What is Inflation?

The related concept is inflation and purchasing power. Inflation measures how prices rise over time, decreasing the value of money. Understanding inflation allows individuals, businesses, and investors to plan spending, saving, and investing strategies effectively.

Formula & Equations Used

Future Value Considering Inflation:
FV = PV × (1 + i)
t
Where:
FV = Future Value adjusted for inflation
PV = Present Value (current amount)
i = Annual inflation rate (as a decimal)
t = Number of years
────────────────────────
This formula lets you see the equivalent value of money across different years, factoring in inflation.

Step-by-Step Worked Example

Example: Inflation Adjustment
Current amount (PV): $1,000
Average annual inflation rate (i): 3% → 0.03
Number of years (t): 10
FV = 1000 × (1 + 0.03)
10
= 1000 × 1.3439 ≈ 1,344
Result: $1,000 today will require approximately $1,344 in 10 years to maintain the same purchasing power.
