Inflation means the same money buys less over time. This calculator compounds the average annual inflation rate you enter to show the future buying power of an amount, what the same basket will cost and the total price increase. It gives a quick sense of scale when you think about pay rises, rent or savings goals.
You set the rate here, and real inflation varies from year to year and between countries. For exact figures, use your country's official consumer price index. The calculation runs in your browser and the amounts you type are not stored; you can ask Ryna to explain the result.

What is a past amount worth today?
The most-asked inflation question looks backwards, not forwards: "what does the basket 1,000 bought in 2015 cost now?" That calculation does not use an assumed rate but the official consumer price index, and the formula is: today's equivalent = past amount × (index of the target month ÷ index of the starting month). The calculator on this page works from a fixed rate you supply, so it is an estimate. For a month-by-month calculation on the real Turkish CPI, use the Inflation Calculator inside Ryna: it pulls the index from the TurkStat series in the central bank's EVDS system and states which month's data it used.
Nominal value, real value and buying power
Nominal value is the number printed on the money; real value is how much that number actually buys. In a year when your pay rises 40% and inflation runs 50%, you gained nominally and lost in real terms — the real change is roughly (1.40 ÷ 1.50) − 1 = −6.7%. The same logic applies to savings: when a deposit yields less than inflation, the balance grows while its buying power shrinks. The "in today's money" line in the savings calculator shows exactly this.
Frequently asked questions
How do you calculate inflation over several years?
The amount is multiplied by (1 + annual inflation) for each year to get the future price of the same basket; dividing the amount by that factor gives its future buying power. The calculator applies this compound effect over the years you enter.
Why does my result differ from official figures?
Official inflation is measured with a consumer price index that changes every month, while this page applies one average rate you choose. Use your country's official index for exact historical figures.
Is inflation the same for everyone?
No. Official inflation reflects an average basket; your personal inflation depends on what you spend on, such as rent, food or transport.
