Series range: 0.587 € – 1.056 € · 280 GRD

The wrap of the period, at the historical series price. The price may be documented or estimated, as explained in the year’s sources.

Range from price bounds: 391–704 period gyros/month

How is it calculated?

Base series · period gyros/month · scenario start 1998

413.07 € ÷ 0.822 € ≈ 503 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 anchor's configured range.

Estimate with range

Selected estimate with a modelling range, without a directly documented price.

Wrapped-gyro estimate 280 GRD, range 200-360. The range is a model assumption, not a confidence interval. Earlier extrapolation arguments were: from below, the 1989 free-market price (75 GRD) carried forward with the catering CPI (about 207-260 GRD); from above, the 2001 euro-campaign indicative price (399 GRD) deflated back to 1998 (about 365 GRD). That value lies outside the stated range and the campaign date remains under review.

Anchors used by the calculation: 1998

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: 1998 → 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.

1998 rank: 23–23 out of 50 years.

Rank one is the highest purchasing power. Published baseline: rank 23.

Minimum–maximum across cases: ≈502–503 per month.

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

1998 remains below 1976 in every selected case.

Where this figure comes from

Estimate with range. Selected estimate with a modelling range, without a directly documented price.

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.

Reviewed with outstanding questions · 8 Sept 2026

Price
The price is a model estimate. Its range is a selected modelling bound, not a statistical confidence interval.
Date
No direct observation establishes the annual price. The estimate depends on earlier years and the euro campaign, whose date remains under review.
Geography
A representative national sample has not been established for this year.
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

    0.822 €

    Wrapped-gyro estimate 280 GRD, range 200-360. The range is a model assumption, not a confidence interval. Earlier extrapolation arguments were: from below, the 1989 free-market price (75 GRD) carried forward with the catering CPI (about 207-260 GRD); from above, the 2001 euro-campaign indicative price (399 GRD) deflated back to 1998 (about 365 GRD). That value lies outside the stated range and the campaign date remains under review.

  3. 3. Period price in the series

    0.822 €

    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.
