Break Even Calculators

A few years ago PMQ had some break-even ‘calculators’ (they were actually excel spreadsheets) available online. The links are coming up dead now. Does anyone out there have a calculator/spreadsheet or even a manual form they like using?

Theres one here, 6th from the bottom.

Thanks!

Next question…
if we have multiple loans and even (gasp!) credit card debt, can this template handle that? If not, any magic formulas for converting a bunch of different amounts & rates into one set of ballpark figures to plug into this template?
