This cash-on-cash return calculator measures the annual pre-tax cash yield on the money you commit to a rental investment. Enter cash flow after debt payments, itemize your cash investment, and compare the result with a target you choose.
Use actual cash on both sides of the fraction. Rent is not cash flow, loan proceeds are not your equity contribution, and appreciation is not money available to spend. The calculator also shows the annual cash flow needed for a target yield and the maximum invested cash that a positive cash flow can support at that target.
How to use the cash-on-cash return calculator
- Estimate annual pre-tax cash flow after operating expenses and the entire debt payment. If you plan to retain cash for future replacements, use cash flow after that allowance.
- Enter the down payment. For an all-cash purchase, enter the full purchase price instead.
- Add acquisition costs, initial repairs and reserves funded with your cash. Exclude the portion financed by the loan.
- Add any other cash committed to make the property rentable, without entering the same cost twice.
- Set your target percentage and inspect the sensitivity chart. Copy the link to save or share the assumptions.
If you only know the rent, start with the rental property cash flow calculator. Bring its annual after-reserve figure here. A month of unusually high collections is not automatically a representative year; use a budget that includes vacancy, repairs and irregular expenses.
Cash-on-cash return formula
cash-on-cash (%) = annual pre-tax cash flow ÷ invested cash × 100annual cash flow needed = invested cash × target rate ÷ 100maximum invested cash = annual cash flow ÷ (target rate ÷ 100)
The reverse investment calculation requires positive cash flow and a positive target. A zero target does not set a useful maximum investment. The main ratio requires invested cash greater than zero and accepts negative annual flow so a loss remains visible.
JPMorgan Chase describes cash-on-cash as a cash-flow measure that excludes appreciation and equity growth from amortization. This tool uses that annual before-tax approach and makes reserve treatment explicit. It does not forecast distributions, growth or a future sale.
Worked example: $70,000 invested
Suppose the property needs a $50,000.00 down payment, $6,000.00 of cash-paid closing and loan costs, $10,000.00 of initial repairs and a $4,000.00 funded reserve. Together these commit $70,000.00.
| Calculation | Result |
|---|---|
| Annual cash flow after expenses, debt and planned reserves | $6,000.00 |
| Monthly equivalent | $500.00 |
| Annual flow ÷ invested cash | 8.57% |
| Annual cash flow needed for an 8% target | $5,600.00 |
| Annual flow above that target | $400.00 |
| Maximum invested cash at $6,000 flow and 8% | $75,000.00 |
These are invented inputs, not a typical property or expected yield. The target comparison says how this scenario relates to the rate you entered; it does not establish whether the property is a good purchase.
How cash flow and upfront costs change the return
Reducing the denominator improves the displayed ratio only if the numerator and risk remain comparable. Skipping a real repair or needed reserve can make the percentage look attractive while leaving the investment underfunded.
| Annual cash flow | $60,000 invested | $70,000 invested | $80,000 invested |
|---|---|---|---|
| -$2,400.00 | -4.00% | -3.43% | -3.00% |
| $3,000.00 | 5.00% | 4.29% | 3.75% |
| $6,000.00 | 10.00% | 8.57% | 7.50% |
| $9,000.00 | 15.00% | 12.86% | 11.25% |
At $70,000.00 invested, a recurring $100 monthly expense reduces annual flow by $1,200 and the annual cash yield by 1.71% percentage points. A $3,000 replacement funded from current-year cash has a different timing effect from a recurring $250 monthly expense, even though both total $3,000 for that year.
Debt service, principal paydown and cash reserves
Subtract the full debt payment when measuring the cash available to the owner. Interest is a borrowing cost; principal reduces debt. Both leave the bank account. A taxable-income worksheet may treat them differently, which is why taxable rental profit should not be pasted into this tool without adjustment.
A funded opening reserve increases the cash committed to the investment. An annual replacement allowance reduces the cash you can distribute that year. Those are different cash movements. If you later spend an amount already covered by a reserve account, reconcile the transfer and the expenditure rather than counting both against the same cash-flow period.
For a property acquired halfway through the year, distinguish actual partial-year cash flow from an annual operating forecast. Multiplying a short stable period by twelve can help make a scenario, but it does not include a lease-up delay or a seasonal repair bill unless you add those assumptions.
Cash-on-cash vs cap rate, ROI and IRR
| Measure | Question it answers |
|---|---|
| Cap rate | How much annual property NOI is generated relative to property value, before financing? |
| Cash-on-cash return | How much annual pre-tax cash flow does the committed cash produce? |
| Total ROI | What profit results when the stated income, costs and exit are included? |
| IRR / NPV | How do the amounts and dates of cash contributions, distributions and sale proceeds affect value? |
Use the cap rate calculator for the property's operating yield and the house flipping calculator for a purchase-rehab-resale budget. The latter's project ROI covers the whole modeled flip, so it should not be read as this tool's annual rental yield.
Common mistakes and when to use a fuller analysis
- Using gross rent as the numerator. First account for vacancy, operating costs, borrowing and the cash you retain.
- Entering property price as financed equity. For a leveraged purchase, include your cash contribution and related cash costs, not the lender's principal.
- Ignoring acquisition costs. They commit cash even if they do not produce additional rent.
- Adding principal paydown back into cash flow. Equity growth is valuable, but it is not a cash distribution.
- Calling the ratio a payback guarantee. Future operating cash, contributions and sale value can change.
Refinancing can return equity and change the cash still tied up in a property. State which investment basis you use; dividing a later year's cash flow by near-zero remaining cash can produce an enormous ratio that conceals the original contributions. Uneven distributions, repeated capital calls, ownership splits, taxes and sale proceeds require a dated cash-flow model. This tool is a single annual comparison for general information.
Frequently asked questions
How do you calculate cash-on-cash return?
Divide annual pre-tax cash flow by total cash invested and multiply by 100. In the example, $6,000.00 ÷ $70,000.00 × 100 = 8.57%.
What is included in total cash invested?
Include the down payment or cash purchase amount, acquisition and financing costs paid in cash, initial cash-funded repairs, the funded opening reserve and other cash contributions. Exclude loan proceeds and costs paid entirely from those proceeds.
Does cash-on-cash return include principal payments?
The full principal-and-interest debt payment reduces available cash flow. Principal reduction can build equity, but it is not cash distributed to you and is not added back to the numerator here.
Can cash-on-cash return be negative?
Yes. A $2,400 annual cash deficit on $70,000.00 invested cash gives −$2,400 ÷ $70,000.00 × 100 = -3.43%.
What is a good cash-on-cash return?
There is no universal rate that makes a property suitable. Compare risk, financing, condition, cash needs and alternative uses of the money. The target input is your assumption, not an investment recommendation.
Does this include appreciation or sale profit?
No. This annual cash yield excludes unrealized appreciation, sale proceeds and principal-paydown equity. Evaluate the complete holding period separately when those amounts matter.
What if total cash invested is zero?
The ratio is undefined. A no-cash-down structure can still have fees, reserves, guarantees or future cash requirements. Enter the cash actually committed; the tool does not display an infinite return.
Are reserves counted twice?
An opening funded reserve belongs in invested cash. New annual cash set aside for replacements reduces distributable annual cash flow. Do not subtract an opening transfer again as a recurring annual expense or subtract the same repair from both a reserve withdrawal and a second spending line.
