The formula is on the page
Every calculator spells out the math it runs, so you can check it or redo it in a spreadsheet.
A worked example
Each page walks through one deal, computed by the same code as the calculator.
Assumptions you can change
Inputs start from common assumptions (5% interest, 30-year amortization, renovation at 10% of the price). The after-repair value and rent are yours to estimate.
