How to use this buy-to-let calculator

This calculator helps UK property investors quickly assess whether a buy-to-let deal is financially viable. Adjust the purchase price, expected rent, mortgage rate, deposit percentage, and refurbishment budget to see how your returns change in real-time.

Gross yield is the annual rent divided by the purchase price. Most investors target 6% or above for a strong BTL deal. Net yield factors in running costs (insurance, maintenance, management fees, and void periods) plus mortgage payments.

DSCR (Debt Service Coverage Ratio) measures whether your rental income covers the mortgage. Lenders typically require a DSCR of 1.25 or higher. Below 1.0 means the rent doesn't cover the mortgage payment.
