RICE score calculator
Compare features using reach, impact, confidence and effort. Keep the assumptions visible, then decide what deserves the work.
Compare the work, not just the idea.
RICE = reach × impact × (confidence ÷ 100) ÷ effort. Use the same reach period and effort unit for every feature. Numeric starting values are editable assumptions.
Your ranked backlog
Name a feature to start scoring. 1 incomplete row not ranked.
Equal scores keep their added order. Export requires every row to be valid. Formula-like feature names are escaped for spreadsheets. Scores support a discussion; they do not account for every dependency or commitment. Everything stays in this browser.
Give the backlog a common language.
A request can sound urgent without explaining how many people it helps or how much work it needs. Put those assumptions beside each other, then use the score to make the next discussion more concrete.
Use the score. Keep your judgement.
A high score does not remove a dependency, a contractual commitment or an important maintenance task. Use the ranking to ask better questions, then choose the release that makes sense for the product and the people using it.
How to use it
Define the comparison
Use one reach period, impact scale and effort unit for every feature. Replace the starting assumptions with your own estimates.
Review the ranking
Add or remove features and compare scores. Test the uncertain inputs rather than treating estimates as facts.
Take it into the team
Export the complete backlog, discuss constraints that the score cannot capture and agree what to work on next.
Know what the number is saying.
A fictional feature reaching 300 people, with impact 2, confidence 80% and effort 2, scores 240. Doubling the effort halves the score; lowering confidence also lowers the result. The arithmetic is simple. The quality of the comparison depends on the estimates you put into it.

A backlog needs someone to own the delivery.
My ongoing Telecoms World work includes website maintenance, script management, HubSpot forms and the connected number-ordering journey. The job involves keeping existing systems dependable while deciding which improvements to ship next.
RICE calculator questions
RICE score = reach × impact × confidence ÷ effort. This calculator accepts confidence as a percentage, so it divides that input by 100 before calculating. For example, 300 × 2 × 0.8 ÷ 2 = 240.
Reach is how many people or events the feature affects in a defined period. Impact is the effect on each person. Confidence reflects the evidence behind the estimates. Effort is the combined work required, using one consistent unit across the backlog.
The original Intercom scale uses 3 for massive impact, 2 for high, 1 for medium, 0.5 for low and 0.25 for minimal. This tool accepts values from 0 to 3. Keep the scale consistent between features.
No. They are editable assumptions. Feature names begin empty. An explicit example action fills a fictional backlog so you can see how the tool works.
The formula divides by effort, so zero cannot produce a valid comparison. This tool requires at least 0.01 and excludes invalid rows from the ranking until you fix them.
Equal scores keep their original added order. Incomplete rows remain in the editor but are not ranked. Export stays disabled until every row is valid, so unfinished work is not silently omitted.
Yes. Export includes the selected sort order, feature names, all four inputs and the calculated score. Risky text is prefixed with a tab inside its quoted CSV cell to help prevent formula execution in Excel. This changes those text values; spreadsheet behaviour can vary. No backlog is uploaded or saved after you leave.
