Should I opt out of my workplace pension?
Almost never. Opting out means turning down your employer's 3%+ contribution — free money. The combined 8% (5% you + 3% employer) on £30,000 = £1,860/year, of which only £1,200 comes from you (with tax relief). Even on a tight budget, the long-term benefit is huge.
Full answer
UK workplace pension opt-out analysis. Under auto-enrolment, the minimum is 5% from you (incl. tax relief) + 3% employer. On £30,000 qualifying earnings (£23,760 between £6,240–£50,270): your gross contribution £1,188, after 20% tax relief net cost £950; employer adds £712. Total annual £1,900 into your pension for £950 out of your post-tax pocket — 100% match before investment growth. Over 40 years at 5% real return, £950/year compounds to ~£114,000 in today's money. Reasons people consider opting out: (1) urgent debt at 20%+ interest (credit cards, payday loans) — possibly justified short-term; (2) about to retire (under 50: definitely stay in; over 55, model individually); (3) accessing benefits (Universal Credit income definition affected — but generally opt back in once stable). Reasons to definitely stay in: every salary multiple counts; tax relief; salary sacrifice can save NI on top. You can opt back in once per 12 months and your employer must accept.
