RICE Feature Prioritization Calculator
Compare product ideas with a consistent reach, impact, confidence and effort rubric. The score helps a discussion; it does not replace judgment about safety, strategy or dependencies.
How the calculation works
RICE score = reach × impact × confidence fraction ÷ effort. Use one reach period and person-months of effort for every feature. The impact scale commonly uses 0.25, 0.5, 1, 2 and 3. Scores with equal values keep their original order.
Worked example
A feature with reach 1,000, impact 2, confidence 80% and effort 4 person-months scores 400. A high score is only as credible as the evidence behind its inputs.
Read the limits before using the result
Dependencies, urgent defects, obligations and high-consequence risks need separate treatment. Avoid false precision; compare conservative estimates and discuss why scores change.
