What Oakspan does
Oakspan shows how far a SIPP or workplace defined-contribution pot may stretch in drawdown. You set the pot, contributions, retirement age, income and growth. The figures stay in your browser. The result is an illustration using 2026/27 England, Wales and Northern Ireland tax bands — not personal advice, and not a scheme quote.
Start with the calculator, then read the guide and the 2026/27 rates the model uses.
Other tools from the studio
