Assumptions

Calculation notes

  • This simplified model does not calculate exact income tax, CGT, platform fees, sequence-of-return risk, inflation changes, state pension, property, or drawdown rules.
  • Use the tax and fees buffer to add a broad margin when your portfolio will not be entirely inside tax wrappers.
  • A constant annual return is used for illustration.
  • This is planning maths, not financial advice.
