Calculate With Full ToolWhat is Compound Interest with Inflation Adjustment?
Compound interest with inflation adjustment calculates real investment returns by accounting for the impact of inflation. This shows your true purchasing power and helps you make informed investment decisions by revealing whether your investments are actually growing in real terms.
How Inflation Adjustment Works
The formula adjusts nominal returns by subtracting inflation rate, showing real return after accounting for purchasing power. This helps you understand if your investments are truly beating inflation or just keeping pace with rising prices.
Why Inflation Adjustment Matters
Inflation silently erodes investment returns. Understanding real returns helps with financial planning, retirement savings, and investment selection. It is crucial for long-term wealth preservation and growth.
Inflation Adjusted Return Formula
Real Return = [(1 + Nominal Return) ÷ (1 + Inflation Rate)] - 1
Nominal Return: (Future Value ÷ Initial Investment - 1) × 100
Inflation Rate: Annual inflation percentage (as decimal)
Real Return: Adjusted return showing purchasing power
Purchasing Power Loss: 1 - (Real Return ÷ Nominal Return)
Future Value: Initial Investment × (1 + r)^n
Adjusted Future Value: Initial Investment × (1 + r)^n × (1 - i)
Step-by-Step Example
Example: $10,000 at 7% with 3% Inflation
Step 1: Initial Investment: $10,000
Step 2: Nominal Return: 7% annually
Step 3: Inflation Rate: 3% annually
Step 4: Real Return: [(1 + 0.07) ÷ (1 + 0.03)] - 1 = 3.88%
Step 5: Purchasing Power Loss: 1 - (0.0388 ÷ 0.07) = 3.12%
Step 6: Real Annual Return: 3.88% - 3% = 0.88%
Step 7: Future Value: $10,000 × (1.07)^10 = $19,671
Step 8: Adjusted Future Value: $10,000 × (1.07)^10 × (1 - 0.03) = $16,345
This example shows how 3% inflation reduces a 7% nominal return to 3.88% real return, with $3,326 less purchasing power over 10 years. The adjusted future value is $16,345 instead of $19,671 when accounting for inflation.
