Calculating Your Need

Simple Formula

1	Choose retirement income target
2	Subtract State Pension forecast
3	= Annual shortfall
4	Shortfall × 25 = Pot needed

Example

Step	Amount
Target income	£30,000/year
State Pension	-£11,500
Shortfall	£18,500/year
× 25	£462,500 pot needed

The 25× Rule (4% Rule)

Concept	Details
Sustainable withdrawal	4% per year
£100,000 pot	= £4,000/year
£500,000 pot	= £20,000/year
Assumes	30-year retirement
Origins	US research, adjust for UK

Pot Size Examples

How Much You Could Get
