This calculator gives an estimate only and is not investment advice. Cash-on-cash return ignores appreciation, loan principal paydown, tax effects and vacancy you have not accounted for. Real returns depend on accurate rent, expense and financing assumptions that can change. Confirm every figure and speak to a qualified property or financial professional before you buy.
Annual cash flow: -
Cash-on-cash return (CoC) measures the annual pre-tax cash flow a rental property produces as a percentage of the actual cash you put in. It answers a simple question: for every dollar of your own money tied up in the deal, how many cents does it return each year? Enter your annual cash flow and total cash invested (or build the cash flow from income, expenses and debt service) and this calculator shows your CoC return instantly.
What is the Cash on Cash Return Calculator?
Cash-on-cash return is a cash-flow yield. The formula is cash-on-cash return = annual pre-tax cash flow / total cash invested x 100. Annual cash flow is the money left after operating expenses and any loan payments (debt service) are paid out of your rental income. Total cash invested is the real out-of-pocket money you committed to acquire and ready the property: the down payment, closing costs, and any upfront rehab or repairs. Because it divides cash returned by cash in, the result is a clean annual percentage you can compare against other investments.
What makes cash-on-cash different from simpler measures is the word cash. Unlike capitalization rate (cap rate), which uses net operating income and the full property value as if you paid all cash, CoC reflects leverage. If you finance most of the purchase with a mortgage, your cash in is small relative to the property, so a modest cash flow can translate into a high percentage return on the slice of money that is actually yours. This is why two investors buying the identical property can report very different cash-on-cash returns depending on how much they borrowed.
Cash-on-cash is a snapshot of one year and only counts cash. It deliberately ignores appreciation in the property value, the equity you build as your loan principal is paid down, and the tax benefits of depreciation. A deal can show a low CoC but still be excellent once those are added in, or show a high CoC while hiding deferred maintenance and vacancy risk. Treat it as one lens among several (alongside cap rate, total return and a full proforma), not as the single number that decides a purchase.
When to use it
- Screening rental property deals quickly to see which ones return enough cash on the money you actually invest.
- Comparing a financed purchase against an all-cash purchase to see how leverage changes your annual yield.
- Checking whether a property meets a personal target (for example a minimum 8% cash-on-cash) before you make an offer.
- Showing a partner or lender the pre-tax cash yield on the capital committed to a deal.
How to use the Cash on Cash Return Calculator
- Choose whether to enter your annual pre-tax cash flow directly or build it from income, expenses and debt service.
- If building it, enter annual rental income, annual operating expenses, and annual debt service (loan payments).
- Enter your total cash invested: down payment, closing costs, upfront rehab, and any other out-of-pocket cash.
- Read off your cash-on-cash return percentage, along with the cash flow and total cash invested used in the calculation.
Formula & method
Worked examples
You buy a rental with $50,000 down, $5,000 closing costs and $5,000 of upfront repairs, and it nets $4,800 of pre-tax cash flow in the first year.
- Total cash invested = 50,000 + 5,000 + 5,000 = 60,000
- Annual pre-tax cash flow = 4,800
- CoC = 4,800 / 60,000 = 0.08
- 0.08 x 100 = 8.00%
Result: Cash-on-cash return = 8.00%
A property earns $24,000 rent a year, with $7,200 operating expenses and $12,000 of mortgage payments, and you have $60,000 of cash in the deal.
- Annual cash flow = 24,000 − 7,200 − 12,000 = 4,800
- Total cash invested = 60,000
- CoC = 4,800 / 60,000 = 0.08
- 0.08 x 100 = 8.00%
Result: Cash-on-cash return = 8.00%
How annual cash flow changes the cash-on-cash return on $60,000 invested
| Annual cash flow | Total cash invested | Cash-on-cash return |
|---|---|---|
| $3,000 | $60,000 | 5.00% |
| $4,800 | $60,000 | 8.00% |
| $6,000 | $60,000 | 10.00% |
| $7,200 | $60,000 | 12.00% |
| $9,000 | $60,000 | 15.00% |
Rough guide to how investors read cash-on-cash returns (varies by market and risk)
| CoC range | Common interpretation |
|---|---|
| Below 4% | Often weak for a leveraged rental, may rely on appreciation |
| 4% to 7% | Modest, common in expensive low-cap-rate markets |
| 8% to 12% | Frequently cited target range for buy-and-hold rentals |
| Above 12% | Strong cash yield, check the assumptions and risk carefully |
Common mistakes to avoid
- Using net operating income instead of cash flow. Cash-on-cash uses cash flow after debt service, not net operating income (NOI). NOI excludes loan payments and belongs in the cap rate calculation. Subtract your mortgage payments before dividing, or you will overstate the return on a financed deal.
- Leaving out closing costs and rehab. Total cash invested is more than the down payment. Closing costs, loan fees and upfront repairs are real money out of your pocket and belong in the denominator. Omitting them shrinks the cash invested and flatters the return.
- Treating cash-on-cash as total return. CoC counts only cash flow. It ignores appreciation, the equity you gain as the loan is paid down, and tax benefits. A deal can have a low CoC but a healthy total return once those are included, so do not judge a purchase on this number alone.
- Forgetting vacancy and maintenance reserves. If your expense figure leaves out vacancy, repairs and capital reserves, the cash flow (and the return) is too optimistic. Build realistic allowances into operating expenses so the percentage reflects a normal year, not a perfect one.

Frequently asked questions
What is a cash-on-cash return?
Cash-on-cash return is the annual pre-tax cash flow a property produces divided by the total cash you invested, shown as a percentage. It tells you the yearly cash yield on your own money in the deal, after operating expenses and loan payments.
How do you calculate cash-on-cash return?
Divide annual pre-tax cash flow by total cash invested, then multiply by 100. Cash flow is rental income minus operating expenses minus debt service. Total cash invested is the down payment plus closing costs, rehab and any other upfront cash.
What is a good cash-on-cash return?
It depends on your market and risk tolerance, but many buy-and-hold investors target somewhere in the 8% to 12% range. In expensive, low-cap-rate areas, returns of 4% to 7% are common because investors expect more from appreciation.
What is the difference between cash-on-cash return and cap rate?
Cap rate uses net operating income and the full property value, as if you paid all cash, so it ignores financing. Cash-on-cash uses cash flow after loan payments and only the cash you actually invested, so it reflects how leverage changes your return.
Does cash-on-cash return include appreciation?
No. Cash-on-cash counts only cash flow in a single year. It deliberately leaves out property appreciation, the equity you build as the loan principal is paid down, and tax benefits like depreciation, so it understates total return.
Should I use pre-tax or post-tax cash flow?
Cash-on-cash return is conventionally calculated on pre-tax cash flow, because tax outcomes vary by investor. Use the annual cash flow before income tax, after operating expenses and debt service, to keep your figure comparable to how the metric is usually quoted.
