Just for fun. This is an entertainment toy, not relationship advice. The same two names always give the same score, in any order.
Curious how two names stack up? This love calculator turns any pair of names into a playful compatibility score from 0 to 100 percent, shown inside a heart with a cheeky verdict. It is fast, private, and runs entirely in your browser, and you can copy a shareable result line in one tap.
What is the Love Calculator?
A love calculator is a lighthearted game that takes two names and hands back a single compatibility percentage. People have played name-matching games for generations, from the old FLAMES paper game to the love testers you find in arcades, and this tool keeps that same spirit. It is built for giggles with a crush, an icebreaker at a party, or a quick distraction, not for making real decisions about your relationships.
The score you see is deterministic, which is a fancy way of saying the math is fixed rather than random. The two names are cleaned to letters only, sorted alphabetically so order never matters, joined together, and run through a stable hash that always lands on the same number for the same pair. That is why Alex and Jordan returns the exact same percentage as Jordan and Alex, and why retyping the same names tomorrow gives you the identical result. There is no luck, no server, and no hidden dice roll.
It is worth being honest about what the number means: nothing, really. Real compatibility grows from shared values, communication, trust, and time together, none of which can be captured by spelling. Two people with a low score can be wonderfully happy, and a high score guarantees nothing. Treat the percentage as a fun talking point, laugh at it, screenshot it, and move on.
Because everything happens in your browser, the names you type are never sent anywhere or stored. You can match as many pairs as you like, copy the result to share in a chat, and refresh the page to clear it all. That makes it safe to play with friends without worrying about privacy.
When to use it
- Breaking the ice at a party or on a first date with a silly compatibility score.

Formula & method
Worked examples
You match the default names, Alex and Jordan, and want to confirm order does not matter.
- Clean the names to letters only: "alex" and "jordan".
- Sort them alphabetically: "alex" comes before "jordan".
- Join into one string: "alexjordan".
- Hash each character with h = (h times 31 plus charCode) as an unsigned 32-bit value, then take h modulo 101.
- Swapping to Jordan and Alex sorts to the same "alexjordan", so the score is identical.
Result: Both Alex + Jordan and Jordan + Alex return the very same percentage.
You test a name written two ways, "Mary-Jane" and "mary jane", to see if punctuation matters.
- Strip non-letters from "Mary-Jane": the hyphen is removed, leaving "maryjane".
- Strip non-letters from "mary jane": the space is removed, leaving "maryjane".
- Both cleaned forms are identical, so they sort and join the same way.
- The hash runs over the same letters in the same order.
Result: Spelling the name with a hyphen, a space, or different capitals gives the same match score.
What each score band means in this love calculator
| Score range | Verdict shown | How to read it |
|---|---|---|
| 90 to 100 | A perfect match | The playful top tier, screenshot it and brag |
| 70 to 89 | Great chemistry | A strong, fun result to share |
| 50 to 69 | Worth a try | A solid middle ground worth a laugh |
| 30 to 49 | It will take some work | A cheeky nudge, not a verdict |
| 0 to 29 | Opposites attract, maybe | Low score, plenty of room for a comeback joke |
How names are cleaned before scoring
| You type | Cleaned to | Why |
|---|---|---|
| Alex | alex | Lowercased for consistency |
| Mary-Jane | maryjane | Hyphen removed, letters only |
| Jose 23 | jose | Digits and spaces stripped out |
| O'Brien | obrien | Apostrophe removed |
Common mistakes to avoid
- Believing the percentage is real compatibility. The score is a fixed bit of math based only on spelling. It says nothing about whether two people are actually a good match. Real compatibility comes from values, communication, and time, never from letters in a name.
- Expecting a different result on each try. This calculator is deterministic, not random. The same two names always return the same number, so refreshing or retyping will not magically improve your score.
- Thinking the order of names changes the outcome. The two names are sorted before scoring, so Alex and Jordan gives the same result as Jordan and Alex. Swapping the boxes never changes anything.
- Adding nicknames or emoji to nudge the score. Anything that is not a letter a to z is stripped out before the math runs. Numbers, spaces, hyphens, and emoji are ignored, so they cannot be used to game the result.
Glossary
- Compatibility percentage
- The 0 to 100 number this tool returns for a pair of names. It is for fun only and has no real meaning.
- Deterministic
- A process that always produces the same output for the same input, with no randomness involved.
- Symmetric
- A result that does not depend on order, so swapping the two names leaves the score unchanged.
- Hash
- A function that turns text into a number by combining each character, used here to map a name pair to a score.
- Character code
- The numeric value a computer uses for a letter, for example the code for the letter a, fed into the hash.
- Modulo
- The remainder after division. Taking the hash modulo 101 keeps the final score between 0 and 100.
Frequently asked questions
How does the love calculator work?
It cleans both names to letters only, sorts them alphabetically, joins them, and runs a fixed rolling hash over the characters. The hash is reduced with modulo 101 to give a whole number from 0 to 100. The same names always produce the same score.
Is the love calculator accurate or scientific?
No. It is purely for entertainment. The number is generated by simple math on the spelling of two names and has no connection to real relationship compatibility, which depends on values, trust, and communication.
Why do I get the same result every time?
The tool is deterministic, meaning the math is fixed rather than random. For a given pair of names it will always land on the same percentage, whether you check now or a week from now.
Does the order of the names matter?
No. The two names are sorted alphabetically before scoring, so Alex and Jordan returns exactly the same percentage as Jordan and Alex. The result is symmetric.
Do hyphens, spaces, or capital letters change the score?
No. Before scoring, names are lowercased and every character that is not a letter is removed. So "Mary-Jane", "mary jane", and "MaryJane" all clean to the same letters and score the same.
Are the names I type saved or sent anywhere?
No. Everything runs locally in your browser. The names are never uploaded or stored, and refreshing the page clears them completely.
