Fernsheet makes budget, debt payoff, savings and UK Self Assessment spreadsheets for Microsoft Excel. You type in the yellow cells and every total, chart and date works itself out.
Every template is tested before release against an independent calculation, including unusual entries. Formulas are locked in Excel, so a stray keystroke cannot wipe a total, and you can unprotect any tab with no password.
Each file comes with a Start Here tab and a PDF quick start guide. If anything does not work as described, send us a message on Etsy and we will fix it.
Our templates are designed by us with the help of digital tools, including AI assistance. More at fernsheet.com
