Friendship Compatibility Calculator
Are you Soulmates, Best Friends, or Casual Pals? Enter both names, optional zodiac signs, and answer five quick questions for a 0-100% friendship score with strengths and challenges.
Quick Answer
The friendship compatibility calculator returns a 0-100% score by combining three signals: name vibe from letter overlap (30%), zodiac element pairing (25%), and friendship alignment from five short questions (45%). The result maps to a label — Acquaintances, Casual Pals, Solid Friends, Best Friends, or Soulmates — plus bullet-point strengths and challenges. Same inputs always produce the same score. Entertainment only.

About This Tool
The Friendship Compatibility Calculator turns two names, two zodiac signs, and five quick questions into a 0-100% score, a friendship label, and a short list of strengths and challenges. It's deterministic, which means the same inputs always produce the same number — easy to share with the friend in question and dare them to match the result.
Where the love calculator leans into chemistry (names and stars), the friendship calculator leans into the day-to-day stuff that actually keeps friendships alive: how you handle conflict, how much social energy you have, what you like to do together, how you text, and what kind of friendship you're both looking for. The answer-driven dimension carries 45% of the score for that reason — a single weekend can tell you more about a friendship than any zodiac matrix.
The Five Friendship Labels
The score maps to one of five labels. Acquaintances (0-35%): you orbit each other but don't reach out. Casual Pals (36-55%): pleasant, low-stakes, low-frequency. Solid Friends (56-75%): consistent, reliable, easy. Best Friends (76-88%): inside jokes and mutual rescue missions. Soulmates (89-100%): the rare kind that survives moves, marriages, and decades. None of these are static — friendships move up and down the scale all the time.
How Name Vibe Works
We compare the letter frequencies of both names. Shared letters increase the overlap ratio, unique letters decrease it. The result gets scaled and combined with a deterministic hash so similar overlap ratios still produce distinct scores. Order doesn't matter — “Sam & Riley” and “Riley & Sam” produce the same number.
How Zodiac Friendship Works
Same as the romantic version: Fire (Aries, Leo, Sagittarius), Earth (Taurus, Virgo, Capricorn), Air (Gemini, Libra, Aquarius), Water (Cancer, Scorpio, Pisces). Same-element pairs score highest because they share defaults around energy and emotion. Complementary cross-element pairs (Fire-Air, Earth-Water) score next. Other cross-element pairings score lower but never zero — opposites can build excellent long-haul friendships when both people lean into the difference.
How the Friendship Questions Work
Five questions cover the practical compatibility layers: conflict style (talkers vs. coolers vs. avoiders), social battery (extrovert to hermit), favorite shared activity (food, outdoors, games, couch, making things), texting style (constant, burst, memes, voice), and friendship vibe (deep, fun, growth, comfort). Each of you picks an option. Matches add to the alignment score. The strengths and challenges section then translates the specific match-or-mismatch patterns into plain-language bullets.
What This Tool Won't Do
It won't tell you whether to keep a friendship, drop one, or repair one. It won't replace an actual conversation about how the friendship is going. It's a calculator that turns a few inputs into a number, the same way pop quizzes in teen magazines used to. Take the result, send it to your friend, argue about which strengths the algorithm got right.
