Net Operating Income (NOI)
Paste numbers from your rent roll or pro forma — commas stay, dollar signs are stripped (e.g. $125,000).
NOI = all the income the property collects in a year, minus what it costs to run (taxes, insurance, repairs, management). It does not include the mortgage payment.
Cap Rate
Cap Rate = NOI ÷ purchase price. It's the unleveraged yield — what the property would return in year one if you paid all cash. Higher cap rate = cheaper price relative to income (but often more risk).
Cash-on-Cash Return (financing)
Cash-on-Cash = annual cash flow ÷ cash you actually invested (down payment + closing costs). It tells you the real return on the money out of your pocket once the mortgage is in place.
Cash-on-Cash & DSCR
DSCR (Debt Service Coverage Ratio) = NOI ÷ annual mortgage payments. It shows how comfortably the property's income covers the loan. 1.00× means it just barely covers; 1.20× means 20% cushion. Most commercial lenders want 1.20×–1.25× minimum.
Enter NOI and purchase price to see the quick fix.

How the cap rate calculator works
Cap Rate = NOI ÷ Purchase Price. It's the unlevered yield — the return you'd earn buying the property all-cash. A 6% cap rate means $60,000 of NOI per $1,000,000 of price. Use it to compare deals across markets and asset classes.
NOI calculator
NOI = (Gross Rent + Other Income) × (1 − Vacancy) − Operating Expenses. Operating expenses include property tax, insurance, management, repairs, utilities and reserves. NOI excludes mortgage payments, depreciation and income tax — that's the whole point. Two deals with different financing should be compared at the NOI line.
Cash-on-cash return calculator
Cash-on-Cash = Annual Cash Flow ÷ Cash Invested. Cash flow is NOI minus annual debt service; cash invested is down payment plus closing costs. This is the levered yield on the dollars you actually put in — most syndicators target 8%+ on stabilized deals and 12%+ on value-add.
DSCR for lender pre-screening
DSCR = NOI ÷ Annual Debt Service. Most US commercial lenders underwrite to DSCR ≥ 1.20×, life companies to 1.25–1.35×, and SBA 7(a) to 1.15× on owner-occupied. If your DSCR is below the threshold, the lender will require a bigger down payment until it clears.
