How drawdown works

With flexi-access drawdown you leave your pension invested and take an income from it whenever you like. You can normally take 25% tax-free up front, and the remaining 75% stays invested. The trade-off versus an annuity is that you keep flexibility and growth potential, but you also carry the risk that markets fall or you live longer than your money lasts.

Withdrawal rateRough longevity
3% a yearVery likely to last 30+ years
4% a yearOften considered sustainable
6% a yearMay exhaust in ~20 years
8% a yearHigh risk of running out
Sequence-of-returns risk is real. A market crash in your first few drawdown years does far more damage than the same crash later, because you're selling units while they're cheap. Many people hold a cash buffer to avoid drawing during downturns.

Tax and the State Pension

Drawdown income above your Personal Allowance is taxed — model it on the income tax calculator. Most retirees also receive the State Pension, which uses up part of your allowance first. If you prefer certainty, compare the guaranteed alternative on the annuity calculator.

Drawdown FAQs

How long will my pension pot last in drawdown?

It depends on pot, income and growth. Drawing ~4% a year is often sustainable for around 30 years; 6–7% can exhaust a pot in 15–20 years.

What is pension drawdown?

Keeping the pot invested and taking a flexible income, after up to 25% tax-free cash. You control withdrawals but carry the risk.

Is drawdown income taxed?

Yes — beyond the 25% tax-free cash, income is taxed at your marginal rate.

Can I switch from drawdown to an annuity later?

Yes — many people use drawdown early in retirement and buy an annuity later, when rates are typically higher with age.
