Schedule savings calculator
Pick an instance type and region, then set the hours per week it actually needs to be on — dev boxes, staging, batch workloads. This estimates what you'd pay on that schedule versus running the same instance around the clock. List price, no signup required.
This is a list-price estimate. The free Idle Audit measures your real CloudWatch/Monitoring metrics.
Run a free idle auditThis calculator estimates the monthly cost of one instance type at whatever schedule you set, next to what it would cost left on around the clock. Move the slider or pick a preset to see how many hours a week actually matter for the workload — a batch job, a dev box, anything that doesn't need to run nonstop — and watch both figures move together.
It runs on a public snapshot of on-demand list prices, not a live read of your account, so treat the output as a starting estimate rather than a bill. Nothing you enter is saved or sent anywhere. For a number based on how the instance is actually used, the free idle audit measures the real metrics instead of assuming a schedule.
Prices are on-demand list price and exclude storage, network, data transfer, and any negotiated or volume discounts. Actual bills vary by usage and account-level pricing. Prices as of 2026-07-20.
