Built for small teams that want a quick prioritisation gut-check

How many users this touches in a given period.

Typical scale: 0.25, 0.5, 1, 2, or 3.

Enter as a percentage, from 0 to 100.

Team-weeks, person-months, or whatever unit you use consistently.

Based on your inputs, this looks like a strong candidate.

Formula

RICE = Reach × Impact × Confidence ÷ Effort

Confidence is treated as a percentage, so 80 means 0.8 in the formula.

How to think about the inputs

  • • Reach: how many users this affects in a fixed period — for example per month or per quarter.
  • • Impact: how much it matters to each user affected.
  • • Confidence: how much you trust your numbers.
  • • Effort: the work required, using one consistent unit across ideas.

Common impact scale

  • • 3 = massive
  • • 2 = high
  • • 1 = medium
  • • 0.5 = low
  • • 0.25 = minimal

Worked example

If a feature reaches 100 users, has an impact of 2, confidence of 80%, and effort of 4, the score is:

(100 × 2 × 0.8) ÷ 4 = 40

Quick note

RICE is useful for comparing options, not pretending product strategy is solved by a spreadsheet. If two ideas get similar scores, use your judgement.

When RICE helps

  • • Comparing a shortlist of ideas.
  • • Explaining why one feature moves ahead of another.
  • • Stopping the loudest request from winning by default.
  • • Giving small teams a shared way to discuss tradeoffs.

When RICE is not enough

  • • Legal or security work still matters, even with a boring score.
  • • Strategic bets can look weak before the evidence exists.
  • • A bad estimate with high confidence is still a bad estimate.
  • • If the inputs are nonsense, the output will be too.
