1. What is Loss of Purchasing Power?

Loss of purchasing power refers to the decrease in the amount of goods and services that can be purchased with a fixed amount of money over time, primarily due to inflation. This calculator helps quantify how inflation erodes the real value of money.

2. How Does the Calculator Work?

The calculator uses the inflation adjustment formula:

\[ \text{Adjusted Amount} = \frac{\text{Original Amount}}{(1 + \text{Inflation Rate})^n} \]

Where:

\( \text{Original Amount} \) — Initial amount of money in dollars
\( \text{Inflation Rate} \) — Annual inflation rate as a percentage
\( n \) — Number of years

Explanation: The formula calculates the present value equivalent of a future amount, showing how much purchasing power is lost due to inflation over time.

3. Importance of Inflation Adjustment

Details: Understanding loss of purchasing power is crucial for financial planning, retirement savings, investment decisions, and maintaining real wealth over time. It helps individuals and businesses make informed decisions about savings and expenditures.

4. Using the Calculator

Tips: Enter the original amount in dollars, annual inflation rate as a percentage, and the number of years. All values must be valid (amount > 0, inflation rate ≥ 0, years between 0-100).

5. Frequently Asked Questions (FAQ)

Q1: What is considered a normal inflation rate?
A: Most central banks target 2-3% annual inflation. Rates above 5% are considered high inflation, while hyperinflation exceeds 50% per month.

Q2: How does inflation affect savings?
A: If savings earn less interest than the inflation rate, the real value of savings decreases over time, resulting in loss of purchasing power.

Q3: Can purchasing power increase?
A: Yes, during deflation (negative inflation) or if investments earn returns higher than the inflation rate, purchasing power can increase.

Q4: How accurate is this calculation?
A: This provides a theoretical estimate assuming constant inflation. Real-world inflation rates fluctuate annually.

Q5: What investments protect against inflation?
A: Real estate, stocks, Treasury Inflation-Protected Securities (TIPS), and commodities often provide inflation protection.
