About Athletics Points (Decathlon) Calculator

IAAF combined-event scoring uses points = A x (B - performance) ^ C for track events and A x (performance - B) ^ C for field events, with published constants per discipline. The exponent above one means the tables reward improvement at the elite end disproportionately, which is why a tenth of a second matters more at 10.4 than at 11.4.

Formulas

Track events

points = A x (B - time) ^ C

Field events

points = A x (distance - B) ^ C

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 3 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 Athletics Points (Decathlon) figure worked out?

points = A x (B - time) ^ C. IAAF combined-event scoring uses points = A x (B - performance) ^ C for track events and A x (performance - B) ^ C for field events, with published constants per discipline.

Why does this matter?

The exponent above one means the tables reward improvement at the elite end disproportionately, which is why a tenth of a second matters more at 10.4 than at 11.4.
