วิธีการคำนวณ Greedflation Price Check
learn.whatIsHeading
The Greedflation Price Check Calculator compares current product prices to inflation-adjusted reference prices to identify excess increases attributable to corporate profit margins rather than input costs. Inflation-adjusted price = old price × (1 + inflation rate)^years. Anything above is potential greedflation. Useful for consumers, journalists, and policy analysts.
