Cash on cash return explained
What is a cash on cash return calculator?
Cash on cash return is the first-year cash yield on the money you leave in a rental property. A cash on cash return calculator divides annual pre-tax cash flow by total cash invested and expresses the result as a percentage. Investors use a real estate cash on cash return calculator to compare properties, down payments, and upfront costs on a like-for-like basis. Unlike a cap rate, which measures the property’s unleveraged yield, CoC measures the return on your actual equity after debt service.
Cash on cash return calculator formula
The cash on cash return calculator formula has two inputs:
Cash on cash return formula
Cash-on-Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested × 100
Annual pre-tax cash flow is net operating income minus annual debt service. It is the cash the property produces before income taxes, not the property’s NOI. Total cash invested is the cash required to close and stabilize the deal: down payment, closing costs, rehab, lender fees, and other upfront cash. Multiply by 100 to express the result as a percentage. For example, $6,000 of annual pre-tax cash flow on $60,000 of total cash invested is a 10% cash on cash return.
How to calculate cash on cash return
To calculate cash on cash return, follow four steps:
- 01Calculate annual pre-tax cash flow. Start with gross scheduled rent, subtract vacancy and operating expenses to get NOI, then subtract annual debt service.
- 02Add up total cash invested. Include the down payment, closing costs, immediate rehab, lender fees, and other upfront cash.
- 03Divide annual pre-tax cash flow by total cash invested.
- 04Multiply by 100 to convert the result to a percentage.
A cash on cash return calculation is only comparable when both deals use the same convention. A down-payment-only result will look higher than an all-in result, even when the cash flow is identical.
Cash on cash return calculation example
Using the calculator’s default deal, the property produces $17,652 of NOI and $11,975 of annual debt service, leaving $5,677 of annual pre-tax cash flow. Total cash invested is $56,000: a $50,000 down payment plus $6,000 in closing costs and other upfront cash. The cash on cash return calculation is 10.14%. On the down payment alone, the same cash flow equals 11.35%, which shows why the cash invested convention matters.
Example deal
$200,000 price · $2,300 rent · 25% down · 7% for 30 years
- Net operating income
- $17,652
- Annual debt service
- −$11,975
- Annual pre-tax cash flow
- $5,677
- Down payment
- $50,000
- Closing costs and other cash
- $6,000
- Total cash invested
- $56,000
- Down-payment-only CoC
- 11.35%
- Cash-on-cash return
- 10.14%
The denominator changes the answer.
The same deal produces 11.35% on the down payment alone and 10.14% on total cash invested. Both are valid views; the important thing is to compare deals using the same convention.

What counts as total cash invested?
Total cash invested is the denominator, and it is the assumption most likely to make two CoC numbers incomparable. The headline result uses all-in cash invested; the secondary output uses the down payment only. Both are valid, but the all-in number matches the cash a buyer actually needs to close and stabilize the property. Use the table to see what each convention includes, and disclose your convention when comparing deals.
| Item | All-in CoC | Down-payment-only CoC |
|---|---|---|
| Down payment | Included | Included |
| Closing costs | Included | Excluded |
| Rehab budget | Included | Excluded |
| Lender fees | Included | Excluded |
| Other upfront cash | Included | Excluded |
| Best use | Comparing total cash required | Comparing leverage and down-payment efficiency |
How to use this rental property cash on cash return calculator
Start with the deal inputs: purchase price, rent, vacancy, taxes, insurance, management, maintenance, capex, and utilities. Advanced mode adds lender fees, PMI, other upfront cash, and a separate annual reserve. The calculator updates CoC, cash flow, cash invested, loan constant, leverage spread, payback, and break-even interest rate in real time.
Use the financing scenarios to compare all cash, 20% down, and a lower down payment. The sensitivity grid and reverse solves show the rent or purchase price needed to hit your target cash on cash return. Save deals, compare two scenarios, copy a share link, export CSV, or print the result; everything runs in your browser.
Cash on cash vs. cap rate
Cap rate divides NOI by the property’s acquisition basis, usually the purchase price. Cash on cash divides annual pre-tax cash flow by total cash invested. Cap rate is unleveraged and financing-neutral; CoC is after debt service and reflects your actual equity check. A property can have a healthy cap rate and a weak CoC when the loan constant is high, or a modest cap rate and a strong CoC when leverage is positive.
How leverage affects cash on cash return
Leverage is the reason two investors can buy the same property and report different cash on cash returns. When the property’s cap rate is higher than the loan constant (annual debt service divided by the loan amount), debt is accretive: it raises the return on the equity invested. When the loan constant is higher than the cap rate, the deal has negative leverage, and borrowing reduces the cash yield. The calculator shows the cap rate, loan constant, and leverage spread side by side. In the default deal, the cap rate is 8.83%, the loan constant is 7.98%, and the spread is +0.84 pp, a positive leverage scenario. A positive spread does not eliminate risk; it means the debt is helping the cash return under the current assumptions.
Cash on cash return after a refinance
Cash on cash return can also be measured after a refinance, especially in a BRRRR. The numerator stays annual pre-tax cash flow, but the denominator becomes the cash left in the deal after the new loan pays off the old one and returns capital. If the refinance returns all of your original cash, the denominator approaches zero, so the ratio becomes mathematically unstable and is often shown as unavailable. The BRRRR calculator models cash left in the deal, post-refinance cash flow, and post-refi DSCR so you can see whether the deal truly recycled its capital. The cash left in the deal guide covers the formula in more detail.
How to improve cash on cash return
Cash on cash return moves when any of its inputs change. The most reliable levers are:
- Negotiate a lower purchase price, which reduces the loan, down payment, closing costs, and debt service.
- Raise rent toward market, but do not assume rent the property cannot support.
- Reduce vacancy and turnover through screening, lease terms, and faster turns.
- Audit taxes, insurance, management, maintenance, capex, HOA dues, and utilities.
- Improve financing terms. A lower rate or lower lender fees can raise CoC; a smaller down payment raises CoC but also raises risk and debt service.
Use the sensitivity grid to see how rent and interest rate changes affect the result, and confirm that any improvement is realistic before you count it. An optimistic pro forma can make CoC look better without improving the deal.
Cash on cash return vs. ROI and IRR
Cash on cash return is not the same as ROI or IRR. It is a single-year, pre-tax cash measure: annual pre-tax cash flow divided by total cash invested. ROI is a broader term that can include principal paydown, appreciation, tax benefits, and sale proceeds. IRR accounts for the timing of all cash flows over a holding period. A deal with a strong first-year CoC can still produce a weak IRR if cash flow falls or exit proceeds disappoint, and a deal with a modest CoC can produce a strong total return through amortization and appreciation. Use CoC for year-one cash yield, then use a multi-year model for total return. The methodology explains which return sources are included in each calculator.
What is a good cash on cash return?
There is no universal good cash on cash return. A target depends on the market, property type, condition, risk, financing, and the return available on other investments. A higher CoC can be better, but it can also come from optimistic rent, understated expenses, or a low down payment that raises risk. Set a target before you shop, then stress-test rent, vacancy, and interest rates. Read the guide to what is a good cash on cash return for a practical framework.
Limitations and common mistakes
Cash on cash return is a first-year, pre-tax cash measure. The headline result excludes principal paydown, income taxes, depreciation, appreciation, and sale proceeds. It also assumes your rent and expense inputs are realistic. Common mistakes include omitting vacancy, using the down payment as the only cash invested, counting principal paydown as cash flow, and comparing deals that use different conventions. Use CoC as one screen, then pair it with cap rate, DSCR, cash flow, and a downside scenario.
