Compatibility Percentage Calculator

Work out compatibility percentage instantly with clear inputs, formula shown and shareable results.

About Compatibility Percentage Calculator

The score is a transparent rule: the Jaccard overlap of the two names' letter multisets, mapped onto a 40 to 100 band so no pairing scores zero. This is entertainment, not analysis. The arithmetic is fully deterministic and repeatable, and it says nothing whatever about any real relationship.

Formulas

Letter overlap

overlap = shared letter count / combined distinct letter count x 100

Score

score = 40 + overlap x 0.6, capped at 100

Worked example

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Compatibility Percentage figure worked out?

overlap = shared letter count / combined distinct letter count x 100. The score is a transparent rule: the Jaccard overlap of the two names' letter multisets, mapped onto a 40 to 100 band so no pairing scores zero.

Why does this matter?

This is entertainment, not analysis. The arithmetic is fully deterministic and repeatable, and it says nothing whatever about any real relationship.

What do I need to enter?

Enter first name, second name. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
