try it properly

This is the real engine, on a real plan. Edit anything.

Nothing here is saved, and this page cannot save. It runs on an in-memory copy, so when you close the tab the changes are gone. Exporting, forking a scenario and starting a plan of your own are what the paid app adds — we are telling you now rather than after you have typed in your salary.

Worth doing while you are here: put your own spending in the box below and watch What actually moves it re-rank. A percentage is not why anyone changes their life — seeing which single lever is short is.
