Gross minimum by month: Jan-Feb €751.39, Mar-Dec €586.08. Year mean €613.63. After contributions, before income tax. Annual income divided by 12, using 14 payments throughout the series. Wage and contributions are twelve-month means. Purchasing power in classic gyros.

Range from price bounds: 243–365 period gyros/month

How is it calculated?

Base series · period gyros/month · scenario start 1998

597.78 € ÷ 2.05 € ≈ 292 period gyros/month

After contributions, before income tax. Annual income divided by 12, using 14 payments throughout the series. Wage and contributions are twelve-month means. Purchasing power in period gyros.

The quotient is rounded to a whole number.

Only the price varies within its published bounds. Wage and composition stay fixed. This is neither a total uncertainty range nor a statistical confidence interval. Bounds come from the model's selected percentage band.

Asymmetric CPI pass-through

Model rule: carry forward non-negative catering CPI from the previous year and round to menu-price steps. This is not a new price observation.

The era view applies no meat-weight or composition rescaling to a classic product.

What do the sources support?

597.78 € ÷ 1.781 € ≈ 336 classic gyros/month

Historical meat weights and changes in composition are model assumptions, not a series of market measurements. The assumed peak and decline in portion size need verification. The present-day weight defines the reference product. The era price refers to the wrap sold at the time; the classic price and weight-adjusted index depend on these assumptions.

Both prices are expressed in money of the same year. Classic rescaling adjusts composition, not inflation.

What does the comparison assume?

Historical meat weights and changes in composition are model assumptions, not a series of market measurements. The assumed peak and decline in portion size need verification.

Compare 2012 with another year

Period and classic gyro prices, wage and purchasing power, with downloadable image and CSV.

Compare: 2012 → 2026

Which findings hold up?

We combine 2 wage bases, 4 historical-price choices and 7 composition specifications across 50 completed years, 1976–2025.

Counts are not probabilities. Payroll reconstruction remains under review. Portion scenarios are not measurements; geography and sale channel stay fixed.

Period gyros

8 distinct combinations. Portion assumptions do not affect this measure.

2012 rank: 37–37 out of 50 years.

Rank one is the highest purchasing power. Published baseline: rank 37.

Minimum–maximum across cases: ≈288–292 per month.

Extremes of the selected specifications, not an uncertainty interval. Ranks precede rounding of displayed counts.

2012 remains below 1976 in every selected case.

Where this figure comes from

Asymmetric CPI pass-through. Model rule: carry forward non-negative catering CPI from the previous year and round to menu-price steps. This is not a new price observation.

Catering CPI projection: 2.00 € (2011) × (1 + 2.2%) = 2.04 €. Menu-price step 0.05 €: 2.05 €.

The era price is an input or calculation in the series. Comparison in classic gyros adds assumptions about weight and composition.

Detailed evidence and calculation

What is supported for this year

We examine price, date, place and product composition separately. Evidence for the price does not establish historical meat weights.

The detailed year review is pending. This does not mean no sources exist.

Price
Sources and the calculation are shown below. A separate review of these dimensions has not yet been completed for this year.
Date
A separate check of publication date and observation date has not yet been completed here.
Geography
A separate review of geographical coverage and adjustments has not yet been completed here.
Composition
Historical meat weights and changes in composition are model assumptions, not a series of market measurements. The assumed peak and decline in portion size need verification. The present-day weight defines the reference product. The era price refers to the wrap sold at the time; the classic price and weight-adjusted index depend on these assumptions.

From source to series price

A source entry is not always the final price. These are the inputs retained by the model, without implying fresh verification of the original.

  1. 1. Amount before rescaling

    Not separately recorded

    The recorded original amount before any rescaling. It may be a regulated ceiling or composite input, not an individual purchase.

  2. 2. Model input

    No anchor for this year

    The price is calculated from other years and series rules. It is not presented as a new observation.

  3. 3. Period price in the series

    2.05 €

    The final price used for period purchasing power. Classic composition rescaling is a separate subsequent step.

In some years an anchor constrains the range rather than replacing the calculated price. Historical amounts use the fixed drachma-to-euro conversion, without inflation adjustment.

Ο Στέλιος · Αγνώστου Στρατιώτου 40, Πολίχνη

Charcoal gyro sandwich. The meat type is not explicitly specified.

2023-05

  • Base price: €3.50
  • Spread extra: €0.30
  • With spread: €3.80
  • Gyro portion: €8.00

The leaflet advertises a 10% online-order discount. It is not applied to this list-price comparison.

Change between the two menus: base price +29.63% · with spread +26.67% · portion +14.29%.

The 2019 menu is excluded from the change calculation because its price-increase stamp does not specify affected items.

The menus share a name, address and nominal product. Meat type, weight, recipe and ownership continuity are unverified. Dates follow archive captions. We compare printed prices before offers, not verified transaction prices. Portion-price changes do not measure quantity changes. This is neither an annual rate nor a representative city sample.

Research comparison; the model is unchanged.

Candidate source review

These menus were reviewed as potential sources for historical regional prices. They do not identify the legacy inputs and are not used in the model. Dates come from archive captions, not verified effective dates.

What the menus listed

Each item states its model use separately. Publishing this evidence does not change the series. A source amount is not the series annual price. This is a selected list, not an exhaustive inventory.

Base price and extra spread are recorded separately. Their sum does not establish the same recipe or portion size. Each record states its dating basis and what the image verifies. Discounts are not applied.
