How a Name Love Calculator Works
Why Alice and Bob score differently from Bob and Alice, and what that reveals about the game.

What the name calculator actually calculates
Our Love Calculator by Name calculates a repeatable number from two ordered text inputs. It uses a hash and a remainder rule, rather than counting matching letters or evaluating a couple. This guide follows the arithmetic so you can see why spelling and order matter without assigning meaning to the percentage.
The formula explained
The calculation follows these steps:
- Remove spaces at the beginning and end of each name.
- Lowercase English A–Z letters. Other letter cases are not converted by this method.
- Join the first name, a pipe character (
|), and the second name, preserving their order. - Calculate an MD5 hash of that text and convert its first eight hexadecimal characters to a decimal number.
- Take the remainder after dividing that number by 51, then add 50.
The result is between 50% and 100%. This range is a design choice in the game. MD5 is used to generate a number, not to protect private information.
A name compatibility example
Enter Alice first and Bob second and the result is 66%. Swap them and it becomes 76%. The people have not changed; the ordered text has. This is why the result should never be read as how much one person loves the other.
To follow the arithmetic, the normalized text for the first pair is alice|bob. Its MD5 hash starts with bb6b9652. Those eight hexadecimal characters represent 3,144,390,226 in decimal. Dividing that number by 51 leaves a remainder of 16, so the final score is 50 + 16 = 66%. The calculation does not count shared letters or look up facts about either person.
Entering ALICE and bob keeps the first result because English capital letters are lowercased. Adding spaces at the beginning or end of either name also leaves it unchanged. Adding a middle name changes the input and may change the score.
A second example: order and identical names
Maya followed by Noah gives 65%; Noah followed by Maya gives 90%. These are outputs of the same rule with the text reversed. The larger result does not indicate that Maya's or Noah's affection changed.
Identical names do not trigger a special perfect-match result: Alex followed by Alex gives 58%. The rule has no knowledge of whether two people share a name, are friends, are dating, or have ever met.
Why a result changes
Spelling, punctuation, internal spaces, and name order can change the hash. Alex and Alexander are different inputs. Reversing the names may change the result too. The original PHP lowercasing behavior does not convert every accented uppercase letter.
You can use nicknames instead of legal names. More identifying detail does not make the result more accurate.
Can different pairs have the same percentage?
Yes. There are only 51 possible whole-number outputs, from 50 through 100, while there are far more possible name pairs. A repeated score is expected in a game with that limited output range. It does not show a hidden connection between the pairs.
The range alone does not tell you how often a particular score appears across real names. We have not measured score rarity or published a representative name dataset, so a result should not be labeled unusually lucky or statistically special.
Why two love calculators can disagree
There is no universal formula for turning names into a love percentage. Another website may use letter counts, a different hash, or different score ranges. A higher number elsewhere does not mean it found a better measure of your connection.
The same distinction applies to our birthday compatibility formula: a rule can be predictable without predicting a relationship. Our tools disclose their methods so you can understand the result rather than guess what is behind it.
A better conversation
Treat the percentage as an icebreaker. Ask what you appreciate about one another or what a good shared afternoon looks like. A score cannot establish trust or respect.
For reflection based on your own choices, try the free love language test. It counts your selected answers instead of generating a relationship prediction.
Common questions
Does 100% mean we are soulmates?
No. It means the formula produced its highest possible value for those inputs. It does not evaluate either person's feelings, values, behavior, or plans.
Should I keep changing the names until the score improves?
You can experiment as part of the game, but you are changing the input, not learning more about the relationship. If a result worries you, set the number aside and pay attention to what the other person actually says and does.
