Inflation Calculator
Calculate today’s purchasing power of a past amount using the TÜİK Consumer Price Index (CPI). Select two months, enter the amount, and see the total and average annual inflation.
How Is Inflation Calculated?
The inflation calculation is based on the ratio of the CPI index values of the two selected periods. The end month’s index is divided by the start month’s index; the resulting ratio is multiplied by the starting amount to find the current purchasing-power equivalent. For example, if the index has doubled, the money needed to buy the same item has also doubled.
Difference Between Total and Average Annual Inflation
Total inflation is the cumulative price increase over the entire period you selected. Average annual (compound) inflation is the average rate of that increase spread over the years; it is more meaningful when comparing long periods.
Loss of TL Purchasing Power
Purchasing-power loss shows what percentage less goods/services the same nominal amount buys at the end of the period. As inflation rises, the real value of cash held erodes by this rate.
