Compatibility is not just chemistry — it is alignment on the things that matter most over a lifetime together. Research from the Gottman Institute and attachment theory consistently shows that the couples who thrive long-term are not the ones who fight the least or feel the most passionate early on. They are the ones who share core values, communicate honestly, trust each other deeply, and handle conflict without contempt. This Love Compatibility Calculator evaluates your relationship across six dimensions that research has identified as the strongest predictors of long-term relationship success: Core Values (22%), Communication (20%), Emotional Intimacy (18%), Trust and Safety (16%), Lifestyle Fit (14%), and Attraction (10%). Each dimension is rated 1–5 and weighted by its evidence-based importance to relationship longevity. The result is a weighted compatibility score from 0 to 100, a radar chart showing your relationship's strength profile, a dimension breakdown with individual scores, and a personalized growth plan identifying your specific strengths and the gaps that most deserve attention. This tool is designed for couples at any stage — whether you are in a new relationship trying to assess long-term potential, an established couple looking for a structured framework to identify growth areas, or anyone navigating the question of whether this is the right person for the long term. The calculator updates in real time as you rate each dimension, so you can experiment with how improving specific areas affects your overall compatibility score.
- ·Ratings reflect current reality, not aspirational standards — honest answers produce the most useful results
- ·Weights are based on longitudinal relationship research; they represent population-level predictors, not guarantees
- ·Both partners rating independently then comparing reveals more than one person rating for both
- ·This is a diagnostic tool, not a verdict — low scores identify areas to address, not reasons to end relationships
- →You want a structured, research-backed way to assess compatibility beyond gut feeling
- →You and your partner want to identify specific dimensions to work on together
- →You are early in a relationship and want to think through long-term potential
- →You are questioning whether fundamental incompatibilities exist
- →You want to compare your independent ratings with your partner's to surface discrepancies
- →You are preparing for couples therapy and want a baseline assessment to share
Marcus and Priya have been together for 2 years and are starting to think seriously about their future. Marcus rates their core values alignment at 4 (High) but their communication at 2 (Low) — they avoid difficult conversations. Priya rates communication at 3 (Moderate). Their compatibility score: 68/100 — Good Foundation. The radar chart reveals a clear spike downward on communication and lifestyle fit. The calculator identifies communication as the highest-priority growth area given its 20% weight, and provides a specific framework for improving conflict conversations using Gottman techniques.
- ✕Rating how you wish things were rather than how they actually are — the calculator's value depends entirely on honest input
- ✕Treating a single score as a verdict rather than a conversation framework
- ✕Ignoring the radar chart and only looking at the total score — dimension-level information is more actionable
- ✕Assuming a high attraction rating compensates for low values alignment — research shows the opposite pattern over time
How is the love compatibility score calculated?
The score is a weighted average of 6 dimensions: Core Values (22%), Communication (20%), Emotional Intimacy (18%), Trust and Safety (16%), Lifestyle Fit (14%), and Attraction (10%). Each dimension is rated 1–5, converted to a 0–100 scale, then multiplied by its weight. The weights are drawn from longitudinal relationship research showing which factors most predict long-term relationship satisfaction and stability.
What compatibility score is considered good?
65+ indicates a good foundation with clear strengths, though no relationship is without growth areas. 80+ reflects high compatibility across most dimensions — this doesn't mean things won't require work, but the foundational elements are strong. Scores below 50 often point to one or more high-weight dimensions (particularly values or trust) that have significant gaps worth addressing honestly.
Should both partners fill this out separately?
Yes, ideally. When each partner rates independently then compares, discrepancies are themselves valuable data. If one partner rates communication quality at 4 and the other at 2, that gap reveals different subjective experiences of the relationship — a powerful conversation starter.
Can a couple with a low score improve compatibility?
Yes, with important nuance. Dimensions like communication and emotional intimacy are highly trainable through deliberate practice, couples therapy, and structured frameworks. Core values are less flexible — fundamental disagreements about children, religion, or lifestyle usually cannot be fully resolved through communication skill alone.
Why does attraction have the lowest weight at 10%?
Research consistently shows that attraction — both physical and intellectual — matters most early in relationships and declines in predictive power over time. After the first 2 years, values alignment, conflict resolution quality, and genuine friendship quality become the dominant predictors of long-term satisfaction. Couples who rate attraction highly but values low tend to experience the reverse over time.
