Pension Drawdown Rate Calculator
Sustainable drawdown rate from your pot.
Calculate annual and monthly income from your pension pot using a pension drawdown rate calculator. Adjust withdrawal rates to explore your options.
What this tool does
This calculator estimates the annual and monthly income you can draw from a pension pot at a chosen withdrawal rate. It multiplies your pension pot by your selected withdrawal rate to show the total income available each year, then breaks this into a monthly figure. The result illustrates how much you might access regularly from your savings. The withdrawal rate is the primary driver—even small changes significantly alter your income stream. A typical scenario might involve someone aged 55 with a pot of 250,000 exploring different rates to understand income options. Note that this calculation does not account for inflation, investment growth or losses, tax treatment, or any changes to your circumstances over time. It is provided for educational illustration only.

400,000 pot at 4% rate = 16,000 annual = 1,333/month. At 3% (safer long retirement): 12,000. At 5% (aggressive): 20,000. Rate choice drives income materially. Lower rates last longer but yield less; higher rates boost income but risk running out.
Quick example
With pension pot of 400,000 and withdrawal rate of 4%, the result is 16,000.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Pension Pot and Withdrawal Rate. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
What's happening under the hood
Pot × rate = annual income. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Turning the result into a plan
A projection is just a starting point. The real work is setting the monthly amount aside automatically so the saving happens before you can spend it. Most people who hit savings goals set up a standing order on payday; most who miss them rely on willpower at month-end.
What this doesn't capture
The calculation assumes a steady savings rate and a stable interest rate. Real saving journeys include emergencies, windfalls, and rate changes — especially in easy-access products. The figure is a direction of travel, not a guarantee.
Where to go next
This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the safe withdrawal rate calculator, the retirement pot size calculator, and the pension drawdown sustainability calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.
At a 4 withdrawal rate, your £400,000 pension pot generates 16,000.00 in annual income.
Inputs

Sources & Methodology
Methodology
This calculator computes your annual drawdown amount by multiplying your pension pot by your chosen withdrawal rate, expressed as a percentage. The result represents the amount you can withdraw each year based on that rate applied to your starting balance. The model assumes a constant withdrawal rate applied annually and does not account for investment returns, market volatility, inflation, fees, or changes in your pot value over time. It treats your pension pot as static and applies the same percentage uniformly, providing a straightforward calculation rather than a projection of sustainable income across multiple years or varying market conditions.
