About Clear Calculators

Clear Calculators is an independent UK website published by Vyseroy. It helps people check take-home pay, tax and National Insurance estimates, shopping comparisons and selling costs. The tools are free to use without an account.

Who runs the site

The site is maintained by Vyseroy as a sole independent publisher. It is not affiliated with HMRC, GOV.UK, Royal Mail, eBay, an employer or a financial adviser. The site is not currently showing adverts, and advertising will not determine the results, source notes or order of tools.

For questions or corrections, email feedback@clearcalculators.co.uk or use the feedback form. Include the tool, options and result you want checked. Please do not send personal financial documents.

What you can check

The main tool is the UK Pay Calculator, which separates Income Tax, National Insurance, pension and student-loan deductions. Related pages cover payslips, overtime, bonuses, salary sacrifice and holiday pay. Shopping and seller tools sit alongside those pay checks for household money decisions.

Each tool states its assumptions. Estimates cannot account for every contract, tax code, marketplace fee or personal circumstance; check the relevant official source before relying on a result for a decision.

Recent corrections and updates

On 6 September 2026, we added billing-month lengths and clearer input warnings to Broadband Usage, made Price Increase calculations shareable, and added worked payroll and creator-income checks. The review record describes what was tested and what was outside its scope.

On 1 September 2026, we corrected the eBay promotion-fee basis, the display of percentage changes from a zero price, and calendar bank-holiday counts. On 5 September, we added sourced parcel limits and a complete sponsorship quote example.

The methodology page explains the calculations and review approach. Checks include ordinary inputs, boundary cases and warnings. Coverage varies by tool; a successful test is not a guarantee that every possible scenario has been covered.

Privacy and accessibility

Calculator inputs are processed in the browser where possible, with some settings saved on your device. Our privacy policy explains local storage, advertising and feedback messages.

The site supports keyboard navigation, labelled controls, small screens and light and dark themes. If something is difficult to use, tell us which page and what happened.
