Enter the max die roll (sum of all dice) and the number of dice into the calculator to determine the average dice roll value.

Dice Average Formula

The following equation is used to calculate the average value of a set of dice.

AV = ( (M + 1 )/ 2 ) * N
  • Where AV is the average dice value
  • M is the max value of all dice
  • N is the total number of die

To calculate the average dice value, add 1 to the max value of all dice, divide the result by 2, then multiply that result by the number of dies.

Dice Average Definition

A dice average is defined as the total average value of the rolling of dice. That is the average of the values facing upwards when rolling dice.

Dice Average Example

Let’s look at a simple example of how to use the equation above.

  1. First, we need to determine the max value of 1 dice. For this example will assume standard dice, so the max value is 6.
  2. Next, we need to determine the number of dice. Simply count them up. For this, we will say 10 dice.
  3. Finally, enter the information into the formula above. We get the results (6+1/2)*6 = 21 average roll value.
