Plan your retirement with confidence
A UK-specific retirement calculator that models your savings, pensions, tax, and drawdown strategy — month by month, pound by pound.
Who is this plan for?
Choose whether this is a single-person or couple plan. Couple plans model both users' pots, tax, and income separately.
Target retirement income
How much do you want to receive each month in retirement, after tax?
Key assumptions
Core parameters that affect the entire projection.
Spending bands
Override the monthly income target for specific age ranges — e.g. a higher amount at 65 for travel, then a lower amount from 85. Amounts in today's money; inflation applied automatically. The base target above applies where no band is active.
Drawdown order
When B1 income falls short of your target, which pots are drawn from first? B1 always runs first. Drag or reorder B2–B6 below. This setting is saved with each scenario.
User profiles
