How the love percentage is calculated
This love calculator does not use random numbers. Instead it applies a deterministic hash function (DJB2) to the two names. The algorithm converts both names to lowercase, trims extra spaces, and sorts them alphabetically so that entering "Romeo" then "Juliet" gives the exact same score as "Juliet" then "Romeo".
The sorted pair is joined with an ampersand and fed through the hash. Each character code updates a running total: hash = hash * 33 + charCode. The final integer is reduced modulo 101 to produce a value from 0 to 100. Because the math is fixed, every unique pair of names always maps to one specific love percentage.
Score meanings for the love tester
A raw number is only half the fun. Here is how to read the result from this name love calculator:
| Range | Verdict |
|---|---|
| 0 to 20% | Better off as acquaintances |
| 21 to 40% | A slow start, needs patience |
| 41 to 60% | Friendly sparks, potential to grow |
| 61 to 80% | Strong connection, great match |
| 81 to 100% | Written in the stars |
These labels are part of the game. Real relationships depend on communication, shared values, and effort rather than a hash function.
Ideas for using this name love calculator
People use a love tester for all kinds of lighthearted scenarios. Try pairing characters from your favorite book or movie to see who scores highest. You can test celebrity couples, historical figures, or even pets.
At parties or sleepovers, the love calculator works well as an icebreaker. Write pairs on slips of paper, draw two at a time, and reveal the score. If you need more party tools, try the coin flip or dice roller for quick decisions, or the magic 8 ball when you want a mysterious answer instead of a percentage.
Why the same names always give the same score
Many online tools add hidden randomness so results change on every click. This tool intentionally avoids that. The DJB2 hash is a simple, well known string hashing method created by Daniel J. Bernstein. By sorting the names before hashing, order independence is guaranteed.
Determinism means you can share a result with a friend and they will see the identical number when they type the same two names. It also makes the tool predictable enough to be fair in games while still feeling surprising if you have not seen the score before.
Privacy and limitations
Because the calculation happens locally in JavaScript, no names are transmitted to any server. You can test any combination without worrying about data collection.
Keep in mind that this is purely entertainment. A love percentage generated from text characters has no scientific basis. For actual relationship questions, talk to the people involved rather than relying on a browser script. If you want other harmless generators, the yes or no wheel and random name picker follow the same privacy first approach.
Worked examples
Each result below was produced by the same code the tool runs, so you can check your own numbers against them.
| Example | Input | Result |
|---|---|---|
| Classic romance | First name: Romeo; Second name: Juliet | Pair: Romeo & Juliet; Love percentage: 51%; Verdict: Friendly sparks, potential to grow |
| Same name | First name: Alex; Second name: Alex | Pair: Alex & Alex; Love percentage: 86%; Verdict: Written in the stars |
| Pop culture | First name: Batman; Second name: Catwoman | Pair: Batman & Catwoman; Love percentage: 37%; Verdict: A slow start, needs patience |
| Long names | First name: Bartholomew; Second name: Seraphina | Pair: Bartholomew & Seraphina; Love percentage: 87%; Verdict: Written in the stars |
FAQ
Is this love calculator accurate?
It is a game, not a psychological assessment. The score comes from a mathematical hash of the letters in both names, so it is consistent but has no real predictive power about relationships.
Does the order of the names matter?
No. The tool sorts the two names alphabetically before calculating, so swapping their positions always returns the same love percentage.
Are my names stored or sent anywhere?
No. Everything runs in your browser. The names are processed by local JavaScript and never leave your device.
Can I use words instead of real names?
Yes. Any text works. You can test two cities, two foods, or any pair of words to see what score the algorithm produces.
Why do I get the same result every time?
The calculator uses a deterministic hash function rather than random numbers. Identical inputs always produce identical outputs so you can verify and share results reliably.
What is the highest possible score?
The maximum is 100 percent. The hash value is taken modulo 101, which yields integers from 0 to 100 inclusive.
