Video transcript

Adjusting for changing prices helps maintain the value of transactions or investments over time due to inflation. Use the Consumer Price Index (CPI) to convert past prices to present-day equivalents. Simply multiply the original amount by the ratio of the current CPI to the past CPI. This ensures your financial decisions are relevant and up-to-date, providing accurate comparisons and better budgeting. For example, if the CPI doubled since a purchase, you’d multiply the original cost by 2 to understand its current value.
