Cap rate gets the attention. But for any investor using financing — which is most of us — cash-on-cash return (CoC) is the metric that actually tells you what your money is earning.
How to Calculate Cash-on-Cash Return
Cash-on-Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested
Example: You put $50,000 into a rental (down payment + closing costs). The property generates $5,200/year in cash flow after all expenses including the mortgage. CoC = $5,200 ÷ $50,000 = 10.4%
What Is a Good Cash-on-Cash Return in 2025?
In 2025's interest rate environment, targets have shifted:
- Exceptional: 12%+ CoC
- Strong: 8-12% CoC
- Acceptable: 6-8% CoC (if in a strong appreciation market)
- Marginal: 4-6% CoC — only in very high-appreciation markets
- Avoid: Below 4% CoC — you can earn this in a money market with zero risk
The rate sensitivity problem: At 4% interest rates (2020-2021), CoC returns were easy to hit. At 7% rates (2024-2025), the same properties often deliver 2-4% lower CoC. Run your numbers at today's actual rate. Don't model what you hope rates will do.
Cash-on-Cash vs. Cap Rate — Which Matters More?
Cap rate is financing-agnostic — it measures the property's inherent yield. Cash-on-cash is financing-inclusive — it measures what YOU earn on YOUR money. For a leveraged investor, CoC is far more relevant because it reflects your actual investment performance after debt service.
How to Improve Cash-on-Cash Return
- Buy at a bigger discount — Lower purchase price = lower mortgage = higher CoC
- Reduce financing costs — Each 0.5% rate improvement can add 1-2% CoC
- Increase rent — Value-add renovations that justify rent increases directly improve CoC
- Reduce vacancy — Every month vacant costs 8% of annual rent
- House-hack — Living in one unit eliminates your largest expense (housing) and dramatically improves CoC
