What This Calculator Computes

Monthly Cash Flow

Rent minus mortgage, taxes, insurance, maintenance, and management. Positive means money in your pocket each month.

Cap Rate

Net Operating Income divided by purchase price. Compare properties regardless of financing. 5-8% is generally solid.

Cash-on-Cash Return

Annual cash flow divided by cash invested (down payment + closing costs). Tells you how hard your dollars are working.

Gross Rent Multiplier

Purchase price divided by annual gross rent. Lower is better — a GRM under 10 usually cash flows positively.
