Question 1

Are the spreadsheet calculators free to use?

Accepted Answer

Yes. Every one of the 11 models runs free in your browser with live results, a free CSV export, and a 1-sheet Excel sample. Pro unlocks the full multi-sheet workbooks and the all-models master export.

Question 2

Can I use my own currency?

Accepted Answer

Yes. Pick your country from the selector and every amount - inputs, results, charts and the exported workbook - displays in your local currency. Baseline defaults are converted automatically.

Question 3

Do the downloaded Excel files contain real formulas?

Accepted Answer

Yes. The exported .xlsx workbooks use live Excel formulas, so when you change an assumption cell the whole workbook recalculates in Excel 2016+ or Google Sheets.

Question 4

Can I save and compare different scenarios?

Accepted Answer

Yes. Save your inputs as named scenarios and compare them side by side against your current numbers. The free plan saves two scenarios per model; Pro is unlimited and adds a comparison CSV export.

Question 5

Is my financial data private?

Accepted Answer

Yes. Everything runs locally in your browser and your numbers are stored only on your device (localStorage). Nothing is uploaded to a server.
