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 cash on cash return calculator shows your CoC return instantly.
What is the Cash on Cash Return Calculator?
Cash-on-cash return is a cash-flow yield. The cash on cash return formula is cash-on-cash return = annual pre-tax cash flow / total cash invested x 100. Annual pre-tax 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, lender points, 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, which is exactly why a cash on cash return calculator is the first screen most rental investors run on a deal.
What makes cash-on-cash return 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 the cap rate vs cash on cash distinction in one line: cap rate measures the asset, cash-on-cash measures your position in it. Two investors buying the identical property can report very different cash on cash returns depending on how much they borrowed, which is why this is the headline leveraged return real estate buyers track.
Using the calculator is fast. You can enter annual pre-tax cash flow directly if you already have it, or let the tool build it from annual rental income minus annual operating expenses minus annual debt service. Then enter your total cash invested. The cash on cash return calculator divides the two, multiplies by 100, and shows the CoC percentage alongside the cash flow and cash invested it used, so you can sanity-check the inputs. Because the math is transparent, you can run several versions of a deal in seconds: change the down payment to see how leverage moves the number, raise the rehab budget, or add a vacancy allowance and watch the cash flow return on investment respond.
Cash-on-cash return 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. That makes it a conservative, honest measure of near-term liquidity, but also an incomplete one. A deal can show a low CoC but still be excellent once appreciation and amortization are added in, or show a high CoC while hiding deferred maintenance and vacancy risk. Treat the cash-on-cash return as one lens among several (alongside cap rate, total real estate return on investment and a full proforma), not the single number that decides a purchase.
Most investors run two versions of the figure. A year-one cash on cash return uses the first twelve months, which often includes lease-up, repairs and partial occupancy and therefore looks weaker. A stabilized cash-on-cash return uses a normal year once the property is fully rented and expenses have settled, and is the number you compare against a target. In a BRRRR or refinance strategy, where you pull most of your cash back out after a cash-out refinance, the total cash invested in the denominator can shrink toward zero, sending the cash on cash return very high or even to infinity. That is mathematically real but signals you should switch to total-return or equity-multiple thinking rather than leaning on CoC alone.
To make the cash on cash return trustworthy, the inputs have to be honest. Operating expenses should include property taxes, insurance, management, maintenance, capital expenditure reserves and a realistic vacancy allowance, not just the bills you see in month one. Annual debt service must reflect your actual loan terms, including any interest-only period that will later step up to fully amortizing payments. And total cash invested should capture every dollar that left your bank account, including closing costs and points, not just the down payment. Feed the calculator clean numbers and the cash flow return on investment it returns will hold up when you own the property.
When to use it
- Screening rental property deals quickly to see which ones return enough cash on the money you actually invest before you spend time on a full underwriting.
- Comparing a financed purchase against an all-cash purchase to see how leverage changes your annual yield and your cash flow return on investment.
- Checking whether a property meets a personal target (for example a minimum 8% cash-on-cash) before you make an offer or submit it to a lender.
- Showing a partner or private lender the pre-tax cash yield on the capital committed to a deal, separate from any appreciation upside.
- Modeling a BRRRR or cash-out refinance by recalculating the cash on cash return after you pull part of your invested cash back out.
- Comparing several markets side by side, where a low-cap-rate appreciation market and a high-cash-flow market produce very different CoC numbers.
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 (taxes, insurance, management, maintenance, reserves and vacancy), and annual debt service (loan payments).
- Enter your total cash invested: down payment, closing costs, lender points, 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.
- Adjust the down payment, rehab budget or expense assumptions and recalculate to compare scenarios and stress-test the deal.
Formula & method
Worked examples
You buy a single-family 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%
A small commercial property grosses $80,000 a year, with a $4,000 vacancy allowance, $26,000 of operating expenses and $36,000 of annual debt service. You invested $90,000 of cash to acquire it.
- Effective income = 80,000 - 4,000 = 76,000
- Annual cash flow = 76,000 - 26,000 - 36,000 = 14,000
- Total cash invested = 90,000
- CoC = 14,000 / 90,000 = 0.1556
- 0.1556 x 100 = 15.56%
Result: Cash-on-cash return = 15.56%
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 |
Cash-on-cash return versus related real estate return metrics
| Metric | Numerator | Denominator | Reflects financing? |
|---|---|---|---|
| Cash-on-cash return | Annual pre-tax cash flow | Total cash invested | Yes |
| Cap rate | Net operating income | Property value or price | No |
| ROI (total return) | Cash flow + appreciation + paydown | Total cash invested | Yes |
| Gross yield | Annual gross rent | Property value or price | No |
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, points and rehab. Total cash invested is more than the down payment. Closing costs, lender points 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 real estate return on investment 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.
- Comparing a year-one figure to a stabilized target. The first year often includes lease-up, partial occupancy and one-off repairs, so its cash on cash return looks weak. Compare your 8% to 12% target against a stabilized year, and label which version of the number you are quoting.
- Reading a post-refinance CoC at face value. After a cash-out refinance or in a BRRRR, you may have little cash left in the deal, which can send the cash on cash return very high or to infinity. That is real but misleading, so switch to total return or equity multiple once your invested cash is near zero.

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, points, rehab and any other upfront cash. The cash on cash return formula is CoC = cash flow / cash invested x 100.
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, a good cash on cash return of 4% to 7% is common because investors expect more from appreciation. Above 12% is strong but warrants a careful look at the assumptions.
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. That cap rate vs cash on cash gap is driven entirely by your mortgage.
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 real estate return on investment.
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 pre-tax cash flow before income tax, after operating expenses and debt service, to keep your figure comparable to how the metric is usually quoted.
What is the difference between cash-on-cash return and ROI?
Cash on cash return measures only the cash flow yield in one year. Total ROI also counts appreciation, loan principal paydown and tax effects, so it is usually higher than CoC for a property held several years. Use CoC for near-term liquidity and ROI for the full picture.
How does leverage affect cash-on-cash return?
Financing reduces your total cash invested, the denominator, while the property still produces cash flow on the full asset. A larger mortgage usually raises the leveraged return real estate produces on your slice of cash, but it also raises risk because debt service must be paid even when rent dips.
What counts as total cash invested?
Total cash invested is every dollar that left your bank account to acquire and ready the property: down payment, closing costs, lender points and loan fees, upfront rehab and repairs, and any reserves you funded at purchase. Leaving items out shrinks the denominator and overstates the return.
Can cash-on-cash return be negative or infinite?
Yes. If debt service and expenses exceed income, annual cash flow is negative and so is the cash on cash return. If a cash-out refinance returns all of your invested cash, the denominator approaches zero and the calculated return can spike toward infinity, at which point total return is the more useful measure.
