In today's money. The model increases it with inflation each year.
£12,548 is the full new State Pension. Most people get less — check your forecast.
Withdrawals are split between the two pots each year to keep the household's tax bill as low as possible — using both personal allowances before either of you pays a higher rate.
The new State Pension cannot be inherited. On first death the household permanently loses one State Pension and one personal allowance — but the bills don't halve.
…of the couple's income. 67% is the standard equivalence scale. Housing, heating and council tax barely move.
Tax-free cash spent elsewhere is not available to fund income later. In this model that changes the outcome more than any other single input.
Nothing here is a fact. These are the numbers that decide the answer, so they belong to you, not to us.
5% nominal less 2% inflation = 2.94% a year after inflation.
The FCA prescribes returns but not volatility. This one is a guess — ours or yours, but a guess.
Most calculators never say which. Under one convention volatility lowers the compound return; under the other it does not. The two give different answers.
Frozen bands shrink in real terms every year — "fiscal drag". Current policy is a freeze, so 0 is the optimistic setting.
