Understanding Pension Growth
Building a retirement pot is a marathon, not a sprint. It relies on consistent contributions and the mathematical power of compound interest. Here is how the math works.
Start with Your Current Pot
Your existing pension savings form the foundation. This amount will continue to grow exponentially over the years until you retire.
Add Regular Contributions
Each month, you and your employer contribute a percentage of your salary. The government then adds 20% basic rate tax relief on top of your personal contribution.
Apply Compound Growth
Your total pot is invested. Assuming an average annual growth rate, your money earns returns, and those returns subsequently earn their own returns year after year.
Project Retirement Income
At retirement, a common rule of thumb (the ‘4% rule’) suggests you can safely withdraw 4% of your total pot annually to provide a sustainable retirement income.

Pension Calculator FAQ
Answers to the most frequently asked questions about UK pension contributions, tax relief, and retirement planning.
A UK workplace pension is calculated by combining your personal contributions, your employer’s contributions, and government tax relief. This total amount is then invested, and compound interest grows the pot over time until your selected retirement age.
Under UK auto-enrolment rules, the minimum total contribution is 8% of qualifying earnings, with the employer required to pay at least 3% and the employee paying the remaining 5% (plus tax relief).
For every £80 you contribute from your net pay, the government adds £20 in basic rate (20%) tax relief, making it £100 in your pension. Higher and additional rate taxpayers can claim further relief through their Self Assessment tax return.
According to the Pensions and Lifetime Savings Association (PLSA), a ‘comfortable’ retirement for a single person requires an annual income of around £43,000, while a ‘moderate’ retirement requires around £31,000. The pot size needed depends on your retirement age and other income sources like the State Pension.
