How this calculator works

Enter your property purchase price, expected monthly rent, and estimated annual costs. The calculator works out gross yield (annual rent ÷ purchase price) and net yield ((annual rent − costs) ÷ purchase price).

Before you use this tool

Rental yield tells you how much return you're getting on your property investment. Gross yield compares annual rent to purchase price; net yield accounts for running costs like maintenance, insurance, and void periods.
