A £100,000 pension pot drawn at 4% a year gives £4,000 a year before tax. Add the full new State Pension (£241.30 a week, about £12,548 a year) and the total is about £16,548 a year before tax. The 4% rate is an assumption this page uses to illustrate the arithmetic, not a guaranteed or recommended rate.
Income from £100K Pension
Annuity Option (Guaranteed Income)
An annuity is a product, usually bought from an insurance company, that gives you a guaranteed income for life. The amount depends on how long the insurer expects you to live and how many years it expects to pay you. Insurers take into account your age and gender, the size of your pot, interest rates and sometimes your health. Some annuities pay for a fixed time instead of for life, and some continue paying your spouse or partner after you die.
Because annuity rates change with interest rates and differ by provider and health, this page does not quote an annuity income for a £100,000 pot. Providers can give you a quote, and you do not have to buy your annuity from your own pension provider.
Drawdown Option (Flexible)
With flexi-access drawdown, your pot stays invested and you take money out as you need it. The table applies three withdrawal rates to the starting pot. It is arithmetic only: it ignores investment returns, charges and tax, and an invested pot can fall as well as grow.
| Withdrawal Rate (Assumption) | Annual Withdrawal | Monthly Income |
|---|---|---|
| 3.5% | £3,500 | £292 |
| 4% | £4,000 | £333 |
| 5% | £5,000 | £417 |
How long a pot lasts depends on the returns it earns, the charges you pay and how much you take out each year.
Combined with State Pension
| Income Source | Annual Amount | Monthly Amount |
|---|---|---|
| State Pension (full) | £12,548 | £1,046 |
| Pension drawdown (4%) | £4,000 | £333 |
| Total | £16,548 | £1,379 |
Amounts are before tax. Your State Pension depends on your National Insurance record: if your record started after April 2016 you need 35 qualifying years for the full rate. Check your forecast with the State Pension calculator.
Is This Enough?
The Retirement Living Standards (yearly costs, not income):
| Standard | Single | Couple | £100K at 4% Plus State Pension(s) |
|---|---|---|---|
| Minimum | £13,900 | £22,500 | Above (single and couple) |
| Moderate | £32,700 | £45,400 | Below (single and couple) |
| Comfortable | £45,400 | £62,700 | Below (single and couple) |
For one person, £16,548 a year is about £2,648 above the minimum cost and about £16,152 below the moderate cost. A couple with this pot and two full State Pensions would have about £29,096 a year, above the £22,500 minimum for two. The standards are costs, not income, so tax may mean you need more.
How £100K Compares
The latest ONS age breakdown of private pension wealth (Great Britain, April 2018 to March 2020) covers people with some private pension wealth and includes defined benefit pensions, so it is not the same as the size of a defined contribution pot.
| Age | Median Private Pension Wealth | £100K Position |
|---|---|---|
| 35–44 | £31,400 | About 3.2x the median |
| 45–54 | £72,900 | About 1.4x the median |
| 55–64 | £133,800 | About 0.75x the median |
| 65–74 | £120,800 | About 0.8x the median |

Making £100K Work
Tax-Free Lump Sum
You can usually take up to 25% of a pension as a tax-free lump sum, up to a maximum of £268,275. The remaining 75% is usually taxed as income when you take it.
- Tax-free: £25,000
- Remaining pot: £75,000
- Income from £75K (4%): £3,000/year
Part-Time Work Supplement
| Part-Time Earnings | Annual Total (Before Tax) | Monthly Total |
|---|---|---|
| £5,000/year | £21,548 | £1,796 |
| £10,000/year | £26,548 | £2,212 |
| £15,000/year | £31,548 | £2,629 |
Totals add the full State Pension and £4,000 of drawdown to the earnings. Part-time work narrows the gap to the moderate standard (£32,700 for one person).
Building Beyond £100K
If you’re not yet retired and have £100K, the table shows what the pot would grow to under one illustrative assumption: 5% a year growth, compounded monthly, with the monthly addition paid at the end of each month. It ignores charges, tax relief and inflation, and actual returns can be lower or negative.
| Monthly Addition | Years | Final Pot (5% Growth) |
|---|---|---|
| £200 | 10 | £196,000 |
| £400 | 10 | £227,000 |
| £200 | 15 | £265,000 |
| £400 | 15 | £318,000 |
