Check what a calculation means

Pricing depends on your costs, time, fees and target. The pricing calculator documents its formulas with a worked example. A profit margin on the selling price is different from a markup on cost: check the meaning of percentages before comparing scenarios. You remain responsible for your inputs and assumptions.

Back up your records

Tracking tools operate separately. Depending on the app, exports can preserve rows or reopen a saved scenario. Check the available options on the product page and keep a backup outside the browser. A standalone HTML application is not a service that synchronises between devices.
