Interactive estimator
CI savings calculator
Estimate how much build time and CI spend remote caching can avoid each month. This model is client-side only and based on transparent assumptions.

Adjust these inputs to match your monorepo workflow.
Estimated monthly impact
- Monthly build minutes avoided
- 12,096
- Engineer hours saved
- 201.6
- Estimated monthly cost saved
- Add CI cost/minute to estimate
This output is an estimate. Real savings depend on actual cache hit rate, task distribution, and how often workflows can reuse prior outputs.
Assumptions used by this calculator
- Monthly build executions = developers x builds per developer per day x working days per month.
- Monthly build minutes avoided = monthly build executions x average build duration x expected cache hit ratio.
- Cost savings = avoided minutes x CI cost per minute (when provided).
