About the Love Calculator
This is a light-hearted compatibility toy. Enter two names and it returns a percentage, a short label such as "Great match", a progress bar, and a one-line comment. The score is recalculated as you type, and the button simply forces a fresh result.
It is designed for parties, group chats, Valentine's posts, and anyone who wants a harmless conversation starter. It is not a relationship assessment and makes no claim to predict anything about two people.
How to use it
- Type the first name, up to 40 characters.
- Type the second name.
- Press Check compatibility, or keep typing: the result refreshes once both fields are filled.
- Read the percentage and label; the meter fills to match the score.
How the number is produced
The tool lowercases both names, sorts them alphabetically, joins them, and adds each character's code multiplied by its position plus three. That total is divided by 101 and the remainder becomes the score. Because the names are sorted, Alex + Sam and Sam + Alex produce identical results. If both names are the same, the score is raised to at least 88. For Alex and Sam the raw total is 4510, which leaves 66 after division, so the result is 66% and "Good potential".
Limitations and privacy
The score is a deterministic checksum, not randomness, astrology, or psychology. The same pair always gives the same percentage on any device, which is why it can feel eerily consistent. Case is ignored and accents are not normalised, so the same name spelled with and without an accent counts as two different inputs. Nothing is stored or sent to a server; the names stay in the page and disappear on reload. Treat the output as entertainment, since real compatibility depends on communication, trust, and effort.
Frequently asked questions
Why did I get the same score twice?
Because the calculation is a fixed formula over the letters. Identical input always produces identical output; there is no random seed.
Does the order of names matter?
No. The names are sorted before the score is calculated, so swapping them changes nothing.
Can I enter nicknames or full names?
Yes, any text up to 40 characters works. Different spellings count as different names and give different scores.
