Drewberry™ provide pensions, investment and insurance advice for Money to the Masses readers throughout the UK.

Our calculator provides a pension forecast for your retirement savings, and calculate how long your UK pension pot will last

Pension Pot Calculator

There are five major factors to consider when calculating how much your pension will be worth. These are:

  • Your age now – the earlier you start saving into a pension the better
  • Your chosen retirement age – the youngest age most people can access their pension is age 55, but not everyone can afford to retire this early
  • How much is already in your pension – any existing savings will provide a base for future growth
  • The monthly pension contributions you’ll be making – don’t forget employer contributions, if appropriate
  • The growth rate you’re expecting from your investments – our calculator offers a pension forecast based on your pot growing by 2%, 4% and 6% between now and retirement. With income drawdown your pension pot stays invested after you start taking income, so we’ve also modelled the same three growth rates for your pension fund post-retirement.

Pop all of the above details into our pension calculator to work out how much your pension could be worth at retirement and calculate how long your pension fund might last based on your desired retirement income.

Your Pension Contribution Results

Using our expertise we've modelled how much your pension could be worth at retirement given how much you're currently paying in and the age at which you've indicated you'd like to retire. Assuming your current contributions remain fixed between now and your retirement, we've put together three estimations of the size of your pension pot on that date based on low growth (2%), average growth (4%) and high growth (6%) scenarios.

How Long Will My Pension Last?

Now you know how much your pension fund may be worth, how long will it actually last in retirement? Answer the questions below and we'll do some clever calculations based on government projections of your life expectancy to work out the monthly income you could draw down from your pension.

Your pension pot at retirement

So far we've projected three pension pot sizes for you at retirement based on your contributions and three different growth rates.

At retirement, you're allowed to withdraw up to 25% of your pension tax-free.

You've chosen to take more than 25% of your pension pot upfront as a cash lump sum. Only the first 25% of your pension pot can be withdrawn this way tax-free. Anything above the initial 25% will be subject to income tax at your highest marginal rate.

Enter the income you would require in today's money. We will inflation proof your income in this calculation so it maintains the same purchasing power at retirement as it has today.


Your Income Drawdown Results

Given the income you'd like to receive, we've used our financial expertise to calculate how long your pension will last. With income drawdown your pension pot remains invested after you retire, so we've projected how long your pension will last based on your fund growing post-retirement by 2%, 4% or 6%.

You've saved hard into your pension pot your whole life, so it's essential you make the right choices at retirement and don't deplete your fund too soon. If you're considering income drawdown, it's very important you speak to an expert pension adviser. Please do not hesitate to call us on 02084327334.

This calculator is for illustrative purposes only. It is designed to provide an estimate of the size of your pension fund at retirement based on your current contributions and assumptions we've made about investment growth but is not a guarantee. Please note that this calculator does not constitute financial or other professional advice.

The growth rates indicated are only rough projections of how your fund could grow. As with any investment, your pension pot could rise as well as fall in line with market performance.

This calculator also provides an estimate of how long your pension could last in income drawdown but is meant only as a helpful projection, not financial advice. Income drawdown is just one option open to you for providing a retirement income and may not be right for everyone. You should consult a regulated financial adviser for individual retirement planning services or contact us for pensions advice on 02084327334 before making any decisions.


How much do I need to retire?

Many people wonder how much they need in their pensions to retire, but the answer isn’t simple because how much money you need for retirement depends on you as a person.

For instance, most pensioners today paid off their mortgages long before retirement. However, as people get mortgages later in life and with longer terms, future retirees could be repaying mortgages even after they’ve stopped working. That will need to be factored in to how much pension income you’ll need.
Gifts from your pension to children and grandchildren could seriously affect your income in the future

Are you planning on taking lots of holidays now you’ve retired? What about paying for hobbies now you’ve got more free time?

Other factors to consider are any children and grandchildren you might have. Will you have to support any dependants, perhaps paying for higher educational costs?

Some people might want to release their pensions to pay for a child’s wedding or a deposit on their first home, or start a savings account for new grandchildren. These costs in retirement will all need to be factored in to your pension calculations so you can decide how much you’ll need to live on.

Many of us simply aren’t saving enough into pensions to provide the comfortable retirement we deserve, so e might walk away from our pension calculator a bit shocked!

But that’s why we built our pension contribution calculator in the first place – to try and offer a realistic pension forecast given the size of your pension pot today and how much you’re planning to save. Forewarned with that figure you can seek expert advice, such as that offered by the team at Drewberry, to try and increase your pension if you’ve found it won’t last as long as you hoped.

Take 25% of Your Pension as Tax-Free cash from Age 55…

You’re entitled to take 25% of your pension as tax-free cash before you start drawing on it. You could use this to help fund costs such as those above, but the more you withdraw from your pension upfront the smaller the remaining pension pot will be. That means the monthly income you can take from your pension will also need to be lower.

There’s a pension lump sum calculation built into our pension calculator, so you can adjust the amount of money you want to withdraw from your pension at the start and see how it effects your overall income.

Also, don’t forget that if you take too much money too early, or your pension investments underperform, your pension could run out if you opt for income drawdown. What’s more, your income needs might rise as you get older and need to pay for care. Is the exorbitant cost of long-term care factored in to your pension calculations?

The pension contribution calculator is a start, but getting expert pensions advice can make all the difference

Need Pension Contribution Advice?

While the pension calculator offers you a good starting point when it comes to calculating how big your pension could be and how long it might last, it’s always better to get expert help and advice on your pension. At Drewberry we’re qualified to see you through the entire pensions advice process, from where to invest your pension savings to drawing on your same fund at retirement.

The pension calculator provides three different growth rates to model the size of your pension in the future, but much of this growth will depend on how your pension is invested.

I’ve helped many clients through their retirement planning journey, offering them regulated advice on their pension investments and retirement savings.

Matthew Brown was a very professional and welcoming advisor without pushing the 'hard sale'. He looked into various different options of cover and found the right insurance for my needs and to suit my budget. I've recommended Matt to friends whom I think he could also assist.

The value of pensions and investments and the income they produce can fall as well as rise. You may get back less than you invested. Tax treatment varies according to individual circumstances and is subject to change.
