04 / CALCULATION

Understand the formula

NOI = annual income − vacancy − operating expenses

$42,000.00 − $2,000.00 − $10,000.00 = $30,000.00

Cap rate = NOI ÷ property value × 100

$30,000.00 ÷ $400,000.00 × 100 = 7.5%

Cap rate is an estimate. Figures stay in your browser; currency changes display only.

Frequently asked questions

What is a cap rate?

Capitalization rate compares annual net operating income (NOI) with property value: NOI divided by value, multiplied by 100.

How is NOI calculated here?

NOI equals annual rental income minus entered annual vacancy allowance and annual operating expenses.

Can I estimate property value from a target cap rate?

Yes. Choose the reverse mode; estimated value equals positive NOI divided by the positive target cap rate as a decimal.

What if expenses exceed income?

In forward mode, NOI and cap rate can be negative. Reverse valuation requires positive NOI to estimate a positive property value.

Do mortgage payments or income taxes affect NOI?

No. Mortgage payments, income taxes and depreciation are excluded from this operating-income calculation.

Are property amounts uploaded or currencies converted?

No. Calculations happen in browser memory. Currency only changes display; no exchange rate or upload is used.
