Inflation Calculator (Turkey)
Purchasing power across years, from official Turkish CPI figures.
TRY 10,000 in 2020 is roughly equivalent to TRY 69,605.60 of purchasing power in 2025 (cumulative inflation 596.06%).

Inflation erodes the purchasing power of money: the same amount of Turkish lira buys less and less as years pass. This tool uses the official series of annual (December-to-December) CPI changes published by TurkStat (TÜİK) to compute cumulative inflation between any two years, and shows what an amount is worth in both directions — what an old amount corresponds to today, and what a current amount would have been back then. The series reaches back to 2005 and is updated automatically from the parameter store.
How is it calculated?
The calculation compounds the annual CPI rates:
- Cumulative multiplier: for every year after the start year up to and including the end year, the factor
(1 + that year's CPI rate)is multiplied in. Rates are compounded, never added. - End-year equivalent: the amount you enter is multiplied by the cumulative multiplier and rounded to the kuruş. This is what the start-year money would need to become to keep the same purchasing power in the end year.
- Reverse direction: the same amount taken from the end year back to the start year is found by dividing by the multiplier.
The rates used are the year-over-year changes as of each December — a different series from the "12-month averages" figure used for rent increases. If you select the same start and end year, the multiplier is 1 and the amount stays unchanged.

Example
If you are wondering what a sum you set aside a few years ago is worth in today's purchasing power, just enter the amount and pick the start and end years. The tool shows both the present-day equivalent of the old money and the reverse — what a present-day amount corresponds to in the earlier year. Across consecutive high-inflation years you will notice the cumulative result is clearly larger than the simple sum of the yearly rates; that is because the rates compound multiplicatively.
Frequently asked questions
How is inflation between two years calculated?
The amount is increased by each year's CPI rate in sequence, so the rates are applied compounded rather than added. The resulting cumulative multiplier times the amount gives the purchasing-power equivalent in the end year.
Which inflation data does this tool use?
It uses the annual consumer price index (CPI) changes published by TurkStat, measured December over December; the series is kept in the parameter store together with its official source. Producer prices (PPI), alternative gauges such as ENAG, or monthly index levels are not used here.
What does cumulative inflation mean?
It is the total percentage rise in prices between the two selected years. It is not the sum of the yearly rates; because each year's rate compounds on top of the previous ones, the cumulative figure comes out larger than the simple total.
What does the purchasing-power equivalent mean?
It is the amount the start-year money would need to reach in the end year to buy the same basket of goods and services. If the result is double the input, prices doubled over that span and the money's purchasing power halved.
What happens if I pick the same start and end year?
The multiplier becomes 1 and the amount does not change; cumulative inflation shows as 0%. Pick two different years for a meaningful comparison.
Why does the result differ from the inflation I feel?
CPI tracks the price change of an average consumption basket; if your own spending mix (rent, education, food weight) differs from the average, the inflation you experience will differ too. The tool calculates with the official series, so personal results may vary.
Which years does the series cover?
The series starts in 2005 and runs to the latest completed year that has been announced; the years offered in the dropdowns are generated directly from the series in the parameter store. When a new year's figure is published, the store is updated and the tool offers the new year automatically.
