Profit after everything, not just the mortgage.
Most calculators stop at rent minus mortgage. NestInsights counts what you'll actually pay, on the tax rules for the day you complete.
- Stamp duty or Welsh LTT, with the higher rates for additional homes and companies
- Legal, mortgage and broker fees, in the cash you need
- Letting agent, repairs and empty weeks, every month
- Section 24 and your income tax band
- Your own name or a company, side by side after tax
Cash you need to buy

Questions
What's free?
The full deal calculator, every tax rule and up to 3 saved deals, for as long as you like. You don't need a card, and you don't need an account to try a deal.
Can I cancel Pro?
Yes, at any time, from your account page. Pro keeps working until the end of the month or year you've paid for, and nothing you've saved is deleted.
Does it work for Wales?
Yes. A Welsh postcode switches the deal to Land Transaction Tax, with Wales's own rates and higher rates for additional homes. Scotland and Northern Ireland have different taxes, so they aren't covered.
What if I buy through a company?
Pick a limited company as the buyer, or compare both: the full breakdown puts owning in your own name next to a company, with corporation tax, dividend tax and the higher stamp duty a company pays.
Where do the numbers come from?
Stamp duty, Land Transaction Tax, income tax and corporation tax follow the published HMRC and Welsh Revenue Authority rates. Each rule is dated, so the rules for your completion date are used. The results are estimates to help you decide, not financial advice.
