How to Calculate Cash on Cash Return for Rental Properties
Cash on cash return is the single best metric for comparing rental property investments. Learn the formula, see real examples, and understand what a good CoC return looks like in 2026.
Cash on cash return (CoC) is arguably the most important metric for rental property investors. Unlike cap rate, which ignores how you finance the deal, cash on cash tells you exactly what your actual invested dollars are earning.
The Cash on Cash Return Formula
Cash on Cash Return = Annual Pre-Tax Cash Flow / Total Cash Invested × 100
That's it. Two numbers:
- Annual Pre-Tax Cash Flow — the money left in your pocket after all expenses and mortgage payments
- Total Cash Invested — your down payment, closing costs, and any renovation costs
A Real-World Example
Let's say you buy a rental property for $300,000:
| Item | Amount |
|---|---|
| Purchase Price | $300,000 |
| Down Payment (25%) | $75,000 |
| Closing Costs | $6,000 |
| Repairs/Renovation | $9,000 |
| Total Cash Invested | $90,000 |
Now for the income side:
| Item | Monthly | Annual |
|---|---|---|
| Gross Rent | $2,200 | $26,400 |
| Vacancy (5%) | -$110 | -$1,320 |
| Property Management (8%) | -$176 | -$2,112 |
| Insurance | -$125 | -$1,500 |
| Property Tax | -$250 | -$3,000 |
| Maintenance Reserve | -$183 | -$2,200 |
| Net Operating Income | $16,268 | |
| Mortgage Payment | -$1,194 | -$14,328 |
| Annual Cash Flow | $1,940 |
Cash on Cash Return = $1,940 / $90,000 × 100 = 2.16%
That's not great. But let's see how small changes can dramatically improve this number.
What's a Good Cash on Cash Return?
Here are general benchmarks for 2026:
| CoC Return | Rating | Notes |
|---|---|---|
| Below 4% | Poor | Barely beating a savings account |
| 4–6% | Acceptable | Common in expensive markets |
| 6–8% | Good | Solid return for most investors |
| 8–12% | Very Good | Strong cash-flowing property |
| 12%+ | Excellent | Rare — usually requires value-add or creative financing |
Keep in mind, these benchmarks don't account for appreciation, tax benefits, or loan paydown — all of which add to your total return.
Cash on Cash vs. Cap Rate vs. Total ROI
These three metrics answer different questions:
- Cap Rate: "What's this property earning relative to its value?" (Ignores financing)
- Cash on Cash: "What's my actual cash earning on the money I invested?" (Includes financing)
- Total ROI: "What's my complete return including appreciation, tax benefits, and equity buildup?"
Cash on cash is the best metric for comparing deals because it factors in your specific financing terms. Two identical properties can have wildly different CoC returns depending on interest rate, down payment, and loan terms.
How to Improve Your Cash on Cash Return
1. Put Less Money Down
A smaller down payment means less cash invested — but higher mortgage payments. There's a sweet spot where your CoC peaks. For many markets, 20–25% down optimizes CoC.
2. Negotiate a Better Price
Every dollar you save on purchase price is a dollar less invested. A $10,000 price reduction on a $300,000 property improves your CoC by roughly 0.2–0.5%.
3. Increase Rent
Even a $50/month rent increase adds $600/year to cash flow. On a $90,000 investment, that's a 0.67% CoC improvement.
4. Reduce Expenses
Shop insurance annually, contest property tax assessments, and handle minor repairs yourself. Saving $200/month improves your CoC by 2.67%.
5. Use Creative Financing
Seller financing, assumable mortgages, or house hacking strategies can dramatically reduce your cash invested while maintaining or increasing cash flow.
The Hidden Returns Cash on Cash Doesn't Show
A 6% cash on cash return might seem modest, but rental properties generate returns in four ways:
- Cash Flow (what CoC measures)
- Appreciation — historically 3–4% per year
- Loan Paydown — your tenant is paying off your mortgage
- Tax Benefits — depreciation, expense deductions, potential REP status
When you add all four, a property with a 6% CoC return might actually deliver 15–20% total annual return on your investment.
