Analyze cash flow, ROI, cap rate and returns on any investment property

Analyze any rental property investment in 4 steps

Enter expected monthly rent and vacancy rate. Research comparable rents on Zillow, Rentometer, or local listings.
Include property tax, insurance, management fees, maintenance, and HOA. Don't underestimate โ surprises always happen.
Check cash flow, cap rate, cash-on-cash return, and total ROI. Compare to the benchmarks in the info section below.
A rental property calculator helps investors analyze the financial performance of a potential investment property. It considers all income, expenses, and financing to determine whether a property will generate positive cash flow and provide a good return on investment.
This calculator goes beyond simple cash flow to show you cap rate, cash-on-cash return, total ROI including equity buildup and appreciation, and a 5-year projection so you can make data-driven investment decisions.
Key concepts for evaluating investment properties
Positive cash flow means the property covers all expenses and still pays you. Even $200/month = $2,400/year passive income. Negative cash flow means you're paying out of pocket every month.
Quick screening: Monthly rent should be at least 1% of purchase price. $300K property should rent for $3,000+. Below 0.7% is usually a poor cash-flow investment.
Roughly 50% of gross rent goes to expenses (not counting mortgage). If rent is $2,200, expect ~$1,100 in expenses. Helps quickly estimate cash flow before deep analysis.
Put 25% down, control 100% of the asset. If property appreciates 4%, your $75K down payment earned $12K (16% return). Leverage multiplies returns โ and losses.
Set aside 1-2% of property value annually for maintenance. On a $300K property = $3,000-6,000/year. Major items (roof, HVAC, plumbing) can cost $5K-20K each.
Good school districts, low crime, job growth, and population growth drive both appreciation and rental demand. A great property in a bad area is a bad investment.

Cap Rate = Net Operating Income / Purchase Price
