What is Rental Yield Calculator?
A rental yield calculator estimates how much income a property can generate relative to its price and the cash you invest. It starts with the purchase price and expected monthly rent to compute the gross rental yield, then layers in operating expenses, vacancy, and mortgage financing to produce net operating income, cap rate, net yield, and cash-on-cash return. Investors use these figures to compare properties across different price points and financing structures before making an offer. This free tool runs entirely in your browser - enter the numbers, adjust vacancy or loan terms, and see every return metric update instantly.

Frequently Asked Questions
What is the difference between gross yield and net yield?
Gross yield divides annual rent by the property price and ignores all costs, giving a quick market comparison. Net yield subtracts operating expenses and mortgage payments from the rent first, so it reflects the actual return you can expect after the property's real costs.
How is the cap rate different from cash-on-cash return?
Cap rate uses net operating income (rent minus operating expenses) divided by the full property price, so it ignores financing and compares properties on equal footing. Cash-on-cash return divides annual cash flow after mortgage payments by the cash you actually invested (down payment plus closing costs), showing the return on your own money.
Does the calculator include mortgage payments?
Yes. Enter your down payment percentage, interest rate, and loan term, and the tool computes an amortized monthly payment using the standard loan formula, then deducts it to find your net yield and cash-on-cash return.
