Rates shown are us-east-1 Linux On-Demand. Other regions are applied as an approximate multiplier in the results.
Who This Tool Is For
Cloud engineers, architects, and FinOps leads sizing EC2 fleets or sanity-checking a quote. If you're deciding between On-Demand, Spot, and Reserved Instances — or just want a quick monthly number before opening the AWS Pricing Calculator — this gives you the full picture in three clicks.
Why We Built This Tool
The most common cost question on any AWS engagement is 'what will these instances actually cost?' — and the answer changes dramatically with the pricing model. The AWS console is accurate but slow to navigate across instance types and commitment terms. We built this to show On-Demand, Spot, and 1-/3-year Reserved side-by-side from one screen, using the same us-east-1 list prices we model in real client cost reviews.
What Problem It Solves
- Commitment math. See the dollar gap between On-Demand and a 1- or 3-year Reserved Instance before you commit.
- Spot savings sizing. Quantify how much a fault-tolerant workload could save on Spot.
- Fleet budgeting. Multiply by instance count and real run-hours to get a defensible monthly forecast.
- Region sticker shock. See how much São Paulo or Tokyo adds over us-east-1 before you deploy there.
Pair this with our cloud cost optimization engagement to model Savings Plans and right-sizing against your actual usage.
Frequently Asked Questions
Where do these prices come from?
On-Demand rates are AWS published us-east-1 Linux list prices (pricing as of June 2026). Other regions apply an approximate multiplier. Spot and Reserved figures are modeled from standard discount ratios (Spot ≈ 70% off, 1-year Standard No Upfront ≈ 40% off, 3-year ≈ 60% off) — actual Spot prices fluctuate and exact RI rates vary by instance family.
Why is the month 730 hours, not 720?
AWS bills per second and uses 730 hours as the standard average month (365 days × 24 ÷ 12). A 24/7 instance in a 31-day month is 744 hours. We default to 730 so estimates match the AWS Pricing Calculator; change it to model business-hours-only or part-time usage.
Does this include EBS, data transfer, or other costs?
No — this calculator covers the EC2 compute (instance hours) only. EBS volumes, snapshots, data transfer out, Elastic IPs, and load balancers are billed separately. For storage and IOPS, use our IOPS Cost Calculator.
How does Windows pricing work?
Windows instances add a per-vCPU license fee on top of the Linux compute rate (License Included). We model this at roughly $0.046/vCPU-hour, which matches AWS published Windows On-Demand rates closely for general and compute-optimized families. Bring-Your-Own-License (BYOL) on Dedicated Hosts is priced differently.
Should I buy Reserved Instances or a Savings Plan?
For most teams a Compute Savings Plan beats Standard RIs: it delivers similar discounts but stays flexible across instance family, size, OS, and region. Standard RIs only win when you want the maximum discount on a very stable, specific instance type. Either way, right-size first — committing to over-provisioned instances locks in waste.
How accurate is this estimate?
On-Demand totals match the AWS Pricing Calculator within a cent for the listed instance types in us-east-1. Spot and Reserved are directional estimates based on typical discount ranges — use them to compare models, then confirm exact Reserved rates and live Spot prices in the AWS console before committing.
