Your pay rises, but groceries cost more too. Compare reference prices, the work time needed and two hypothetical paths: price inflation and money supply.
Your own shopping basket can change differently from the average statistical basket. This guide explains stated pay versus purchasing power, then helps you distinguish observed prices, approximate examples and calculated equivalents.
What a product from back then would cost today if it had followed the consumer price index published by that zone's statistics office, exactly.
What that same product would cost if it had followed money supply growth over the same period. The gap between the two columns is usually the most revealing part.
Next to the two calculated benchmarks, the price you actually pay today. Three figures, and the gap becomes readable at a glance.
Nominal pay is the amount on the payslip. Real pay describes what it can buy. If pay rises 2% while prices rise 4%, purchasing power falls about 1.9%: 1.02 ÷ 1.04 − 1.
The price index tracks a representative basket. If you spend heavily on rent or fuel, your personal change can differ. A national index is useful for comparing periods, but it does not replace your own budget.
The Big Mac is an observation from The Economist. US eggs per dozen and gasoline per gallon are BLS average prices. These series show a source and date. Other basket prices are approximate illustrations; they do not prove the actual change in a local price. Historical prices may be interpolated between reference points.
A €3 item at €12/hour gross pay represents 15 minutes: 3 ÷ 12 × 60. This is not the time needed to save €3 after tax, contributions and bills. Wage references cover specific areas: for example Ontario and Geneva, not all of Canada or Switzerland.
The price benchmark shows the amount needed to keep the same purchasing power against the average basket. The money benchmark shows the amount needed to keep the same slice of the money pie. For pay, it compares the amount paid with total money at that date, not the employee’s wealth. These equivalents are not promised wages, observed prices or two losses to add together.
