RICE & ICE Prioritization Calculator
Which idea should you build first? Score your features with RICE or ICE, see them ranked instantly, paste a backlog from a spreadsheet and export the result as CSV.
Free for everyone to use, no sign-up. Nothing you type leaves your browser.
Paste from a spreadsheet or CSV
One idea per line, columns in this order: . Tab-separated (copied from Excel or Google Sheets) or comma-separated. A header row is skipped, and for RICE the impact can be a word (minimal, low, medium, high, massive). This replaces the rows of the current method.
Ranking
How to use it
List your ideas, one per row, then score each one. The ranking updates as you type, and ideas with equal scores share a rank. The scores only mean something relative to each other, so score every idea with the same assumptions and the same time frame.
Key ideas explained
Reach: how many people the idea touches in a set period, for example customers per quarter. Use real numbers from your analytics where you can.
Impact: how much it moves the goal for each person reached. On the RICE scale: 3 massive, 2 high, 1 medium, 0.5 low, 0.25 minimal.
Confidence: how sure you are about your reach and impact numbers. Solid data is 100%, a reasonable guess 80%, a gut feeling 50% or less. It lowers the score of ideas you are unsure about.
Effort: the total work, in person-months, from everyone involved (product, design, engineering). Ease (ICE) is the opposite: 10 means trivially easy.
Worked example
"Dark mode" reaches 5,000 people, has low impact (0.5), you are 90% sure, and takes 1 person-month: 5,000 × 0.5 × 0.9 ÷ 1 = 2,250. "SSO for enterprise" reaches only 300 people but has massive impact (3), 70% confidence and 6 person-months: 300 × 3 × 0.7 ÷ 6 = 105. Cheap, broad ideas can beat big, important ones; that is a prompt to discuss, not an order.
Before you trust a ranking: are the reach numbers from data rather than opinion? Did everyone use the same impact scale? Are dependencies, deadlines and strategy considered outside the score? A framework supports the conversation; it does not replace judgement.
Methodology
Assumptions and limits: both frameworks turn estimates into a single number, so the ranking is only as good as the estimates. RICE scores are not comparable with ICE scores, nor across different time frames for reach. Ties share a rank and keep the order in which you entered them. In exports, text that starts with =, +, - or @ is prefixed with an apostrophe so spreadsheet software does not run it as a formula.
Frequently asked questions
What is the RICE scoring framework?
RICE scores an idea as Reach times Impact times Confidence divided by Effort. Reach is how many people it affects in a period, Impact how much it moves each of them, Confidence how sure you are of those estimates, and Effort the person-months it takes. The higher the score, the more value per unit of effort.
What is the difference between RICE and ICE?
ICE multiplies Impact, Confidence and Ease, each scored from 1 to 10. It is faster because it needs no reach numbers or effort estimates, but it is more subjective. RICE uses real numbers for reach and effort, so it suits teams that have that data.
How do I choose the Impact value in RICE?
The usual scale is 3 for massive, 2 for high, 1 for medium, 0.5 for low and 0.25 for minimal impact per person reached. Pick the value that matches the effect on your main goal, and apply the same scale to every idea.
What is a good RICE score?
There is no universal good score: the numbers only mean something relative to the other ideas you score with the same assumptions. Use RICE to rank ideas against each other, not to judge one in isolation.
Can I export my prioritized list?
Yes. Download the ranking as a CSV file or copy it and paste it into a spreadsheet. You can also paste rows from a spreadsheet into the tool to score them.
