25 / 25 · After-Tax Return

She does not stop at the headline return. She asks what is left after the costs and taxes that actually apply to her.

The money that compounds is the money left after tax, fees and other frictions. Tax timing is therefore part of the investment mechanism—not a line to consider only at the end.

The lesson

€10,000 can become €100,627 at 8% gross—or €51,276 at 5.6%.

This deliberately simple illustration converts an 8% gross annual return into 5.6% by applying a 30% levy to each year's gain. Over thirty years, €10,000 reaches €100,627 at 8% and €51,276 at 5.6%.

The €49,351 gap does not describe a real tax system. Tax may be applied at sale, annually, on income, on gains, differently across account types, or not at all in a particular circumstance.

That variation is exactly the lesson. Before comparing returns, identify the return that can remain invested after the rules that apply to you.

Ask better after-tax-return questions

Help me create questions for a qualified local tax professional about an investment or account. Ask for my tax residence, account type, asset type, expected holding period, whether gains or income are taxed, timing of tax, fees, losses, allowances and the objective of the investment. Do not calculate my tax or recommend a product.

Assumptions

  • The illustration represents tax only as a constant lower annual rate, which real tax systems do not generally use.
  • It excludes fees, inflation, gains and losses, tax allowances, tax timing, account rules, residence and changes in law.
  • Use qualified local tax advice for an actual financial decision.
