How to use the AWS EC2 Cost Calculator
- 1. Choose the instanceType, how many, and hours per day and days per month.
- 2. Add storage and trafficEBS gp3 storage per instance and data sent out to the internet.
- 3. CalculateSee the monthly and yearly cost in rupees and dollars, with each part explained.
What makes up an EC2 bill
An EC2 server is billed by the second while it runs, at its hourly rate. On top come the EBS volume (its disk, billed per GB-month even when the server is stopped) and data transfer out to the internet, where the first 100 GB a month across your account are free. Customers billed by AWS India pay 18% GST on top. The calculator uses Asia Pacific (Mumbai) prices for 13 common instance types, from t3.micro to m7i.xlarge, including the cheaper Graviton (Arm) t4g and m7g types. Prices are on-demand list prices checked on 10 November 2026, and every rate is editable, because cloud prices change. Confirm them on the provider's pricing page before you budget.
Savings Plans and reserved instances cut the hourly rate if you commit for one or three years; enter the discount AWS quotes you. Turning servers off outside working hours often saves even more.
Worked example
Two t3.medium servers (2 vCPU, 4 GiB each) running all month (730 hours) at $0.0448 an hour cost $65.41. Add 30 GB of gp3 storage each ($5.47) and 200 GB of data out, of which 100 GB is charged ($10.93), and the total is $81.81, or ₹9,074 a month including ₹1,384 GST at ₹94 per dollar. That's about ₹1.09 lakh a year.
Ways to cut the bill
- Use Graviton types (t4g, m7g) where your software supports Arm; in Mumbai they're much cheaper per hour.
- Stop development servers at night and on weekends.
- Release Elastic IPs you aren't using; public IPv4 addresses are charged hourly.
