Investment & Rental Calculators

Check a rental property before you buy: gross yield, net yield and cash flow.

Rental Yield Calculator

Work out gross yield, net yield and monthly cash flow for a buy-to-let or rental property from price, rent and running costs.

Key rental metrics

Gross yield is a quick top-line comparison. Net yield subtracts running costs, so it shows what the property earns before any mortgage. Cash flow subtracts the mortgage as well and tells you whether the property pays for itself each month.

These are pre-tax estimates built on the figures you enter. Vacancy, repairs and rent changes can move the result, so treat the output as a filter, not a guarantee.
