Instant, accurate figures for property transaction tax and mortgage repayments — no sign-up, no spreadsheet, updated for current rates in every UK nation.
Whichever UK nation you're buying in, you only pay the higher rate on the slice of the price that falls within each band, the same way income tax works. Switch nations above to see how the steps change. Your property's price determines how far up the stairs you go — but you're only charged the step-rate for the portion in that step.
Short, practical explainers that go beyond what the calculator alone can tell you.
How much extra you'll pay on a second home or buy-to-let, how refunds work if you're replacing your main residence, and a full worked example.

Read the guide →Before an offer is even accepted, two figures decide whether a purchase is viable: the one-off tax bill due on completion (stamp duty), and the recurring monthly cost of the debt (the mortgage). Everything else in a purchase — surveys, legal fees, removals — is comparatively small and predictable. Get these two numbers right early and there are no unpleasant surprises at exchange.
Buying a second home, a buy-to-let, or any property while already owning another triggers a surcharge of 5 percentage points on top of standard rates, on the entire price — not just the amount above the first threshold. This applies even if the additional property is the cheaper of the two.
Yes — up to £300,000, first-time buyers pay no stamp duty at all. Between £300,001 and £500,000, they pay 5% on the portion above £300,000. Above £500,000, the relief is lost entirely and standard rates apply to the full price.
Separately, and upfront — usually via your solicitor on completion day, out of your own funds (it isn't rolled into your mortgage).
Yes — use the nation tabs above the calculator. Scotland charges Land and Buildings Transaction Tax (LBTT) and Wales charges Land Transaction Tax (LTT), both with different bands and rates to SDLT, and both are built into the calculator.
Rates move with the base rate and lender margins, so check a current best-buy table before relying on the default figure — the calculator will do the maths correctly for any rate you enter.
