如何使用这个Inflation Calculator模板
Enter the dollar amount
Input a starting amount in today dollars that you want to project forward or backward for inflation impact.
Set the inflation rate
Enter an annual inflation rate percentage. Historical averages range from 2% to 4%, but you can use any rate.
Choose the time period
Enter the number of years to project. The calculator works both forward (future value) and backward (past value).
Read purchasing power
The results show how much the original amount is worth in future or past dollars, and the multi-year table shows the erosion year by year.

常见问题
What inflation rate should I use?
The long-term US average is roughly 3% per year. Use higher rates for conservative planning or lower rates for recent low-inflation periods.
Can I project backward in time?
Yes. The calculator works in both directions. Enter a past year count to see what a historical amount would be worth in today dollars.
Does it compound the inflation?
Yes. Inflation compounds annually, meaning each year reduction is applied to the already-reduced value from the prior year.
Is this useful for retirement planning?
Yes. Understanding inflation impact helps estimate future living costs and the real value of retirement savings over a long time horizon.
