How the math works
Eligible monthly spend is on-demand spend times coverage. The discount applies to that eligible portion only. Uncovered spend stays at on-demand rates and is excluded from the savings.
Total commitment is eligible monthly spend times the discounted rate, multiplied by 12 for 1-year or 36 for 3-year. The upfront portion is 50 percent for partial and 100 percent for all upfront. Break-even compares cumulative savings to upfront paid.
The defaults assume Compute Savings Plan rates published by AWS as of 2026. Reserved Instance pricing differs and is not covered by this calculator.
Numbers look promising. Now check whether your actual AWS bill already has unconverted savings plans, expired RIs, or workloads that would change the coverage assumption. Cloud Horizon runs the audit free for 14 days, read-only access, no card.
Frequently asked
How accurate are the default discount percentages?
The defaults reflect typical AWS Compute Savings Plan rates as of 2026: roughly 17% for 1-year no-upfront, 28% for 1-year all-upfront, 36% for 3-year no-upfront, and 54% for 3-year all-upfront. Real rates vary by region, instance family, and OS. Override the discount field with the rate from your AWS console for accurate output.
What does coverage mean?
Coverage is the share of your eligible compute spend the Savings Plan applies to. A $10,000 per month on-demand baseline at 80 percent coverage means $8,000 per month gets the discount and the remaining $2,000 stays at on-demand rates. Most teams target 70 to 90 percent coverage to leave headroom for variable workloads.
Why is break-even month relevant for no-upfront?
For no-upfront and partial-upfront commitments the break-even is month one or two because the Savings Plan begins saving money immediately. For all-upfront the upfront fee creates a payback period. The calculator shows when cumulative savings exceed the upfront cost.
