Cloud Cost Breakdown Calculator
A cloud bill is easier to act on once you can see which services make up most of it. This calculator adds your spend by service, such as compute, database and storage, and shows each one's share of the total. It is useful for CFOs, engineering managers and FinOps leads preparing a cost review or deciding where to look for savings first.

What this technology tool gives you
The output shows the total, then a table with each service, its amount and its percentage share. Paste it into a monthly spend review or a budget discussion; the service with the biggest share is usually where optimization effort pays back fastest.
What you enter
- Currency: USD, EUR or GBP
- Services: one row per service, with the service name and the amount spent
Worked example
The example has three services: Compute $1,800, Database $900 and Storage $300. The total is $3,000. Compute is 1,800 ÷ 3,000 = 60.0% of spend, Database 30.0% and Storage 10.0%. In a cost review, compute is where the first savings conversation would start.
How is each cloud service's share calculated?
Total = the sum of all service amounts, rounded to two decimals. Share = service amount ÷ total × 100, shown as a percentage with one decimal.
Each row needs a name and a non-negative amount. You can add as many services as you like. If every amount is zero, the share column shows a dash rather than dividing by zero. Shares are relative to the lines you entered, not to your full bill if you left services out.
Tips before you use the result
- Use the same period for every line, such as one billing month, or the shares will mislead.
- Include support plans, data transfer and marketplace fees as their own lines; they are easy to miss and can be large.
- Group small services into an Other line so the table stays readable in a meeting.
- Compare shares month over month; a service whose share grows faster than usage deserves a closer look.
Frequently asked questions
How do I break down my cloud bill by service?
Export the bill grouped by service from your provider's billing console, then enter each service and its amount here. The tool totals them and shows each service's percentage of the total, so you can see at a glance where most of the monthly spend goes.
Does it work for AWS, Azure and Google Cloud?
Yes, because it does not connect to any provider. You type the service names and amounts yourself, so you can use any provider or combine several in one table. It only adds up and divides the numbers you enter, nothing more.
Can I use euros or pounds?
Yes. Choose USD, EUR or GBP and the amounts and total are formatted in that currency. The tool does not convert currencies, so enter every amount in the same currency, converted beforehand if your bills come in more than one.
Where is my cost data kept?
It is stored in local storage in this browser only, with no account, so your figures remain private to your device and reload on your next visit. Nothing is sent to a server. Copy output or Print shares the result when you are ready.
