Spreadsheets, all the way. Most spreadsheet (Excel, LibreOffice etc...) will have a function that gives you monthly repayments based on mortgage type, nominal, interest rates, number of repayment etc... It makes comparing upfront costs & amortised costs very easy.
Thanks, I hadn’t thought to look for that. I’ve been using bank-supplied info sheets and the excel compound interest & regular payment function to work out capital & interest paid.
Main problem was distilling that into quantifiable VFM, hence ratio of total cost to capital repaid.
