Cash on cash return measures the annual pre tax cash flow a property produces against the actual cash an investor put in. Unlike cap rate, which ignores financing, cash on cash reflects the loan, so it shows the real yield on your equity after debt service.
The cash invested includes the down payment, closing costs, and any upfront capital improvements. The cash flow is what remains after operating expenses and debt service. Leverage magnifies the result: cheap debt can lift cash on cash well above the cap rate, while expensive debt can drag it below.
Cash on cash is a single year snapshot and does not account for appreciation, principal paydown, or the eventual sale. Investors pair it with total return measures like internal rate of return to judge a deal over its full hold.
