Cap Rate Calculator

Cap rate is useful, but only if you know what it leaves out.

Dealarc helps investors use cap rate as a fast screening metric while keeping the rest of the underwriting picture in view, including NOI quality, debt service, and hold-period returns.

Start with NOI

Cap rate only works when income and operating expenses are realistic. Inflated NOI creates misleading cap rates.

Ignore debt carefully

Cap rate is pre-financing, which makes it useful for comparing assets but incomplete for investor-level returns.

Use it as a first filter

Strong operators use cap rate to screen deals quickly, then move into cash flow, DSCR, and IRR analysis.

What a cap rate calculator should tell you

Cap rate is one of the fastest ways to compare properties, but it is not the same thing as investor return. A reliable calculator should help you understand how net operating income translates into a cap rate and how that metric fits into a broader underwriting process.

Cap rate formula

Cap rate = NOI / property value

If a property generates $60,000 in NOI on a $1,000,000 purchase, the cap rate is 6%.

What cap rate misses

  • Debt service and leverage
  • Capital expenditures
  • Hold period and sale assumptions
  • Refinance strategy
Use cap rate to compare opportunity quality, not to replace full underwriting. Dealarc is built to take investors beyond the first filter into cash flow, DSCR, and IRR.

Cap rate calculator FAQ

What is cap rate?

Cap rate is NOI divided by property value or purchase price. It helps investors compare assets before financing effects are considered.

Does cap rate include financing?

No. Cap rate is a pre-debt metric, which is why two buyers with different financing can experience very different returns on the same property.

What is a good cap rate?

It depends on asset type, market, risk, and growth expectations. Higher is not always better if the income is unstable or the market carries more risk.
