How This Calculator Works

Cap rate measures a property's net operating income against its purchase price, independent of financing — useful for comparing deals regardless of down payment or loan terms.

Cash-on-cash return measures your annual cash flow against the actual cash you invested — your down payment plus closing costs — which reflects how your specific financing affects your real return.

Monthly cash flow is your rent minus your mortgage payment and operating expenses, including estimates for maintenance and vacancy — the number that tells you whether the property is putting money in your pocket each month or costing you money to hold.
