Cash-on-Cash Return Calculator: What Your Investment Actually Earns
Calculate cash-on-cash return on rental property investments. See your actual annual return on invested cash after mortgage payments and operating expenses.
Cap rate gets a lot of attention, but cash-on-cash return is what actually matters to most investors — because most people use financing. It tells you what percentage of your out-of-pocket cash you get back each year in actual cash flow. No theoretical assumptions, just dollars in vs. dollars out.
Use the CalcHub Cash-on-Cash Calculator to see your real return after debt service.
The Formula
Cash-on-Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested × 100 Annual Pre-Tax Cash Flow = NOI − Annual Mortgage Payments (P&I) Total Cash Invested = Down Payment + Closing Costs + Initial Repairs/RehabNotice it's pre-tax cash flow — you account for taxes separately when doing full investment analysis.
What Counts as "Cash Invested"
People sometimes undercount this, which makes returns look better than they are:
| Cost Item | Include? |
|---|---|
| Down payment | Yes |
| Closing costs (loan origination, title, etc.) | Yes |
| Immediate repairs before renting | Yes |
| Reserves set aside | Debatable — conservative investors include it |
| Ongoing monthly expenses | No — those come out of NOI |
Worked Example
Purchase price: $350,000 | Down: $70,000 (20%) | Rate: 7% | 30-year fixed
- Monthly mortgage (P&I): $1,863
- Annual debt service: $22,356
- Gross rent: $2,800/mo = $33,600/year
- Vacancy (5%): −$1,680
- Property taxes: −$4,200
- Insurance: −$1,400
- Management (8%): −$2,688
- Maintenance: −$2,500
- NOI: $21,132
That's negative cash flow — the property costs you $102/month out of pocket. Your cash-on-cash return would be negative at current rent levels and financing costs.
Now if rents are $3,200/month instead:
- NOI would be approximately $26,000
- Cash flow: $26,000 − $22,356 = $3,644/year
- Cash-on-cash: $3,644 ÷ $76,000 (down + closing) = 4.8%
Benchmarks: What's Considered Good?
| CoC Return | Interpretation |
|---|---|
| Less than 0% | Negative cash flow — you're subsidizing the property |
| 1–4% | Low but might accept for appreciation potential |
| 5–8% | Solid for most markets |
| 8–12% | Strong — typically found in secondary markets |
| 12%+ | Exceptional or high risk |
Cash-on-Cash vs. Total Return
Cash-on-cash only measures income return. It doesn't include:
- Principal paydown (equity building through mortgage payments)
- Appreciation
- Tax benefits (depreciation)
The full picture is better than cash-on-cash alone, but CoC is the most honest near-term cash flow indicator. If the CoC is negative and you're banking on appreciation bailing you out, be honest about that risk.
What's the difference between CoC and ROI?
ROI includes all returns (appreciation, equity, tax benefits), while cash-on-cash only counts actual cash flowing to you each year. CoC is more conservative and tangible.
How do I account for a HELOC or cash-out refi as my down payment?
If your "down payment" came from another loan, your true cash invested includes the cost of that borrowing. The calculator lets you enter your total cash outlay — it doesn't care where the cash came from.
What cash-on-cash should I target as a beginner?
A common rule: don't accept negative cash flow unless you have strong conviction about appreciation. A 5–6% CoC is a reasonable starting target that leaves room for unexpected expenses without eating you alive.
