Perguntas Frequentes
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.
