Show the math

Add up compute, storage and data-transfer-out, then scale the monthly total to a year:

monthly = rate × instances × hours + storage + egress

A cloud month is usually billed as 730 hours. This is an on-demand estimate, reserved instances, savings plans, free tiers and inter-region transfer can change the bill a lot. Calculated entirely in your browser.

What this does

A cloud cost calculator estimates the monthly and annual cost of cloud instances, storage and data egress from their rates.

How to use it

  1. Enter the hourly rate and instance count.
  2. Enter storage GB and the per-GB price.
  3. Enter egress GB and price.
  4. Read the monthly and yearly total.

How it works

A month bills as 730 hours (8,760 ÷ 12). It is an on-demand estimate; reserved plans, free tiers and request charges can move the real bill.

monthly = rate × instances × 730 + storage + egress

Understanding your result

This is an on-demand estimate at 730 hours a month, so it is the ceiling, not the bill: reserved instances, savings plans, free tiers, and spot capacity can cut it substantially, while request charges, snapshots, and especially data egress can add costs this misses. Use it to compare options, then watch egress, which is the line that most often surprises.

Example

One instance at $0.10/hr runs about $73 a month before storage and egress.

Frequently asked questions

How is the monthly cost calculated?

Compute is the hourly rate × number of instances × hours per month; storage is GB × the per-GB price; egress is GB out × the per-GB price. The three are added for the monthly total, which is multiplied by 12 for the year.

Why 730 hours a month?

Cloud providers bill a month as 730 hours, the 8,760 hours in a year divided by 12. A continuously running instance therefore accrues about 730 hours of charges each month.

Is this exact?

It is an on-demand estimate. Reserved instances, savings plans, free tiers, request charges and cross-region transfer can move the real bill up or down, so treat it as a starting point.
