Inflation Calculator

Overview

An inflation calculator shows how the buying power of money changes across years — what $100 in the past is worth today, or what today's money will feel like in the future. Because prices rise over time, the same amount buys less each year, and this tool makes that shift concrete. It computes the adjustment instantly in your browser using inflation-rate data, with nothing sent to a server.

How to Use (Step by Step)

1. 1

   Enter an amount and years

   Type the sum, the starting year, and the year you want to compare it to.

2. 2

   Let it apply the inflation rate

   The tool compounds the rate across the period and calculates the equivalent value.

3. 3

   Read the adjusted amount

   See what your money is worth in the target year, showing how buying power changed.

How It Works

The calculator compounds an inflation rate across the years between your start and end points. Enter an amount, a starting year, and an ending year, and it applies the cumulative rate to show the equivalent value — for example, translating a past salary into today's dollars. The math is a year-by-year compounding, done locally, so your figures stay private.

When to Use This

Understanding how much a historical price or salary is worth in today's money. Checking whether a raise actually keeps up with rising costs. Estimating what a future expense (like tuition or retirement spending) might cost. Comparing prices across decades fairly. Judging whether an investment beat inflation. Putting an old number in context for a report or article.
