Pension Projection Calculator (UK)
Use this Legal & General style pension calculator to estimate how much your pension could be worth by retirement, and what that may translate to as annual income.
This is an educational estimate, not financial advice. Actual returns, inflation, and pension outcomes will vary.
How this legal and general pension calculator helps
If you have a defined contribution pension, the big question is simple: Will I have enough? This calculator helps you estimate your potential pension value at retirement and converts that number into a rough annual income.
It is especially useful for a quick check if you are deciding whether to increase monthly contributions, retire later, or review your investment strategy.
What the calculator includes
- Current pension pot – your pension value today.
- Monthly contributions – what you and/or your employer add each month.
- Investment growth – assumed yearly return before charges.
- Annual charges – platform/fund fees that reduce net growth.
- Inflation adjustment – shows a value in today’s money.
- Withdrawal rate – estimates yearly retirement income.
Understanding the output
1) Projected pension pot
This is your estimated pension total at your selected retirement age, based on compounding growth and regular monthly contributions.
2) Inflation-adjusted value
Money in the future buys less than money today. The “today’s money” figure helps you compare future value in real terms.
3) Estimated annual income
The tool applies your selected withdrawal rate (for example 4%) to your projected pot. This gives a simple annual income estimate from drawdown-style planning.
Ways to improve your pension projection
- Increase contributions by even a small monthly amount.
- Use salary sacrifice if available to improve tax efficiency.
- Check your fees—lower costs can significantly help over decades.
- Review your risk level and fund choices regularly.
- Consider delaying retirement by 1–3 years for additional growth.
Important assumptions and limits
No pension calculator can predict markets. The results here are a model based on fixed assumptions. In reality, returns and inflation move year to year, tax rules can change, and your contribution pattern may vary.
For planning confidence, run multiple scenarios:
- Conservative case: lower growth, higher inflation.
- Base case: realistic middle assumptions.
- Optimistic case: stronger growth and stable costs.
Final thought
The best pension plan is one you can stick with consistently. Start with realistic numbers, review annually, and increase contributions when possible. Small improvements now can create a meaningful difference by retirement.
