What is the Retirement Withdrawal Strategy Calculator?
The Retirement Withdrawal Strategy Calculator helps you plan the optimal withdrawal sequence from your different retirement account types (ISAs, pensions, taxable accounts) to minimise tax and maximise efficiency. It shows you exactly how much to withdraw from each account type to meet your income needs while paying the least tax.
How the Calculator Works?
Enter your annual income needs and all your retirement accounts (ISAs, pensions, taxable accounts). The calculator determines the optimal withdrawal order to minimise tax. Typically, this means using ISAs first (tax-free), then pension tax-free lump sum (25%), then pension drawdown, then taxable accounts. The calculator shows the tax implications of each withdrawal and your net income after tax.
The tax-efficient strategy maximises your use of tax-free sources first, then uses taxable sources in a way that minimises your overall tax bill. This can significantly reduce your tax liability compared to withdrawing from accounts in a suboptimal order.
Step One: Enter Your Income Needs
Enter your annual income needs in retirement. This is the total amount you need after tax to cover your living expenses.
Step Two: Add Your Retirement Accounts
Add all your retirement accounts: ISAs (tax-free), pensions (with potential 25% tax-free lump sum), and taxable investment accounts. Enter the balance for each account.
Step Three: Choose Your Withdrawal Strategy
Select your withdrawal order strategy. Tax-efficient (recommended) uses ISAs first, then tax-free lump sum, then pension drawdown, then taxable accounts. You can also choose to use or skip the pension tax-free lump sum.

What is the Retirement Withdrawal Strategy Calculator?
It is a UK-specific tool that plans the optimal withdrawal sequence from different account types (ISAs, pensions, taxable accounts) to minimise tax and meet your income needs.
Why does withdrawal order matter?
Withdrawal order significantly impacts your tax bill. Using tax-free sources (ISAs) first means you pay no tax on those withdrawals. Using taxable sources in the wrong order can push you into higher tax bands unnecessarily.
What is the tax-efficient withdrawal order?
Typically: 1) ISAs (tax-free), 2) Pension tax-free lump sum (25%, tax-free), 3) Pension drawdown (taxable), 4) Taxable accounts (taxable, may also have CGT). This maximises tax-free withdrawals first.
Should I use the pension tax-free lump sum?
The 25% tax-free lump sum is a valuable tax-free source of income. Using it early in retirement (after ISAs) can reduce your overall tax bill. However, it reduces your pension pot for future drawdown, so consider your long-term needs.
How does it calculate tax?
Tax is calculated based on UK income tax bands (2026/2027 rates). The calculator adds up all taxable withdrawals and calculates tax on the total. It does not account for Capital Gains Tax on taxable accounts (simplified model).
What if my accounts can’t meet my income needs?
The calculator will show a shortfall warning indicating how much additional income you need. You may need to reduce your spending, work longer, or find additional income sources.
Can I add multiple accounts of the same type?
Yes. You can add multiple ISAs, pensions, and taxable accounts. The calculator aggregates balances by type and uses them in the withdrawal strategy.
Does it account for other income?
No. This calculator focuses on withdrawals from your retirement accounts. If you have other income (State Pension, rental income, etc.), you should account for that separately when planning your withdrawal strategy.
Can I see year-by-year projections?
Yes. The calculator shows a comprehensive year-by-year projection from your retirement age to your projection end age (default 90). This shows how your withdrawal strategy evolves over time, which pots are used in which years, and how remaining balances continue to grow with investment returns.
Does it account for investment growth on remaining balances?
Yes. The calculator applies your investment return assumption (default 5%) to remaining balances each year. This shows how funds continue to compound while not withdrawn, making projections more realistic.
Can I export the results?
Yes. Click the “Download CSV Export” button at the bottom to export your withdrawal strategy to CSV format. You’ll be asked for your email address before downloading.
