Pension Drawdown Calculator

This calculator estimates the sustainability of regular withdrawals from a defined contribution pension under drawdown.

It projects your pension pot over time, factoring in the annual amount you wish to withdraw, expected investment growth, annual charges, and inflation.

Tax calculations use current UK income tax bands and thresholds, with an option to model Scottish rates. The calculator also allows you to account for the 25% tax-free lump sum, reducing the amount left invested.

Each year, the model applies charges, adds investment growth, adjusts withdrawals and any other income for inflation (if selected), and then subtracts the desired after-tax withdrawal.

It tracks whether and when your pension pot would be depleted, and summarises the total tax and fees paid, total withdrawn, and final pot value.

This calculator does not provide personalised advice or guarantee that your pension will last for a specific period.

It cannot account for unpredictable investment returns, market shocks, changes in charges, or alterations to tax rules in future years.

It does not consider means-tested benefits, changes to your personal circumstances, or non-pension sources of income not entered in the ‘Other income’ field.

No allowance is made for inheritance tax, flexible withdrawal patterns, emergency withdrawals, or partial annuitisation.

The projections do not include every variable that could affect retirement income or outcomes and should not be relied upon as a substitute for regulated financial advice.

The calculator provides reasonable estimates for typical scenarios, using the information and assumptions you enter. Its tax logic reflects current UK legislation, and the growth, fee, and inflation calculations follow standard financial modelling practice.

However, actual investment returns, tax treatments, and charges may differ from those assumed. The results do not reflect market volatility, sequence of returns risk, or changes to pension or tax policy in future years.

The figures are accurate for broad planning and comparison purposes, but individual outcomes may vary, particularly if your circumstances are complex or market conditions are unusual.
