What is flexi-access drawdown?

UK pension flexibility allowing pension pot to remain invested while withdrawing an income (no cap). Triggered when first drawdown withdrawal is made. Once in flexi-access drawdown, the Money Purchase Annual Allowance (MPAA) of £10,000 applies.

How long will my drawdown pot last?

Duration = - [ln(1 - (V x r / W)) / ln(1 + r)], where V is initial portfolio, r is real return per period, W is annual withdrawal. At 0% real return, pot lasts V/W years. At positive returns, it lasts longer (potentially forever at low withdrawal rates).

What is UFPLS (Uncrystallised Funds Pension Lump Sum)?

UFPLS allows withdrawing from a pension pot where 25% of each withdrawal is tax-free (not a single 25% lump sum upfront). Flexible way to manage tax-free entitlement alongside drawdown. Each withdrawal triggers MPAA.

How does phased retirement work?

Crystallise pension in stages rather than all at once. Take a portion of the tax-free cash and designate a portion to drawdown each year as needed. Uncrystallised portion continues to grow in tax-privileged wrapper.

What is the Annual Allowance (MPAA) in drawdown?

Once you access flexible drawdown benefits (flexi-access or UFPLS), your annual pension contribution allowance falls from £60,000 to £10,000 (Money Purchase Annual Allowance). Defined benefit accrual is still allowed up to £60,000.
