About AfterTaxCalculator
We believe everyone deserves complete transparency when it comes to their finances. Our mission is to provide the most accurate, private, and intuitive UK tax calculations on the web.
Our Mission
Understanding your payslip shouldn't require an accounting degree. We built AfterTaxCalculator because we were frustrated by the overly complex and confusing tax calculators currently available on the market.
Our goal is simple: to help UK employees, freelancers, and job seekers understand exactly where their hard-earned money goes—instantly, accurately, and without compromising personal data.
Our Core Values
Lightning Fast & Accurate
Calculations are performed instantly as you type. We continuously update our algorithms to reflect the latest UK tax bands, National Insurance rates, and student loan thresholds for the 2026/27 tax year.
Privacy First
Your financial data is incredibly sensitive. That's why AfterTaxCalculator runs entirely in your browser. We do not track, store, or transmit your salary information to any servers.
Free to Use
Financial literacy should be accessible to all. Our core calculator is and always will be completely free to use without any hidden paywalls or premium subscriptions.
Open & Modern Tech
Built with modern web technologies including Next.js, React, and Tailwind CSS. The interface is designed to be responsive, accessible, and beautiful across all your devices.
