What this estimator works out
This estimator converts a pension pot into an indicative annual income at a withdrawal rate you choose, then adds any other income you expect. It returns an annual and monthly figure before tax.
It answers the question a pot value cannot: what does £300,000 actually mean in terms of money to live on. The answer is usually lower than people expect, which is precisely why the calculation is worth doing early.

Before you rely on the figure
- Use the current value of all your pots combined, including any from previous employers.
- Choose the withdrawal rate deliberately. 4% is a common reference point; 3% is more cautious and appropriate for a long retirement.
- Include the State Pension in other income, using your forecast from GOV.UK rather than an assumption.
- Remember the result is before tax. Pension income above your Personal Allowance is taxable.
Drawing an income from an invested pot leaves you exposed to markets and to living longer than planned, but keeps the capital yours. An annuity converts the pot into a guaranteed income for life, removing both risks but giving up the capital. Many people now use a combination, covering essential spending with guaranteed income and discretionary spending from drawdown.
How this calculator works
One multiplication and one addition:
Income from pot = pot × withdrawal rate
Total annual income = income from pot + other income
Monthly = total ÷ 12This is a static calculation: it does not model the pot running down, investment returns during retirement, or income rising with inflation. It shows what the pot would support at a chosen rate in the first year.
The 25% tax-free lump sum most people can take is not modelled either. Taking it reduces the pot available for income, which is a trade worth calculating rather than assuming.
Worked example: a £300,000 pot
Using the default figures — a £300,000 pot, a 4% withdrawal rate and £12,000 of other income:
- Income from the pot: £300,000 × 4% = £12,000 a year
- Total with other income: £24,000 a year
- Monthly before tax: £2,000
A £300,000 pot sounds substantial and produces £1,000 a month. Drop the withdrawal rate to 3% for a longer retirement and it produces £750. This is the calculation that most changes people's plans, and it is worth running a decade or more before you need it, while contributions can still make a difference.
Common mistakes
- Assuming the pot value is spendable income. A pot supports an income; it is not one.
- Using 4% without thinking about how long retirement might be. A retirement starting at 60 may run 35 years.
- Forgetting tax. Only the first 25% is normally tax-free; the rest is taxed as income.
- Overlooking the effect of taking the lump sum. It reduces the pot generating income.
- Ignoring inflation. An income that does not rise loses purchasing power every year of a long retirement.
Frequently asked questions
Is 4% a safe withdrawal rate?
It is a widely used reference point rather than a guarantee. It originated in studies of historical US portfolio returns over 30-year retirements. Whether it is safe for you depends on how long you live, what you are invested in, what charges you pay, and — significantly — what markets do in the first few years, since poor early returns combined with withdrawals do disproportionate damage. Many advisers now suggest something closer to 3% to 3.5% for a long retirement.
Should I buy an annuity instead?
It depends on how much certainty you want. An annuity gives a guaranteed income for life and removes the risk of outliving your money, at the cost of flexibility and of leaving the capital to your estate. Rates improve with age and with health conditions, so an enhanced annuity may be worth considerably more than a standard quote. Many people now cover essential spending with an annuity or the State Pension and use drawdown for the rest.
How is pension income taxed?
Usually 25% of the pot can be taken tax-free, either as a lump sum or spread across withdrawals. The remainder is taxed as income at your marginal rate. Taking a large amount in one tax year can push you into a higher band, so spreading withdrawals across tax years is often more efficient.
When can I access my pension?
The normal minimum pension age is currently 55, rising to 57 in 2028. Some older schemes have protected earlier ages. Accessing a pension early through anything other than the scheme itself is almost always a scam — pension liberation schemes carry punitive tax charges and have cost people their entire savings.
Where can I get free help?
