What is RICE (RICE Scoring)?
A prioritization framework that scores initiatives by Reach, Impact, Confidence, and Effort to produce an objective ranking of the product backlog.
RICE is a prioritization scoring framework developed at Intercom that evaluates product initiatives across four dimensions: Reach, Impact, Confidence, and Effort. By combining these four factors into a single score, RICE helps product teams move beyond gut-feel prioritization and create an objective, defensible ranking of their backlog. Higher RICE scores indicate initiatives that deliver more value per unit of effort at high confidence.
Formula
RICE = (Reach x Impact x Confidence) / EffortReach: number of users affected per time period (e.g. 500 users/quarter). Impact: effect per user on a scale of 0.25 (minimal) to 3 (massive). Confidence: how sure you are about estimates, as a percentage (0-100%). Effort: person-weeks of work required. Example: Reach=500, Impact=2, Confidence=80%, Effort=4 weeks. RICE = (500 x 2 x 0.8) / 4 = 200.
Industry Benchmarks
- RICE scores are relative, not absolute - the value comes from ranking, not the raw number
- Impact scale: 3 = massive, 2 = high, 1 = medium, 0.5 = low, 0.25 = minimal
- Confidence above 80% is high, 50-80% is medium, below 50% should trigger more discovery
- Effort is typically estimated in person-weeks or story points per person
- Teams using RICE report 20-30% improvement in prioritization consistency
When to Use RICE
- Ranking a large backlog of features or experiments to identify the highest-value work
- Facilitating alignment in cross-functional planning sessions with an objective scoring system
- Comparing a new feature request against existing backlog items using the same criteria
- Building a data-driven argument for deprioritising low-RICE items pushed by stakeholders
- Inflating Reach or Impact estimates to make a favoured initiative score higher, which destroys the framework's objectivity
- Ignoring Confidence entirely and treating all estimates as certain, which leads to over-investment in speculative bets
- Applying RICE to items that are already committed (legal requirements, platform dependencies) - only score discretionary work
- Score Confidence conservatively - teams consistently overestimate how much they know about impact before building
- Run a calibration session where the team scores 3-5 past initiatives to align on what "Impact = 1" and "Impact = 3" look like for your product
- Combine RICE with strategic themes: the highest-RICE item might not align with your current quarter's strategic focus
