Dice Average Calculator
A dice average calculator is used to compute the expected average outcome when rolling one or more dice. This calculator is particularly useful in game design, dice probability studies, and various tabletop gaming scenarios.

Dice Average Calculation Formula
The Dice Average Calculation Formula for a single die is:
Average = (Minimum + Maximum) ÷ 2
For multiple dice of the same type, the formula becomes:
Average = Number of Dice × ((Minimum + Maximum) ÷ 2)
Let’s calculate the average for rolling 3d8 (three 8-sided dice).
- Minimum roll on a d8: 1
- Maximum roll on a d8: 8
- Number of dice: 3
Average for one d8 = (1 + 8) ÷ 2 = 4.5 Average for 3d8 = 3 × 4.5 = 13.5Therefore, when rolling 3d8, the expected average outcome is 13.5.
