How we calculate this
We compound your current pot and monthly contributions at your chosen annual growth rate, applied monthly, from your current age to your retirement age. At retirement, the projected pot is multiplied by a 4% sustainable withdrawal rate to estimate annual and monthly income. This is a simplified projection — it doesn't account for fees, inflation, tax, or investment volatility, so treat it as a rough guide rather than a guarantee.

The 25% tax-free lump sum
From age 55 (57 from 6 April 2028), you can usually take up to 25% of your pension pot as a tax-free lump sum, subject to an overall allowance. The remaining 75% is then taxed as income when you draw it. This calculator projects your whole pot and its income potential — it doesn't model the lump-sum split, since how much (if any) you take tax-free is your own choice.
Adding your State Pension
The pot above is only your workplace and personal pensions. Your State Pension is separate and paid on top, once you reach State Pension age — use the State Pension forecast calculator to add your own estimate to the numbers above and see your fuller retirement income picture. For the bigger question of what age you can actually stop working, see the UK retirement age calculator.
Frequently asked questions
How much do I need to retire in the UK?
It depends entirely on the lifestyle you want and what other income you'll have, including the State Pension. Use the calculator above to see what your own pot could realistically generate, and compare it against a recognised benchmark like the PLSA Retirement Living Standards, which describes what minimum, moderate, and comfortable retirements typically cost.
Is £100k a good pension pot?
A £100,000 pot, drawn down at a sustainable 4% a year, would generate roughly £4,000.00 a year (about £333.33 a month) on its own — before adding the State Pension. Whether that's "good" depends on your other income and expected spending; use the calculator above with your own numbers to see your real picture.
What growth rate should I assume?
A common range for a diversified pension portfolio is 3–7% a year before inflation, depending on how much risk you take. We default to 5% as a middle-of-the-road assumption — try 3% for a cautious estimate and 7% for an optimistic one, and compare the results.
Does this include the State Pension?
No — the pot projection above is your workplace and personal pensions only. The State Pension is added separately, worth up to £241.30/week if you have 35 qualifying National Insurance years. Use the State Pension forecast calculator to estimate your own amount and add it to your total retirement income.
What is pension drawdown?
Pension drawdown means keeping your pension pot invested after you start taking money from it, rather than buying an annuity, and withdrawing an income as you go. Because the pot stays invested, its value — and how long it lasts — depends on investment performance and how much you withdraw each year, which is why a sustainable withdrawal rate (this calculator uses 4%) matters.
