Pension drawdown calculator

Use our calculator to find out how long your pension could last when taking a regular retirement income.

Take retirement into your hands

Please remember, SIPPs are aimed at people happy to make their own investment decisions. Investment value can go up or down and you could get back less than you invest. You can normally only access the money from age 55 (57 from 2028). We recommend seeking advice from a suitably qualified financial advisor before making any decisions. Pension and tax rules depend on your circumstances and may change in future.

How to use the drawdown calculator

The drawdown calculator provides an illustration of how your pension income might look, based on things like retirement age and your estimated pot size.

Simply enter your details using the sliders and then adjust to see how a few changes could make a difference.

It is important to understand that the drawdown calculator only gives an estimate. Many factors are unknown and assumptions have been made. It is designed to show how making a few small changes can make a difference to your retirement. It does not provide a pension illustration.

We provide a pension illustration when you apply to open a SIPP account. We provide further illustrations annually and at other important times, such as when benefits are accessed. These are based on individual circumstances and the rules and assumptions set out by the Financial Conduct Authority.
