Common Scenarios & Troubleshooting
This tool is built for the moment you need a quick, accurate answer without opening a spreadsheet.
Note on errors: the most common slip-up here is rounding the wrong number, or forgetting a recurring cost that quietly changes the real total. If that happens, double-check your input rather than the tool — the calculation itself runs the same way every time.
Your data stays private. Everything you type runs locally in your own browser tab. Nothing is uploaded, logged, or stored on a server — close the tab and it's gone.
Behind the Scenes: The Processing Logic
