Friendship Calculator
A friendship calculator is a bit of fun: enter two names and it gives you a friendship score from 0 to 100%. The same two names always give the same score — run it today, run it next week, and the number will not change — because the score comes from a fixed calculation on the letters of the names, with no random step. You can also add how many years you have known each other and tick the interests you share: each year adds half a point (up to 10 years) and each shared interest adds 2 points, so a long friendship with lots in common scores a little higher. It is for fun only, and it says nothing real about your friendship. The real measure is how you treat each other, not a number on a screen.
Each year adds 0.5 points, up to 10 years (+5). Leave blank for no bonus.
Each shared interest adds 2 points, up to 12.

How it works
The friendship calculator takes the two names you type in and turns them into a single number between 0 and 100. It does this with a simple, fixed calculation: it looks at the letters in both names, mixes their values together in a set order, and takes the result as a percentage. There is no dice roll, no random number, and nothing that changes from one day to the next. That is why the same two names always give the same score, and why swapping the order of the names changes nothing — the calculator sorts the names first, so Alex and Sam score exactly the same as Sam and Alex.
The two extras feed the score in a fixed, open way. The years bonus is half a point per year, counting at most 10 years, so it adds between 0 and 5 points. The interests bonus is 2 points for each shared interest you tick — music, sports, movies, food, travel, or gaming — up to 12 points for all six. The total is the name score plus both bonuses, capped at 100%, and the table under the result shows each part separately, so you can see exactly where the number came from. Leave the years blank and tick nothing, and the score is just the name score, exactly as it was before these options existed.
The score comes with a short message that matches its range. A score of 90% or more is described as an unbreakable bond, 70% to 89% as a strong friendship, 50% to 69% as a solid friendship with room to grow, 30% to 49% as a friendship that is still getting started, and anything below 30% as a new connection that needs more shared time. Those labels are part of the fun, not a verdict. Two people with a score of 45% who call each other every week have a stronger friendship than two people with a score of 95% who never speak.
It is worth saying plainly what the score is not. It is not a personality test, it is not based on any research about friendship, and it cannot tell you whether someone is a good friend. It knows nothing about you except the letters in two names. A name is a label, not a life story: it carries no information about kindness, loyalty, humour, or trust, which are the things that actually decide whether a friendship lasts. If the score is high, enjoy the laugh. If it is low, enjoy the laugh too — and then go and do something together, which is worth more than any number.
That is also why the calculator is safe to share. There is no right answer to chase and no way to game it except by changing a name, which only changes the letters the calculation sees. Try your own name with a childhood friend, a classmate, a sibling, or a work friend, and compare the scores — the fun is in the surprise and the conversation that follows, not in the digits. Some people run it at parties or in group chats, where a low score between two close friends gets the biggest laugh of all, precisely because everyone in the room knows the number is wrong.
Under the surface, the calculation is deliberately simple so that it is easy to explain and impossible to mistake for something scientific. A fixed mix of the letters produces a number, the number is kept inside 0 to 100, and that is the score. Nothing is sent anywhere, nothing is stored, and your names never leave your browser. The page does not keep a history of the names you enter, so you can try as many pairs as you like in private.
Worked example
Alex wants to test his friendship with Sam, so he types "Alex" in the first box and "Sam" in the second and presses Calculate friendship. The calculator sorts the two names, mixes the letters together with its fixed calculation, and produces a whole-number score between 0 and 100 — the same score it would produce for Sam and Alex, and the same score it would produce if Alex ran the same two names again tomorrow.
Suppose the result is 82%. The page shows "Friendship score: 82%" with the message that Alex and Sam have a strong friendship, and the table below repeats both names with the score. Alex can share the 82% with Sam for a laugh, and the two of them can argue, as friends do, about whether the number should have been higher. The number itself proves nothing — the fact that Alex thought to run it, and that Sam laughs when he sees it, says more about their friendship than the score ever could.
Try it the other way round to see the rule in action: enter "Sam" first and "Alex" second, and the score is exactly the same. Then try a different pair — a parent, a sibling, a new classmate — and notice that the score changes only because the letters changed. That is the whole trick, and knowing the trick is part of the fun: the calculator is a game with names, not a judge of people.
FAQ
How does the friendship calculator work?
It turns the two names you enter into a score from 0 to 100% using a fixed calculation on the letters of the names. The same two names always give the same score, in either order, because the calculation never changes and no random numbers are involved.
Is the friendship score real?
No. The score is for fun only and says nothing real about your friendship. It starts from the letters in two names, then adds a small bonus for how long you have known each other and for shared interests — but those are just numbers you type in, not a measure of kindness, loyalty, or trust, which are what actually make a friendship strong.
Do the years and shared interests change the score?
Yes, by a little. Each year you have known each other (up to 10 years) adds half a point, and each shared interest you tick adds 2 points, up to 12. The total is capped at 100%. Leave both blank and the score is just the name score, exactly as before.
Why do the same names always give the same score?
Because the score comes from a deterministic calculation: the same input always produces the same output. There is no random step, no daily change, and no hidden factor, so you can run the same two names ten times and get the same number every time.
Does the order of the names change the score?
No. The calculator sorts the two names before it works out the score, so entering Alex and Sam gives the same result as entering Sam and Alex. Friendship works both ways, and the score treats it that way.
Can I share my friendship score?
Yes. Share it with your friend for a laugh, and remember it is only a bit of fun. A low score does not mean a weak friendship, and a high score does not mean a perfect one — the real test is how you show up for each other.
