AWS Cost Estimator (Lite)

Sketch a rough monthly AWS bill in seconds. Add EC2, S3, RDS, and data transfer line items with editable rates, and see monthly and yearly totals update live — all in your browser, nothing uploaded.

📖 How it works & FAQ

AWS line items — edit quantities and rates (defaults are typical US East on-demand rates)

Rough planning estimate only — real AWS bills also depend on region, instance type, tiered and reserved pricing, the free tier, and dozens of other services. This is not an official AWS quote.

A quick, back-of-the-envelope AWS bill

The official AWS pricing calculator is powerful but slow to set up when all you want is a ballpark. This lite estimator covers the four line items that dominate most small-to-medium bills: EC2 compute, RDS databases, S3 storage, and data transfer out. Each row is simply quantity × rate — instance hours times an hourly price, or gigabytes times a per-GB price — and every rate is an editable input, pre-filled with typical US East on-demand defaults. Change any number and the monthly total, yearly projection, and per-service breakdown update instantly. Everything runs in your browser; no account, no upload, and your numbers never leave your device.

Estimates only, not professional, financial, or tax advice; AWS rates & fees vary by region and change over time.

How to use it

Review the four starter rows: EC2, S3, data transfer, and RDS. Remove any service you do not use.
Set the quantity for each row — hours per month for EC2 and RDS (730 hours is a full month of 24/7 uptime), or gigabytes for S3 and transfer.
Replace the default rates with the real prices for your instance type and region, straight from the AWS pricing pages.
Click “Add line item” for extra instances or buckets, and read the monthly and yearly totals plus each service’s share of the bill.

FAQ

Where do the default rates come from?: They mirror common US East on-demand prices — a t3.medium-class EC2 instance, standard S3 storage, internet data transfer out, and a small RDS instance. They are placeholders: always paste in the current rate for your exact configuration.
Why does my real AWS bill differ from the estimate?: AWS pricing includes tiered rates, free-tier allowances, reserved and spot discounts, EBS volumes, requests, IOPS, and regional differences. This tool intentionally skips those to stay fast, so treat the result as a rough floor, not a quote.
How do I model multiple servers?: Add one line item per instance, or multiply: three identical servers running 24/7 is one EC2 row with 2,190 hours.
Is 730 hours the right monthly number?: Yes — 8,760 hours per year divided by 12 is 730, the convention AWS itself uses for always-on resources.
