With a 5% pension contribution, your pension costs you £190/month in take home — but you're saving £6,000/year for retirement. Your employer likely adds another 3%+ on top. Don't opt out! Figures use 2025/26 rates and thresholds (frozen to 2028), so they also apply for 2026/27.
Understanding Your Pension on £120,000
On £120,000 you are in the heart of the 62% marginal zone (£100,000–£125,140), where the personal-allowance taper stacks on top of 40% tax and 2% NI. Every £100 sacrificed into your pension in this zone costs you only £38 of take-home. Escaping the taper entirely would take a £20,000 contribution (about 16.7% of salary) to bring taxable pay down to £100,000 — large, but it earns 62% effective relief on the whole slice.
Employer Contributions
At £120,000, employer pension contributions become particularly valuable because they are not subject to income tax or National Insurance. If your employer offers matching beyond the minimum 3%, always contribute enough to receive the maximum match. An employer contributing 8% adds £9,600/year — equivalent to a significant pay rise, and it does not touch your take-home at all.
Salary Sacrifice vs Net Pay
At £120,000, salary sacrifice is the standout option. In the £100,000–£125,140 taper zone each £100 of pension contribution costs only about £38 of take-home once the personal-allowance effect is counted, versus £58 for a higher-rate earner below £100,000. Net-pay and relief-at-source schemes still deliver the income-tax relief but not the 2% NI saving. For a detailed comparison, try our salary sacrifice calculator.
Building Your Retirement Pot
Saving 5% at £120,000 means £6,000 per year, but higher earners typically need to save a larger percentage to maintain their lifestyle in retirement — the State Pension replaces a much smaller share of a £120,000 salary than of an average one. Many financial planners recommend total contributions of 15-20% for those earning above £50,000. See the full breakdown of your take home pay at £120,000 salary after tax.

£20,000 — about 16.7% of salary — would bring taxable pay down to £100,000, where the personal-allowance taper stops. Everything sacrificed between £100,000 and £120,000 earns an effective 62% relief (40% tax, 2% NI and the taper effect combined).
Should I opt out of my workplace pension?
Almost never at this salary. Your marginal rate is 62%, so each £100 contributed costs only about £38 of take-home — and your employer adds its own contributions on top. Opting out gives up both.
