Pension Pot Calculator UK

How this pension pot projection works

The calculator starts with the pension value entered, adds your monthly payment and the employer payment, then applies investment growth and charges each month. Contributions are assumed to be paid at the end of each month. The result is a defined contribution pot estimate, not a guaranteed retirement income.

What the results show

The projected pot is the estimated future cash value. The value in today’s money discounts that figure using the inflation rate you enter, making long projections easier to interpret. Total contributions include the opening pot plus all personal and employer payments. Investment gain after charges is the amount left above those contributions.

Worked example

Suppose a pension already contains £25,000. You add £300 per month and an employer adds £150 per month for 25 years. With a 5% annual return, 0.75% annual charges and 2.5% inflation, the calculator compounds the balance monthly and gives both a future value and an inflation-adjusted value.

Returns and pension charges matter

MoneyHelper explains that investment growth can have a large effect on a defined contribution pension, while providers normally deduct fees from the pot. Its official pension calculator guidance can help with broader retirement-income planning. This page uses the return and charge assumptions you choose rather than predicting actual market performance.

Contributions and tax relief

Enter amounts that actually reach the pension. Depending on the scheme, tax relief may be added automatically or contributions may be deducted before Income Tax. Employer payments and contribution definitions also vary, so check a payslip or pension statement instead of assuming the legal minimum applies to the whole salary.

Pension pot calculator UK: how much could you have at retirement?

This free pension pot calculator projects the value of a defined contribution pension over the years you have left to save. Enter the balance you have today, the amount you and your employer contribute each month, and assumptions for investment growth, pension charges and inflation. It estimates a future pension pot and its value in today’s money. It is a projection, not a guaranteed return or a valuation of a defined benefit (final salary) pension.

How much is my pension pot worth today?

To find the current value of your pension pot, check the latest statement or online account from your pension provider. If you have several workplace or personal pensions, check each separately and add their current values only if you want a combined projection. An old statement may not reflect recent contributions, charges or investment movements. This calculator cannot look up pension accounts or trace lost pensions; it uses the current pot value that you enter.

How to calculate pension pot growth

For a pension pot growth calculator comparison, try the same contributions and saving period with different annual return assumptions, such as 3%, 5% and 7%. Then increase the annual charges assumption to see how fees may reduce the projected balance. Investment returns are not smooth in real life: markets can fall, and the calculator uses a simplified regular-growth model rather than simulating yearly volatility. Higher assumed growth does not mean higher growth is likely or guaranteed.

Pension pot examples: £25,000 today with monthly contributions

As an example, start with £25,000 in pension savings, contribute £300 a month and add £150 a month from your employer for 25 years. Use 5% assumed annual growth, 0.75% annual charges and 2.5% inflation. The calculator then separates the projected future cash value from its estimated buying power in today’s money. Change one input at a time to see whether contributions, time, charges or growth assumptions have the largest effect. These are illustrative inputs, not investment forecasts.

How much should I pay into my pension each month?

The amount you need to contribute depends on your existing pension savings, retirement age, other income and spending plans. Employer contributions and applicable tax relief can make a substantial difference. Enter contributions that actually reach the pension pot to avoid counting tax relief twice. Check workplace pension rules, annual allowances and any employer matching arrangement before increasing payments. This tool does not calculate tax relief eligibility or automatically apply pension contribution limits.

Pension pot at 55, 60, 65 or 67

To estimate your pension pot at a chosen retirement age, set the number of years until that age. For example, if you are 40 and plan to retire at 65, use 25 years. Comparing 60 with 67 can show the effect of seven extra years of contributions and potential investment growth. Your chosen retirement age is a planning assumption; it does not determine when you can legally access a particular pension or when you receive the UK State Pension.

What can you do with your pension pot at retirement?

Once you are eligible to access a defined contribution pension, options may include leaving it invested, taking permitted lump sums, using pension drawdown or buying an annuity. The best choice depends on tax, income needs and risk. A projected pension pot is not the same as guaranteed retirement income.
