Property Investment Calculator

Enter a rental's price, loan, income and costs into a property investment calculator and it returns the usual set of return figures. Cash on cash return tends to lead that list, with cap rate, gross rent multiplier, NPV and IRR close behind. This site's calculator is that tool centered on cash on cash.

Each output answers a different question. Cap rate and GRM describe the property before financing. Cash on cash brings the mortgage into the math and shows one year's return on the cash you put in. NPV and IRR go further, covering every year you hold the property plus the eventual sale.

The calculator here builds the full income statement, subtracts the mortgage, divides by cash invested, and then solves backwards for the rent and the maximum price that hit a target return. It shows cap rate and the all-cash return beside the leveraged one so the effect of financing is visible. For multi-year decisions, the same cash flow feeds an IRR.
