Commercial real estate analysis starts with one number: the capitalization rate. Every CRE investor, broker, and lender uses it. This guide shows you exactly how to calculate it, what it means, and what benchmarks to use in 2026.

What Is Cap Rate?

The capitalization rate (cap rate) measures the expected annual return on a commercial property, assuming an all-cash purchase. It strips out financing, tax effects, and appreciation — giving you a clean, comparable yield.

Formula:

Cap Rate = Net Operating Income (NOI) / Property Value

Or flipped to solve for value:

Property Value = NOI / Cap Rate

How to Calculate It: Step by Step

Step 1: Calculate Gross Rental Income Add up all annual rents across all tenants or units at 100% occupancy.

Step 2: Apply Vacancy & Collection Loss Subtract an estimated vacancy factor. For most CRE assets, 5–10% is standard; office may run higher in 2026 given hybrid work patterns.

Step 3: Calculate Effective Gross Income (EGI) EGI = Gross Rental Income × (1 − Vacancy Rate)

Step 4: Calculate Net Operating Income (NOI) Subtract all operating expenses from EGI:

What NOI does NOT include: mortgage payments, depreciation, income taxes, or capital improvements.

Step 5: Divide NOI by Purchase Price

Cap Rate = NOI / Purchase Price

Worked Example

A 10,000 sq ft industrial building in Dallas, TX:

ItemAmount
Gross Rent (NNN lease)$120,000 / yr
Vacancy (5%)−$6,000
Effective Gross Income$114,000
Operating Expenses−$18,000
Net Operating Income$96,000
Purchase Price$1,600,000
Cap Rate6.0%

A 6.0% cap rate on an NNN industrial asset in Dallas is in line with the 5.5–6.5% range for stabilized industrial in secondary Sun Belt markets in 2026.

What Moves Cap Rates

Interest Rates: The 10-year Treasury is the benchmark. When rates rise, cap rates follow (eventually). In 2026, the 10-year sits around 4.5%, which keeps many property types under cap rate compression pressure.

Market Conditions: Primary markets (NYC, LA, SF) compress cap rates 50–150 bps vs. secondary/tertiary. Denver, Phoenix, and Nashville industrial assets now trade within 50 bps of gateway markets.

Lease Structure: NNN leases (tenant pays taxes, insurance, maintenance) command 50–100 bps lower cap rates than gross leases because the landlord's cost exposure is nearly zero.

Tenant Credit: A Walgreens or Amazon single-tenant NNN commands sub-5% cap rates. A local pizza shop in the same building trades at 7%+.

Lease Term Remaining: A 12-year term trades at a premium to a 3-year term. Rollover risk is priced in.

How AI Tools Are Changing CRE Analysis

Modern CRE investors use AI advisors to run comp analysis across markets in minutes. Stack Network's Business Advisor can pull sector benchmarks, compare cap rates across 18 verticals, and flag where spreads vs. risk-free rates are compressing or expanding. The days of building this manually in Excel are ending.

Bottom Line

Cap rate is a tool, not a verdict. A 6% cap rate in a primary industrial market beats a 9% cap rate in a tertiary office market any day — the numbers only mean something in context. Use the formula, benchmark against current data, and stress-test your NOI assumptions before you underwrite any deal.
