About this calculator
A love calculator is a light-hearted, entertainment-only toy that turns two names into a "compatibility" percentage. This version is fully deterministic: it lowercases both names, strips anything that is not a letter, sorts them so the order never matters, and runs the combined letters through a fixed hash to produce a number from 0 to 100. Because nothing is random, the same pair of names always produces exactly the same score, and swapping who is first makes no difference.
For example, “Alex” and “Sam” always return the identical percentage every time you check, and “Sam” and “Alex” give that same number — the tool then adds a playful verdict (from “a slow burn — friendship first” up to “a perfect pair”) based on which band the score falls in.
It has no scientific, psychological or predictive basis whatsoever — it is purely for fun. Enjoy it as an ice-breaker, a party game or a bit of harmless curiosity, not as relationship advice.
Frequently asked questions
How does the love calculator work?
It combines the two lowercased names, sorts them so order does not matter, and feeds the letters through a fixed mathematical hash to produce a number from 0 to 100. Because nothing is random, the same two names always return the same percentage.
Is the love calculator real or accurate?
Not at all — it is strictly for entertainment. There is no science behind matching compatibility to the letters in a name; treat the result as a bit of fun and nothing more.
Why do I always get the same score for the same names?
The score is computed from the letters alone with a deterministic formula, so it never changes between visits for a given pair of names, and swapping the order gives the same answer.
Does it matter whose name I enter first in the love calculator?
No — the calculator sorts the two names before hashing them, so “Alex and Sam” and “Sam and Alex” give exactly the same percentage. Order never changes the result.
What makes some name pairs score higher than others?
Nothing meaningful — the score comes purely from the letters running through a fixed formula, so it is essentially a fun coincidence of spelling. There is no pattern that reflects real compatibility, and a tiny change to a name can swing the number a lot.
Should I make any real decision based on the result?
Absolutely not — it is entertainment only, with zero predictive value. Treat a high or low score as a joke to share, never as a reason to pursue or avoid a relationship.
