Index calculations
Every intermediate step of the index per year: gross wage, contributions, net wage, gyro price, rounding and the final quotient, plus a unit guard and a detailed description of every special case (price regulation, Athens premium, classic-equivalent rescaling, drachma-euro transition).
Unit guard before the calculation
Before every division we verify that the net wage is in euros per month (EUR 10-3000) and the gyro price in euros per item (EUR 0.005-25), ruling out drachma/euro or cent mix-ups.
51/51 years pass the unit guard
The statutory minimum wage per year
The table reproduces the series gross wage and deduction/payment assumptions. Original drachma inputs are preserved; other drachma displays are conversions from euros. A source reference does not certify a complete annual payroll calendar. Formula: net per payment = gross × (1 − deductions); monthly annual equivalent = net per payment × payments / 12.

The table shows the twelve-month mean gross wage and the selected contributions for the common profile. Old one-date values are retained only in the research audit, and grade-B cells remain visible. Income tax is not deducted here. The separate scenario applies scales to 39 years from 1988, producing positive tax in 14 years under its assumptions. This does not certify an individual payslip or actual annual tax liability.
Annualisation used by the model
One annualisation rule compares full-year income on a common twelve-month basis. It is an index convention, not an individual payslip.
- 1976-202614 payments (x1.1667) - One conventional annualisation including bonuses and a full holiday allowance. It is not an individual payslip; lower-grade evidence cells remain separately identified.

Minimum wage after employee contributions, before income tax. From 1976 and throughout the series it is the mean of the year’s twelve months, using each month’s minimum and contribution rate. Fourteen payments are annualised and divided by twelve. Lower-grade evidence cells in the early period remain separately identified. This is not the mean or median wage of employees.

Monthly equivalent = gross × (1 − deductions) × 14 / 12, rounded to cents only at the end. Gross and deductions are twelve-month means. Drachma conversion and the intermediate amount retain full precision. Income tax is not deducted. Lower-grade early evidence cells remain identified. The period price follows the series precision. Index = round(monthly equivalent ÷ selected price). The ‘from rounding’ label identifies a difference from the quotient before intermediate rounding. Equivalence = 0.7 × min(grams / 88, 1.35) + 0.3 × (0.65 + 0.35 × fries share). Equivalence, its reciprocal factor and the classic price are successively rounded to 3 decimals. The wage is divided by that price and the quotient rounded to an integer. 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.
Sensitivity analysis: how much does the assumption matter?
Move the three rescaling assumptions and watch how each era's index responds. This is a what-if: the published index figures do not change.

Under the current assumptions the peak lands in 1985 at 504 classic gyros/month. The conclusion "today's purchasing power is below the peak" survives across the whole 40-90% meat-share range - the size of the drop does not.
The base year changes the unit, not the finding: across each of the 28 base years that never trigger the cap, the drop from 2011 to 2026 stays between 48.2% and 48.7%.
