How much pension should I have on a £100,000 salary?

On a £100,000 salary, auto-enrolment puts £294/month (£3,522/year) into your pension — 5% from you and 3% from your employer on qualifying earnings. Starting at 30, this builds to a pot of around £309,594 by age 67. Whether that is enough depends on the retirement lifestyle you want. Most financial planners recommend a total contribution rate of 12–15% of salary.

Is 5% pension contribution enough on £100,000?

The auto-enrolment minimum of 5% employee contribution on £100,000 produces £183/month into your pension. Combined with 3% employer contribution, the total of £294/month is a start but is unlikely to provide a comfortable retirement. Increasing to 10–15% employee contribution significantly improves your projected outcome.

How much will my workplace pension be worth at retirement on £100,000?

On a £100,000 salary with the default 8% total contribution (5% employee + 3% employer), starting at age 30, your pension could grow to approximately £309,594 by age 67, assuming 5% nominal growth and 0.75% annual fees. Increasing your contribution rate or starting earlier significantly increases this figure.

What £100,000 means for your pension

£100,000 puts you within striking distance of the personal allowance taper. Between £100,000 and £125,140, the effective marginal tax rate is 60%: you pay 40% income tax and lose £1 of personal allowance for every £2 of income above £100,000. That lost allowance is then taxed at 40%, creating an additional 20% effective charge.

Pension contributions that bring your adjusted net income below £100,000 are the most tax-efficient contributions in the UK system. Every £1 contributed from within the 60% band costs you just 38p after combined tax relief and NI savings (with salary sacrifice). A single large contribution can restore thousands of pounds of personal allowance.

If your income fluctuates — through bonuses, share vestings, or overtime — consider using pension contributions proactively to keep adjusted income below £100,000 each year. You can check how much of the 60% trap affects you using our tax trap calculator, which models the interaction between pension contributions and the personal allowance taper.
