What This Calculator Computes
Rent minus mortgage, taxes, insurance, maintenance, and management. Positive means money in your pocket each month.
Net Operating Income divided by purchase price. Compare properties regardless of financing. Many investors treat 5–8% as solid (a rule of thumb, not a guarantee).
Annual cash flow divided by cash invested (this calculator uses your down payment; add closing costs yourself if you want them included). Tells you how hard your dollars are working.
Purchase price divided by annual gross rent. Lower is better — a common rule of thumb is that a GRM under 10 is more likely to cash flow.
