The love calculator gives you a fun, name-based compatibility percentage between any two people. Enter both names and hit Calculate — the result is a tongue-in-cheek compatibility score with a playful verdict. It is completely deterministic: the same two names will always produce the same score, so you can test different combinations and compare results. Is this scientifically accurate? Absolutely not — and that is entirely the point. Real compatibility is built on communication, shared values, emotional maturity, and trust. No algorithm can measure chemistry, patience, or whether you both agree on the thermostat setting. This calculator is pure fun: the kind of thing to try at a party, share with friends, or use to settle the question of which celebrity pairing is most "compatible." The algorithm uses a deterministic hash of both names, mapping to a score between 1 and 100. The order of names does not matter — Romeo + Juliet will score the same as Juliet + Romeo. Use it for entertainment, share the result, and remember that the best relationships are built on a lot more than name-hash mathematics.

How It Works
Entertainment only. Hash(name1 + name2) mapped to 1–100. Same names = same score always.
The calculator uses a deterministic character-based hash of the two names combined. Both names are joined, converted to lowercase, and non-alphabetical characters are stripped. A rolling hash multiplies each character's position value and accumulates through the string. The result is mapped to a 1–100 scale. The same input always produces the same output — there is no randomness. This means it works as a fun "oracle" that friends can independently verify: if you tell someone your score, they can enter the same names and get the same result. Score tiers: 90–100%: Perfect match — the stars aligned. 75–89%: Great chemistry. 60–74%: Pretty good odds. 40–59%: It's complicated. 20–39%: Opposites attract, maybe. 1–19%: A challenging match — but hey, it's just for fun!
Frequently Asked Questions
Is the love calculator accurate?
No — and proudly so. This is a pure entertainment tool based on a mathematical hash of names. Real romantic compatibility involves communication, shared values, emotional intelligence, attraction, and a thousand other factors that no name-based algorithm can measure. Use it for fun, share it with friends, and take the score with the grain of salt it absolutely deserves.
Why do the same names always give the same score?
The algorithm is deterministic — it uses a fixed mathematical hash rather than random numbers. This is intentional: it means your score is "stable" and friends can verify it independently. The consistent result is part of the fun — Romeo and Juliet will always get the same score regardless of when or where you test it.
Does the order of names matter?
The two names are combined before hashing, so swapping order (Name A + Name B vs Name B + Name A) produces a slightly different combined string and may give a different score. For a "definitive" result, agree on a consistent order — typically first-name + first-name of the people in question.
What makes two people actually compatible?
Real compatibility research points to: shared values and life goals, complementary communication styles, mutual respect, similar approaches to conflict resolution, compatible views on money and lifestyle, and physical and emotional attraction. Relationship psychologist John Gottman's research highlights contempt as the single biggest predictor of relationship failure — far more important than any compatibility score. Genuine connection is built through time, effort, and showing up for each other.
Is the love calculator free?
Yes — completely free, no sign-up needed, and no data is stored. Enter any two names, get your entertainment compatibility score, share it with friends, and remember: the algorithm knows nothing about how either of you makes a cup of tea. Real love is in the details.
