RICE = Reach × Impact × Confidence ÷ Effort, a single score to rank ideas. Higher is better; the top row is highlighted. Saved locally.
How the rice prioritization calculator works
RICE is a prioritisation framework from Intercom that scores each idea with a single number: Reach × Impact × Confidence ÷ Effort. Reach is how many people it affects in a period; Impact is how much it moves the needle per person (a scale like 3 = massive, 1 = medium, 0.5 = low); Confidence is how sure you are, as a percentage; and Effort is the work required, usually in person-months. The three benefits sit on top and effort is the denominator, so high-value, low-effort ideas rise to the top. Enter your numbers and the table ranks everything automatically. As a worked example, a feature reaching 1,000 users per quarter with medium impact (1), 80% confidence and 2 person-months of effort scores 1,000 × 1 × 0.8 ÷ 2 = 400; the units are "impact per person-month", so only the ranking matters, not the absolute figure.
RICE's honesty is in the Confidence factor. It makes you discount ideas built on guesswork, which is exactly where over-optimistic roadmaps go wrong. It works far beyond product features: prioritising experiments, marketing campaigns, process improvements, even which bugs to fix. Keep the Impact scale consistent across ideas or the scores stop being comparable. All computed on your device.
Frequently asked questions
What does RICE stand for?
Reach, Impact, Confidence and Effort. The score is Reach × Impact × Confidence ÷ Effort, three benefits divided by the cost, giving one number to rank ideas by. It was created by Intercom for roadmap prioritisation.
What scale should Impact use?
A small consistent scale, commonly 3 = massive, 2 = high, 1 = medium, 0.5 = low, 0.25 = minimal. The exact numbers matter less than using the same scale for every idea so the scores compare fairly.
Why include Confidence?
To discount ideas built on optimism rather than evidence. A high-reach, high-impact idea you're only 50% sure about scores lower than a solid one, which stops guesswork dominating the roadmap.
Is RICE only for product features?
No. It works for any set of options with measurable inputs: experiments, campaigns, process improvements, hiring, bug-fix order. Anywhere you need objective prioritisation.
What units should Reach and Effort use?
Reach is a count of people (or accounts, or events) over a fixed period, say "users per quarter", used consistently for every idea. Effort is the total work, most often measured in person-months (one person for one month = 1). Keep the same period and units across all ideas or the scores stop comparing fairly.
How do I turn Confidence into a number?
Use it as a percentage that discounts the score: 100% for claims backed by data, around 80% for a reasonable estimate, and 50% for an educated guess. Multiplying by Confidence pulls speculative, "moonshot" ideas down below solid, evidence-backed ones of similar size, which is the whole point of including it.
