Understanding Cap Rate
By JC Pacific Corp Last updated 2026-10-02
Cap rate, short for capitalization rate, is net operating income divided by purchase price, expressed as a percentage. It measures the yield a property produces before financing, which makes it useful for comparing properties on a level playing field.
Run the numbers
Model purchase price, rent, expenses, and financing to estimate cash flow and returns.
Open the Rental Property CalculatorHow to Calculate Cap Rate
First calculate net operating income (NOI): gross annual income minus vacancy allowance minus operating expenses, before the mortgage payment. Then divide NOI by the purchase price (or current value) and multiply by 100.
Example: a property with $60,000 annual NOI purchased for $750,000 has a cap rate of 8 percent. The rental property calculator computes NOI and cap rate from your inputs.
What Cap Rate Tells You
Cap rate lets you compare properties regardless of financing, because it ignores the loan entirely. Higher cap rates usually mean higher yield and often higher risk, older properties, or weaker markets. Lower cap rates often appear in strong, expensive markets where buyers accept lower yield for stability and appreciation.
What Cap Rate Does Not Tell You
- It ignores financing, so it is not your return on invested cash
- It does not account for appreciation or depreciation
- It depends entirely on the income and expense assumptions you use
- It does not measure risk, condition, or market quality by itself
Use cap rate as one comparison tool, not the final answer. Pair it with cash-on-cash return, which measures your actual return on cash invested.
Frequently Asked Questions
What is a good cap rate in California?
There is no universal good number. Cap rates vary by market, property type, and risk, and California's expensive coastal markets often trade at lower cap rates than inland markets. Compare properties in the same market on the same assumptions.
Is a higher cap rate always better?
No. Higher cap rates can signal higher risk, older buildings, or weaker tenant demand. A lower cap rate in a strong market may produce better total results over time.
Does cap rate include the mortgage?
No. Cap rate is calculated before debt service. That is its strength for comparison and also its limit, since your actual return depends on how you finance.
