Cash you need — and when it's due
Deposit + costsThe all-in figure above is your tax and buying fees. But the real cash you need from savings also includes your deposit — and it's not all due on the same day. Set your deposit below to see the true total and the payment timeline.
Assumes a 10% exchange deposit (or your full deposit if smaller). Your lender, not this tool, sets the minimum deposit it will accept. Excludes mortgage interest, moving and ongoing costs. Estimates only — confirm exact figures with your conveyancer.

- £250,001 to £925,000 contributes £16,000 at 5.0% in this scenario.
- Additional-property treatment can increase totals sharply at the same price, so stress-test offers before committing.
How to use this page well
This page is designed for additional-property surcharge stress-testing. Additional-property treatment can change the total sharply, so this page is useful for buy-to-let and second-home budgeting before offers are submitted.
Use the nearby-price comparison table and test fee assumptions with a contingency buffer. That gives a more realistic completion-cash range than a single point estimate.
In this range, threshold effects usually become more visible, so comparing nearby price points is particularly useful.
Practical checks before you offer
- Run the same price with a different buyer type before finalising your offer strategy.
- Keep fee assumptions realistic and update them as quotes arrive rather than waiting until exchange.
- Use the city and county pages for local-intent comparisons, but verify final figures with your conveyancer before completion.
Understanding the costs on a £570,000 purchase
The headline stamp duty figure is only part of what you need to have available at completion. On a £570,000 property, the all-in total is £49,699 once you add legal fees, your survey and any mortgage arrangement fee. That is the figure your solicitor will need you to have cleared and ready — not the deposit figure your mortgage lender quotes, and not just the tax.
Stamp duty (or LBTT in Scotland, LTT in Wales) is charged in progressive bands — only the slice of the price in each band is taxed at that rate, not the whole purchase price. So on a £570,000 property, the effective tax rate is 8.25%, which is lower than the headline marginal rate of 5.0% that applies to the top slice of the price.
Conveyancing fees cover your solicitor's legal work from instruction through to completion — title searches, Land Registry registration and the SDLT, LBTT or LTT return to HMRC, Revenue Scotland or the Welsh Revenue Authority. Quotes vary quite a bit depending on the property type, leasehold complications and the solicitor's location. The default of £1,200 used here is a reasonable mid-range estimate; open the advanced fee editor and replace it with a real quote before making any final budget decisions.
Average 2026 conveyancing quotes in the £500,001 to £600,000 band were £1,640 for a freehold purchase and £1,780 for a leasehold (Compare My Move), and the Land Registry fee at this price is £295 online. See conveyancing fees on a £570,000 home for every price band, each region and what a quote should include.
What the effective rate actually means
An effective rate of 8.25% means that across the whole £570,000 purchase price, 8.25% goes to property tax. The marginal rate of 5.0% is what applies to the last pound of the price, so it tells you what each £1,000 negotiated off is worth in tax. Because only the part of the price above a threshold is taxed at the higher rate, agreeing a price just under a threshold saves very little tax. The exception in England and Northern Ireland is first-time buyer relief, which is lost on the whole price once it goes over £500,000.
Checklist before you exchange
- Confirm you have the all-in completion sum (£49,699) available as cleared cash — not just the deposit your mortgage lender requires.
- Check whether you qualify as a first-time buyer under HMRC's definition; if you have ever owned a residential property anywhere in the world, FTB relief does not apply.
- If you own other property, confirm whether the 5% additional-property surcharge applies (England and Northern Ireland from October 2024). The surcharge is on the full purchase price. It can be refunded if you sell your previous main residence within 3 years; claim within 12 months of that sale (or of the SDLT filing date, if later).
- Get your conveyancing quote in writing before exchange, with VAT and every disbursement shown.
- Ask your mortgage broker whether there is a free valuation or cashback that offsets the arrangement fee, as this changes the net mortgage cost used in the all-in total.
FAQ
What does the total cost include at £570,000?
Property tax plus editable legal, survey and mortgage-fee assumptions, shown as one all-in planning estimate.
Should I include contingency?
Yes. A contingency buffer improves completion reliability, especially while quotes and timescales are still moving.
Can I compare scenarios quickly?
Yes. Switch buyer type and region in the same calculator panel to compare all-in totals.
Why does the all-in figure move more than tax alone?
At this price, legal, survey and lender fees can still materially change the completion cash figure even when tax is the headline number.
Is this final legal advice?
No. Confirm final figures with your conveyancer and official calculators.
