Understanding the Impact of Inflation
Inflation is the rate at which the general level of prices for goods and services rises, and subsequently, purchasing power falls. Central banks attempt to limit inflation, and avoid deflation, in order to keep the economy running smoothly. For consumers, inflation means that the same amount of money will buy fewer goods in the future than it does today.
How Future Inflation is Calculated
This calculator uses the compound inflation formula to project future costs. The math behind the calculation is as follows:
Real-World Example
Suppose you currently spend $5,000 per month on living expenses. If the average annual inflation rate is 3%, let's look at how much that same lifestyle will cost in 20 years:
- Current Monthly Cost: $5,000
- Inflation Rate: 3% (0.03)
- Timeframe: 20 Years
- Calculation: $5,000 × (1 + 0.03)^20 = $9,030.56
In this scenario, you would need over $9,000 a month in two decades just to maintain the same standard of living you have today for $5,000.
Why This Matters for Your Savings
If you are saving for a long-term goal, such as retirement or a child's education, you must account for inflation. If your savings account offers a 2% interest rate but inflation is 3%, you are effectively losing 1% of your purchasing power every year. To grow your wealth, your "Real Rate of Return" (Interest Rate minus Inflation Rate) must be positive.
Historical Context
Historically, in the United States, the long-term average inflation rate has hovered around 3% annually. However, this can fluctuate wildly due to economic cycles, supply chain disruptions, and monetary policy. In the late 1970s and early 1980s, inflation peaked in the double digits, significantly eroding the value of cash savings during that era.
