Love Calculator
Enter two names for an instant, just-for-fun compatibility score — the same pair always gives the same result.
Completely FREE Love Calculator. No signup, no email, no credit card. Instant results, no catch. Type two names and get an instant love-compatibility score worked out from the letters — no birthdays, no personal data, nothing sent anywhere. Same pair of names always gives the same result.
The score breaks down into four playful factors — shared letters, name-length harmony, vowel balance, and rhythm resonance — shown as animated bars so you can see exactly where the points came from. It runs entirely in your browser and disappears the moment you refresh.

How the score is worked out
The calculator takes both names, strips them down to their letters, converts everything to lowercase, and combines them into a single signature. That signature is fed through a short deterministic hash — a fixed mathematical recipe that always produces the same number for the same input. The result is mapped to a 0–100 scale and displayed as your compatibility score.
Because the algorithm sorts the two names before combining them, the order you enter them in makes no difference: "Alice & Bob" and "Bob & Alice" will always produce the same score. Nothing random is involved — the only thing the score depends on is which letters appear in each name.
The four compatibility factors
Shared letters. How many distinct letters appear in both names, measured as a fraction of all the distinct letters across both names combined. Two names that share most of their letters score higher here. This factor is symmetric by definition — the set of shared letters is the same regardless of which name you put first.
Name-length harmony. How close the two names are in length. Names with similar numbers of letters score higher. The idea is a loose proxy for rhythm — two names that are roughly the same length tend to flow together in the same breath.
Vowel balance. The fraction of vowels in each name, compared. Names with similar vowel densities score higher. Vowel density shapes how open or closed a name sounds, so similar densities suggest a similar sonic texture.
Rhythm resonance. A fourth score derived from the combined letter signature of the pair using a secondary hash pass. It gives each pairing something uniquely theirs — two couples who score identically on the first three factors will still differ here. It's the "secret ingredient."
Is it accurate? No — and that's the point
The love calculator is a game. It knows nothing about your personalities, histories, values, or chemistry — just the letters in two names. A score of 97% does not mean you should propose; a score of 12% does not mean you should flee. What the calculator does do reliably is give the same answer every time you ask, which makes it a satisfying kind of fun: you can debate the result, try nicknames against full names, and compare notes with friends, knowing the numbers are stable.
Think of it as a conversation starter dressed up in maths. The algorithm is transparent and consistent; the rest is up to you.
Tips for getting interesting results
Try your full first name against a nickname — you may get a surprisingly different score. Compare the same pair of names spelled differently (e.g., "Sara" vs. "Sarah"). Try a celebrity couple or a fictional pair you love. The score is deterministic, so there is no point retrying the same inputs hoping for a better number — but switching from a nickname to a middle name or a surname is fair game and will give you a genuine second data point.
Privacy
The names you type never leave your device. The entire calculation happens inside your browser using JavaScript — there is no server call, no analytics on the inputs, and no storage of any kind. Closing or refreshing the page removes everything. You could enter real names or invented ones and the result is equally private either way.
Frequently asked questions
Is it really free? Completely. No account, no email, no credit card, no paywall. Enter two names and your full result appears immediately.
Why does the same pair always get the same score? The algorithm is deterministic — it uses a fixed hash function with no randomness. Same letters in, same number out, every time. This is intentional: the score is meant to feel stable and "official," even though it's just for fun.
Does the order of names matter? No. The calculator sorts the two names internally before computing, so "Alex and Sam" and "Sam and Alex" produce identical results.
Can I use full names, nicknames, or surnames? Any combination. The calculator only looks at the letters themselves, so "Liz" and "Elizabeth" will give different scores because they have different letters. That makes it worth experimenting with different forms of a name.
What do the four factor bars mean? They show the sub-scores that feed the overall result — shared letters between the names, how similar the name lengths are, how close the vowel densities are, and a rhythm score unique to the pair. They're illustrative breakdowns, not separate predictions.
My score is low — should I be worried? Absolutely not. The score reflects the letters in two names, which have no bearing on real-world attraction, affection, or compatibility. Plenty of real couples have names with almost nothing in common. Take it lightly.
Important
This love calculator is a lighthearted game, not a real measure of compatibility, attraction, or relationship success. The score is generated from the letters in the names for fun only — please don't make any real decisions based on it.
