Real Estate Investment Calculators
Successful real estate investing comes down to knowing your numbers before you buy. Whether you are evaluating a rental property for the first time or comparing multiple deals, these calculators give you the return metrics that matter — cap rate, rental yield, and cash flow — so you can filter out bad deals quickly and underwrite good ones confidently.
The Cap Rate Calculator is the standard starting point for investment property analysis. Cap rate (net operating income divided by property value) lets you compare properties of different sizes and prices on an equal footing, independent of how they are financed. It is also how institutional investors and appraisers benchmark property values.
For rental investors focused on cash flow, the Rental Yield Calculator shows both gross and net yield on any property. Enter the property value, annual rent, and operating expenses to see your actual return after costs — not just the headline number a listing might advertise.

Key investment metrics explained
Cap rate = NOI / Property Value. It answers: if you paid all cash, what annual return would the property generate? A property with $24,000 NOI priced at $400,000 has a 6% cap rate. Cap rate is calculated before debt service, so it reflects the property's intrinsic income performance, not the investor's financing decisions.
Gross rental yield = Annual Rent / Property Value. A property renting for $2,500/month ($30,000/year) priced at $500,000 has a 6% gross yield. Net yield subtracts all operating costs first. If those costs total $8,000 per year, net yield drops to ($30,000 − $8,000) / $500,000 = 4.4%.
The 50% rule is a useful quick estimate: operating expenses on residential rentals typically run about 50% of gross rent. If a property collects $2,000/month, budget $1,000 for expenses, leaving $1,000 for debt service and cash flow. This rule doesn't replace a full analysis but it filters out obviously overpriced deals.
