  • What you have now£20,000
  • You put in£76,111
  • Your employer adds£45,667
  • Investment growth£303,611

What this means

About 68% of it is investment growth, not money you put in. The earlier you start, the longer each contribution has to grow.

Your employer adds £45,667 over the years: extra pay you only get by saving yourself.

Prices will rise, so £445,389 in 37 years buys about what £178,631 buys today.

Assumptions in this estimate
  • Auto-enrolment minimums are 5% from you (including tax relief) and 3% from your employer, on earnings between £6,240 and £50,270. These limits stay at today’s levels.
  • Tax relief is at your top rate of Income Tax, and at least the 20% basic rate, even if you earn too little to pay tax. With relief at source, basic-rate relief is added automatically and higher-rate taxpayers claim the rest through Self Assessment.
  • Growth is after fees. Your pay rises by 3% a year, and “in today’s money” takes off 2.5% inflation a year.
  • You can usually take 25% tax-free, up to £268,275 in total. The minimum age to take a pension rises from 55 to 57 in April 2028.
  • Salary sacrifice also saves National Insurance, which isn’t included here.

How the calculator works

  1. Contributions: a share of your pay from you (including tax relief) and from your employer, worked out on qualifying earnings or your whole salary.
  2. Tax relief: what your contribution really costs you, after relief at your top rate.
  3. Growth: your pot grows at the rate you choose, after fees, and your pay rises each year.

What paying more adds

Starting at 30 on £35,000 with £20,000 saved:
