How is the compatibility percentage calculated?

Per dimension: 100 minus the absolute difference between the two answers, divided by 4, times 100. Identical answers give 100%, a one-step difference gives 75%, two steps gives 50%, three steps gives 25%, and opposite ends of the 1 to 5 scale give 0%. The overall percentage is the arithmetic mean of the five per-dimension scores. The math is deliberately simple — you can sanity-check any result with a calculator.

Why these five dimensions?

Values, communication, conflict, life goals, and energy levels are five places where mismatched defaults cause the most friction in long-term relationships. Therapists and couples researchers (Gottman, Johnson) point at variations of the same short list. We're not claiming five questions covers every meaningful difference — they don't — but they're a reasonable starting set for a casual self-assessment.

What do the compatibility bands mean?

Highly Compatible (85% and up) means you answered nearly the same on every dimension — a strong baseline. Strong Match (70 to 84%) is the most common shape for relationships that last: aligned on most things, diverging on one or two. Workable (50 to 69%) means real differences that are solvable when both people see them. Challenging (30 to 49%) means most answers point in different directions; relationships work from here but require deliberate compromise. Wildly Different (under 30%) means near-opposite answers — possible, but eyes-open work every week.

Does a high score mean we should be together?

No. A high score means your answers on five questions lined up. That's useful information — it suggests you'll have fewer friction points to negotiate — but it isn't a recommendation. Plenty of high-compatibility pairs don't last; plenty of mismatched pairs do. Compatibility is one input. Attraction, timing, life circumstances, the work both people are willing to do, and a hundred other variables matter more than a quiz percentage.

Does a low score mean we shouldn't be together?

No. A low score means you answered differently on most of the five dimensions. That's real information — you'll have more conversations to have, more compromise to negotiate — but it isn't a verdict. Two people with very different defaults can build a great relationship if they both see the differences clearly and choose to do the work. The friction points list at the bottom of your result is where that work usually lives.

Why is each person answering the same question?

Because compatibility is about alignment, not about either person's individual answer. If both people pick 1 ("stability first"), that's perfectly aligned — even though neither said "adventure." If one picks 1 and the other picks 5, that's the maximum mismatch on that dimension. The score measures the gap between the two answers, not the absolute value of either one.

Are my answers saved anywhere?

No. Everything runs in your browser. Your answers, the names you entered, and the calculated score never leave the page. We don't store responses; we couldn't link them back to you if we tried.

Can I take this for a friendship or a roommate, not a romantic partner?

Sure. The five dimensions — values, communication, conflict, life goals, energy — matter in any close relationship: friends, siblings, roommates, business partners, co-founders. The result's interpretation tilts toward romantic partnership in places (it's the most common use case) but the underlying math is the same. Read the friction prompts with whichever relationship you have in mind.

What should I do with the friction points?

Read the conversation prompts. Each friction point comes with a specific, practical question — not a slogan. "What does a good year look like for each of you?" works better than "do we have shared values?" because it forces concrete answers. The prompts are the actual point of the tool; the percentage is just a way to figure out which prompts matter most for you.

Relationship Compatibility Calculator

Five short questions, two people, one score. The Relationship Compatibility Calculator scores how aligned two people are across five dimensions — shared values, communication style, conflict approach, life goals, and energy levels — using a simple 1 to 5 scale for each question. The math is transparent: identical answers score 100% on that dimension, opposite ends of the scale score 0%, and the overall result is the mean of the five. You'll also see the two dimensions you click on hardest and the two where you'll friction, each with a practical conversation prompt. This is a casual self-assessment, not a relationship prophecy. Real relationships are built on a thousand small things a five-question quiz can't see — how you show up after a bad day, who you become around their family, whether you laugh at the same things. Take the score as a starting point for a conversation, not a substitute for one.

How to use

1
Optional: type each person's name. If you skip them the result reads as "Person A & Person B" — pick whatever feels less awkward.
2
Answer all five questions on the 1 to 5 scale, twice — once for each person. The questions cover values, communication style, conflict approach, life goals, and weekend energy.
3
Be honest about how you actually feel, not how you wish you felt or how you think your partner wants you to answer. The quiz is only useful if both answers are real.
4
Hit "See compatibility." You'll get an overall percentage, a band (Highly Compatible, Strong Match, Workable, Challenging, or Wildly Different), a per-dimension breakdown, your two strongest dimensions, and your two friction points with a conversation prompt for each.
5
Read the result like a starting point. If something feels off, talk about it. If something feels right, talk about that too. The percentages are a shortcut for a conversation — they're not the conversation.
