Pension drawdown calculator
Work out how long your defined contribution pension might last in drawdown by entering your planned withdrawals, growth rate, charges, and tax settings, with results showing if and when your pot could run out.
This pension drawdown calculator is designed to give you a clearer and more realistic picture than many standard tools, using a more comprehensive and flexible approach to modelling retirement income.
It allows you to explore different scenarios and see how outcomes can change over time, all without needing to enter any personal details, helping you plan and understand your options with more confidence.

Disclaimer: This calculator is for informational purposes only and does not constitute financial, investment, or tax advice. The results are based on assumptions you enter and current tax rules. Actual investment returns, charges, and personal tax circumstances can vary significantly.
You should not rely solely on this tool to make decisions about your retirement income. We strongly recommend seeking independent financial advice before taking any action relating to pension withdrawals or drawdown.
How to use this pension drawdown calculator
Begin by entering your pension pot size, your desired annual withdrawal, and the number of years you wish the withdrawals to last. You can expand the ‘Growth & Inflation’ section to set assumptions for annual investment growth, charges, inflation, and whether you want withdrawals to increase in line with inflation.
In the ‘Tax Options’ section, enter any other taxable income you expect to receive, and choose whether to take the 25% tax-free lump sum or apply Scottish tax rates.
As you adjust the inputs, results update automatically in the right-hand panel (or below on smaller screens), showing total withdrawals, tax, fees, and the projected value of your remaining pot over time. A chart displays how your pension pot may change year by year.
How this calculator works and the results explained
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.
Understanding the limitations
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.
