Cap Rate Guide (2026)
Cap Rate Calculator: How to Evaluate Rental Properties in 2026
Cap rate is the fastest way to compare rental properties before you know the financing terms.
It strips out the mortgage and shows you what a property earns relative to its price, so you
can stack deals side by side on a level playing field.
Once you find a deal with a compelling cap rate, use the rental property cash flow calculator
to layer in your financing and see whether monthly cash flow still holds up after debt
service.
The cap rate formula
Cap Rate = Net Operating Income ÷ Purchase Price × 100
Net Operating Income (NOI) is gross scheduled rent, minus vacancy loss, minus all operating
expenses — property taxes, insurance, maintenance, property management, and capital
expenditure reserves. It does not include mortgage payments.
| Line item | Example (annual) | Notes |
| Gross scheduled rent | $30,000 | 12 × market rent |
| Vacancy loss | −$1,500 | 5% assumption |
| Operating expenses | −$10,800 | Taxes, insurance, mgmt, maintenance, capex |
| NOI | $17,700 | Before mortgage |
| Purchase price | $295,000 | Acquisition cost |
| Cap rate | 6.0% | $17,700 ÷ $295,000 |
Cap rate benchmarks by market type (2026)
There is no universal cap rate threshold that defines a "good deal." The right benchmark
depends on local supply, demand, and the liquidity of the market. Use these ranges as a
starting point, then verify against recent comparable sales in your target area.
| Market type | Typical range | Interpretation |
| Gateway metros (NYC, LA, SF) | 3–5% | Appreciation-driven; cash flow often thin |
| Secondary Sun Belt (Phoenix, Tampa) | 5–7% | Balance of growth and income |
| Midwest cash flow markets | 7–10% | Higher income; lower appreciation expectations |
| Value-add or distressed | 10%+ | Higher risk and execution requirements |
A cap rate well below local averages may signal an overpriced asset or above-market rent
that will not hold. A cap rate well above local averages often signals deferred maintenance,
management problems, or a declining neighborhood — not free money.
Cap rate vs. cash-on-cash return: when to use each
Both metrics measure return, but they answer different questions. Using the wrong metric at
the wrong stage of analysis leads to bad decisions.
- Use cap rate to screen and compare properties before you have financing
terms. It normalizes the return so leveraged and unleveraged deals sit on the same scale.
- Use cash-on-cash return once you have a specific loan offer. It reflects
your actual out-of-pocket return on the capital you invest.
-
A high cap rate deal with expensive or short-term financing can produce a worse
cash-on-cash return than a lower cap rate deal with a long-term fixed loan.
-
Cap rate is also used to estimate property value in commercial underwriting: Value = NOI
÷ Cap Rate.
Run both metrics together on every deal using the cash flow calculator before signing a purchase
agreement.
Cap rate calculator FAQ
What is a cap rate and how do I calculate it?
Cap rate (capitalization rate) = Net Operating Income divided by Property Purchase Price, expressed as a percentage. NOI is gross rent minus vacancy minus all operating expenses, but before mortgage payments. A $200,000 NOI on a $2,500,000 property equals an 8% cap rate.
What is a good cap rate for a rental property in 2026?
It depends on the market. In high-cost coastal metros, 4–5% is common. In secondary Midwest or Sun Belt markets, 6–9% is more typical. A "good" cap rate is one that compensates you for local risk, vacancy volatility, and property age relative to alternatives in the same market.
Is cap rate or cash-on-cash return more important?
Cap rate compares properties independent of financing. Cash-on-cash return measures your actual return on invested capital after debt service. Use cap rate to screen and compare deals quickly, then switch to cash-on-cash return once you know the financing terms.
Does cap rate include the mortgage payment?
No. Cap rate uses NOI before debt service. This is intentional — it lets you compare properties as if they were bought with cash, so financing does not distort the comparison. Cash-on-cash return and monthly cash flow are the right metrics when financing terms are locked in.
Can I use cap rate for short-term rentals?
You can, but it is less reliable. STR income is volatile and seasonal, and STR operating costs are higher. Build a full 12-month projection, then annualize it to get a realistic NOI before computing the cap rate.
