# Cap Rate Calculator

Calculate capitalization rate, NOI, and gross rent multiplier for rental properties. Evaluate real estate investments with our free cap rate calculator.

## What this calculates

Evaluate real estate investments with our free cap rate calculator. Enter the property value, annual income, expenses, and vacancy rate to calculate Net Operating Income, capitalization rate, gross rent multiplier, and cash-on-cash return.

## Inputs

- **Property Value** ($) — min 0 — The current market value or purchase price of the property.
- **Annual Gross Income** ($) — min 0 — Total annual rental income if fully occupied.
- **Annual Operating Expenses** ($) — min 0 — Total annual expenses (property tax, insurance, maintenance, management, etc.).
- **Vacancy Rate** (%) — min 0, max 100 — The expected vacancy rate as a percentage of gross income.
- **Down Payment (optional)** ($) — min 0 — Enter your down payment to calculate cash-on-cash return.

## Outputs

- **Net Operating Income (NOI)** — formatted as currency — Annual gross income minus vacancy loss and operating expenses.
- **Cap Rate** — formatted as percentage — NOI divided by property value. Higher cap rates indicate higher returns but often more risk.
- **Gross Rent Multiplier (GRM)** — Property value divided by annual gross income. Lower GRM suggests better value.
- **Cash-on-Cash Return** — formatted as percentage — NOI divided by down payment (only if down payment is provided).

## Details

The capitalization rate (cap rate) is the most widely used metric for evaluating the return potential of income-producing real estate. The formula is: Cap Rate = Net Operating Income (NOI) / Property Value. NOI is calculated as gross rental income minus vacancy losses and operating expenses (but before mortgage payments, depreciation, and income taxes).

Cap rates vary significantly by property type, location, and market conditions. Class A properties in major cities might trade at 3-5% cap rates (lower return but lower risk), while Class C properties in secondary markets might offer 8-12% cap rates (higher return, higher risk). A 'good' cap rate depends on the investor's risk tolerance and alternative investments. As a general rule, the cap rate should exceed the risk-free rate (Treasury yields) by a meaningful margin.

The Gross Rent Multiplier (GRM = Property Value / Annual Gross Income) is a simpler metric that ignores expenses but provides a quick comparison tool. A lower GRM suggests better value. Cash-on-cash return (NOI / Cash Invested) measures the return on actual cash invested, accounting for leverage, and is useful for comparing investments with different financing structures.

## Frequently Asked Questions

**Q: What is a good cap rate?**

A: It depends on the market, property type, and risk. In major cities, cap rates of 4-6% are common. In smaller markets, 7-10% is typical. Higher cap rates mean higher potential returns but usually indicate higher risk. A cap rate significantly below prevailing rates may mean the property is overpriced; significantly above may indicate hidden problems.

**Q: What is Net Operating Income (NOI)?**

A: NOI is the annual income from a property after deducting all operating expenses but before mortgage payments, depreciation, and income taxes. It includes rental income minus vacancy losses, property taxes, insurance, maintenance, property management fees, and utilities paid by the landlord. NOI is the foundation for cap rate calculation.

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

A: Cap rate measures the property's return as if it were purchased with all cash (NOI / Property Value). Cash-on-cash return measures the return on your actual cash invested (Annual Cash Flow After Debt Service / Cash Invested). With leverage (a mortgage), cash-on-cash return can be higher or lower than the cap rate depending on the interest rate and terms.
