Cash-on-cash return: formula and what counts as good

Financed investors don't care what a property earns in theory. They care what their actual dollars earn. Cash-on-cash return is the number that answers them.

This guide covers the formula, a worked example you can follow line by line, what a good cash-on-cash return looks like, and how leverage can make the same property show two different returns.

What is cash-on-cash return?

Cash-on-cash return is a property's annual pre-tax cash flow divided by the total cash you invested, expressed as a percentage. Cash-on-cash return measures what the money you actually put into a deal earns each year, after all expenses and the mortgage are paid.

The metric exists because most investors don't buy with cash. A cap rate describes the property as if financing didn't exist. Cash-on-cash describes your deal: your down payment, your loan, your leftover cash flow. Two buyers can purchase identical buildings and earn different cash-on-cash returns purely because they financed differently.

How do you calculate cash-on-cash return?

To calculate cash-on-cash return, divide the property's annual pre-tax cash flow by the total cash invested, then multiply by 100.

Cash-on-cash return = (annual pre-tax cash flow ÷ total cash invested) × 100

Here's the same deal from our ROI guide, a $300,000 rental bought with 20% down:

1. Total cash invested: $60,000 down payment + $6,000 closing costs + $4,000 light renovation = $70,000.
2. Annual cash flow: $28,800 in rent, minus $8,800 in operating expenses and reserves, minus $14,000 in mortgage payments = $6,000.
3. Divide: $6,000 ÷ $70,000 = 0.086, an 8.6% cash-on-cash return.

Every input is a real number you can pull from a listing, a lender quote, and an expense estimate. That's the appeal: no projections about appreciation, just this year's cash against your cash.

What is a good cash-on-cash return?

According to BiggerPockets, investors commonly cite 8% to 12% as a solid cash-on-cash return for a rental property, though the right target depends on the market and the investor's goals. Treat the range as a reference point, not a rule.

Context moves the goalposts. In appreciation-heavy markets, investors accept lower cash-on-cash because they're betting on equity growth. Cash-flow investors in flatter markets demand the higher end. And a return that looks thin today can climb as rents rise against a fixed mortgage payment, which is why year-one cash-on-cash is a snapshot, not the whole movie.

Is cash-on-cash return the same as ROI?

No. Cash-on-cash return counts only this year's pre-tax cash flow, while ROI can also fold in appreciation, loan paydown, and tax effects depending on how it's measured. Cash-on-cash is the strictest, most conservative lens on a financed deal.

In practice the two start from the same math, and on a simple year-one analysis they can land on the same number. The difference shows up over time: sell after five years of appreciation and principal paydown, and the deal's full ROI can be far higher than any single year's cash-on-cash suggested. Quote cash-on-cash for the "what do I earn while I hold it?" question and ROI for "what did this deal make me overall?"

How does leverage change cash-on-cash return?

Leverage usually raises the cash-on-cash percentage while lowering the dollar profit, because you're putting in less of your own money. Same property, two financing choices:

All cash20% downCash invested$300,000$70,000Annual cash flow$20,000$6,000Cash-on-cash returnAbout 6.7%8.6%

The financed buyer earns a third of the dollars at a higher rate on their cash. Neither answer is wrong. But leverage cuts both ways: add a vacancy or a rate jump and the financed deal's thin $6,000 cushion can go negative fast, while the cash buyer just earns less. Cash-on-cash makes that risk trade visible before you're in it.

What does cash-on-cash return leave out?

Cash-on-cash return ignores appreciation, principal paydown, tax benefits, and any expense you didn't put in the projection. It's a one-year cash snapshot, and that's both its strength and its blind spot.

The two failure modes to watch: treating year one as forever, and feeding it dishonest inputs. Skip the vacancy reserve or the management fee and the formula happily returns a beautiful number that will never survive contact with a real tenant. The net operating income discipline, every expense on the table, is what keeps cash-on-cash honest.

How do agents use cash-on-cash with investor clients?

Agents use cash-on-cash to compare financing scenarios on the same property and to match deals to what a specific client's cash needs to earn. It's the final number in the USRT Three-Number Deal Check: the gross rent multiplier screens the list, cap rate confirms the property, and the cash-side math closes the client.

The conversation is simple: "At 20% down with your lender's quote, this earns about 8.6% on your cash in year one. Here's the line-by-line." Bring that to a meeting with investor clients and you're not selling a house, you're presenting an investment. That's the agent they call for the next five deals.

The takeaway

Cash-on-cash return is annual pre-tax cash flow divided by the cash you invested, and it's the number financed investors feel in their bank account. Keep the inputs honest, read it alongside cap rate instead of instead of it, and remember it's a year-one snapshot of a multi-year bet. Master this one and you speak fluent investor.
