Decathlon Score Calculator

Decathlon scoring doesn't compare raw times and distances directly — it converts every one of the ten events into points using the official IAAF/World Athletics tables (the 2001 edition, still current), so a 100 m sprint and a javelin throw can be summed on the same scale. This calculator implements the exact formula those tables encode: for track events (100 m, 400 m, 110 m hurdles, 1500 m), where a lower number is better, points = A × (B − performance)^C; for field events (long jump, shot put, high jump, discus, pole vault, javelin), where a higher number is better, points = A × (performance − B)^C. Each event has its own published A, B, and C constants calibrated to reward marginal improvements differently — sprint times near world-record pace earn disproportionately more points per tenth of a second than pedestrian ones.

Every event score is floored to a whole number, matching how official competition scoring works, and the total across all ten events is your decathlon score. The calculator also splits the total into Day 1 (100 m, long jump, shot put, high jump, 400 m) and Day 2 (110 m hurdles, discus, pole vault, javelin, 1500 m) subtotals, the traditional competition-day grouping, and grades your total against benchmark thresholds from high-school varsity up through Olympic medal contention. One easy-to-miss detail: while you enter jump and vault marks in metres, the underlying IAAF tables for long jump, high jump, and pole vault are calibrated in centimetres, so the calculator converts those three internally before scoring — shot put, discus, and javelin distances are scored directly in metres.
