If you've ever squinted at your payslip trying to work out why the pension deduction is the number it is, you're not alone. Auto-enrolment contribution rates look simple on the surface — 8% of qualifying earnings — but the detail of how that 8% is split, and what it's actually calculated on, catches a lot of people out. This page sets out exactly how the current minimum rates work, what "qualifying earnings" really means in pounds and pence, and how your own scheme might differ from the legal minimum.
The current minimum contribution rate
Since April 2019, the legal minimum total contribution under auto-enrolment has been 8% of qualifying earnings. Of that 8%, at least 3% must come from your employer, meaning your own contribution (including tax relief) makes up the remaining 5%. These are minimums, not targets — many employers contribute more, either because they want to be a more attractive employer or because their scheme design (for example, a "matching" scheme that increases employer contributions if you increase yours) works that way.
What counts as "qualifying earnings"
This is the part that trips people up most. Contributions aren't calculated on your entire salary — they're calculated on a band of earnings between a lower and upper threshold, called qualifying earnings. For 2026/27, that band runs from £6,240 to £50,270 a year. Anything you earn below £6,240 isn't included in the calculation at all, and anything above £50,270 isn't included either — the percentage only applies to the slice in between. Qualifying earnings also include more than just basic salary: overtime, bonuses, commission, and statutory sick or maternity pay all generally count, which is one reason contribution amounts can genuinely fluctuate month to month even for someone on an otherwise fixed salary.
Take Priya, who earns £28,000 a year. Her qualifying earnings are £28,000 minus £6,240, which comes to £21,760. Her total 8% contribution is therefore 8% of £21,760 — around £1,741 a year, or roughly £145 a month — not 8% of her full £28,000 salary (which would be £2,240). This is why two people on similar-sounding salaries can see quite different pension deductions if their employer calculates contributions differently.
Qualifying earnings vs pensionable pay schemes
Not every scheme uses qualifying earnings as its basis. Some employers instead calculate contributions on "pensionable pay," which might mean your whole salary or your basic salary excluding bonuses. Schemes using this "certification" approach are allowed to set slightly different percentages (for example 7% of pensionable pay, if pensionable pay is close enough to total pay) provided the overall contribution meets an equivalent standard set by the regulator. In practice, a pensionable-pay scheme calculated on full salary is usually more generous than the qualifying earnings minimum, since there's no lower threshold stripped out first. It's always worth checking your scheme booklet or asking payroll which basis your employer uses.
There are, broadly, three certification approaches an employer can use instead of the standard qualifying earnings basis: a minimum of 9% of pensionable pay with at least 4% from the employer, a minimum of 8% of pensionable pay (at least 3% employer) provided pensionable pay is at least 85% of total pay for the whole workforce, or a minimum of 7% of total pay (at least 3% employer) if all earnings are pensionable from the first pound. Each route is designed to achieve a broadly equivalent, or better, outcome than the qualifying earnings method, so don't assume a different percentage automatically means a worse deal — check what it's actually a percentage of.
How rates have changed over time
-
1
2012-2018: contributions phased in gradually, starting at just 2% total (1% employer, 1% employee) for the earliest staging employers.
-
2
April 2018: minimum total rose to 5% (2% employer, 3% employee).
-
3
April 2019: minimum total rose to the current 8% (3% employer, 5% employee including tax relief), where it has stayed since.
-

Qualifying earnings thresholds (£6,240 lower limit, £50,270 upper limit) are reviewed each tax year, and the upper limit is currently aligned with the income tax higher-rate threshold, though the two have been frozen together in several recent years.
Boosting your contributions above the minimum
Because 8% is a floor, not a ceiling, many savers choose to contribute more than the statutory minimum, particularly once they've cleared other financial priorities like an emergency fund or high-interest debt. A very tax-efficient way to do this is through salary sacrifice, where you give up part of your salary in exchange for an equivalent (or enhanced) employer pension contribution, saving on National Insurance in the process. See our dedicated guide on how salary sacrifice works for the detail on how this can increase your effective contribution at no extra net cost.
Some employers also operate "matching" schemes, where they'll increase their own contribution if you increase yours, up to a specified cap — for example matching your contribution pound for pound up to 6% each. If your employer offers this and you can afford to increase your own contribution, it's usually one of the most efficient ways to boost retirement saving available, since the extra employer match is, in effect, free money on top of what you're already choosing to put in.
Whatever you and your employer contribute counts towards your annual allowance for tax relief purposes — see how the annual allowance works if you're a higher earner or considering large additional contributions.
Checking your own contribution rate
The clearest way to check what you and your employer are actually paying is your annual pension statement, which every scheme must issue, or your pension provider's online portal, which usually shows contribution history month by month. Your payslip will show your own deduction, but it won't always show the employer contribution alongside it, so don't assume the number on your payslip is the whole picture — always add the employer's share to get the true total going into your pot each month.
If you're unsure whether your employer is meeting even the legal minimum, The Pensions Regulator is the enforcement body for auto-enrolment compliance, and persistent underpayment is something they actively investigate. Most shortfalls, though, are innocent payroll errors rather than deliberate underpayment, and are usually resolved quickly once flagged to HR or payroll.
Why contribution rates matter more than they seem
A difference of even one or two percentage points in contribution rate can have an outsized effect on your eventual pension pot, purely because of how long the money is typically invested for. Someone contributing an extra 2% of qualifying earnings from age 25 rather than starting at the statutory minimum could, depending on investment returns, end up with a materially larger pot by retirement — often tens of thousands of pounds more — simply because that extra saving compounds for decades. This is why it's worth periodically reviewing your contribution rate rather than assuming the statutory minimum is automatically "enough," particularly if you receive a pay rise and haven't adjusted your pension contribution to match.
In short, the 8% minimum is a legal floor designed to get everyone saving something, not a considered recommendation of what you personally need for a comfortable retirement. Many independent guidance bodies suggest a combined contribution rate closer to 12-15% of full salary is a more realistic target for a comfortable retirement income, which is worth bearing in mind if you're in a position to contribute more than the statutory minimum.
