Pension Basics for 20-Somethings

Why Pensions Matter Now

Every £100 saved at 22 could become about £2,100 by 67 (7% growth a year for 45 years, not guaranteed).

Starting Age£100/month = At 67
22£379,259
25£304,371
28£243,630
30£209,654

£100 at the end of each month, 7% a year compounded monthly, before charges and inflation.

Starting at 30 instead of 22 costs about £169,605 on these assumptions.

Auto-Enrolment Basics

DetailCurrent Rules

Minimum employer contribution3%

Who is enrolledYour employer must automatically enrol you in a workplace pension if you're a worker aged between 22 and State Pension age, earn at least £10,000 a year and usually work in the UK.

Student Loan Reality

FactImplication
Plan 5 (courses from August 2023): On a Plan 5 loan you repay 9% of your income over £25,000 a year, and anything left is written off 40 years after the April you were first due to repay.Low immediate impact; many won’t fully repay
Plan 2 (courses from 2012 to July 2023): 9% of income over £29,385, written off after 30 yearsLow immediate impact; many won’t fully repay
Doesn’t appear on your credit reportNot like normal debt
Interest up to RPI + 3%, currently capped at 6% (Plan 2)High but automatic

Usually not worth prioritising over other savings/investments.
