About The Salary Calc

The Salary Calc is an independent, dedicated UK payroll and statutory taxation reference engine. We provide instant, transparent, and completely free take-home pay calculations for employees, contractors, job seekers, and financial planners across England, Scotland, Wales, and Northern Ireland.

Most online salary tools either hide their calculations behind aggressive lead capture, require sign-ups, or omit critical real-world deductions like Student Loan Plan 5, NHS unsocial hours enhancements, Scottish devolved tax tiers, or the 60% Personal Allowance taper trap. The Salary Calc models the full statutory reality down to the exact penny, showing you the exact formulas and band breakdowns behind every figure.

Every calculation on this site is rigorously calibrated against published statutory legislation from HM Revenue & Customs (HMRC), HM Treasury, and the Scottish Government (gov.scot). Our baseline models reflect the official 2026/27 tax year parameters:

• Income Tax: Standard £12,570 Personal Allowance, 20% Basic Rate (£12,571–£50,270), 40% Higher Rate (£50,271–£125,140), and 45% Additional Rate (over £125,140). Fully models the £100,000 allowance taper trap where personal allowance is reduced by £1 for every £2 of income.
• Devolved Scottish Rates: All six Scottish Income Tax bands (Starter 19%, Basic 20%, Intermediate 21%, Higher 42%, Advanced 45%, and Top 48%) based on official Scottish Budget enactments.
• National Insurance: Class 1 employee contributions at 8% on earnings between the Primary Threshold (£12,570/yr) and Upper Earnings Limit (£50,270/yr), and 2% thereafter.
• Student Loan Repayments: Complete statutory repayment thresholds for Plan 1 (£26,900), Plan 2 (£29,385), Plan 4 Scotland (£33,795), Plan 5 (£25,000), and Postgraduate Loans (£21,000).
• Update Cadence: Our engines are updated immediately upon the release of autumn budgets, spring fiscal statements, and annual uprating orders. An automated suite of over 640 unit tests verifies calculations daily against HMRC test payroll vectors.

Your income is confidential. Our calculations run 100% locally in your web browser via high-speed Web Workers and client-side JavaScript. Your salary, pension contributions, and tax details are never sent to, processed by, or stored on our servers. When you close or refresh your browser tab, your inputs are instantly wiped.

The Salary Calc operates independently of any financial institution or government body. While our models achieve near-payslip precision for standard PAYE environments, they provide general illustrative estimates and do not constitute formal tax, legal, or financial advice. For complex tax affairs, such as capital gains, foreign earnings, or corporate restructuring, you should consult an ICAEW- or ACCA-qualified accountant or regulated independent financial adviser (IFA).
