Friendship Compatibility Calculator

Measure how strong your friendship is based on values, habits, communication, and trust. Answer a few quick questions about you and your friend to get a friendship score and personalized tips.

1. Tell us about your friendship

1 = Very different values, 10 = Very aligned on what matters in life.

Think schedule, hobbies, social energy, reliability.

How well you talk, listen, and repair after disagreements.

1 = I often hold back, 10 = I can be fully myself and feel safe.

1 = One-sided, 10 = We both invest time and energy fairly.

How the Friendship Compatibility Calculator works

This tool turns the abstract idea of “friendship” into a simple, transparent scoring model. It does not judge you or your friend; it highlights patterns so you can better understand your relationship.

Scoring model

The total friendship score is on a 0–100 scale and is built from:

  • Shared values & goals – 25%
  • Habits & lifestyle compatibility – 20%
  • Communication & conflict resolution – 20%
  • Trust & emotional safety – 25%
  • Balance of effort – 10%

Friendship Score = (Values × 2.5) + (Habits × 2.0) + (Communication × 2.0) + (Trust × 2.5) + (Effort × 1.0)

Each slider is from 1–10. We multiply by the weight to get a 0–100 score.

The calculator also adjusts the interpretation based on how long you’ve known each other and how often you talk. For example, a medium score in a very new friendship can still be promising, while the same score in a long-term friendship may signal unresolved issues.

How to read your friendship score

  • 80–100: Strong, resilient friendship with solid foundations. Differences exist, but you handle them well.
  • 60–79: Generally healthy friendship with a few friction points. Small changes could make a big difference.
  • 40–59: Mixed signals. Some important needs may not be met; honest conversations could clarify things.
  • 0–39: Likely misalignment in values, trust, or effort. It may still be meaningful, but it may not feel balanced or safe.

Tips to strengthen any friendship

1. Communicate expectations clearly

Many friendship conflicts come from unspoken expectations: how often to talk, how to handle cancellations, what “support” looks like during hard times. A simple check-in like “What does being a good friend look like to you?” can prevent years of quiet resentment.

2. Repair after conflict

Strong friendships are not conflict-free; they are repair-rich. Owning your part, apologizing specifically, and asking what your friend needs next time are powerful ways to rebuild trust.

3. Balance giving and receiving

Friendships feel safest when both people give and receive: time, emotional support, practical help, and appreciation. If you notice a pattern of one-sided effort, talk about it early instead of letting resentment grow.

4. Accept differences in personality

Some friends are planners, others are spontaneous. Some text daily, others prefer deep monthly catch-ups. Compatibility doesn’t mean being identical; it means understanding and respecting each other’s style.

Limitations and disclaimer

This calculator is an educational and self-reflection tool. It is not a clinical assessment, and it cannot capture every nuance of your relationship. Use it as a starting point for reflection and conversation, not as a final verdict on your friendship.
