Report for: April 2011 — March 2026

Moderate (creeping) inflation was recorded with an average annual rate of 3.5%. This is the standard operating mode for most economies, stimulating consumption. However, over time, this rate leads to a logical erosion of capital: the total cost of living increased by 1.69 times, reducing the real value of PLN to 59%.

Equivalent Value
What cost 100 PLN in 2011, would cost 169 PLN today. To maintain the same standard of living, income over 15 years should have grown by 1.69 times.

Calculation Methodology

Calculations are based on CPI GUS. It is a consumer price index that measures the average change in prices for goods and services purchased by the population.

Price Multiplier

Price Multiplier shows how many times prices have increased. In macroeconomics, this baseline metric is known as the Price Index Ratio. It is derived directly from official CPI data and serves as the mathematical foundation for all other calculations on this page.

Formula:
Price Multiplier(K)=CPI2026CPI2011\text{Price Multiplier} (K) = \frac{\text{CPI}_{2026}}{\text{CPI}_{2011}}
Calculation:
370362.933219611.366=1.6864\frac{370362.933}{219611.366} = 1.6864
Cumulative Inflation

To calculate the cumulative inflation since 2011, we use the following formula:

Formula:
(K−1)×100=Cumulative(%)(K - 1) \times 100 = \text{Cumulative} (\%)
Calculation:
(1.6864−1)×100=68.6%(1.6864 - 1) \times 100 = 68.6\%
Average Inflation Rate

Shows the average annual price growth rate including compound interest (where each year's inflation is added to already increased prices). To calculate the average annual inflation for 15 years since 2011, we use the following formula:

Formula:
K1n−1=Average Inflation RateK^{\frac{1}{n}} - 1 = \text{Average Inflation Rate}
n — number of years (15)
Calculation:
(1.68641/15−1)×100=3.5%(1.6864^{1/15} - 1) \times 100 = 3.5\%
Loss of Buying Power

To find out what share of its real value savings in PLN have lost since 2011, we calculate the percentage drop in purchasing power. Loss of buying power is calculated as an inverse proportion to price growth:

Formula:
(1−1K)×100=Loss of Buying Power(%)\left( 1 - \frac{1}{K} \right) \times 100 = \text{Loss of Buying Power} (\%)
Calculation:
(1−11.6864)×100=40.7%\left( 1 - \frac{1}{1.6864} \right) \times 100 = 40.7\%
Equivalent Value

To calculate the equivalent value in terms of purchasing power in 2026, we multiply the initial value from 2011 by the price growth factor:

Formula:
Original Amount×K=Equivalent\text{Original Amount} \times K = \text{Equivalent}
Calculation:
100×1.6864=169 PLN100 \times 1.6864 = 169 \text{ PLN}
