How to Use This Mortgage Calculator
This mortgage calculator goes beyond simple payment math. Enter your purchase price, down payment percentage, interest rate, and loan term to get instant results. The rent slider adds investment analysis — showing you cash flow, cap rate, and cash-on-cash return simultaneously.
Understanding Your Mortgage Metrics
Monthly Payment covers principal and interest only. Budget an additional 1-2% of property value annually for taxes, insurance, and maintenance.
Cap Rate (Capitalization Rate) is the annual net operating income divided by the property value. A cap rate above 6% is generally considered acceptable for residential investment properties, though this varies significantly by market.
Cash-on-Cash Return measures the annual cash flow relative to your cash invested (down payment). Experienced investors typically target 8-12% or higher.
Debt Coverage Ratio (DCR) compares rental income to mortgage payments. Most lenders require a DCR of at least 1.25, meaning rental income must be 25% higher than the mortgage payment.
