Overview
What is a cash-on-cash calculator?
A cash-on-cash return calculator divides a rental property's annual pre-tax cash flow by the total cash invested: down payment, closing costs, and upfront repairs, to show the yearly yield on the actual money you put into the deal. Unlike cap rate, it accounts for your financing, which makes it the standard metric for comparing leveraged rental deals.
How investors usually read these numbers
| Metric | Often strong | Watch out | Why it matters |
|---|---|---|---|
| Cash-on-cash return | 8% to 12%+ | Below 5% | The core yield on the money you actually invested, after financing. |
| Monthly cash flow | $200+ per unit | Negative | Dollar cushion available to absorb vacancies and repairs before the deal costs you money. |
| Cash invested vs purchase price | 25% to 30% (with closing and rehab) | Under 20% with tight cash flow | Thin cash positions boost the ratio but leave no margin when expenses surprise. |
| Vacancy assumption | 8% to 10% | 0% to 3% | Underwriting at near-full occupancy is the easiest way to inflate cash-on-cash on paper. |
How to run a cash-on-cash analysis
- 1
Total the cash you are putting in
Add your down payment, closing costs, and any upfront repairs or make-ready costs. This is the denominator of the return.
- 2
Enter monthly rent and other income
Use signed leases or local comps, plus any parking, laundry, or pet fee income.
- 3
Set vacancy and operating expenses
Apply a realistic vacancy rate (8% to 10% is standard) and include taxes, insurance, repairs, reserves, management, and HOA dues.
- 4
Enter your mortgage payment
Use the actual principal-and-interest payment from your loan quote. If you have no loan, enter $0, the result then approximates an unleveraged yield on cash.
- 5
Read cash-on-cash, annual, and monthly cash flow
Compare the return against the 8% to 12% bar many investors target, and stress-test with higher vacancy or expenses.
The math behind the result
Core formulas
- Total cash invested = down payment + closing costs + initial repairs.
- Effective monthly income = rent x (1 - vacancy rate) + other income.
- Monthly cash flow = effective income - operating expenses - mortgage payment.
- Annual pre-tax cash flow = monthly cash flow x 12.
- Cash-on-cash return = annual pre-tax cash flow / total cash invested.
Expert takeaways
- Cash-on-cash is the honest yield on your money. Cap rate rates the property; cash-on-cash rates your deal, with your loan, your closing costs, and your rehab budget in the denominator.
- Count every dollar of cash in. Skipping closing costs and initial repairs is the most common way investors flatter this number, they routinely add 4% to 8% of purchase price to the denominator.
- In a 6.5% to 7% mortgage world, many honest deals pencil at 3% to 6% cash-on-cash. The 8% to 12% deals still exist, but usually in lower-priced markets or with rents pushed by renovation.
- Leverage cuts both ways. More debt shrinks your cash invested, which can amplify cash-on-cash when the spread is positive, and turn it sharply negative when rents dip or rates rise.
- Cash-on-cash ignores appreciation, loan paydown, and taxes. A deal with modest cash-on-cash can still build serious wealth through amortization and growth; use it alongside total-return metrics, not instead of them.
Key terms in plain English
- Cash-on-cash return
- Annual pre-tax cash flow / cash invested.
- Cash-on-cash return measures the yearly cash yield on the money you personally put into a deal: down payment, closing costs, and upfront repairs. Because it uses cash flow after the mortgage, it reflects your actual financing, which cap rate deliberately ignores.
- Total cash invested
- Down payment + closing costs + initial repairs.
- Total cash invested is every out-of-pocket dollar required to acquire and stabilize the property. Leaving out closing costs or make-ready repairs shrinks the denominator and overstates the return, which is the most common error in advertised deal numbers.
- Pre-tax cash flow
- Income minus all expenses and debt service.
- Pre-tax cash flow is what lands in your account each period after vacancy, operating expenses, and the mortgage payment, before income taxes and depreciation. Annualized, it is the numerator of the cash-on-cash return.
- Cap rate
- NOI / property value, before financing.
- Capitalization rate divides net operating income by property value, ignoring the mortgage entirely. It is the right tool for comparing properties; cash-on-cash is the right tool for evaluating what your specific deal, with your specific loan, earns on your money.
- IRR
- Time-weighted total return across the hold.
- Internal rate of return accounts for all cash flows and their timing: purchase, yearly cash flow, refinances, and sale proceeds. Cash-on-cash is a single-year snapshot; IRR is the multi-year, institutional-grade measure that also captures appreciation and loan paydown.
People also ask
- What is a cash-on-cash return calculator?
- A cash-on-cash return calculator divides a rental property's annual pre-tax cash flow by the total cash invested in the deal: down payment, closing costs, and initial repairs. The result is the yearly percentage yield on the actual money you put in, after the mortgage is paid, which makes it the standard way to compare leveraged rental deals against each other and against other income investments.
- How do you calculate cash-on-cash return?
- First total your cash invested: down payment plus closing costs plus upfront repairs. Then compute annual pre-tax cash flow: effective rent (after vacancy) plus other income, minus operating expenses and twelve months of mortgage payments. Divide cash flow by cash invested. For example, $4,300 of annual cash flow on $65,000 invested is a 6.6% cash-on-cash return.
- What is a good cash-on-cash return?
- Many investors target 8% to 12% on leveraged long-term rentals, and consider anything under 5% weak unless the market has strong appreciation. In the 2026 rate environment, honest underwriting on typical properties often lands at 3% to 6%, which is why investors increasingly hunt in lower-priced, higher-yield markets. Context matters: a 6% cash-on-cash with fast rent growth can beat a static 9%.
- What is the difference between cash-on-cash return and cap rate?
- Cap rate is property-level: NOI divided by price, with no mortgage, so any buyer computes the same number. Cash-on-cash is deal-level: cash flow after your specific mortgage, divided by your specific cash outlay. Use cap rate to compare properties and markets; use cash-on-cash to decide whether your financed deal actually pays you enough for the money you are locking up.
- What is the difference between cash-on-cash return and ROI?
- Cash-on-cash measures one year's cash flow against cash invested and ignores everything else. Total ROI counts all sources of profit over the full hold: cumulative cash flow, loan paydown, appreciation, and net sale proceeds. A property can show a modest 4% cash-on-cash yet deliver a strong total ROI once equity growth is counted, which is why the two metrics answer different questions.
- How is cash-on-cash different from IRR?
- IRR is time-weighted: it accounts for when every dollar goes out and comes in across the entire hold, including the sale. Cash-on-cash is a simple one-year snapshot with no time dimension. IRR is the institutional standard for comparing multi-year investments, but it requires projecting an exit; cash-on-cash needs only this year's numbers, which makes it the workhorse screening metric.
- Does cash-on-cash return include mortgage principal paydown?
- No. The mortgage payment subtracted from cash flow includes principal, but the equity that principal builds is not credited back. That is deliberate, cash-on-cash measures spendable cash yield only. On a typical 30-year loan, paydown adds roughly 1% to 3% of additional annual return in early years, which shows up in total ROI and IRR rather than cash-on-cash.
- Why does the calculator ask for my mortgage payment directly?
- Because most buyers already have a real payment from a lender quote or an existing loan, entering it directly is more accurate than re-deriving it from rate and term assumptions. It also handles unusual financing: seller carry, adjustable rates, interest-only periods, that a standard amortization formula would miss. If you want the calculator to build the payment for you, use the rental property calculator instead.
- Can cash-on-cash return be negative?
- Yes. If vacancy, operating expenses, and the mortgage exceed rental income, annual cash flow is negative, and so is the return, you are feeding the property monthly. Some investors accept mildly negative cash-on-cash in high-appreciation markets, but it is a speculation on growth, not income investing, and it deserves a clear-eyed decision rather than an optimistic vacancy assumption.
- What cash-on-cash return do all-cash buyers get?
- With no mortgage payment, cash flow is much higher, but the cash invested is the entire purchase price plus costs, so the percentage usually lands near the property's cap rate, typically 4% to 8%. Leverage is what pushes cash-on-cash above cap rate when the spread between cap rate and borrowing cost is positive; without debt, the two metrics converge.
