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.

Would you like to make the sportcalculators.com better by answering a few short questions?

The decathlon calculator is easy to use. Select the calculation direction at the top of the calculator and then enter either results or points to text fields. When you change the focus out from a text field the result/points of the event are calculated. If manual timing is used in running events use the checkbox below each running event to adjust the calculation accordingly. How it effects the calculation is explained below.

### Decathlon

Decathlon is a combined event in athletics with ten events. Events are usually competed on two consecutive days on track or field. Each event is scored according to a point system and points achieved determine the winner. The point system is based on the result not the position in the event. Scoring over 9000 points is really rear and has been done only a few times. The list for the best results all time is available on IAAF's site. Use the decathlon calculator above to find out what kind of performance is needed to get 1000 points in each event and break the world record.

### Events

The events are always competed in the same following order.

**Day 1**

- 100 metres
- Long jump
- Shot put
- High jump
- 400 metres

**Day 2**

- 110 metres hurdles
- Discus throw
- Pole vault
- Javelin throw
- 1500 metres

### How to Calculate Decathlon Points

Decathlon points are calculated using the following formulas:

- Points = INT(A(B — P)
^{C}) for track events (faster time produces a better score) - Points = INT(A(P — B)
^{C}) for field events (greater distance or height produces a better score)

INT in the formula means that points are rounded to nearest integer. P is the result of an event. It is measured in seconds for track events, in meters for throwing events and in centimeters for jumping events. A, B and C in the formula are taken from a table. Since 1984 the table has been the following:

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 |

All times used should be automatically measured. If manual timing is used 0.24s is added to 100m and 110m hurdles and 0.14s to 400m race.
