Real investors do not rely solely on quick online estimates or free mortgage apps. They use detailed numbers to understand how a property will actually perform before making a decision.

This calculator gives you everything you need to analyze a deal in one place, including financing, monthly payments, income, expenses, cash flow, cash-on-cash return, equity growth, and long-term projections. Keep it simple for a quick mortgage or cash-flow calculation, or go deeper and customize the assumptions to fully evaluate a more complex investment opportunity.
