How to Use the Cap Rate Analyzer

What does this tool calculate?

Three core investor metrics: Net Operating Income (NOI), Capitalization Rate (Cap Rate), and Gross Rent Multiplier (GRM) — plus an optional Debt Service Coverage Ratio (DSCR) if you enter a loan payment.

What do I need to enter?

Purchase price, gross annual rental income, any other income (parking, laundry, storage), your expected vacancy rate, and itemized annual operating expenses (taxes, insurance, maintenance, management, utilities, HOA, reserves). Add annual debt service if you want your DSCR calculated too.

How is Cap Rate calculated?

Cap Rate = (Net Operating Income ÷ Purchase Price) × 100. NOI is your effective gross income (rent + other income, minus vacancy loss) minus total operating expenses. A higher Cap Rate generally means higher potential yield — but often comes with higher risk.

How is GRM calculated, and why does it matter?

GRM = Purchase Price ÷ Gross Annual Rental Income. It's a quick, rough screening ratio — lower generally means better value relative to rent, but unlike Cap Rate, it ignores operating expenses entirely.

Can I compare multiple properties?

Yes. Save up to 3 property scenarios and view their NOI, Cap Rate, GRM, and DSCR side-by-side in the comparison table to quickly spot the strongest deal.
