RICE is a prioritization framework created by Intercom that scores features based on Reach, Impact, Confidence, and Effort. It provides data-driven prioritization that removes bias from product decisions. The formula is RICE Score = (Reach x Impact x Confidence) / Effort. A good benchmark is scores above 100 are high priority, above 500 are slam dunks. PM Toolkit's free RICE calculator helps product managers calculate feature priority with auto-calculated scores with portfolio analysis and scoring insights.
What is RICE Prioritization?
RICE is a prioritization framework developed by Intercom that scores features by four factors: Reach, Impact, Confidence, and Effort. It helps product managers make objective, data-driven roadmap decisions.
RICE Score Formula
RICE Score = (Reach × Impact × Confidence) ÷ Effort
RICE Components Explained
- Reach
- Number of users or events affected per quarter (e.g., 1,000 users/quarter)
- Impact
- Scale from 0.25 (minimal) to 3 (massive) measuring effect on individual users
- Confidence
- Percentage from 50% (low) to 100% (high) reflecting certainty in estimates
- Effort
- Person-months of work required to complete the project
Interpreting RICE Scores
RICE scores are relative - compare features within your own backlog rather than against absolute thresholds. Higher scores indicate better return on investment. Features with scores significantly above your backlog average should be prioritized first.

Start Prioritizing with RICE
RICE scoring helps you prioritize features by balancing Reach, Impact, Confidence, and Effort. Add your first initiative or load sample data to get started.
Quick Formula
RICE Score = (Reach × Impact × Confidence) ÷ Effort- • Reach: How many users per quarter
- • Impact: 3 (massive) to 0.25 (minimal)
- • Confidence: 100% (high) to 50% (low)
- • Effort: Person-weeks to complete
Understanding the RICE Prioritization Framework for Product Teams
Intercom developed RICE to compare initiatives using Reach, Impact, Confidence, and Effort. It produces a ranking from those estimates, giving the team a consistent basis for discussing feature priorities.
RICE vs ICE: Choosing the Right Framework
Use RICE when: Use RICE when you have Reach data and Effort estimates to compare features for a roadmap. Review uncertain inputs before relying on the ranking.
Use ICE when: Use ICE for a quick comparison of experiments or smaller features when detailed Reach data is unavailable.
RICE Scoring Best Practices
- Reach (Number): Estimate how many users/customers will be affected per time period (monthly/quarterly)
- Impact (1-3): Quantify the impact per person affected - 3 (massive), 2 (high), 1 (medium), 0.5 (low), 0.25 (minimal)
- Confidence (%): Express certainty as percentage - 100% (high evidence), 80% (medium), 50% (low evidence)
- Effort (Person-Months): Total team effort across all disciplines - development, design, QA, etc.
- Team Calibration: Score 3-5 reference features together to establish consistent standards
Common RICE Implementation Mistakes
Teams often struggle with: 1) Using inflated Reach numbers without proper measurement, 2) Confusing Impact with total business value instead of per-person impact, 3) Overestimating Confidence without supporting data, 4) Underestimating hidden Effort in dependencies and maintenance, and 5) Not updating scores as new information becomes available.
How to Interpret RICE Scores
RICE is a relative-ranking tool, so there is no universal threshold that marks a feature as "high priority." A score only means something next to the other items in the same list. Intercom's original write-up warns against reading absolute cutoffs into the number. Sort your backlog by RICE and compare the top items against each other: a score of 800 is twice as high as 400, which tells you where to focus first.
Strategic Applications Beyond Features
RICE can also help compare experiments, campaigns, process changes, or hiring initiatives when Reach, Impact, Confidence, and Effort have useful definitions. Include qualitative considerations when a strategic decision depends on factors the score leaves out.
What is RICE Scoring?
Intercom's RICE framework combines Reach, Impact, Confidence, and Effort into a prioritization score. Compare scores using consistent estimates and review the tradeoffs behind the ranking.
RICE Formula
RICE Score = (Reach × Impact × Confidence%) / Effort

“RICE scoring saved my team from the loudest-voice-wins trap. Before we adopted it, roadmap decisions were driven by whoever made the most compelling pitch. Now, Reach and Impact force us to quantify assumptions, and the scores give us a shared language for saying no to good ideas in favour of great ones.”
Common questions
What is the RICE prioritization framework?
Intercom developed RICE to rank product features using Reach, Impact, Confidence, and Effort. Reach is the number of users affected per quarter. Impact is the effect per user on a 0.25-3 scale, Confidence is your certainty as a percentage, and Effort is the person-months needed. RICE Score = (Reach x Impact x Confidence%) / Effort. The free calculator scores and ranks features, with calibration guidance to help your team use the same scale.
How do you calculate a RICE score?
RICE Score = (Reach × Impact × Confidence) ÷ Effort. For example: if Reach=1000 users, Impact=2 (high), Confidence=80%, and Effort=3 person-months, then RICE = (1000 × 2 × 0.8) ÷ 3 = 533. Higher scores indicate higher priority. PM Toolkit's RICE calculator computes and ranks scores automatically.
When should I use RICE vs ICE scoring?
Use RICE when you have reach data and want detailed analysis. Use ICE for faster scoring or when reach metrics aren't available. RICE is better for strategic roadmap planning with quantitative data, while ICE is ideal for rapid experiment prioritization.
What's a good RICE score?
There is no universal cutoff. RICE is built for relative ranking within the same backlog, and Intercom's original framework warns against absolute thresholds. Compare scores against each other: the highest scores get built first, regardless of the absolute number. A score of 800 is twice as high as 400. Focus on ranking items against each other rather than hitting a fixed target.
How do you score Impact in RICE prioritization?
Impact represents the effect per person reached. Use the standard scale: 3 (massive impact), 2 (high), 1 (medium), 0.5 (low), 0.25 (minimal). Focus on per-user impact, not total business impact (that's calculated by Reach × Impact).
What should be included in RICE Effort estimation?
Effort should include total person-months across all team members: developers, designers, QA, product managers, and any other contributors. Include time for testing, documentation, and rollout. Many teams underestimate by 50-100% by only counting development time.
