How it works

Enter your name and your crush's name, and the calculator turns the pair into a percentage read on your chances. Both names get stripped of spaces, capitalization, and punctuation, then sorted into a fixed order and run through a formula that lands on the same number for the same two people every time, in either order, on any device. It's built the same way as the site's Love Calculator, just tuned to a different question, so the same two names won't score identically on both tools.

Like every calculator here, it runs entirely in your browser. Nothing about who you typed in gets saved or sent anywhere. The only thing that ever leaves your device is a share link, and only if you choose to generate one. Want your birthdays factored in too? The Crush Calculator by Name & DOB blends both into one score.

Where "will they like me back" quizzes came from

Long before anyone typed two names into a website, teenagers were doing the same math with a pencil. A folded note passed across a classroom with a circled "yes" or "no," or a margin doodle counting up shared letters in two names, was an early, low-tech version of the same question this calculator answers today. Teen magazines picked up the format in the 1990s, running quizzes with titles like "Does He Like You?" that scored a reader's answers into a verdict, no different in spirit from a percentage.

The internet version showed up in the early 2000s alongside the first wave of love-calculator sites, adapted to ask about a crush specifically rather than love in general. Where the classic love calculator borrowed the old FLAMES notebook game's letter-cancellation trick, crush calculators leaned harder into the "chances" framing familiar from those magazine quizzes: less about which relationship category you'd land in, more about a single number that felt like an answer.

That framing is why this page exists as its own tool rather than a slight variant of the Love Calculator above. A crush score answers "do they like me," a distinctly different question from "how compatible are we," even though the underlying math is a close cousin.

Signs your crush likes you back, not just a percentage

A number can't actually tell you whether someone likes you, but there are a few real behaviors worth paying attention to if you actually want to know. People who are interested tend to make time for you without being asked twice, remember small details you mentioned once in passing, and reach out first instead of only ever replying.

Body language matters too, though it's easy to over-read. Sustained eye contact, angling their body toward you in a group, and finding small reasons to be near you all say more than any single text message. None of these are guarantees on their own. Someone can be warm and friendly without romantic interest, and someone shy can like you a great deal while showing almost none of these signs. Taken together over time, though, they're a far more honest read than a hashed percentage ever will be.

What to do with your result

Treat a high score as permission to stop overthinking and actually talk to them, not as proof you don't need to. Treat a low score the way you'd treat a coin flip: a bit of fun, nothing to build a decision on. The number doesn't know anything about how you two actually get along, how often you talk, or whether they've mentioned you to their friends. Those are far better signals than a formula run on two names.

If you're stuck on whether to say something, our guide on how to confess to your crush walks through what to actually say and how to say it, without the guesswork a percentage can't resolve for you.

Just for fun. This runs on the same kind of fixed formula as the Love Calculator, just tuned to a different question, not a read on their actual feelings. The only way to really know is to ask them.

Frequently Asked Questions

How does the Crush Calculator decide the percentage?

It combines your name and your crush's name into one fixed score out of 100. The same two names always produce the same result, in any order.

Is a high (or low) score a real sign they like me?

No. It's a fun read, not a read on their actual feelings. The only way to know that is to ask them.

Can I share my result?

Yes. The share link encodes both names, so whoever opens it sees the same score you got.

Is this the same as the Love Calculator?

It uses the same idea but a different formula, so entering the same two names on the Love Calculator will give a different number.

Is there a version that also uses birthdays?

Yes. This page is name-only by design, kept quick and simple. For names blended with both birthdays, try the Crush Calculator by Name & DOB; for a pure date-of-birth read with no names at all, try the Birthday Compatibility Calculator.

Does it matter if I use a nickname instead of a full name?

It changes the result. The formula reads exactly what you type, so "Alexandra" and "Alex" score differently against the same second name. Use whichever version of the name you'd actually call them, and stick with it if you want to compare scores again later.
