Smart Tips

You may not reach your FIRE target by retirement

Your projected pot (in today's money) is £209,059, but your FIRE number is £750,000. Consider increasing contributions, reducing retirement expenses, or extending your working years.

Monthly income shortfall of £367

Your combined retirement income (pension drawdown + state pension) of £2,133/month falls short of your desired £2,500/month. Increasing contributions now can close this gap through compound growth.

You could take £108,746 tax-free

You can take 25% of your pension pot as a tax-free lump sum from age 55 (57 from 2028). The rest is taxed as income when you withdraw it.

Your pension gets tax relief from the government

Basic rate taxpayers get 20% tax relief automatically — a £100 contribution only costs you £80. Higher rate taxpayers can claim an additional 20% via self-assessment, making the effective cost just £60 per £100 contributed.

Frequently asked questions

How much do I need in my pension to retire comfortably in the UK?
A common rule of thumb is 25 times your desired annual income (the FIRE number based on the 4% withdrawal rule). For £30,000 per year you would need approximately £750,000. The actual amount depends on your state pension, other income, and planned retirement age.
What is the full UK state pension for 2026-27?
The full new State Pension for 2026-27 is £241.30 per week (£12,547.60 per year). You need 35 qualifying years of National Insurance contributions for the full amount, and at least 10 qualifying years to receive anything.
What is FIRE and how do I calculate my FIRE number?
FIRE (Financial Independence, Retire Early) means saving and investing aggressively to retire early. Your FIRE number is your desired annual income divided by your withdrawal rate — typically 4%. For £25,000 per year, your FIRE number is £625,000.
