# Margin Analyzer

See which customers are profitable and which are hurting your margins.
Upload your own CSV of customer revenue and cost data (up to 10 MB), or
load the sample analysis to see how it works. Analysis runs client-side;
your CSV stays in the browser.

The report shows customer profitability, margin distribution, and date
filters for the last 30 days, 90 days, or 12 months.

This is a free tool, not the product. The
[Tanso engine](https://tansohq.com/product.md) computes the same margin view
continuously by stamping cost (tokens, model, provider) on every metered
event next to what was billed.
