Cash-on-cash return

Cash-on-cash return is annual pre-tax cash flow divided by the total cash you actually put into the deal — down payment, closing costs and rehab. It answers a narrow question well: what does this investment pay me in year one on the money I committed? It ignores principal paydown, appreciation and tax benefits entirely.

Cash-on-cash = annual pre-tax cash flow ÷ total cash invested

Worked example

$3,841 of cash flow on $80,875 invested ($66,250 down + $6,625 closing + $8,000 rehab) is a 4.75% cash-on-cash return.

Rental metric examples use the default $265,000 duplex at $2,650 monthly rent, 25% down and 6.75% over 30 years. Strategy and tax examples use the assumptions stated above rather than that rental deal.

The mistake to avoid

Leaving closing costs and rehab out of the denominator. Using only the down payment inflates the number by roughly 20% on a typical deal, and it is the most common way a marketing pro forma flatters itself.

Where this is calculated

The cash on cash return calculator computes this from your own numbers and shows the arithmetic expanded. Annual pre-tax cash flow over every dollar of cash you put in — down payment, closing costs and rehab.
