What is cash-on-cash return in real estate?

Cash-on-cash return measures the annual pre-tax cash flow as a percentage of the total cash invested (down payment + closing costs). A 10% cash-on-cash return means you earn $10,000/year on a $100,000 investment. The real estate calculator computes this automatically.

How does the real estate calculator compute cap rate?

Cap rate equals Net Operating Income divided by the purchase price. NOI is annual rental income minus operating expenses (excluding mortgage). A $300,000 property with $24,000 NOI has an 8% cap rate. The real estate calculator handles the full calculation.

What is a good cap rate for an investment property?

Cap rates vary by market — 4-6% is common in major cities, while secondary markets may offer 7-10%. Higher cap rates generally mean higher risk. Use the real estate calculator to compare properties across different price points and rental incomes.

What expenses should I include in the real estate calculator?

Include property taxes, insurance, property management fees, maintenance, HOA fees, vacancy reserves, and any other recurring costs. The real estate calculator provides a monthly expenses field where you can enter total operating expenses excluding the mortgage.

How does appreciation affect real estate ROI?

The real estate calculator includes an annual appreciation rate to project property value growth. Historically, U.S. home prices appreciate 3-5% annually. Combined with rental cash flow and mortgage paydown, total ROI on leveraged real estate can exceed 15-20% annually.

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.
