UK Calculators by Audience — Frequently Asked Questions
Which calculators are most useful for freelancers and contractors?
Freelancers and contractors should prioritise: the Self-Employed Tax Calculator (income tax + Class 4 NI on profits), the Limited Company vs Sole Trader comparison, the IR35 take-home calculator (inside vs outside IR35 difference), the VAT registration threshold checker (£90,000 turnover), and the Dividend vs Salary optimiser for limited company directors. Also useful: the Pension Annual Allowance calculator (contractor pensions are often the most tax-efficient saving vehicle), and the Student Loan repayment checker if you have a Plan 2 or Plan 5 loan.
What calculators do accountants and finance professionals use most on CalcHub?
Accountants and finance professionals tend to use: the Tax Year Comparison tool (year-on-year rate changes), Income Tax by Salary (quick reference for common salary points), the Dividend Tax calculator, Capital Gains Tax by asset type, Pension Annual Allowance worked examples (especially tapered AA for high earners), Stamp Duty for property transactions, and the IR35 comparison. The CalcHub API is also available for firms wanting to embed or query calculations programmatically.
Are there calculators specifically for landlords?
Yes — the landlord and property investor audience hub includes: Stamp Duty with the additional-property surcharge, Rental Income Tax calculator (Section 24 mortgage interest restriction), Capital Gains Tax on residential property (higher CGT rates apply: 18%/24%), Wear and Tear allowance explainer, and the Buy-to-Let vs Pension comparison tool. The 60-day CGT reporting window for residential property sales is also covered in the guides section.

What calculators are useful for NHS or healthcare workers?
Healthcare workers have specific financial considerations: the NHS Pension calculator (1995/2008/2015 scheme comparisons, McCloud remedy impact), the Take-Home Pay calculator with student loan Plan 1 (common for nurses and AHPs), the Annual Allowance tool (clinicians frequently breach the AA due to DB pension growth), the Locum vs PAYE calculator, and the Scotland take-home calculator (many locums work across borders). The pension tax charge for NHS staff is a significant planning issue covered in the guides.
Are there calculators for small business owners?
Small business owners should use: the Limited Company Salary + Dividend optimiser, the VAT calculator and registration threshold checker, the Corporation Tax calculator, the Business Asset Disposal Relief (BADR) tool for CGT on business sale, the Employment Allowance checker (up to £5,000 reduction in employer NI), and the R&D Tax Credit estimator. The Budget hub also covers Autumn Statement and Spring Budget changes that affect small businesses (employer NI thresholds, Corporation Tax rate, expensing rules).
Which calculators are most useful for families?
Families benefit from: the Take-Home Pay calculator with Child Benefit HICBC check (both parents should model this if either earns over £60,000), the Childcare Calculator (Tax-Free Childcare vs Universal Credit childcare element), the Marriage Allowance checker, the Stamp Duty first-time buyer calculator, the Help to Buy / shared ownership guide, and the Student Loan repayment planner (for planning your children's future finances or your own if recently graduated). The Maternity Pay calculator (SMP rates and employer top-up modelling) is useful for expectant parents.
What does the "new to the UK" audience hub include?
The "new to the UK" hub covers the financial and tax topics most important when arriving in the UK: understanding the PAYE system and your tax code, National Insurance and how it affects State Pension entitlement, how UK bank accounts and credit files work, the National Living Wage (your minimum legal entitlement), Council Tax and how to register, and the Skilled Worker visa salary thresholds. We also cover how ISAs work for savers new to the UK and the remittance basis for those with overseas income.
Are there calculators for retirees and those approaching retirement?
Yes — the retiree hub focuses on: the State Pension forecast (check your NI record via gov.uk), the Private Pension drawdown calculator, the Pension vs Annuity comparison, the 25% tax-free lump sum calculator, Inheritance Tax planning tools (NRB, RNRB, gifts out of income), the Savings Interest and PSA calculator, and the council tax single-person discount (if living alone after a partner passes). The budget hub also tracks each year's State Pension triple-lock increase.
How are the audience hubs different from the calculator categories?
Calculator categories (Tax, Savings, Mortgages, etc.) organise tools by topic. Audience hubs (/for/) curate the same tools but filtered and contextualised for a specific person's situation — a freelancer's hub shows only the calculators relevant to freelancing, with sector-specific context about IR35, self-employment NI, and pension options. The hub pages also link to the most relevant guides and comparison articles for that audience, making it a starting point rather than just a list of tools.
Can professionals embed CalcHub calculators on their own website?
CalcHub provides an API for programmatic access to calculation results, suitable for accountancy firms, financial advisers and employer benefit platforms. The API documentation is at calchub.uk/api/. For embedding interactive calculators, individual calculator pages can be linked to directly. Commercial white-label or iframe embedding arrangements are available — contact CalcHub via the contact page. All calculator data is updated each tax year when HMRC publishes new rates and thresholds.
