Cap Rate vs Cash-on-Cash: Two Lenses for Judging a Rental
Cap rate and cash-on-cash return measure the same rental from two angles. Cap rate is the property's return before any loan: NOI divided by price. Cash-on-cash is the return on the cash you actually put down, after the mortgage. One deal produces both numbers, and they usually don't match. The gap between them is your leverage.
What is the difference between cap rate and cash-on-cash return?
Cap rate is NOI divided by property value, and it ignores financing entirely. Cash-on-cash return is annual pre-tax cash flow divided by the cash you invested, so it counts the mortgage. Cap rate measures the property; cash-on-cash measures your position in it. A cash purchase makes them identical, but a loan pulls them apart.
| Metric | Formula | Includes the loan? | What it tells you |
|---|---|---|---|
| Cap rate | NOI ÷ property value | No (unlevered) | How the property performs, financing aside |
| Cash-on-cash | Annual cash flow ÷ cash invested | Yes (levered) | The return on the money you put in |
Why do cap rate and cash-on-cash give different numbers on the same deal?
The mortgage is the whole reason. Cap rate stops at NOI, before debt service. Cash-on-cash keeps going: it subtracts the loan payment from NOI to get cash flow, then divides by your down payment instead of the full price. Because you control a $250,000 asset with maybe $70,000 down, the return on that smaller stake behaves very differently from the property's own yield.
How does leverage split the two numbers?
Leverage is the lever between them. When the cap rate is higher than your borrowing cost, financing lifts cash-on-cash above the cap rate. When your mortgage rate is higher than the cap rate, it drags cash-on-cash below it. So the same 7% cap rate can pair with a 20% cash-on-cash or a 2% one, depending on the loan and the down payment.
Stessa's numbers show the upside clearly. Take a $150,000 property with a fixed 7% cap rate. Buy it with 25% down and the cash-on-cash return is 19.3%. Drop to 10% down on the same building and it jumps to 24.6%. The cap rate never moved. Less of your own cash chasing the same net income means a higher return per dollar invested, as long as the property still cash-flows.
Cap rate vs cash-on-cash on one deal: a side-by-side
Here is a single rental run through both metrics at two down payments. Purchase price is $250,000, net operating income is $17,500, and the loan is a 30-year fixed at 6.5%. The cap rate is 7.0% in every column because the property doesn't change. Only the cash-on-cash shifts as the financing does.
| Line item | All cash | 25% down | 10% down |
|---|---|---|---|
| Purchase price | $250,000 | $250,000 | $250,000 |
| Net operating income | $17,500 | $17,500 | $17,500 |
| Annual mortgage (P&I) | $0 | $14,220 | $17,064 |
| Annual cash flow | $17,500 | $3,280 | $436 |
| Cash invested | $250,000 | $70,000 | $32,500 |
| Cap rate | 7.0% | 7.0% | 7.0% |
| Cash-on-cash | 7.0% | 4.7% | 1.3% |
Two things stand out. In the all-cash column the numbers are identical, because with no loan the cash flow equals NOI and the cash invested equals the price. And in this case leverage hurts rather than helps: a 6.5% loan costs more than the 7% cap rate leaves much room for, so each step of extra borrowing thins the cash flow. That is negative leverage, and it is common right now with mortgage rates near or above many market cap rates.
How do you calculate each one, step by step?
Both start from net operating income: gross rent minus operating expenses like taxes, insurance, management, maintenance, and a vacancy allowance. NOI never subtracts the mortgage. From there the two paths diverge, one dividing by price and the other by your cash.
- Build NOI — annual rent minus operating expenses. Say $30,000 rent minus $12,500 in expenses gives $17,500.
- Cap rate — divide NOI by price: $17,500 ÷ $250,000 = 7.0%.
- Find annual cash flow — subtract the yearly mortgage payment from NOI: $17,500 − $14,220 = $3,280.
- Total the cash in — down payment plus closing costs plus upfront repairs: $62,500 + $5,000 + $2,500 = $70,000.
- Cash-on-cash — divide cash flow by cash invested: $3,280 ÷ $70,000 = 4.7%.
When should you use each metric?
Use cap rate to shop and compare. Because it strips out financing, it lets you line up three properties in a market and judge them on equal footing, whatever loan each buyer might use. Use cash-on-cash to judge your specific deal: it tells you what your actual dollars will return once the mortgage is in place. Screen with one, decide with the other.
What are typical ranges for each?
As of 2026, cap rates for rentals generally land between 5% and 10%. Primary urban markets run 4–6%, mid-tier cities and suburbs 6–8%, and higher-risk or up-and-coming areas 8–10% or more. Multifamily deals averaged about 5.7% in 2025. For cash-on-cash, most investors target 8–12%, treating roughly 8% as a floor and 10%-plus as strong.
| Market type | Typical cap rate |
|---|---|
| Primary / coastal urban | 4–6% |
| Secondary cities & suburbs | 6–8% |
| Tertiary / higher-risk | 8–10%+ |
| Multifamily average (2025) | ~5.7% |
Context decides everything. A 5% cap rate is excellent in downtown Miami and a warning sign in a shrinking rural town. And a 6% cash-on-cash can beat an 8% one if it comes with far lower risk. Read both numbers against your own market and your own risk tolerance, not against a national headline figure.
Frequently asked questions
Can cap rate and cash-on-cash return ever be equal?
Yes, when you pay all cash. With no mortgage, your cash flow equals the NOI and your cash invested equals the purchase price, so both formulas produce the same number. The moment you add a loan, they separate.
Why is my cash-on-cash lower than my cap rate?
Your borrowing cost is higher than the cap rate, so financing works against you. When the mortgage rate tops the property's yield, every dollar of debt thins your cash flow. That is negative leverage, and it is common when rates sit near or above market cap rates.
Does the cap rate include the mortgage payment?
No. Cap rate is built from net operating income, which stops before debt service. That is exactly why it stays constant no matter how you finance the property, and why it works for comparing deals across different buyers.
Does a smaller down payment always raise cash-on-cash?
Only under positive leverage, when the cap rate beats your loan cost. Then less cash in raises the return per dollar. If your mortgage rate is higher than the cap rate, a smaller down payment can shrink cash flow and lower the return instead.
Which number do lenders and appraisers use?
Cap rate. It values the income the property itself produces, independent of any single buyer's financing. Cash-on-cash is more of an investor's personal yardstick, since it depends on your down payment, loan terms, and closing costs.
Do either of these include appreciation or tax benefits?
No. Both are pre-tax and ignore price appreciation, the equity you build as the loan amortizes, and depreciation deductions. A property can show a modest cash-on-cash return and still be a strong long-term hold once those factors are counted.
What counts as a good cash-on-cash return?
Most investors aim for 8–12%, with about 8% seen as a floor and 10% or more as strong. The right target depends on your market and how much risk you accept. A lower return backed by a stable property can beat a higher one carrying real risk.
Once you see them as two lenses on one deal, the workflow gets simple: compare properties on cap rate, then pressure-test your favorite on cash-on-cash before you commit. Drop in a purchase price and NOI on the cap rate calculator to get the unlevered number in seconds, then model your down payment and loan to see what your own cash actually earns.
