"I'd rather have the money now."

Fair enough. A pound you cannot touch until you are 57 genuinely is worth less than a pound in your pocket today. No argument there.

But your employer is offering to add free money on top of every pound you contribute, and the government chips in more through tax relief. The question is not whether the lock-in costs you. It does. The question is whether the free money more than makes up for it.

Plug in your numbers and find out.

For every £1 you put in

lands in your pension

But you can't touch it for 36 years, so that £1 is really worth

£0.76

Below £1 - at your discount rate, the lock-in outweighs the free money.

The offer on the table

You: £104 Employer: £63 Tax relief: £26
You sacrifice from your pay£104/mo
Your employer adds (free)+£63/mo
HMRC adds via tax relief (free)+£26/mo
Total hitting your pension£193/mo

Yes, it's locked away

You cannot touch this money for 36 years (until age 57). That is a real cost.

After discounting at 2.5% for the lock-in, the £193 going in each month is worth £79 in today's money. We do not apply expected growth here - you would get the same growth in an ISA, so it cancels out of the comparison.

You only sacrificed £104. Even after the lock-in penalty, you are -£25 better off every single month.

What you leave on the table by saying no

Per month

£89

Per year

£1,063

That is employer match and tax relief you simply do not get if you opt out. It is not deferred. It is gone.

The older you are, the less the lock-up costs you

The dashed line is the raw free money. The solid line shows what it is worth after discounting for the years you cannot access it. The gap narrows as you approach pension age.

Dashed: nominal free money. Solid: after discounting for years locked away. Gap = what the lock-up costs you.

Political risk is real

UK governments have repeatedly changed pension rules: the access age rose from 55 to 57, the lifetime allowance was scrapped and partially reinstated, and tax relief rules shift regularly. If you want to be conservative, raise the discount rate to price that uncertainty in. Even at a punitive discount, employer matching is almost always worth taking.

The bottom line

Yes, 36 years is a long time to wait. But for every £1 you put in, £0.76 ends up in your pension in today's money. Your employer and HMRC are handing you £89 per month of free money that vanishes the moment you opt out. Over a year, that is £1,063 you will never get back. Even the most aggressive discount rate cannot wipe out a return that generous. Take the match.
