About this pension calculator

This free calculator projects how big your pension pot could be when you retire and what income it could provide. Enter your age, the age you want to retire, what you and your employer pay in, and it grows the pot month by month after charges, then turns it into a monthly income after income tax. It includes the new State Pension and works for most workplace and personal pensions.

What it shows

How it is calculated

Growth is added monthly at an equivalent rate to the yearly figure you enter, less charges, and contributions are paid in at the end of each month. Retirement income and tax are worked out in today's money using this year's tax bands, assuming they rise with inflation. It does not model final salary pensions, specific providers or funds, the lifetime allowance rules for very large pots, or carry forward. It is for guidance only and is not financial advice.
