UK Pension Projection Calculator (Unofficial)
This planning tool helps estimate your pension pot and possible retirement income. It is not an official GOV.UK calculator, but it uses common assumptions used in retirement planning.
For guidance only. Results are estimates and not financial advice.
Looking for the official pension calculator on GOV.UK?
If you searched for “pension calculator uk gov”, you’re probably trying to answer one simple question: “Will I have enough money in retirement?” The official UK government services are the best place to start for your State Pension forecast, while this page gives you an additional projection tool for personal and workplace pension planning.
Official UK government pension tools to use first
1) Check your State Pension forecast
Use the GOV.UK State Pension forecast service to see:
- Your estimated State Pension amount
- When you can claim it
- Whether you can improve it through National Insurance contributions
Official service: gov.uk/check-state-pension
2) Check your National Insurance record
Your NI record affects how much State Pension you may receive. You can review missing years and, in some cases, pay voluntary contributions.
Official service: gov.uk/check-national-insurance-record
3) Find lost pensions
If you’ve changed jobs a few times, old pension pots are easy to forget. The pension tracing service can help track down providers.

What this pension calculator does
This calculator estimates:
- Your projected pension pot at retirement (future £)
- An inflation-adjusted value in today’s money
- An estimated annual retirement income your pot could support
- Your total estimated income when State Pension is included
- Whether you are on track for your chosen target income
How to use it effectively
Use realistic assumptions
Small changes in growth rate, charges, and inflation can make a big difference over decades. Try optimistic, moderate, and cautious scenarios.
Review your contributions annually
Increasing monthly contributions after pay rises can dramatically improve your retirement projection. Even £50–£100 extra per month can have a meaningful long-term impact.
Don’t forget pension fees
Charges reduce net growth every year. A difference of 0.5%–1.0% in annual charges can materially change your final pension pot over 20+ years.
Example planning scenario
Suppose you are 35, plan to retire at 67, currently have £25,000 saved, and contribute £400 monthly. With net long-term growth after charges, your projected pension pot could grow substantially by retirement. From there, the calculator estimates annual income in today’s money and compares it with your target lifestyle budget.
If your projected income falls short, you can test solutions quickly:
- Increase monthly contributions
- Delay retirement by 1–3 years
- Lower expected retirement spending
- Reduce investment fees where possible
Important notes for UK retirement planning
- State Pension age may change in future.
- Tax rules and pension allowances can change.
- Defined benefit (final salary) pensions have different mechanics.
- Drawdown outcomes depend on market performance after retirement.
