How to Calculate Cash-on-Cash Return for Rental Properties

Learn how to calculate cash-on-cash return step by step with real examples. Understand what makes a good CoC return and how leverage affects your numbers.

What Is Cash-on-Cash Return?

Cash-on-cash return (CoC) is the single most important metric for rental property investors. It measures the annual pre-tax cash flow you receive relative to the actual cash you invested.

Unlike cap rate (which ignores financing) or ROI (which includes appreciation), cash-on-cash return tells you exactly what your cash investment is earning right now .

The Formula

Cash-on-Cash Return = (Annual Pre-Tax Cash Flow / Total Cash Invested) × 100

Annual Pre-Tax Cash Flow

This is your net operating income (NOI) minus your annual debt service (mortgage payments).

Annual Cash Flow = Gross Rent − Vacancy − Operating Expenses − Annual Mortgage Payments

Total Cash Invested

This includes everything you paid out of pocket:

- Down payment

- Closing costs (typically 2-5% of purchase price)

- Renovation costs (if any)

- Any reserves required by your lender

Step-by-Step Example

Let's walk through a real example:

Property Details:

- Purchase price: $250,000

- Down payment: 25% = $62,500

- Closing costs: 3% = $7,500

- Monthly rent: $2,200

- Monthly mortgage (P&I): $1,195 (at 7% on $187,500)

Monthly Expenses:

- Property tax: $250/mo

- Insurance: $125/mo

- Maintenance reserve (1%): $208/mo

- Vacancy reserve (8%): $176/mo

- Property management (10%): $220/mo

Calculation:

- Monthly cash flow: $2,200 − $1,195 − $250 − $125 − $208 − $176 − $220 = $26/mo

- Annual cash flow: $26 × 12 = $312

- Total cash invested: $62,500 + $7,500 = $70,000

- Cash-on-cash return: $312 / $70,000 = 0.45%

This deal barely breaks even. Most investors target at minimum 8-12% CoC return.

What's a Good Cash-on-Cash Return?

CoC Return Rating Interpretation

----------- -------- ---------------

12%+ Excellent Strong cash flow, likely underpriced or value-add

8-12% Good Solid rental, meets most investor thresholds

5-8% Fair Acceptable if appreciation potential exists

2-5% Poor Barely outperforms a savings account

< 2% Bad Cash drag — reconsider the deal

CoC vs. Cap Rate: What's the Difference?

Cap rate measures the property's return without financing :

Cap Rate = NOI / Purchase Price

Cash-on-cash measures your personal return including leverage:

CoC = Cash Flow After Debt / Cash Invested

Cap rate is useful for comparing properties. CoC is useful for comparing investment opportunities (stocks, bonds, real estate, etc.).

How Leverage Affects CoC Return

Leverage is a double-edged sword:

- More leverage (lower down payment) = Higher CoC if the property cash flows, because you invested less cash

- Less leverage (higher down payment) = Lower CoC but more monthly cash flow and lower risk

Example with same property:

- 25% down: CoC = 8.2%

- 20% down: CoC = 10.1% (higher return, lower cash flow)

- 30% down: CoC = 6.8% (lower return, higher cash flow)

Common Mistakes

1. Forgetting closing costs — They're part of your cash invested

2. Ignoring vacancy — Even great markets have turnover (budget 5-8%)

3. Using listed rent, not market rent — Verify with comparable leases

4. Excluding management fees — Even if self-managing, account for your time

5. Not stress-testing interest rates — A 1% rate increase can flip a deal from positive to negative
