Free Cap Rate Calculator

Instantly determine the Capitalization Rate (Cap Rate) and Net Operating Income (NOI) of any commercial or residential property. Compare asset profitability across diverse submarkets on an unlevered, cash-neutral basis.

How Is Capitalization Rate (Cap Rate) Calculated?

Capitalization Rate (Cap Rate) is calculated by dividing a property's annual Net Operating Income (NOI) by its total purchase price or current market value, then multiplying by 100. It measures the unlevered annual rate of return an investor would earn on an all-cash purchase before mortgage financing.

Cap Rate (%) = (Net Operating Income ÷ Property Purchase Price) × 100
NOI (Numerator): Effective gross rent minus real property taxes, insurance, management fees, maintenance, and vacancy reserves. Mortgage debt service is strictly excluded.
Price / Value (Denominator): Total acquisition price, or appraised market valuation when determining exit yields.

Step-by-Step Worked Example ($650,000 Commercial Property)

Consider a commercial retail building acquisition listed for $650,000 with 3 storefront suites generating steady rental cash flow:

  • Gross Annual Scheduled Rent: $78,000 ($6,500 / month across 3 retail suites)
  • Property Taxes & Insurance: $11,400 / year
  • Property Management & Repairs: $12,000 / year
  • Total Annual Operating Expenses: $23,400 / year (30% OpEx ratio)
1. Net Operating Income (NOI): $78,000 − $23,400 = $54,600 / yr
2. Calculated Cap Rate: ($54,600 ÷ $650,000) × 100 = 8.40%

An 8.40% unlevered yield means the asset generates $54,600 in net operational earnings every year on a $650,000 all-cash investment before taking on any bank debt.

Who Relies on Cap Rate Analysis?

Commercial Brokers

Price retail, industrial, and multifamily listings accurately based on prevailing local submarket cap rate comps.

Syndicators & Funds

Screen institutional assets rapidly to determine if entry unlevered yields exceed fund hurdle thresholds.

Private Real Estate Investors

Compare cross-market residential and commercial opportunities on an unlevered, cash-neutral basis.

Top 5 Mistakes to Avoid in Cap Rate Underwriting

1. Subtracting Mortgage Debt Service from NOI: Cap Rate must remain 100% unlevered. Subtracting principal and interest payments from revenue distorts the calculation.
2. Trusting Seller Pro Forma Projections Over T12 Historicals: Brokers often present optimistic "pro forma" cap rates. Always underwrite in-place cap rates using verified Trailing 12-Month operating statements.
3. Applying National Cap Rates to Micro-Submarkets: A 5% cap rate might represent fair market value in a prime downtown metro core, but would represent massive overpayment in a secondary market where comps trade at 8.5%.
4. Ignoring Lease Rollover & Expiration Risk: A high 9% in-place cap rate is illusory if the sole anchor tenant has only 12 months remaining on their lease and intends to vacate.
5. Confusing Cap Rate with Cash-on-Cash Return: Cap Rate reflects all-cash yield on total property valuation; Cash-on-Cash return reflects the levered dividend yield on your actual out-of-pocket down payment.

Frequently Asked Questions About Cap Rates

How is Capitalization Rate (Cap Rate) calculated?

Cap Rate (%) = (Net Operating Income ÷ Property Purchase Price) × 100.

What is a good Cap Rate?

Cap rates typically range from 4% to 10%+, depending on property asset class, tenant creditworthiness, and submarket location.

Why does Cap Rate exclude debt service?

Excluding financing allows investors to compare the pure income productivity of competing assets on an equal footing.

How do interest rates affect cap rates?

Higher interest rates increase debt financing costs, requiring cap rates to expand to maintain positive leverage spreads.

What is the difference between Cap Rate and Cash-on-Cash Return?

Cap Rate evaluates unlevered return on total price; Cash-on-Cash Return evaluates levered return on your actual cash invested.
