What is an Inflation Calculator?
An inflation calculator is a financial tool that estimates the changing value of money over time. It calculates how purchasing power erodes and how much a specific dollar amount from the past or present will be worth in the future, based on a given annual inflation rate.
Understanding inflation is critical for long-term retirement planning, as it helps you determine the "real" value of your future savings and how much more you will need to spend to maintain your current standard of living.
