RICE Scoring Model: How to Prioritise by Reach, Impact, Confidence, and Effort

What is the RICE scoring model?

RICE is a prioritisation formula that estimates initiative value by combining reach, impact, confidence, and effort. It is widely used by product teams for roadmap and backlog decisions.

RICE formula

RICE score = (Reach x Impact x Confidence) / Effort

Higher scores generally indicate better candidates for near-term delivery.

How to score with RICE

1. Estimate reach over a fixed period.
2. Assign impact using a consistent scale.
3. Set confidence based on evidence quality.
4. Estimate effort in person-weeks or points.
5. Compute scores and review assumptions.

RICE example

Initiative A: Reach 2,000, Impact 2, Confidence 80%, Effort 5 gives score 640. Initiative B: Reach 1,200, Impact 3, Confidence 70%, Effort 2 gives score 1,260. Initiative B would generally rank higher despite lower reach.

Pros and cons

Pros: clear formula, easy comparison, and better alignment in planning discussions.

Cons: quality depends on estimation discipline and consistent scoring definitions.
