How to Calculate Cash-on-Cash Return on a Rental Property
The one return metric that tells you what a rental pays on the money you actually put in, worked through line by line.
Every other return metric answers a question about the property. Cash-on-cash return answers one about your money: what the deal pays, each year, on the cash you handed over at closing. This guide covers the formula, what belongs in the denominator, a worked example, targets by market, and the four mistakes that make a weak deal look strong.
The cash-on-cash return formula
Cash-on-cash return is annual pre-tax cash flow divided by the total cash you invested to acquire the property. Cash flow is what remains after every operating expense and the full mortgage payment.
Cash-on-cash return = Annual cash flow ÷ Total cash invested × 100
A property that produces $4,000 of cash flow a year on $50,000 invested returns 8%.
The metric is deliberately narrow. It ignores the equity the tenant builds by paying down your loan, the appreciation the property gains and the tax treatment of the income. That narrowness is the point: it isolates the one return you can spend this year.
Because financing sits inside the calculation, the same property produces a different cash-on-cash return for every buyer. A cash buyer, a 25%-down buyer and a 10%-down buyer will each get a different answer, which is why the metric is about you and your loan as much as the house.
What counts as cash invested
The denominator is every dollar you put in before the property starts paying you. Investors get the cash flow side roughly right and the cash invested side badly wrong, almost always by leaving things out.
| Include | Typical size | Leave out |
|---|---|---|
| Down payment | 20% to 25% of price | The loan amount |
| Buyer closing costs | 2% to 3% of price | Seller-paid credits you did not fund |
| Lender fees and discount points | 0% to 2% of loan | Future refinance costs |
| Repairs needed before the first tenant | $0 to $20,000+ | Repairs funded from later cash flow |
| Reserves funded at purchase | 3 to 6 months of expenses | Reserves you never actually set aside |
If a line was paid from your account between contract and first rent, it belongs in the denominator.
A worked example on a $185,000 rental
Take a three-bedroom single-family house bought for $185,000 with 25% down, financed at 6.75% on a 30-year loan, renting for $1,950 a month. It needs $5,000 of paint and flooring before the first tenant.
Add up the cash invested
Down payment $46,250, closing costs $4,600, initial repairs $5,000. Total cash invested: $55,850.Work out annual operating expenses
Vacancy at 5% of rent, property taxes $2,800, insurance $1,300, maintenance at 7%, management at 8%, capital expense reserve at 5%. On $23,400 of annual rent that is $9,950.Subtract expenses and the mortgage from rent
The $138,750 loan costs $900 a month in principal and interest, $10,799 a year. Rent less expenses less debt service is the annual cash flow.Divide by cash invested
Annual cash flow divided by $55,850 gives the cash-on-cash return.

What a good cash-on-cash return looks like
A good cash-on-cash return is one that beats what the same cash would earn elsewhere, adjusted for the work and risk of owning a rental. In 2026 that bar is set by money market yields near 4% to 5%, so a financed rental below that level is being bought for appreciation, not income.
| Market type | Examples | Typical range | Read it as |
|---|---|---|---|
| Cash flow markets | Cleveland, Memphis, Birmingham, Detroit | 8% to 12% | Income is the return; appreciation is a bonus |
| Balanced markets | Indianapolis, Kansas City, Columbus, San Antonio | 5% to 8% | Income covers the cost of ownership with modest growth |
| Appreciation markets | Austin, Tampa, Denver, most coastal metros | 2% to 5% | You are paid mostly in price growth and paydown |
| Any market, all cash | Same property, no loan | Equal to the cap rate | The unlevered baseline every financed return should beat |
Ranges assume a full expense load including management and reserves. Self-managing adds roughly 8% of rent back to cash flow.
Two rules follow. Compare a property against its own market, because a 5% return is weak in Cleveland and strong in Tampa. And compare the financed return against the cap rate: if the loan rate is above the cap rate, leverage is lowering your cash-on-cash, and the deal only works if you expect appreciation.
The levers that move the number
Each lever below is applied to the worked example on its own, so the effect is isolated. The ranking is the useful part: rent and self-management move the return far more than the down payment does.
| Change | Annual cash flow | Cash invested | Cash-on-cash |
|---|---|---|---|
| Baseline | $2,651 | $55,850 | 4.75% |
| Self-manage instead of paying 8% | $4,523 | $55,850 | 8.10% |
| Rent $2,050 instead of $1,950 | $3,551 | $55,850 | 6.36% |
| 20% down instead of 25% | $1,931 | $46,600 | 4.14% |
| Buy for $175,000 instead of $185,000 | $3,235 | $53,350 | 6.06% |
Each row changes one input. The 20%-down row shows the leverage effect: less cash in, but the larger loan costs more than the freed cash earned.
The purchase price row is the one you control most directly. Ten thousand dollars off the price added $584 to annual cash flow and took $2,500 out of the cash invested, and the return rose by more than a point. That is why the offer, not the rent estimate, is where most of the return is won.
Four mistakes that inflate the figure
A cash-on-cash return is only as honest as its inputs. These four errors account for most of the gap between the return an investor expected and the one the property delivered.
- Dividing by the down payment alone. Closing costs and initial repairs are cash invested. On the example above, ignoring them turns 4.75% into 5.7%.
- Skipping vacancy, maintenance and reserves. A property with zero vacancy and zero repairs does not exist. Budget 5% for vacancy and 10% to 12% for maintenance and capital items combined.
- Using the seller's tax bill. Most counties reassess after a sale. Estimate taxes on your purchase price at the local rate, not on the seller's assessed value.
- Pricing management at zero. Self-managing is a job, not a return. Run the number with management included, then decide whether you want to be paid that 8% for the work.
The result is a metric worth trusting: a first-year return on your actual cash, from the property as you would actually finance it. Pair it with cap rate for the unlevered view and with IRR for the whole holding period, and you have the three numbers a purchase decision needs.

Frequently asked questions
What is a good cash-on-cash return on a rental property?
It depends on the market you are buying in. Cash flow markets in the Midwest and South commonly produce 8% to 12% at 2026 prices and rates. Balanced metros land between 5% and 8%. Appreciation markets on the coasts and in the Sun Belt boom cities often deliver 2% to 5%, and investors there accept it because most of the return comes from price growth. Compare a deal against its own market, not against a national figure.
What counts as cash invested in the cash-on-cash formula?
Every dollar you put in before the property produces rent: the down payment, closing costs, lender fees and points, any repairs needed before the first tenant, and reserves you fund at purchase. Leaving out closing costs or the initial repair budget is the most common way the figure ends up flattered.
Is cash-on-cash return the same as ROI?
No. Cash-on-cash counts only the cash flow you receive in a year. ROI adds the other ways a rental pays you: the principal the tenant pays down and the appreciation the property gains. A property can show a 4% cash-on-cash return and a 15% total ROI in the same year.
Does cash-on-cash return include the mortgage payment?
Yes. Cash flow is what is left after every operating expense and the full mortgage payment, principal and interest. That is what separates cash-on-cash from cap rate, which stops at net operating income and ignores financing.
Why does my cash-on-cash return fall when I put less money down?
Because the loan costs more than the property earns. When the interest rate on the loan is higher than the property's cap rate, every extra dollar of debt reduces cash flow faster than it reduces the cash invested. At 2025 and 2026 rates that is the usual case, so a bigger down payment often produces a higher cash-on-cash return even though it ties up more money.
