Pension Drawdown Calculator

Your drawdown strategy could be the most consequential financial decision of your retirement

Pension drawdown gives you flexibility, but it comes with real complexity. Tax on withdrawals, the effect of inflation on your purchasing power, and the risk of depleting your pot too early are all variables that need careful modelling — not guesswork.

This calculator uses current UK tax bands (2025–26) across all regions and gives you a transparent, detailed estimate so you can stress-test your assumptions before speaking to a professional.
