About Ledgerline
Ledgerline makes small, honest tools for the money side of a small business: free calculators on this site, and spreadsheet templates for people who want to track the same numbers all year.
What we believe
- Show the formula. Every calculator explains exactly how it gets its number, with a worked example you can check by hand.
- Include the awkward fees. The fee or cost that gets left out is usually the one that turns profit into loss.
- Private by default. Calculations run in your browser. We do not ask for an email, set tracking cookies or store what you type.
- Plain files you own. Our templates are ordinary .xlsx files for Excel and Google Sheets. No subscription, no app to log into.
How the numbers are checked
The calculator math lives in one small script that is tested against hand-worked examples, and it uses the same formulas as our spreadsheet templates, which are recalculated and checked before release. Fee rates and tax rules change, so every rate is editable and each page shows when it was last reviewed.
