Calculate cap rate & real estate with real-time mathematical breakdowns, amortization schedules, and instant reporting.
What is the Cap Rate & Real Estate?
Capitalization rate calculation measures the unleveraged, annual rate of return generated on commercial or residential income-producing real estate property assets. It divides property Net Operating Income (NOI)—gross collected rental revenues minus operating expenditures and structural vacancy—by current market valuation or purchase acquisition price. This provides real estate investors with a standardized valuation metric to compare property profitability and risk profiles across distinct geographic real estate markets.
Capitalization Rate (Cap Rate) is one of the most vital metrics used by commercial and residential real estate investors to evaluate market value and potential investment yield. Cap Rate isolates a property's fundamental income-generating ability independent of financing structure, allowing side-by-side comparison across different properties.
Our Cap Rate & Real Estate Calculator automatically computes your Net Operating Income (NOI) by subtracting vacancy and operating expenses from gross rental revenue. Adjusting purchase prices and expense ratios gives you immediate visibility into asset valuation and risk-adjusted return on investment.

The Capitalization Rate Formula
If a residential rental property generates $30,000 in NOI and costs $400,000 to purchase, the Cap Rate is exactly 7.5% ($30,000 / $400,000 = 0.075).
