Pension Calculator

Find out what your retirement income could be

How much do I need to retire?

Our Pension Calculator uses your current age and pension savings to give you an idea of what your retirement income could look like. It can help you answer questions like ‘What will my retirement look like?, ‘How much do I need to retire?’ and ‘When can I retire?’.

Once you have an idea of whether or not you’re saving enough to meet your pension goals at retirement, talk to a Financial Adviser who can help you achieve the kind of retirement you want.

Using the simple sliders, you can estimate how much you will have in your pension pot when you reach your retirement age and the income this can provide.

You’re on track to have at retirement.

If you take per year, this will last until age .

This calculation assumes a mid-level growth rate of 5% per year, inflation of 2% per year and pension fees of 0.7%. Growth, inflation and ongoing charges will vary. The aim of this pension calculator is to give you an idea of the level of income your current pension benefits could provide you with and/or how much you might need to save into a pension to get the income you’re aiming for in retirement. It’s not personal advice or suitable for calculating the potential income from a defined benefit scheme, e.g. a final salary scheme. If you’re not sure what’s best for your situation, you should seek personal advice.

The value of investments and any income from them can fall and you may get back less than you invested.

Considerations when using our pension calculator

This tool is not a recommendation or financial advice. Our pension calculator uses growth rate estimates – so the figures here are not a guarantee, but a guide. We would recommend speaking to one of our Financial Advisers to plan for your retirement.

Understanding your Pension calculator

  • What is your planned retirement age?

    What is your planned retirement age?

    If you are considering when you would like to retire, a good place to start would be to find out how much your current schemes will be worth and what you can expect for your State Pension.

    Whether or not you’re entitled to the Full State Pension depends on your National Insurance record. You could receive up to £230.25 a week or £11,973.00 a year (correct for 2025/26 tax year). Find out when you can expect to receive your State Pension and whether you will receive the full amount at Gov.uk.

    How to gather information about your pensions:

    • If this is a Defined Benefit pension this will be based on your current (or final salary when leaving) and how long you have been a member of the scheme. You will need to contact the Scheme to receive a statement if you do not have these sent to you automatically.
    • For Defined Contribution pension, where the value is based on the amount you and your employer has contributed, and any investment growth, you can ask the scheme for an annual statement (if you do not receive these already).
    • You may need to track down and find forgotten pensions. There are companies that offer to help with this, but you can track them down yourself with the Government’s scheme finder.
  • Do you wish to take your tax-free cash at retirement?

    Do you wish to take your tax-free cash at retirement?

    Thanks to Pension Freedoms rules, you can take 25% of your pension tax-free at age 55 (correct at current tax year 2025/26). This can help you pay off your mortgage, make home improvements, and help you get ready for the future. The most important thing to bear in mind when accessing

    your pensions is that while 25% of your total fund can be withdrawn tax-free, if benefits exceed the LSDBA it will be subject to income tax. If this is the case then you are likely to face 20%, 40% or even 45% tax on those withdrawals, eroding years of pension savings in a moment, which can’t be reversed. Learn more about pension tax advice here.

    You have the power to choose how you use your pension pot. It’s up to you to manage your spending and ensure that you have enough income to last for the whole of your retirement. There are four main options for how you can use your pension pot, which we will outline in our Pension Freedoms brochure; purchase an Annuity, take your tax-free lump sum, take smaller lump sums, or use Flexi-access drawdown.

    Even if you’re already retired and drawing on your pension benefits, you can still contribute to your pension fund. This is particularly useful for those taking a phased-approach to retirement, and are still contributing to a workplace pension.
