Why We Built This Tool
The answer changes dramatically with pricing model. This calculator shows On-Demand, Spot, and Reserved side-by-side from one screen.
What Problem It Solves
- Commitment math. See the dollar gap between On-Demand and 1-/3-year Reserved options.
- Spot risk visibility. Spot estimate now includes interruption band risk context.
- Fleet budgeting. Multiply by instance count and run-hours for a monthly forecast.
Pair this with our cloud cost optimization engagement.
Frequently Asked Questions
Where do these prices come from?
On-Demand rates are AWS published us-east-1 Linux list prices (pricing as of 2026-10-17). Spot figures are directional and weighted by interruption risk bands. Reserved values use standard planning discounts (1-year ≈ 40% off, 3-year ≈ 60% off).
Does this include EBS or data transfer?
No — this tool covers EC2 compute only. Use related tools for storage and network line items.
How accurate is this estimate?
On-Demand aligns closely with AWS Pricing Calculator. Spot and Reserved outputs are directional planning values.
Are Graviton5 and T8i instances included?
Yes. Graviton5 m9g / c9g / r9g list higher per hour than Graviton4 m8g / c8g / r8g (AWS quotes up to 25% better compute performance), so they win on price/performance, not hourly rate. T8i (Intel Xeon 6) is the T3 successor; at launch it is On-Demand only, with Spot and Savings Plans announced as coming soon, so treat Spot and Reserved figures for T8i as not yet purchasable.
