Our Mission
Quick Calculator UK was created with a simple goal: to provide the best free online calculators for people living and working in the United Kingdom. We believe that everyone should have access to accurate, easy-to-use tools for the calculations that matter in everyday life — from working out your take-home pay to estimating how much paint you need for a room.
What We Offer
We currently offer 14 free calculators across four main categories:
- DIY & Building: Paint, plaster, and wallpaper calculators with UK-specific coverage rates and material sizes.
- Employment & Salary: Salary, minimum wage, overtime, holiday entitlement, and redundancy pay calculators using the latest HMRC and government rates.
- Tax & VAT: Income tax, VAT, and self-assessment calculators for the 2025/26 tax year.
- Everyday: BMI, age, and percentage calculators for daily use.
Our Commitment to Accuracy
We take accuracy seriously. All tax and employment calculators are updated each April when new HMRC rates come into effect. Our DIY calculators use industry-standard coverage rates from leading UK manufacturers. Every calculator is tested against manual calculations and cross-referenced with official sources.
That said, our calculators provide estimates only. Individual circumstances vary, and we always recommend consulting a qualified professional for important financial decisions.
Privacy and Data
All calculations happen locally in your web browser. We do not collect, store, or transmit any numbers you enter into our calculators. The only data we collect is standard anonymous analytics to understand which tools are most popular, so we can focus on improving them. Read our full privacy policy for details.
Advertising
Quick Calculator UK is supported by advertising through Google AdSense. This allows us to keep all calculators completely free to use. We strive to keep advertising unobtrusive and clearly separated from calculator content.
