## What is Calks.UK?

Calks.UK puts 331 free UK calculators in your pocket — and they all work offline, with no sign-up, no ads, and nothing leaving your phone.

Every calculation runs locally on your device, so your numbers stay private. Figures track the latest UK rates and thresholds for the 2026/27 tax year, and the app refreshes itself automatically when new calculators or rate changes go live — so you're never stuck on out-of-date numbers.

CALCULATE ANYTHING UK
• Tax & HMRC — Income Tax, National Insurance, take-home pay, Scottish Income Tax, dividends, Capital Gains, Corporation Tax, Self Assessment
• Pay & Salary — salary to hourly, pro-rata, overtime, payslip breakdown, minimum & living wage
• Mortgage & Property — repayments, affordability, Stamp Duty (SDLT), overpayments, remortgage
• Pensions & Retirement — contributions, tax relief, drawdown, State Pension
• Loans & Debt — personal loans, APR, credit-card payoff, car finance
• Business & Self-Employed — VAT, invoices, profit, IR35, contractor vs employee
• Savings & Investment — compound interest, ISA, savings goals
• Benefits & Welfare — Universal Credit, Child Benefit, statutory pay
• Motoring — fuel cost, mileage, EV charging, road tax (VED)
• Health & Fitness — BMI, BMR, calories, body fat

WHY CALKS.UK
• Works 100% offline — use it on the train, abroad, anywhere

• No ads, no account, no nonsense
• Always current — rates update automatically, over the air
• Clear, step-by-step results with plain-English explanations and FAQs

Whether you're an employee checking your take-home pay, a freelancer working out VAT and IR35, a homebuyer estimating Stamp Duty, a saver planning ahead, or you just need a quick, accurate answer — Calks.UK has a calculator for it.

Free. Offline. Private. Try it today.

Calculations are estimates for general guidance and are not financial advice. For decisions, check gov.uk or a qualified adviser.
