Takeaway

A wide result range signals that the decision should not rely on one return forecast.

Interpret future value in purchasing-power terms

A larger nominal balance may not represent the same future spending power after inflation and taxes.

  • Use net-of-fee growth assumptions.
  • Compare nominal and inflation-adjusted results.
  • Do not treat steady compounding as guaranteed.
