How is it calculated?

Base series · period gyros/month · scenario start 1998

712.17 € ÷ 1.78 € ≈ 400 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.

Geometric interpolation

Interpolation between the inputs for 2002 and 2011, using the CPI path identified by the calculation rule.

Anchors used by the calculation: 20022011

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

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.

Compare: 2009 → 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.

2009 rank: 26–26 out of 50 years.

Rank one is the highest purchasing power. Published baseline: rank 26.

Minimum–maximum across cases: ≈400–402 per month.

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

2009 remains below 1976 in every selected case.

Where this figure comes from

Geometric interpolation. Interpolation between the inputs for 2002 and 2011, using the CPI path identified by the calculation rule.

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.

Calculation reviewed, sources not newly verified · 8 Sept 2026

Price
The price is calculated between the 2002 and 2011 anchors. It is not an independent market observation for this year. Weights use an implied price growth rate, which also depends on the 1998 estimate.
Date
The year identifies a point in the calculated series, not a newly collected price. Dating uncertainty in the anchor sources carries into the calculation.
Geography
Interpolation adds no shops or regions to the sample. It inherits the geographical coverage and assumptions of its anchors.
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.

Weights also depend on the estimate: 1998

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

    1.78 €

    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.

Menus, reports and regulations document contemporary prices and specifications. Market prices remain distinct from regulated prices. Open questions and hypothetical comparisons do not automatically change the index.

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.
