Why does my €100K grow to €1,01M but only have the purchasing power of €479,73K in 30 years?

Over a 30-year period, compounding returns at 8% grow your initial €100K to €1,01M nominally. However, inflation at 2.5% annually compounds as well, reducing the value of money. In today's terms, that future sum will buy what €479,73K buys today, representing a 52.3% erosion in purchasing power.

How does a return rate of 8% beat an inflation rate of 2.5%?

Since your return rate (8%) exceeds the inflation rate (2.5%), your investment experiences real growth. The net purchasing power of your initial €100K increases to €479,73K (a real return of approximately 5.5% annually).

What is nominal future value vs real future value?

Nominal future value is the raw, unadjusted dollar figure your investments grow to over time. Real future value (or inflation-adjusted value) is what that future sum can actually buy in today's terms. It shows the true purchasing power after factoring in rising costs.

How does inflation impact long-term investments?

Inflation erodes the purchasing power of money. Over a 30-year period, a steady 3% inflation rate will cut the purchasing power of a lump sum by nearly 60%, meaning a $1,000,000 nominal corpus will only feel like $412,000 today.

Calculation Methodology & Formulas

The future value is calculated using two primary steps:

1. Nominal Future Value (FV_nominal):

FV_nominal = PV × (1 + r)ⁿ

2. Real Future Value (FV_real):

FV_real = FV_nominal / (1 + i)ⁿ = PV × [(1 + r) / (1 + i)]ⁿ

Where: PV = Present Value (initial amount), r = annual return rate, i = annual inflation rate, and n = duration in years.

The erosion of a $100,000 investment

Investing $100,000 at an 8% annual return rate for 30 years yields a nominal corpus of $1,006,265. However, at a standard 2.5% inflation rate, its purchasing power today is only $479,729, representing a 52.3% loss in value.
