Key point: This guide explains financial concepts and calculator logic. It does not tell you that one investment, loan, or retirement choice is right for you.
The two numbers answer different questions
Nominal return measures account growth; real return focuses on purchasing power after inflation.
Costs matter too
Fees, trading costs, and taxes may reduce what investors actually keep.
Avoid overly optimistic long-term projections
Extending a high nominal return for decades can make retirement projections look unrealistically easy.
Return is only half the picture
Volatility and the timing of losses also affect the investor experience.
How can you use this in practice?
Put the concept into a calculator and compare at least two or three scenarios. Focus on which assumptions drive the result.
