How to use our pension drawdown calculator

  1. 1Enter your current pension pot and age.
  2. 2Choose how much you want to withdraw each year.
  3. 3Adjust the investment growth and inflation assumptions to see how long your pension could last.

Your pension projection

The chart shows how your pension pot could change over time based on:

  • The value of your current pension pot
  • Your age and planned withdrawals
  • Whether you take 25% tax-free cash upfront
  • Your assumed investment growth
  • Inflation and how your withdrawals increase over time

Your result

The calculator shows how long your pension could potentially provide an income and the age at which your pot could run out based on your assumptions.

It is a simple projection designed to give you a starting point for thinking about your retirement income. The results depend on assumptions about investment growth and inflation, while actual investment returns will vary over time. The calculator also shows withdrawals before income tax, so your take-home income may be lower.

A financial adviser can help you assess whether your withdrawal rate is appropriate for your circumstances and consider other sources of retirement income, such as the State Pension or an annuity. They can use more detailed modelling, including different investment outcomes and sequence-of-returns risk, to help assess how sustainable your income could be.

Do you know how long your pension could last in drawdown?

Our free drawdown calculator helps you estimate how long your pension savings could last if you take an income from your pension while keeping the remaining money invested.

Enter your pension pot, your planned annual income, your age and other details. The calculator then estimates how your pension could change over time and how long your money could last.

This can help you answer an important question: will my pension provide the income I need throughout retirement?

The result is an illustration rather than a guarantee. Investment returns, inflation, the amount you withdraw and how long you live can all affect how long your pension lasts.

What is pension drawdown?

Pension drawdown allows you to take an income from your pension while leaving the remaining money invested. Unlike an annuity, which can provide a guaranteed income for life, drawdown gives you more flexibility over how much you take and when you take it. However, your pension remains exposed to investment performance, and taking too much income can cause your savings to run out sooner than expected.

This makes the level of income you withdraw an important part of your retirement planning.

How much can I withdraw from my pension?

There is no single withdrawal rate that is suitable for everyone. The amount you can afford to withdraw depends on the size of your pension, your other sources of income, your spending needs, your investments, and how long your retirement may last.

Taking a higher amount may give you more money to spend now, but it can also reduce the amount remaining in your pension and increase the risk of running out of money later.

A lower withdrawal rate may help your pension last longer, but may mean you have less income available immediately.

This is why it can be useful to model different withdrawal levels rather than choosing an amount based on a general rule.

What happens if I withdraw too much?

Taking too much from your pension can reduce the amount available later in retirement.

There is also a risk known as sequence of returns risk. If your investments fall in value early in retirement while you are also taking withdrawals, your pension may have less opportunity to recover.

For example, two people could have the same pension pot and take the same income, but experience very different outcomes depending on how their investments perform during retirement.

This is why your withdrawal strategy and investment approach can both be important when using pension drawdown.

What if my pension is not going to last?

If the calculator suggests that your pension may run out before your chosen age, there are several factors you could consider.

For example, you could explore:

  • reducing the income you take from your pension
  • delaying retirement or taking a lower income initially
  • using other savings or investments alongside your pension
  • considering other sources of retirement income, including the State Pension
  • reviewing your pension investments and charges
  • considering whether an annuity could provide some or all of your retirement income

The right approach depends on your circumstances. A calculator can highlight a potential problem, but it cannot determine which option is right for you.

Should I speak to a financial adviser about pension drawdown?

A drawdown calculator can be a useful starting point, but it cannot consider every aspect of your financial circumstances. Choosing how to take income from your pension involves decisions about investment risk, tax, income needs and how long your money may need to last.

A regulated financial adviser can help you assess your wider position and consider how pension drawdown fits alongside your other savings, investments and sources of income.

If you would like help deciding how to approach pension drawdown, you can use the Trusted Advisor adviser matching service to find a regulated financial adviser suited to your needs. Alternatively, email our team at hello@trusted-advisor.co.uk and we can help you understand the next steps.

Frequently asked questions

There is generally no fixed limit on how much you can withdraw through flexi-access drawdown. However, larger or more frequent withdrawals will reduce the amount remaining in your pension. Your withdrawal rate should take into account your expected retirement spending and how long you need the money to last. For UK retirees, most independent research suggests an initial withdrawal rate of 3.0-3.5% is prudent for a 30-year retirement, given UK equity returns, charges, and longer life expectancies. A higher rate may be sustainable if you have other income (DB pension, State Pension, rental) or are willing to flex spending in down years. For a UK retiree with 100% drawdown and no annuity floor, 4% is the upper end of what most independent UK research suggests is sustainable for a 30-year horizon.

You can usually take up to 25% of your pension tax-free, subject to the relevant allowances and rules. Further withdrawals are normally treated as taxable income and are added to your other taxable income for the year. The amount of tax you pay will depend on your overall income and tax position.

You can usually take part of your pension as a tax-free lump sum and leave the remainder invested through drawdown. This can give you access to a larger amount of money when you need it while keeping some funds available for future income. Your pension provider will explain which options are available under your specific plan.

Usually, you can change the amount you take from your pension as your circumstances change. You may also be able to stop withdrawals for a period and leave the remaining funds invested. The options available and any charges will depend on the terms of your pension scheme.

There is a risk that your pension could run out during your lifetime. This can happen if you withdraw money too quickly, investment performance is poor, or you need an income for longer than expected. Regularly reviewing your withdrawals and remaining pension can help you manage this risk.

Yes, you can generally continue working while taking money from your pension. Your earnings and pension withdrawals can both count towards your taxable income, which may affect the amount of tax you pay. Taking taxable pension income can also affect how much you can contribute to a defined contribution pension in the future.

Any money remaining in a defined contribution pension can generally be passed to your beneficiaries, subject to the pension scheme’s rules and the tax rules that apply at the time. The amount they receive and the tax treatment can depend on factors such as your age when you die. You should check your pension’s nominated beneficiary arrangements to help ensure the benefits are directed according to your wishes.
