Questions
Frequently asked questions
Does it work in Google Sheets?
Yes. Open it in Microsoft Excel or import into Google Sheets — all formulas work. Minor visual formatting may differ.
Do I need accounting or spreadsheet skills?
No. If you can type a number into a cell, you can use it. You only edit the highlighted cells, and a built-in Guide explains every term.
Is this financial advice?
No. DealGauge tools are for education and planning only and are not financial, tax or investment advice. Always verify figures independently.
How do I receive the file?
Instantly. After checkout you get an immediate download link plus an email copy. Access is lifetime, including free updates.
What's your refund policy?
Because these are instant digital downloads, all sales are final — but the free calculator and the screenshots show exactly what you're getting before you buy.
