Real Estate Calculators
Choose the right tool for your deal
Free calculators for rental cash flow, cap rate, financing, BRRRR, STRs, and property comparison.
Free rental property analysis tools for investors
Use this calculator library to evaluate rental properties before you make an offer, refinance a loan, compare two deals, or estimate long-term equity growth. Each tool focuses on a specific real estate investing question, from monthly cash flow and net operating income to DSCR, cap rate, cash-on-cash return, mortgage amortization, and short-term rental performance.
Start with the rental property cash flow calculator when you need a full deal overview. Use the cap rate, DSCR, mortgage, appreciation, and comparison tools when you want to isolate one part of the analysis. The calculators run in your browser, use transparent formulas, and are designed for planning and education rather than lender, tax, legal, or investment advice.

Open calculatorWhich calculator should you use first?
If you are analyzing a buy-and-hold rental, begin with cash flow. That gives you income, vacancy, expenses, financing, NOI, cap rate, DSCR, and return metrics in one place. If you already know the income and value, use the cap rate calculator to compare the property against similar local deals.
For financing decisions, use the mortgage calculator and DSCR calculator together. For strategy-specific deals, use the BRRRR, house hacking, short-term rental, UK buy-to-let, or appreciation calculators. When two properties look close, the comparison tool helps organize the tradeoffs side by side.
