FAQ
What does this tool tell you?
The EC2 Cost Calculator computes on-demand, reserved instance, and effective hourly pricing for any AWS EC2 instance type across regions, using embedded AWS public pricing data.
What affects the result most?
Instance family × vCPU × memory × region → on-demand hourly and monthly cost. On-demand vs 1-year vs 3-year reserved pricing comparison with break-even months. Linux vs Windows pricing differential for same instance class.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
