How It Works

This calculator projects the value of your pension pot at retirement based on your current contributions, employer contributions, investment growth and tax relief. It uses compound growth with monthly contributions to model how your pot grows over time.

UK pension contributions receive tax relief at your marginal rate. Basic-rate taxpayers get 20% relief automatically (a £100 contribution costs you £80). Higher-rate taxpayers can claim an additional 20% through Self Assessment. The annual allowance for 2025/26 is £60,000.

Auto-enrolment requires a minimum total contribution of 8% (5% employee + 3% employer). Many employers offer more generous matching schemes. The calculator lets you model different contribution levels and see the impact on your projected retirement income.

Example: Age 30, £40,000 salary, 5%+3% contributions, retiring at 67

  1. Monthly employee contribution: £166.67 (5%)
  2. Monthly employer contribution: £100.00 (3%)
  3. Tax relief (basic rate): £41.67/month
  4. Total monthly: £308.34
  5. Projected pot at 67 (5% growth): ~£390,000
  6. Potential annual drawdown (4% rule): ~£15,600

Frequently Asked Questions

How much should I save into my pension?
A common guideline is to halve the age you start saving and use that as a percentage of your salary. For example, if you start at 30, save at least 15% of your salary. The auto-enrolment minimum is 8% (5% employee + 3% employer).
What is the pension annual allowance for 2025/26?
The annual allowance for pension contributions in 2025/26 is £60,000. This includes both your contributions and your employer's. Tax relief is available on contributions up to this limit or your annual earnings, whichever is lower.
When can I access my pension?
You can usually access your defined contribution pension from age 55 (rising to 57 from April 2028). You can take up to 25% as a tax-free lump sum. The remainder is taxed as income when you withdraw it.
