
Screenshot it, send it, enjoy the two minutes. Then, if the number happened to land on something real, say the real thing. A score is a prompt, not a message — the person on the other end of it learns nothing about how you feel from a percentage.
A short letter naming two or three specific things you have noticed about them does what the number is standing in for. It takes about ten minutes, it costs nothing, and unlike a screenshot it is still there in a year.
A score is a bit of fun. A letter is the real thing.

Questions people ask
How does the love calculator work?
It turns the letters of both names into a stable score between 0 and 100, so the same two names always give the same result. It is a light-hearted game, not a real prediction — think of it as a fun conversation starter, not relationship advice.
Is the love calculator free?
Completely free, with no account and no sign-up. Nothing you type is saved or sent anywhere — the score is worked out right in your browser.
What should I do after I get my score?
Screenshot it for a laugh, then say the real thing. The best follow-up to a 99% score is an actual love letter — you can write and send one free on ShareLove in a couple of minutes.
Should I use nicknames or full names?
Either works, but they give different results, because the calculation reads exactly the letters you type. Katie and Katherine are two separate inputs. If you want a score you can compare with a friend later, agree on one version of each name first.
Is a love calculator accurate?
No, and it is not trying to be. It knows nothing about either person beyond the letters in their names, so it cannot say anything about a real relationship. The only thing it is reliably accurate about is itself — the same two names always return the same number.
