Decathlon Calculator
This calculator allows you to calculate decathlon score. You can calculate points from results or results from points. You can use the results from points calculation to estimate needed results for each event.
How to Use the Calculator?
Select the calculation direction at the top and enter results or points in the text fields. When you move focus away from a field the score is calculated. Use the manual timing checkbox for running events if needed.
Decathlon
Decathlon is a combined event in athletics with ten events competed over two days. Each event is scored using a point system. Scoring over 9000 points is very rare. See the IAAF site for all-time top lists.

How to Calculate Decathlon Points
- Points = INT(A(B — P)^C) for track events
- Points = INT(A(P — B)^C) for field events
P is the result, measured in seconds for track events, meters for throwing, centimeters for jumping. Since 1984 the A, B and C constants are:
| Event | A | B | C |
|---|---|---|---|
| 100 m | 25.4347 | 18 | 1.81 |
| Long jump | 0.14354 | 220 | 1.4 |
| Shot put | 51.39 | 1.5 | 1.05 |
| High jump | 0.8465 | 75 | 1.42 |
| 400 m | 1.53775 | 82 | 1.81 |
| 110 m hurdles | 5.74352 | 28.5 | 1.92 |
| Discus throw | 12.91 | 4 | 1.1 |
| Pole vault | 0.2797 | 100 | 1.35 |
| Javelin throw | 10.14 | 7 | 1.08 |
| 1500 m | 0.03768 | 480 | 1.85 |
If manual timing is used: add 0.24s to 100m and 110m hurdles, 0.14s to 400m.
