Open toolFrequently asked questions
- Are these calculators free?
- Yes, all calculators are completely free to use with no signup required. Use them as many times as you like — there are no limits or hidden charges.
- How accurate are the calculations?
- The stamp duty calculators use the SDLT, LBTT and LTT rates currently in force; the income tax and National Insurance calculators name the tax year they use on their own page. Running cost estimates (council tax, energy, insurance) are based on UK averages and may vary by location and property type.
- What tax year do the calculators use?
- The stamp duty calculators use the SDLT rates in force since 1 April 2025 (first-time buyer threshold £300,000, additional property surcharge 5%). Calculators built on income tax, National Insurance or capital gains rates name the tax year they use on their own page.
- Do I need to create an account?
- No. All tools work without signing up — including the AI-powered renter tools (tenancy scanner, tenant rights, rent negotiation) and the AI property valuation. Analysing a Rightmove, Zoopla or OnTheMarket listing is different: that happens in the HomeThink browser extension, which needs a free account. The Free report costs nothing; the Pro report is part of Pro.
