Stamp Duty Calculator

Stamp Duty Calculator

Enter the property price and tell us your buying situation, and you’ll get an instant estimate of what you’re likely to owe. It’s based on current HMRC rates, but it’s still just an estimate, not a figure you can rely on for exchange, so treat it as a starting point rather than the final word.

How This Calculator Works

You put in the property price, tell it whether you’re a standard buyer, a first-time buyer, or buying an additional property, and tick a box if you’re not a UK resident. It works out your Stamp Duty the same way HMRC does, in bands, applying the right rate to each slice of the price rather than one flat rate on the whole amount.

If you want to understand where these rates actually come from, or see the full worked examples by hand, our Stamp Duty Guide covers all of it in detail, including the rules around refunds, exemptions, and what happens if you’re transferring a property rather than buying one outright.

What This Estimate Doesn’t Include

This calculator is built for the common, straightforward cases: buying a home as a standard buyer, a first-time buyer, or someone adding a second property. It won’t get you the right answer if your situation is more unusual, for example:

  • You’re replacing your main residence and might be exempt from the second-home surcharge, or eligible for a refund if you’ve already paid it.
  • You’re inheriting a property, receiving one as a gift, or transferring a share to a partner or family member, since none of these work like a normal purchase.
  • You’re buying through Shared Ownership, where Stamp Duty can be calculated differently depending on how you choose to pay it.
  • Your purchase involves anything beyond a simple cash price, like taking on someone else’s mortgage debt as part of the deal.

If any of that sounds like you, it’s worth getting an actual figure from us rather than relying on the calculator.

What Should You Do With This Number?

Treat it as a working estimate for budgeting, not a final figure. Your solicitor will confirm the exact amount as part of your purchase, and it’s worth checking with a broker early on too, since Stamp Duty is one of several costs that affects how much you need upfront alongside your deposit.

Frequently asked questions

Yes. Stamp Duty rates are set nationally for England, so they’re exactly the same in Slough as anywhere else in the country. Where working with a local broker actually helps is in getting your overall costs right for the local market, not the Stamp Duty rate itself.

Because the two use genuinely different rate bands, not just a discount on the same number. First-time buyers pay nothing on the first £300,000 rather than £125,000, which is why the gap between the two figures can be a few thousand pounds even on a fairly ordinary property price.

As a starting point, yes. As a final number to plan your exact funds around, no. Get your solicitor or broker to confirm the real figure once you’re closer to exchanging, especially if your situation isn’t a straightforward purchase.
