How This Real Estate Calculator Works
The real estate calculator models a rental investment property by computing the mortgage payment, subtracting expenses from rental income, and deriving key metrics. It calculates monthly cash flow (rent minus mortgage minus expenses), net operating income (annual rent minus annual expenses), and cap rate (NOI divided by purchase price).
Cash-on-cash return shows your annual cash flow as a percentage of the cash you actually invested — the down payment. For example, a $250,000 property with 20% down generating $400/month cash flow yields a 9.6% cash-on-cash return. The real estate calculator makes this math effortless.
The bar chart shows projected annual cash flow over time, factoring in appreciation. As property values rise, your equity grows even if cash flow stays flat. The real estate calculator gives you a 10-year projection to evaluate the full picture.

3 Keys to Profitable Real Estate
Buy Right
The 1% rule says monthly rent should equal at least 1% of the purchase price. A $200,000 property should rent for $2,000+. Run every deal through the real estate calculator before making an offer to confirm the numbers work.
Control Expenses
Operating expenses typically run 35-50% of gross rent. Property management (8-10%), maintenance (5-10%), vacancy (5-8%), and insurance eat into returns. The real estate calculator helps you model realistic expense scenarios.
Leverage Wisely
A 20-25% down payment balances leverage with cash flow. Too little equity means higher payments that can turn cash flow negative. Too much equity reduces your return on investment. The real estate calculator shows the optimal balance.
