Cap Rate Explained: How to Calculate Capitalization Rate for Real Estate (2026)

What Is Cap Rate?

Capitalization rate — universally called “cap rate” in real estate — is the ratio of a property’s net operating income to its market value. It answers a simple question: if you paid all cash, what percentage of the purchase price would you earn back each year from rents?

The concept was formalized in commercial real estate finance in the post-WWII era and is now a universal standard. Every commercial real estate transaction involves cap rate analysis. It’s the primary lens investors use to compare properties, underwrite deals, and benchmark returns against other asset classes.

Unlike cash-on-cash return or ROI, cap rate ignores how you financed the property. That makes it a clean, apples-to-apples measure of a property’s intrinsic income yield.

The Cap Rate Formula

Cap Rate = NOI ÷ Property Value

Where NOI (Net Operating Income) is:

NOI = Gross Rental Income − Operating Expenses

Operating expenses include property taxes, insurance, maintenance and repairs, property management fees, and a vacancy allowance. They do notinclude mortgage payments, depreciation, or income taxes — those are financing and tax items, not operating costs.

Worked Example

This property earns 4.8 cents per dollar of value each year, before debt service. You can also flip the formula to find implied value: Property Value = NOI ÷ Cap Rate. At a 5% cap rate, that same $24,000 NOI implies a value of $480,000.

How to Calculate NOI

Getting NOI right is the most important — and most commonly botched — part of cap rate analysis. Sellers often present “pro forma” NOI based on optimistic assumptions. Always verify with actual trailing-12-month financials.

Start with gross scheduled rent (all units at 100% occupancy), then subtract:

• Vacancy and credit loss: Typically 5–10% of gross rents. Never assume 0% vacancy even in a hot market.
• Property taxes: Use actual assessed values, not the seller’s estimate. Reassessments after a sale can increase taxes significantly.
• Insurance: Get your own quote. Insurance costs have risen 20–40% in many markets since 2022.
• Property management: 8–12% of collected rents if you hire a manager. Even if self-managing, include this — your time has value.
• Maintenance and repairs: Budget 1% of property value annually as a baseline. Older properties need more.
• Capital expenditures reserve: Roof, HVAC, appliances, and major systems wear out. Budget $100–$200/unit/month as a reserve.

What you do not include: mortgage principal and interest, depreciation, income tax, or any personal expenses. Cap rate is a pre-financing metric.

What Is a Good Cap Rate?

The honest answer is: it depends. Cap rates vary by market, property type, asset class, and the broader interest rate environment. Trying to apply a single “good cap rate” benchmark across all real estate is like saying a P/E ratio of 20 is always good for any stock.

That said, here’s a general framework:

• 4–5%: Compressed cap rates typical of primary urban markets (NYC, LA, SF, Miami). Investors accept lower yields for lower risk, stronger appreciation, and liquidity.
• 5–7%: Mid-range. Secondary markets, suburban value-add, well-leased properties with some upside.
• 7–10%+: Higher cap rates in tertiary markets, older properties, challenged tenant mix, or property types with real operational risk (hotels, special-use).

According to CBRE’s 2025 US Cap Rate Survey, multifamily cap rates in primary markets averaged 5.0–5.5%, while secondary markets averaged 5.5–6.5%. Industrial real estate averaged 5.0–6.0% in primary markets — the lowest of any major asset class due to sustained e-commerce demand (JLL Capital Markets Research, 2025).

Cap Rate vs Cash-on-Cash Return vs ROI

These three metrics are related but measure different things. Understanding the difference prevents costly mistakes.

Cap Rate

Pre-financing income yield. Use it to compare properties and markets on a level playing field. It tells you what the asset earns, not what you earn.

Cash-on-Cash Return

Your actual annual cash flow divided by the cash you invested (down payment + closing costs). Unlike cap rate, it accounts for your mortgage. If your cap rate exceeds your mortgage interest rate (positive leverage), debt amplifies your cash-on-cash return above the cap rate. If rates are higher than the cap rate (negative leverage — common during high-rate environments), debt hurts your cash flow.

Return on Investment (ROI)

Total return including appreciation, principal paydown, and tax benefits over the full holding period. ROI is the most comprehensive measure but requires assumptions about future values and sale proceeds.

The Cap Rate Multiple

Flip the cap rate into a multiple and it becomes more intuitive. A 6% cap rate implies a value of 16.7× annual NOI (1 ÷ 0.06 = 16.7). This is sometimes called the “GIM” or “cap rate multiple.”

A 5% cap rate = 20× NOI. A 7% cap rate = 14.3× NOI. When cap rates compress from 6% to 5%, the same property’s implied value jumps from 16.7× to 20× its NOI — a 20% increase in value with no change in income. This is why rising property values in low-rate environments feel disconnected from rent growth.

According to NCREIF (2025), the average unleveraged return for commercial real estate over 20 years is approximately 8.8% annually, combining income return (roughly the cap rate) and appreciation. The split is typically 5–6% income return and 2.5–3.5% appreciation.

How Cap Rates Relate to Interest Rates

Cap rates and interest rates move together over long time horizons, but the relationship is imperfect. When the 10-year Treasury yield rises, investors demand higher cap rates to maintain a positive spread — pushing property values down. When rates fall, cap rates compress and values rise.

The typical “spread” between commercial real estate cap rates and the 10-year Treasury has historically been 150–250 basis points. When that spread narrows below 100 basis points (as it did in 2021–2022), real estate becomes expensive relative to bonds. When it widens above 300 basis points, real estate looks attractive.

This is why 2023–2025 was painful for commercial real estate: rates rose faster than cap rates expanded, creating negative leverage for many buyers and forcing sellers to accept lower prices to transact.

Frequently Asked Questions

What is a cap rate in real estate?

Cap rate (capitalization rate) is a metric that expresses a property’s annual net operating income (NOI) as a percentage of its purchase price or current market value. It tells you how much income a property generates relative to its cost, independent of financing. Formula: Cap Rate = NOI ÷ Property Value.

What is a good cap rate?

There is no universal “good” cap rate — it depends on market, property type, and risk tolerance. In primary markets (New York, Los Angeles, San Francisco), a 4.5–5.5% cap rate on multifamily is typical. In secondary markets, 5.5–7.0% is more common. Office and retail trade at higher cap rates (6.5–10%) to compensate for higher vacancy risk. Industrial is among the lowest at 5.0–6.0% due to strong demand. A higher cap rate means higher income relative to price — but usually signals more risk or a weaker market.

How do I calculate cap rate?

Step 1: Calculate NOI. NOI = Gross Rental Income − Operating Expenses (property taxes, insurance, maintenance, management fees, vacancy allowance). Do not subtract mortgage payments — cap rate is a pre-financing metric. Step 2: Divide NOI by the property value. Example: NOI of $24,000 ÷ Property Value of $500,000 = 4.8% cap rate.

What is the difference between cap rate and cash-on-cash return?

Cap rate ignores financing and measures a property’s intrinsic yield. Cash-on-cash return measures the actual cash income you receive on the cash you invested, after debt service. If you buy with a mortgage, your cash-on-cash return will differ from the cap rate depending on your loan terms. When your cap rate exceeds your mortgage rate (positive leverage), debt improves your cash-on-cash return. When mortgage rates exceed the cap rate (negative leverage), debt hurts cash flow.

Does a higher cap rate mean a better investment?

Not necessarily. A higher cap rate often reflects higher risk — weaker markets, older properties, higher vacancy, or more management-intensive tenants. Class A apartments in prime urban markets trade at 4.5% cap rates not because investors are satisfied with lower yields, but because those assets carry lower risk and stronger appreciation potential. Compare cap rates within the same market and property class. A 7% cap rate in a shrinking Midwest market may be less attractive than a 5% cap rate in a high-growth Sun Belt city.

How does cap rate affect property value?

Cap rate and property value move in opposite directions. When cap rates compress (fall), values rise — and vice versa. The implied value of a property is NOI ÷ Cap Rate. A property generating $50,000 NOI is worth $1,000,000 at a 5% cap rate but only $714,286 at a 7% cap rate. This is why declining interest rates drive real estate values up: investors accept lower cap rates when bond yields fall, pushing property prices higher.
