Cap Rate Calculator (Real Estate Capitalization Rate & NOI)
Calculate capitalization rate (Cap Rate) and Net Operating Income (NOI) for property investments.
TL;DR: Cap Rate Calculator computes the Capitalization Rate of real estate investments using Net Operating Income (NOI) divided by current property market value or acquisition cost.
What Is Capitalization Rate (Cap Rate) and How Is It Calculated in Real Estate?
Capitalization Rate (Cap Rate) measures the unleveraged annual rate of return on a real estate investment. It is calculated using the formula: Cap Rate = (Net Operating Income / Property Current Market Value) × 100%. A higher cap rate indicates higher annual rental yields relative to property price.

Mathematical Formula & Equations
Where NOI is gross annual rental income minus all property operating expenses (taxes, maintenance, insurance, vacancy allowance, property management fees).
Calculation Example
A commercial property generating $60,000 gross rent with $18,000 annual operating expenses (NOI = $42,000) purchased for $600,000: $$\text{Cap Rate} = \frac{42000}{600000} \times 100\% = 7.0\%$$

Frequently Asked Questions
- In most real estate markets, a cap rate between 4% and 8% is considered healthy. High-demand metropolitan areas may trade at 3%–5% cap rates, while higher-risk secondary markets often yield 7%–10%.
- Net Operating Income (NOI) equals Gross Operating Income (all rental revenue minus vacancy loss) minus all operating expenses (taxes, insurance, repairs, management). Mortgage debt service is excluded from NOI.
- No. Cap rate measures property return assuming an all-cash purchase, allowing investors to objectively compare property fundamentals without the distortion of varying loan terms.
- Cap Rate evaluates total property yield independent of financing, whereas Cash-on-Cash return measures the cash yield specifically on the actual down payment and cash invested after deducting mortgage payments.
- Because Property Value = NOI / Cap Rate. When investors are willing to accept lower yields in strong markets (compressed cap rates), property market valuations rise.
- Cap rate evaluates purely the unleveraged operating performance of an asset by dividing Net Operating Income (NOI) by total property value, regardless of how an investor finances the purchase.
