Cap Rate Calculator

Calculate the capitalization rate for a rental investment property.

How this is calculated
Cap rate = (Annual rental income − Annual operating expenses) ÷ Property value × 100

Assumptions used in this calculation

  • NOI excludes financing: Net operating income is calculated before any mortgage payment, the standard convention for comparing properties independent of how they're financed.
  • Rental income assumed effective: Annual rental income entered is treated as already accounting for expected vacancy. If you're entering gross potential rent, reduce it first or add a vacancy allowance to operating expenses.

About this calculator

The cap rate calculator finds the capitalization rate, net operating income divided by property value, a standard metric investors use to compare rental properties independent of financing.

Worked example

₹60L property, ₹4.8L rental income, ₹96,000 expenses

Result: Cap rate = 6.4%
