Income Drawdown Calculator (UK)
See how long your pension pot could last based on your planned annual withdrawals and expected investment returns.
Your details
The total value of the pension savings you plan to draw from.
How much you plan to take out each year.
A long-term average growth rate on the remaining pot. 4–5% is a commonly used cautious estimate.

How this works
This is a projection, so treat every figure as an estimate rather than a guarantee.
We model your pot one year at a time. In each year we:
- Take your withdrawal first — the lower of your planned annual withdrawal or whatever is left in the pot.
- Grow what remains — the balance after that withdrawal is grown by your expected annual return.
We repeat this until the pot is exhausted or until we reach a 60-year horizon. If the pot survives all 60 years we report "60+ years".
The withdrawal rate is your first-year withdrawal as a percentage of your starting pot, and drives the sustainability rating:
- 3% or less — Very Sustainable
- Over 3% up to 4% — Sustainable
- Over 4% up to 5% — Moderate Risk
- Over 5% up to 6% — Higher Risk
- Over 6% — High Risk
Assumptions
- Figures are estimates from a simplified year-by-year projection — real outcomes will vary.
- Growth is a constant annual rate applied after each year's withdrawal. Real returns vary year to year, and a poor run of returns early in retirement can deplete a pot far faster.
- Withdrawals are assumed to stay level in cash terms; inflation is not accounted for, so the spending power of a fixed withdrawal falls over time.
- Tax, charges, the State Pension, and any other income are ignored.
- The projection stops at 60 years; a "60+ years" result does not mean the pot lasts forever.
