Can You Afford This Home in the UK?

Buying a property in the UK carries costs and rules that catch many buyers off guard — particularly Stamp Duty Land Tax (SDLT), which can add tens of thousands of pounds to your purchase costs. A £600,000 home isn't just £600,000. After Stamp Duty, solicitor fees, survey costs, and mortgage arrangement fees, you're often looking at an additional £25,000–£40,000 just to complete the purchase. This calculator helps you understand your full UK mortgage picture. Enter your property value, deposit, and mortgage rate to see your monthly repayment under either repayment or interest-only terms. The calculator automatically computes Stamp Duty across all rate bands — including first-time buyer relief up to £625,000. It also shows your Loan-to-Value (LTV) ratio, which directly determines which mortgage rates you'll qualify for (60%, 75%, 85%, 90%, or 95% LTV products carry meaningfully different rates). First-time buyers benefit from Stamp Duty relief on properties up to £625,000, paying 0% on the first £425,000 and 5% on the remainder. This can save up to £11,250 compared to a standard buyer on the same property — a meaningful advantage that this calculator makes explicit. Whether you're buying in London, Manchester, Bristol, or Edinburgh, get a realistic view of your upfront costs and monthly commitment before you start making offers.
