RICE Score Calculator (Prioritise Features and Projects)

Scores and compares two ideas with the RICE method — reach, impact, confidence and effort — so you can see which to do first.

Results

RICE score of idea A 533.3
RICE score of idea B 450.0
A compared with B 1.19
Which to do first Idea A

What this tool does

RICE, developed at Intercom, turns a gut feeling about priorities into a number: how many people it reaches in a period, how much it moves each of them (3 for massive down to 0.25 for minimal), how sure you are of those guesses (100 %, 80 % or 50 %), divided by the effort in person-months. Dividing by effort is what stops a big, vague project beating a small, sure win. The score is for ranking ideas against each other, not for forecasting; the confidence factor is there to punish optimistic guesses, so be honest with it.

Formula

RICE = Reach × Impact × Confidence ÷ Effort (impact scale 3 / 2 / 1 / 0.5 / 0.25)

Limitations

  • The result is an estimate based only on the values you type. Real situations often include factors this calculator does not know about.
  • The default values are typical reference figures, not measurements of your situation. Replace them with your own data whenever you have it.
