Love Calculator

What is a love calculator?

A love calculator is a playful online game that turns two names into a "love percentage". Type your name and the name of your crush, partner or best friend, and this love calculator by name gives a score from 35% to 100% along with a classic FLAMES result. It is great for a laugh with friends, a party game or a light-hearted message to your partner.

Please remember: it is just for fun. No calculator can measure love. The score is produced by a simple formula applied to the letters of the two names – it knows nothing about the people behind them.

How to use the love calculator

1. Type your name in the first box – first name only or full name, it's your choice.
2. Type the other person's name in the second box.
3. Your love percentage and FLAMES result appear instantly. Change a spelling or add a surname to see a different score.

The order of the names does not matter: "Rahul and Priya" gives exactly the same result as "Priya and Rahul". Capital letters, spaces and punctuation are ignored.

How does the love calculator work?

People often ask whether a love calculator is real or fake, and how the love percentage is calculated. Here is exactly what this one does:

1. It lowercases both names and removes spaces and symbols.
2. It sorts the two names alphabetically so the order you type them in doesn't change anything.
3. It runs the letters through a hash – a formula that turns text into a number, the same idea computers use to check files.
4. It maps that number to a percentage between 35 and 100. Two identical names always score 100%.

Because the formula is fixed, the same pair of names always gives the same score – so you can share your result and your friends will see the same number. But the result has no scientific meaning; a small spelling change can move it a lot. That is the honest answer to "are love calculators accurate?" – no, and they are not meant to be.

Love calculator formula

Love % = 35 + (hash of both names mod 65)

The hash is order-independent, so the score belongs to the pair, not to who typed first.

What is FLAMES? The paper love game

FLAMES is the love calculator game many of us played on paper at school in India. Each letter stands for a relationship: Friends, Lovers, Affection, Marriage, Enemies and Siblings.

How to calculate love on paper with names (FLAMES)

1. Write both names and strike out the letters they share, one for one. For RAHUL and PRIYA, strike one R and one A from each.
2. Count the letters left: H, U, L from Rahul and P, I, Y from Priya = 6.
3. Write F L A M E S and count along it 6 times, starting at F. Cross out the letter you land on (S).
4. Continue counting 6 from the next letter, wrapping around, until one letter remains.

For Rahul and Priya the last letter standing is M – Marriage, which is what the calculator shows. The love calculator above runs FLAMES automatically so you can check your paper answer.

How to calculate love percentage by names on paper

Another school method is the "LOVES" count: count how many times the letters L, O, V, E and S appear in both names together, write the five counts in a row, then add neighbouring pairs to make a shorter row, repeating until two digits remain. That two-digit number is the love percentage. It is just as random as any online love percentage calculator – and just as much fun.

Love calculator by date of birth and zodiac

Some sites offer a love calculator by date of birth, by zodiac sign, rashi or Chinese zodiac, and call it astrology-based compatibility. Those results are also not scientific. This page uses names only, so you don't need to share anyone's birth date. If you want to know how many days you have been together, the date calculator counts the days between your first date and today, and the age calculator gives exact ages.

Fun ways to use the love calculator

• Love calculator for couples: compare your score with your partner's nicknames, full names and pet names – the highest one wins.
• Love calculator for friends: test your friendship score with your best friend or siblings.
• Party game: pair up names of celebrities or fictional characters and guess the score before you reveal it.
• Love calculator for kids: a harmless spelling game – kids can try their names with pets, favourite cartoons or family members.

Real love is not a number

Healthy relationships are built on trust, respect, kindness, honest conversations and time spent together – none of which fit into a percentage. If the love calculator gives you 42%, don't worry; if it gives you 99%, enjoy the moment but keep putting in the effort. Treat the result the way you would a fortune cookie: a smile, not a decision.

Love calculator: how does it work, exactly?

People often ask "love calculator, how does it work?" Here it is in plain words: the two names are cleaned (spaces and symbols removed), put in alphabetical order so the order you type them does not matter, and turned into a number with a fixed formula. That number becomes a score between 35% and 99%, and identical names give 100%. There is no magic and no data about you – it is a game.

Love calculator by name and date of birth

This love calculator uses names only. A love calculator by name and date of birth, with birthdays or zodiac signs, is just as random: a birth date cannot measure feelings. For a playful twist, compare your zodiac signs – fire signs (Aries, Leo, Sagittarius) are traditionally paired with air signs – and enjoy it the same way you enjoy a horoscope.

Love calculator by age

A love calculator by age is also only for fun. Age tells you nothing about how well two people get along; shared values, respect and kindness matter far more.

Love calculator with photo

A love calculator with a photo cannot read love from a face either. This one never asks for pictures – you only type two names, and nothing is uploaded.

Love calculator name for a boy and a girl

Type the boy's name and the girl's name in either box – the result is the same both ways. Use first names for a quick game or full names for a different score.

Love calculator: how many days and months have you been together?

A love calculator for how many days, or how long you have been together, is really a date question. Enter the day you met and today in our date calculator to get the exact days, weeks and months. For example, 14 February 2025 to 14 February 2026 is 365 days – a perfect excuse to celebrate an anniversary.

Love calculator marriage and quiz ideas

A love calculator for marriage gives no real prediction, so never use a score to decide something serious. It works better as a party game: turn it into a love calculator quiz where friends guess the percentage before you press the button, and the closest guess wins.

Love calculator in Hindi, Tamil and English

Names can also be typed in Hindi (Devanagari), for example राहुल and प्रिया, so the love calculator works in Hindi as well as in English. For Tamil or other scripts, type the names in English letters. Love calculator kaise kare? Dono naam likhiye aur result dekhiye – bas itna hi.

Love calculator code in Python and JavaScript

Writing a love calculator is a favourite beginner project. Love calculator code in Python can be this short:

def love(a, b): key = ''.join(sorted([a.lower(), b.lower()])); return 35 + sum(ord(c) for c in key) % 65

And love calculator JavaScript code for the same idea:

function love(a, b) { const key = [a.toLowerCase(), b.toLowerCase()].sort().join(''); let s = 0; for (const c of key) s += c.charCodeAt(0); return 35 + s % 65; }

Both give the same score whichever order the names are typed, which is the trick behind every love calculator in Python or JS.

Love calculator by me: build your own

Building your own for a school project? Add FLAMES as a second result – it only needs letter counting, and friends love seeing both.
