What is in your AWS bill?

Load an export from Cost Explorer. I show the monthly totals, the split into the calculator’s categories, the 10 largest items and the usual savings signals. The file never leaves your browser.

Choose files

Cost Explorer, Cost and Usage Report or FOCUS, as CSV or .csv.gz. You can load several files at once.

The file never leaves your browser. A script on this page reads it, on your computer. I send nothing and store nothing: close the tab and the result is gone. You can check this in your browser’s developer tools, on the Network tab.

Where to get the file

In the AWS console, open Billing and Cost Management, then Cost Explorer.
Set the last 3–6 full months and Monthly granularity.
Group by Service. Grouping by Usage type shows more: NAT Gateway, snapshots, instance types.
Click Download as CSV and load the file here.

Have a Cost and Usage Report or FOCUS export from Data Exports? Download its .csv.gz files from S3 and load all parts of the month here at once, without unpacking them. Take each month from one folder: with Create new data export file, AWS writes every refresh to a folder of its own. If the report has the Savings Plans and reservation columns, I also show how they are used.

No file to hand?

A sample Cost Explorer export. Sample data: the company, the account and the amounts do not come from any client.

Savings signals

Only what the file shows. Each signal is a question to check in the account, not a ready-made saving.

What would this cost outside AWS?

The numbers travel in the address, in the part after the # sign, which the browser does not send to the server.

Move these numbers to the calculator AWS cost audit from EUR 690

The result is an estimate based on the file alone, not an offer. It is no substitute for the audit: a bill does not show how loaded your servers are, or which resources you really need. That is what I check in the audit, with read-only access to the account.

Send me your AWS bill

Within 2 business days I will reply with 3 concrete observations.

I do not need access to the account. A PDF invoice from the console or a Cost Explorer export for the last 3 months is enough.

Only I read the file, and I do not paste it into AI tools. I delete it when you ask, and after 12 months at the latest.

The analysis on this page does not send the file. If you want me to look at it, attach it to the e-mail.

What I count, and what I leave out

I work out the average from full months. The current month, and any month with days missing, I show but do not average.
I leave tax (Tax), credits and refunds out of the totals, because the calculator compares the net prices of the services alone.
I use the “Service total” row and the “Total costs” column from Cost Explorer only as a check: I make sure the lines add up to them.
I put the lines into the same five categories as the calculator. I count EC2-Other as data and backups, because it is mostly EBS volumes and snapshots, although AWS also puts NAT Gateway and traffic between zones in it.
The savings signals are rules from my audits, checked against the numbers in the file: the share of traffic and NAT Gateway, snapshots, gp2 volumes, IP addresses with no instance, EC2 and RDS without Savings Plans, CloudWatch growth and older instance generations. Some only show in a file grouped by usage type.
In a Cost and Usage Report or a FOCUS export I also split NAT Gateway into hours and processed data, show data transfer within the region (mostly traffic between zones) on its own, and work out how much of your Savings Plans and reservations is used. I give no saving figure for these: the file does not show what the account could do without.
I add several files together when they are the same kind of export, with the same grouping and currency. Two exports for the same month, or the same file loaded twice, for example as .csv and .csv.gz, would count it twice, so then I stop and say so. Repeated lines of a CUR, with the same line item id, count once.
The separator can be a comma, a semicolon or a tab, and the decimal mark a point or a comma.
