Part I · Foundations and 2026 estimates
The PCPI in Brief.
The People are the grassroots at the bottom of the social pyramid, whose budgets are disproportionately committed to unavoidable necessities such as food, housing, electricity, transport and insurance. The official CPI is mathematically valid, but as a population-wide weighted average it does not necessarily represent the inflation actually experienced by the People.
The PCPI is therefore supplementary, not a replacement for the CPI: its purpose is to reveal the price pressure on the necessities dominating grassroots budgets and thus the reality of purchasing power at the bottom.
For the general CPI with unequal expenditure weights:
i: the individual consumption category or item.
n: the total number of categories/items included in the CPI basket.
w(i): the population-wide expenditure weight assigned to category (i), reflecting its share in total household consumption expenditure.
I(i): the price index, or price-relative measure, for category i.
CPI: the overall weighted Consumer Price Index.
The People’s Consumer Price Index uses equal weights across the five selected necessities:
i: one of the five selected necessity categories.
5: the number of necessity categories included in the present PCPI.
1/5: equal weight of 20% assigned to each category.
ΔPi: percentage price change of necessity category i over the period examined.
PCPI: the unweighted arithmetic mean of the five necessity-price changes.
For the Greek PCPI used in the reports:
Where E = electricity, F = fuel, I = insurance, M = food and non-alcoholic beverages, and R = paid rent.
The terms ΔPi are the inflation rates for the five necessity categories. So the resulting PCPI is itself a grassroots inflation rate for the given period.
For Greece 2020–2025:
The PCPI formula directly produces the PCPI inflation rate because its inputs are already percentage price changes:
For maximum mathematical consistency, we may call it PCPI inflation rather than simply “PCPI” when the result is expressed as a percentage change such as 26.64%.
Thus official CPI ≠ necessarily THE PEOPLE’S cost of living. Wage growth must ultimately be judged against necessity prices and real disposable purchasing power, not nominal increases alone.
The grassroots index PCPI comes in at an estimated 5.14%, compared with an estimated ELSTAT CPI of 3.88%. Since median wage growth is provisionally estimated at 5.06%, ordinary wage earners under the People’s model experience approximately a -0.08% change in purchasing power in 2026 — effectively stagnation rather than the positive real-wage growth produced by the aggregate equation.
Important note on the missing median-wage variable.
For the corrected equation, the appropriate income variable is median wage growth, rather than an aggregate or average wage measure. However, a directly observed Greek median wage for 2025–2026 is not yet available.
Eurostat obtains detailed median earnings from the Structure of Earnings Survey (SES), which is conducted only every four years. The latest available survey is for 2022; Eurostat reports Greek median gross hourly earnings of €8.00 per hour for that year. The Eurostat hourly-earnings dataset currently ends in 2022. Structure of earnings survey 2022
Therefore, the 2026 median-wage growth used here must be estimated.
The closest current ELSTAT measure is the Index of Wages Cost, measuring gross hourly earnings for Sections B–S of the economy. For the working-day-adjusted series:

130.5 |
117.8 |
135.6 |
ELSTAT reports Q1 growth of 6.4% and Q2 growth of 3.9%. ELSTAT - INDEX OF WAGES COST
Rather than simply averaging those two percentage rates, the H1 index levels are compared:
Thus: Estimated median-wage growth 2026 = +5.06%
This estimate assumes that the median wage has moved approximately in proportion to ELSTAT's aggregate hourly wage-cost index, that H1 2026 is reasonably representative of the year as a whole, and that changes in the wage distribution have not caused the median to move substantially differently from the aggregate index. It is therefore explicitly an estimate, to be replaced when a new observed median becomes available through the periodic SES. ELSTAT itself defines its Wage Cost Index as an index of hourly wages based on gross earnings divided by hours worked; it is not a median-wage statistic. Structure of earnings survey 2022

Provisional insurance proxy. In August, motor-vehicle insurance was +1.9% and private health insurance +7.0%. |
Food and non-alcoholic beverages |
+2.08% |
Based on the annual-average trajectory through August; the group itself stood +0.9% YoY in August. |
Paid rent |

Rental inflation remains strong; ELSTAT recorded +6.2% YoY for rentals for dwellings in August. |
The point-in-time August changes above are published directly by ELSTAT.
The annual-average 2026 figures in the table are estimates, not ELSTAT or Eurostat forecasts. January–August use available price-index observations; September–December are mechanically extrapolated using the latest available annual movement: combining realised data with a transparent estimate for the unfinished part of the year.
There is an additional qualification for insurance. From January 2026 Eurostat introduced ECOICOP version 2 and rebased HICP to 2025=100. Insurance and financial services now form a separate division, so the insurance series carries a greater comparability risk across the 2025/2026 classification boundary than the other four components.
Calculation of PCPI for 2026.
The unweighted arithmetic mean of the estimated market-price changes gives the following estimate for the Greek People’s Consumer Price Index (PCPI):
Thus, using the estimated median-wage increase:
5.06% - 5.14% =
Under this methodology, ordinary wage earners experience essentially no real-income growth in 2026, with a small estimated purchasing-power decline of approximately 0.08%.

The historical values are based on Eurostat HICP component series and rebased so that 2025 = 100, allowing the five categories to be compared on the same scale. Eurostat defines an annual-average HICP index as the average of the twelve monthly indices for the calendar year. HICP - annual data (average index and rate of change) (1996-2025)

*The insurance series should be treated as the least certain of the five because of the 2026 ECOICOP classification change. Historical Eurostat annual HICP data are available through 2025, while 2026 remains incomplete and is therefore estimated.
The Greek grassroots index PCPI is provisionally estimated at 5.14% for 2026, compared with an estimated 3.88% full-year ELSTAT national CPI.
ELSTAT's latest directly published national CPI shows 3.8% annual inflation in August 2026 and a 3.4% twelve-month average increase for September 2025–August 2026. Since the year is not yet complete, the 3.88% full-year figure is estimated from the eight published months plus an extrapolation for September–December; it is not an ELSTAT forecast.
The estimated full-year CPI is calculated by taking ELSTAT's actual January–August indices and, provisionally, carrying August's 3.8% annual rate through the corresponding September–December 2025 indices. This yields an estimated 2026 annual-average CPI index of approximately 125.60, compared with 120.91 in 2025, or:

Summary of the “false” versus the corrected equation.
Here, “false” does not mean ELSTAT's statistics are fabricated. It means that an aggregate wage measure combined with a population-wide CPI is regarded as an inappropriate measure of the purchasing power of the People specifically.

The equality of the two wage figures is temporary and methodological, not evidence that average and median wages are actually growing identically. The official side uses ELSTAT's aggregate Wage Cost Index directly. The People's side requires the median, but because the directly observed median is published only through the periodic four-yearly SES and the latest observation is 2022, the same wage-cost movement is provisionally used to estimate the median's 2025→2026 growth.

This produces the central contrast:1
versus:
This shows why many people may experience their wallets becoming emptier—or at least no meaningful improvement in purchasing power—even when aggregate statistics and news reports indicate solid real-wage growth.
