InflCalc is a focused calculator for comparing US-dollar purchasing power across history and exploring an inflation rate you choose.
HISTORICAL CPI-U
- Convert an amount between 1913 and 2024
- Use bundled CPI-U annual averages from the U.S. Bureau of Labor Statistics
- See the two index values, total price change and implied annual rate
- Swap years to examine either direction without interpolation or extrapolation
ASSUMED-RATE PROJECTION
- Explore future cost or today's equivalent
- Choose a rate from 0% to 15% and a horizon from 1 to 50 years
- Review a genuine year-by-year breakdown
- Projection values are assumptions you enter, not CPI data or forecasts
FULL ACCESS
InflCalc unlocks with a weekly or yearly subscription, or a one-time lifetime purchase. Full access includes both calculators, the complete bundled CPI series, the year-by-year projection, unlimited saved comparisons and text-file export. Prices, billing periods and availability are supplied by Apple. An introductory offer appears only when the App Store confirms both an offer and eligibility for your Apple Account.
PRIVATE AND CLEAR
Inputs, settings and saved comparisons stay on this device. InflCalc has no account, advertising or analytics SDK and does not collect personal data. Optional reminders are scheduled locally by iOS. Historical data is bundled and attributed in the app.
InflCalc is for information only and is not financial, investment, tax or legal advice. Recent CPI values may be revised by BLS.
