Understanding Purchasing Power
Purchasing power represents the real value of money in terms of goods and services it can buy. Inflation reduces purchasing power over time, meaning a dollar today will buy less in the future. Understanding purchasing power is essential for financial planning and investment decisions.
Purchasing Power Calculations
Future Purchasing Power
- Future Value = Current Value × (1 + i)^(-n)
- Shows what current dollars are worth in future
- Negative exponent because inflation reduces value
- Essential for retirement planning
Present Value of Future Money
- Present Value = Future Value × (1 + i)^(-n)
- Shows what future dollars are worth today
- Adjusts for inflation to find real value
- Important for investment analysis
Real vs Nominal Values

- Not adjusted for inflation
- Face value or stated value
- Can be misleading over time
- Used in contracts and statements
Real Values
- Adjusted for inflation
- Reflects actual purchasing power
- More accurate for comparisons
- Essential for long-term planning
