What Is the UK Pension Calculator?

This tool projects the future value of your UK workplace or personal pension pot and estimates your potential retirement income. It models how your current savings, ongoing contributions, and tax relief will grow over time.

Who Should Use This Tool?

Anyone living and working in the UK who wants a clear view of their financial future. Whether you are relying purely on auto-enrolment or actively managing a SIPP, this tool helps clarify your long-term outlook.

Examples

Standard Auto-Enrolment

Example Input

£30,000 salary, 5% employee contribution, 3% employer contribution, 30 years to retirement.

Sample Output

Projects a modest final pension pot and highlights the potential shortfall in retirement income without additional saving.

Aggressive Pension Growth

Example Input

£50,000 salary, 10% employee contribution, 5% employer match, plus £20,000 current pot.

Sample Output

Estimates a robust retirement pot, demonstrating the powerful impact of compound growth and higher sustained contributions.

Common Use Cases

Use this calculator to see if your current contributions are enough to sustain your desired lifestyle. You can map out broad retirement goals with our global retirement calculator and see how your UK pension fits in.

Maximizing Your Forecast

Be conservative with your growth assumptions and account for inflation. Make sure you understand the difference between purchasing an annuity versus going into drawdown when evaluating your projected monthly retirement income.

Mistakes to Avoid

Don't forget to include the State Pension in your overall retirement planning if you have enough qualifying years. Also, opting out of workplace pensions means you miss out on free employer contributions—a concept central to the FIRE movement.

FAQ

What is pension auto-enrolment?

Auto-enrolment is a UK government initiative requiring employers to automatically enroll eligible workers into a workplace pension scheme and contribute to it.

How does pension tax relief work?

The government tops up your pension contributions by providing tax relief at your highest marginal income tax rate, meaning a £100 contribution costs a basic rate taxpayer only £80.

Can I take my pension as a lump sum?

Under current UK rules, you can usually take up to 25% of your pension pot as a tax-free lump sum from age 55 (rising to 57 in 2028).
