What is the Pension Drawdown Tax Calculator?
The Pension Drawdown Tax Calculator helps you estimate how pension withdrawals may translate into taxable income, net income, and remaining pot value during retirement.
It is designed for people already retired or already drawing from a pension, especially those using flexi-access drawdown or UFPLS. You can include State Pension and other retirement income to see how withdrawals may interact with the wider tax picture.
How the Calculator Works?
Enter your age, pension pot, yearly withdrawal, State Pension, other taxable income, growth assumptions, and fees.
The calculator then estimates:
- Gross pension withdrawals
- Tax due
- Net income after tax
- How long the pot may last
- The difference between flexi-access drawdown and UFPLS on the same gross withdrawal
The projection is shown for the current tax year and then year by year through to your chosen plan age.
Step 1: Enter Your Retirement Position
Add your age, plan end age, current drawdown pot, annual withdrawal, and whether you are using flexi-access drawdown or UFPLS.
Step 2: Add Income and Assumptions
Include your State Pension, any partner State Pension, other taxable retirement income, expected real return, fees, and whether withdrawals should rise over time.
Step 3: Review Your Tax and Pot Projection
See your estimated net income, tax breakdown, FAD versus UFPLS comparison, and year-by-year projection showing how the pot may change over time.

How retirees might use the calculator
Pension withdrawals rarely sit on their own. State Pension, other taxable income, tax-free cash choices, and investment returns can all change the result. These examples show how different retirees might test their drawdown plan.
Margaret, taking steady drawdown
Margaret receives the full State Pension and wants to see how a regular pension withdrawal affects her taxable income and net income.
- Adds £12,548 State Pension
- Models 4% real growth and 0.6% fees
- Checks whether the pot lasts to age 92
Ravi, comparing FAD and UFPLS
Ravi has not yet started State Pension and wants to compare taking withdrawals through flexi-access drawdown versus UFPLS.
- Compares the same gross withdrawal both ways
- Checks the tax-free element under UFPLS
- Reviews his net income before State Pension starts
Linda, front-loading early retirement
Linda wants to take more income in the first few years of retirement for travel, then reduce withdrawals once spending settles.
- Uses the front-loaded withdrawal option
- Adds £5,000 other taxable income
- Checks the year-by-year tax and pot impact
What is the Pension Drawdown Tax Calculator?
The Pension Drawdown Tax Calculator is a UK retirement income tool that estimates tax on pension withdrawals, net income after tax, and how long a drawdown pot may last. It can include State Pension, other retirement income, flexi-access drawdown, UFPLS, growth assumptions, and fees.
What does the Pension Drawdown Tax Calculator do?
It estimates how gross pension withdrawals may translate into tax due, net income, and remaining pension pot value over time.
Who is this calculator for?
It is mainly for people already retired or already taking pension income. It is not designed for pre-retirement pension saving.
Does it include State Pension?
Yes. You can include State Pension and other taxable retirement income, which may affect the tax due on pension withdrawals.
What is flexi-access drawdown?
Flexi-access drawdown, often shortened to FAD, is where your pension remains invested and you take taxable withdrawals from it over time, usually after taking any pension commencement lump sum.
What is UFPLS?
UFPLS stands for Uncrystallised Funds Pension Lump Sum. With UFPLS, each withdrawal is usually treated as 25% tax-free and 75% taxable.
Why compare FAD and UFPLS?
Because the tax treatment can differ. UFPLS may include a tax-free element in each withdrawal, while FAD withdrawals may be fully taxable after any tax-free lump sum has already been taken.
Does the calculator model emergency tax?
It flags that a first pension withdrawal can be taxed using an emergency tax code, but it does not model PAYE Month 1 emergency tax in detail.
Does it include Scottish tax rates?
No. The calculator uses simplified UK assumptions and does not model Scottish income tax bands.
Does it include fees?
Yes. You can include a simple annual fee assumption, but it does not model detailed provider charges.
Does it include annuities or DB pensions?
No. It focuses on drawdown-style pension pots rather than annuities or defined benefit pensions.
How accurate is the pot projection?
It is an illustration based on steady assumptions. Real investment returns, withdrawals, fees, tax, and provider rules may differ.
Can I export the results?
Yes. The calculator includes CSV export functionality and may optionally use an email capture step depending on site settings.
