Calculate your auto-enrolment pension contributions
Employer Pension Costs
Auto-Enrolment Contribution Rates 2025/26
| Contribution | Minimum Rate | On Salary £35,000 |
|---|---|---|
| Employee | 5% | £1,438/year |
| Employer | 3% | £863/year |
| Total | 8% | £2,301/year |
Based on qualifying earnings (£6,240 - £50,270). Your employer may use different calculation methods.
Understanding Qualifying Earnings
For 2025/26, minimum pension contributions are calculated on "qualifying earnings":
- Lower threshold: £6,240 per year
- Upper threshold: £50,270 per year
- Only earnings within this band count for minimum contributions
Example Calculation
Qualifying Earnings: £35,000 - £6,240 = £28,760
Employee (5%): £28,760 × 5% = £1,438/year
Employer (3%): £28,760 × 3% = £863/year
Total: £2,301/year
The Power of Tax Relief
Pension contributions attract tax relief, making them very efficient:
| Tax Rate | You Pay | Tax Relief | Goes into Pension |
|---|---|---|---|
| Basic (20%) | £80 | £20 | £100 |
| Higher (40%) | £60* | £40 | £100 |
| Additional (45%) | £55* | £45 | £100 |
*Higher/additional rate taxpayers claim extra relief through Self Assessment
Should You Opt Out?
You can opt out of your workplace pension, but consider:
You Lose:
- Free employer contribution - typically 3-5% of salary
- Tax relief - 20-45% boost on your contribution
- Compound growth - decades of investment returns
Opting Out Might Make Sense If:
- You have high-interest debt to pay off first
- You're very close to retirement with another pension
- Your income is below the personal allowance anyway
Key Pension Rules for 2025/26 You Should Know
Understanding the latest pension regulations can help you make better decisions about your retirement savings. Here are the most important rules for the current tax year:
Annual Allowance: £60,000
You can contribute up to £60,000 per tax year to pensions and still receive tax relief (or 100% of your earnings, whichever is lower). This limit includes both your personal contributions and your employer's contributions. If you exceed this limit, you will face an Annual Allowance Charge on the excess, taxed at your marginal rate. However, you can carry forward unused allowance from the previous three tax years, which is particularly useful if you receive a large bonus or want to make a lump-sum contribution.
The Tapered Annual Allowance
High earners with "adjusted income" above £260,000 face a reduced Annual Allowance. For every £2 of income above this threshold, the allowance is reduced by £1, down to a minimum of £10,000. This taper affects those earning roughly above £260,000 including employer pension contributions. If you are a high earner, salary sacrifice arrangements can be especially beneficial, as they reduce your adjusted income while boosting pension savings.
Lifetime Allowance Abolished
From April 2024, the pension Lifetime Allowance was officially abolished. This means there is no longer a cap on the total amount you can build up in pension savings without incurring a tax charge. However, the tax-free lump sum you can take at retirement is now capped at £268,275 (25% of the old £1,073,100 Lifetime Allowance), unless you have transitional protection granting a higher amount.
State Pension and Workplace Pension Together
Your workplace pension sits alongside the State Pension, not instead of it. For 2025/26, the full new State Pension is £230.25 per week (approximately £11,500 per year). You need 35 qualifying years of National Insurance contributions to receive the full amount.
Most financial advisers recommend that your workplace pension should aim to fill the gap between the State Pension and your desired retirement income. The Pensions and Lifetime Savings Association suggests a "moderate" retirement lifestyle costs approximately £23,300 per year for a single person, meaning your workplace pension needs to provide at least £11,800 annually to supplement the State Pension.
Common Mistakes with Workplace Pensions
- Sticking with the minimum contribution: The 8% minimum (5% employee, 3% employer) is rarely enough for a comfortable retirement. If you start at age 22, aim for at least 12-15% total. Starting later means contributing even more.
- Not checking your pension fund choices: Most workplace pensions default to a "lifestyle" fund. Review your fund selection annually to ensure it matches your risk tolerance and retirement timeline.
- Losing track of old pensions: The average UK worker changes jobs 11 times during their career. Use the government's free Pension Tracing Service to locate any lost pension pots and consider consolidating them for easier management.
- Not nominating beneficiaries: Ensure your pension provider has up-to-date beneficiary details. Pension death benefits can be passed on tax-free if you die before 75.
Did You Know? Auto-Enrolment Earnings Thresholds
Auto-enrolment does not apply to all workers equally. To be automatically enrolled, you must be aged between 22 and State Pension age, earn at least £10,000 per year (the "earnings trigger"), and work in the UK. If you earn between £6,240 and £10,000, you are classified as a "non-eligible jobholder" and can opt in to your employer's pension scheme, though your employer is not required to contribute.
Workers earning below £6,240 are "entitled workers" who can join a pension scheme but receive no mandatory employer contribution. Importantly, these thresholds have remained frozen since 2020, meaning more part-time and lower-paid workers are now being automatically enrolled as wages rise. If you are close to the £10,000 threshold, check with your employer whether you can voluntarily opt in to secure their 3% contribution.
How Workplace Pension Calculator 2025/26 Works
This calculator applies the latest 2025/26 HMRC tax rates to estimate your tax position. The UK uses a progressive tax system where different portions of your income are taxed at different rates. Only income above the tax-free personal allowance is subject to tax, and each band applies only to the slice of income within that range.
Understanding your tax liability helps you make informed decisions about pension contributions, salary sacrifice, gift aid donations, and other tax-efficient strategies. This tool provides an estimate based on standard tax codes, though your actual position may differ if you have multiple income sources or special circumstances.
Key Information for 2025/26
The personal allowance is £12,570 (frozen until 2028). Basic rate: 20% on income from £12,571 to £50,270. Higher rate: 40% on income from £50,271 to £125,140. Additional rate: 45% on income above £125,140. The personal allowance reduces by £1 for every £2 earned above £100,000, creating an effective 60% rate between £100,000 and £125,140.
Example Calculation
On £42,000 annual income: £12,570 is tax-free, then £29,430 is taxed at 20% = £5,886 income tax. National Insurance adds £2,354 at 8% on earnings above £12,570. Total deductions: £8,240, leaving take-home pay of £33,760 per year or £2,813 per month.
