How to Do the Love Calculator on Paper (TRUE LOVE Method)

What is the paper love calculator?

The paper love calculator is the playground version of the love calculator: two names, a pen, the words TRUE and LOVE, and a percentage at the end. It is a Game, which is this site's label for a fixed formula on letters. You count letters and nothing else, so the same two names always give the same number, in whichever order you write them. It is one of the ways people check love compatibility, and it is the oldest one on this site.

This page covers one part of the love calculator. Start with the love calculator if you have not played it yet, because the tool on the home page runs the same six steps.

How do you do the love calculator on paper?

Six steps, about two minutes, and nothing but a pen. Here are the step-by-step instructions, and they work on any two names.

Write the two names down, letters only. Drop spaces, hyphens and apostrophes, and write an accented letter as its plain letter, so Jose and José count the same. Capitals make the counting easier.
Write TRUE across the top of the page: T, R, U, E. Under each letter, write how many times that letter appears in the two names together.
Add those four numbers. If the total has two digits, add the digits together until one digit is left: 17 becomes 1 plus 7, which is 8. That single digit is the TRUE number.
Do the same for LOVE: L, O, V, E. Count each letter across both names, add the four numbers, and reduce to one digit. The E is counted here again, because each word is counted on its own.
Write the TRUE number, then the LOVE number, side by side. Two digits.
Read those two digits as a percentage. That is your score.

Here is the same rule run on a pair of fictional names, so you can check your own working against it.

Romeo and Juliet are fictional. Joined and normalised the names are ROMEOJULIET. Count each letter of TRUE in those letters and add the counts, do the same for LOVE, and set the two totals side by side.

T	R	U	E	Total
1	1	1	2	5

L	O	V	E	Total
1	2	0	2	5

TRUE gives 5 and LOVE gives 5, which reads as 55%, band: Could go either way. Formula version 2.0. Two single digits side by side can never read 100, so the highest Love Score is 99.

The score runs from 0 to 99 and never reaches 100. The FAQ below says why.

Is love percentage on paper the same as the love calculator on paper?

Yes. They are two names for one game. The game produces a love percentage, so people name it after the output on some days and after the input on others. The same six steps are searched for as the love calculator on paper, the love test on paper, the love tester on paper and how to do love percentage on paper. This page answers all of them. None of those names changes a single count.

One paper game travels under several names. One other paper game is genuinely different.

How does the LOVES paper game differ from TRUE LOVE?

It is a different game. In LOVES you count L, O, V, E and S across the two names and write the counts in a row. Then you keep adding the numbers that sit next to each other, splitting any two-digit sum, until two numbers are left. The five letters of LOVES are the whole phrase, where TRUE LOVE uses eight.

A 2016 mathematics paper by Iain Johnston studied that adding rule and showed it does not always finish. That is why a long pair of names can run for line after line on paper without settling. TRUE LOVE always finishes, because every digit-sum step makes the number smaller. Our own calculator runs the TRUE LOVE rule, not the LOVES one.

Why does the paper result differ from the online love calculator?

It should not. When a paper answer and a screen answer disagree, the difference is almost always in the counting rather than in the rule. Three things account for nearly all of it.

A different tool is running a different formula. Most sites never say which algorithm they use, and some draw a number at random; our methodology page records every formula we run.
The names were not written the same way. Full names, a nickname, a middle name or a different spelling all change the letter counts, on paper and on screen alike.
A letter was missed. The E of TRUE and the E of LOVE are the same letter in your two names and are counted under each word, so skipping the second pass moves the score.

Type the same two names into our own love calculator, and the paper answer and the screen answer match digit for digit, because the tool runs these six steps.

Paper questions we send elsewhere

Three questions arrive on this page every week and are answered in full somewhere else.

Is FLAMES different from the love calculator?

Yes: FLAMES crosses out the letters two names share and counts what is left round F, L, A, M, E, S, so it ends on a relationship word rather than a percentage. The walkthrough is FLAMES on paper.

How to put love in a calculator?

That is the keypad trick, where a number typed upside down reads as a word, and our love checker page covers it.

How to make a calculator write "I love you"?

Same trick, a different number, and it is a pocket calculator puzzle rather than a compatibility method.

The version people film for TikTok is the same counting with a different frame, and it has its own page: the TikTok compatibility test.

Questions people ask

What letters do you count in the paper love calculator?

Eight: T, R, U and E, then L, O, V and E. Count each one across both names together. The E sits in both words and is counted under each.

Do you count the E in TRUE LOVE twice?

Yes, once under TRUE and once under LOVE. Each word is added up on its own, so the same E is counted in both passes. The published descriptions do not settle it, so this is our stated convention.

What if the two names share letters?

Nothing changes. This game never crosses letters out, and it counts every appearance in both names together. Crossing out shared letters belongs to FLAMES, which is a different paper game.

Can the paper method give 100 percent?

No. The highest is 99. The score is two single digits set side by side, and two single digits cannot make 100. A tool that shows you 100 percent is running a different formula.

How to calculate love calculator?

Start by writing both names with their letters only. Count the letters of TRUE across both names, add them and reduce to one digit, then do the same for LOVE and set the two digits side by side. The six steps above work an example.
