About Friendship Score Calculator

Four inputs are each scaled to a capped point allocation, thirty points for shared interests and contact frequency, twenty five for longevity and fifteen for reciprocal favours, then added. This is a transparent scoring rule for fun rather than a psychological instrument; the weightings are stated so you can see exactly what drives the number.

Assumptions and limits

The result is derived only from the 4 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 1 decimal place, 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.
