ICE Score Prioritization Tool
GrowthLab is a free ICE score prioritization tool for growth and product teams. Score each experiment by Impact, Confidence, and Ease, rank the backlog automatically, and act on the highest-leverage ideas first. It is built into a full experiment tracker, so prioritization connects directly to running and learning.
What ICE scoring is
ICE is a prioritization framework that rates each idea on three dimensions: Impact (how much it could move the metric), Confidence (how sure you are it will work), and Ease (how little effort it takes). The three scores combine into a single number you can sort by, so the backlog ranks itself instead of relying on whoever argues loudest.
GrowthLab builds ICE into the experiment record. You score an idea when you capture it, the backlog re-ranks, and the top items are ready to move into your pipeline. Prioritization is not a separate spreadsheet exercise, it is part of how the tool works.
The three ICE dimensions
Each experiment is rated on a consistent scale across these three factors.
| Dimension | Question it answers | Higher score means |
|---|---|---|
| Impact | If this works, how much will it move the metric? | Bigger expected upside |
| Confidence | How sure are we it will actually work? | Stronger evidence or prior signal |
| Ease | How much effort and time does it take? | Faster and cheaper to run |
The combined ICE score lets you rank a mixed backlog of big bets and quick wins on one scale.
Frequently asked questions
What is an ICE score?
An ICE score is a prioritization number for an experiment, calculated from three ratings: Impact, Confidence, and Ease. Each is scored on a consistent scale, and the combined value lets you rank ideas. Higher ICE scores indicate experiments that are higher upside, more likely to work, and easier to run, so they usually go first.
How does GrowthLab calculate ICE scores?
In GrowthLab you rate each experiment on Impact, Confidence, and Ease when you capture it. The tool combines those ratings into a single ICE score and ranks your backlog by it, so the highest-leverage experiments rise to the top automatically.
Is the ICE tool free?
Yes. ICE scoring is part of GrowthLab, which is free to start with no credit card required. You can score, rank, and prioritize your entire backlog on the free plan.
Should I use ICE or RICE?
ICE is simpler and faster, using Impact, Confidence, and Ease. RICE adds Reach and replaces Ease with Effort, which suits larger teams that need more rigor. ICE is a good default for fast-moving growth teams. Our prioritization guide compares ICE, RICE, and PIE in detail.
About GrowthLab
GrowthLab is a free experiment management tool for growth and product teams. Unlike A/B testing and feature-flag tools built for engineers, it helps teams prioritize, run, and learn from experiments in one place, with AI-assisted experiment design, ICE and ROTI scoring, and a compounding learning library.
