Workplace Pension & Auto-Enrolment Calculator (2026/27)
Calculate employee contributions, employer statutory matches, tax relief, and qualifying earnings under UK auto-enrolment rules.
📊 Workplace Pension Contribution Summary
Under UK Automatic Enrolment law introduced by the Pensions Act 2008, all UK employers are legally required to automatically enrol eligible workers into a workplace pension scheme and make minimum employer financial contributions on their behalf.
The total statutory minimum workplace pension contribution is 8% of qualifying earnings, of which the employer must pay at least 3%, while the employee contributes the remaining 5% (which includes 1% tax relief from the government). Employers may choose to pay higher employer matches or calculate contributions on full gross salary rather than qualifying earnings.
⚙️ Rules & Thresholds
- Eligibility Criteria: Employers must automatically enrol workers who are aged 22 to State Pension age, earn over £10,000 per year, and ordinarily work in the UK.
- Qualifying Earnings Band (2026/27): Earnings between £6,240 (lower threshold) and £50,270 (upper limit). For a £35,000 salary, qualifying pensionable earnings equal £28,760 (£35,000 - £6,240).
- Statutory Minimum Contribution Split:
- Total Minimum: 8%
- Employer Minimum: 3%
- Employee Contribution: 5% (effective 4% net cost after 1% tax relief).
- Opt-Out Rights: Workers have a statutory 1-month window after auto-enrolment to opt out and receive a full refund of contributions. Every 3 years, employers must re-enrol opted-out staff.

📑 Common Pitfalls
- Opting Out of Free Employer Money: Opting out of a workplace pension means forfeiting the employer’s compulsory 3% contribution—effectively taking a pay cut.
- Confusing Qualifying Earnings with Full Salary: Some employers calculate pension percentages on full gross salary while others use qualifying earnings band (£6,240–£50,270); check your employment contract to verify your scheme’s basis.
- Net Pay vs Relief at Source Schemes: In ‘Net Pay’ schemes, low earners earning below the £12,570 Personal Allowance do not automatically receive government tax relief unless the scheme operates on a ‘Relief at Source’ basis.

Your accrued pension pot remains invested in your former employer's pension scheme. When starting a new job, you will be enrolled into your new employer's scheme.

Salary sacrifice is usually more tax-efficient than standard pension deductions because you agree to exchange part of your gross salary for employer pension contributions. This reduces your gross income for tax purposes, saving both Income Tax and National Insurance contributions for both worker and employer.
