Can two names really tell you if a couple is meant to be? No, and this page says so plainly. The Love Calculator turns two names into a percentage and a short verdict, purely for fun.
It suits friends, couples, and party games. Type two names, press one button, and compare scores with someone else. Nothing here has a scientific basis, and it cannot predict how a real relationship will go.

What the Calculator Does
The tool has two text boxes and one button. It gives back two results, and a short for-fun note sits above the button.
- First Person Name and Second Person Name: the two names you want to compare.
- Calculate Compatibility: a button that runs the math again. Results also update as you type.
- Love Compatibility Index: a whole-number percentage from 50% to 100%.
- Match Verdict: a short label with an emoji, such as Good Match or Great Harmony.
There is no copy button, no saved history, and no longer reading. You see one score and one label.
How to Use It, Step by Step
- Type a name into First Person Name. The sample value is Romeo.
- Type a name into Second Person Name. The sample value is Juliet.
- Watch the result card update as you type. Pressing Calculate Compatibility gives the same answer.
- Read the Love Compatibility Index and the Match Verdict in the result card.
- Change a spelling to see how the score moves.
If either box is blank, the result cards show N/A and a red message says to enter both names. A name with no letters from A to Z gets a similar message.
How the Score Is Made
The score is not a measure of anything about two people. The tool cleans each name, sorts the two names alphabetically, and joins them around the word "love".
Then it runs a simple scramble over every letter. The final number is mapped onto the range 50 to 100.
Sorted Name A + love + Sorted Name B→Letter Scramble (Hash)→50 + (Hash mod 51)=Score %
- Clean each name: lowercase it, simplify accents, and keep only the letters a to z.
- Sort the two cleaned names alphabetically, so the entry order is lost.
- Start with a hash of 0.
- For each letter, set hash = (hash × 31 + the letter's character code) mod 10,000.
- Score = 50 + (final hash mod 51), so it is always between 50 and 100.
- Verdict: 90 or more is Soulmates. 75 to 89 is Great Harmony. 60 to 74 is Promising Spark. Below 60 is Good Match.
No randomness is involved. The same two names always give the same score.
Worked Examples
These numbers come from running the tool's exact steps on each pair of names.
| Names Entered | Joined Text | Final Hash | Score | Verdict |
|---|
| Romeo and Juliet (either order) | julietloveromeo | 2,097 | 56% | Good Match |
| Ana and Ben (either order) | analoveben | 7,461 | 65% | Promising Spark |
| Sam and Alex (either order) | alexlovesam | 6,335 | 61% | Promising Spark |
| Ana and Anna (either order) | analoveanna | 246 | 92% | Soulmates |
For Romeo and Juliet, 2,097 divided by 51 leaves a remainder of 6. Adding 50 gives 56%, which is the sample result on the page. Adding one letter to Ana makes Anna, and the score jumps from 65% to 92%.
How to Read the Results
Love Compatibility Index is only a number produced by the letter scramble. A 92% does not mean a couple will do well. A 56% does not mean they will struggle.
Match Verdict is a label picked from the score alone. It adds nothing new. Treat it as a joke line you can share with friends.
Name Order, Spelling, and Accents
Because the tool scrambles letters in sequence, small spelling changes shift the score a lot. Swapping the two names changes nothing, since the cleaned names are sorted before scoring. Capital letters do not matter either, so ROMEO and romeo give the same score.
Accented letters are simplified to plain ones. So José and María score 60%, the same as Jose and Maria. Spaces, digits, and hyphens are ignored. Special letters such as ß and ø are mapped to ss and o.

Limitations and Assumptions
- This is entertainment only. The score has no scientific basis and does not measure compatibility.
- The scale is not neutral. The lowest verdict label is Good Match, so every pair looks decent.
- The result is fixed by the spelling of the names, not by feelings, habits, or values.
- Only the letters a to z are used. Names written only in other alphabets, such as Arabic or Chinese, show N/A and a message.
- Each name box holds up to 60 characters.
FAQs About the Love Calculator
Is the Love Calculator accurate?
No. It has no scientific basis. The percentage comes from a letter scramble, not from any real measure of love or compatibility.
Does the tool save or share the names I type?
It has no save, copy, or share button. The score is worked out on the page from the two names in the boxes.
Why is the lowest score 50%?
The formula adds 50 to a number between 0 and 50. That means every pair lands between 50% and 100%. It is a design choice, not a finding.
Should I use full names or first names?
Either works. A longer name feeds more letters into the scramble and gives a different score. Pick one style and stay with it if you want to compare results.
Can I use this to decide if a relationship will last?
Please do not. Real relationships depend on trust, communication, and shared goals. A name score cannot tell you any of that.
