Frequently Asked Questions

How much should I be paying into my pension?

Under auto-enrolment, the UK minimum is 8% of qualifying earnings: at least 5% from you and 3% from your employer. However, to retire comfortably, most financial planners recommend 15% of your salary or more. The earlier you start, the less you need to contribute each month.

What is the 4% drawdown rule?

The 4% rule is a widely used retirement income guideline suggesting you can withdraw 4% of your pension pot in the first year of retirement, then adjust for inflation each year, with a high probability of not running out of money over a 30-year retirement. It is a guide, not a guarantee.

What growth rate should I use?

A 5% annual growth rate (before inflation) is a common moderate assumption for a balanced pension fund. Conservative investors might use 3-4%. Growth-oriented investors might use 6-7%. Real returns (after inflation) are typically 2-3% lower than nominal returns.

Does this include the state pension?

No. This calculator projects your workplace or personal pension pot only. The full UK new State Pension for 2024/25 is £221.20 per week (approximately £11,502/year) for those with 35+ qualifying National Insurance years. Add this to your projected income for a fuller picture.
