Average Cash Earnings YoY

Average Cash Earnings YoY tracks the yearly change in average monthly total cash earnings (all employer-paid cash pay before tax) per regular employee. It comes from the Monthly Labour Survey (MHLW's monthly payroll survey) covering private and public workplaces with 5 or more regular employees across 16 industries. The sample (about 33,000 workplaces drawn from about 2,000,000) includes full-time (general) and part-time workers, with large workplaces (500 or more staff) fully counted. It is a macro average (total payroll divided by headcount), not any worker's raise and not household income, since it excludes retirement and investment income.

Payrolls are collected as of month-end (or the last payroll cutoff), with preliminary release about 5 weeks after month-end and final about 3 weeks later. Both releases (preliminary is initial tally, final is updated tally) appear at 08:30 Japan Standard Time; January shifts from pre-rotation to post-rotation workplaces at final. Each release brings cash, hours and employment tables plus time-series, appendix and same-firm references, with details on e-Stat (government data portal). Final adds late returns, with large shifts when late patterns differ, while base-year (reference year), benchmark (worker count) and seasonal yearly updates revise history.

Yearly pay moves with base pay, overtime, bonuses and workforce mix, since the headline is a straight sum with no fixed shares.

• Contractual cash earnings: preset pay set by contract or work rules, including base salaries, allowances and overtime, forming the recurring part.
• Scheduled cash earnings: contractual pay excluding overtime, mainly base salaries, where across-the-board pay-table lifts show most.
• Overtime pay: pay for hours beyond schedule, holidays and night work, tracking hours swings.
• Special payments: bonuses, long-period allowances and retroactive extras paid in the month, driving summer and winter spikes.
• Part-time share: shifts between full-time and part-time workers move the average even when no pay scale changes.

The June 2024 final (published August 23, 2024) put average monthly total pay at ¥498,887, up 4.5% from a year earlier. Contractual pay rose 2.1% while special payments jumped 7.8% on summer bonuses, so bonuses led the headline. General workers rose 5.0% and part-timers 5.7%.

Real (inflation-adjusted) total pay rose 1.1% while real contractual pay fell 1.2%, showing the consumer price gauge can split cash and real reads. Final revised several parts, 2024 growth used special 2023 references after a worker-count update, while same-workplace (same firms) growth hit 5.1%.

1. Sample expansion: each panel's payroll and headcount scale up by the inverse sampling ratio (grossing factor) to estimate economy-wide totals.
2. Per-worker average: estimated total cash payroll divided by estimated headcount gives average monthly yen per worker.
3. Nominal index: monthly yen divided by the base value times 100, with average of 2020 set to 100.
4. Nominal growth: divide the given month's index by the same month last year's index, subtract 1 and multiply by 100. For example, an index of 112.0 against 107.2 a year earlier gives about 4.5%. Published rates come from indices, so they can differ from math on rounded yen levels.
5. Real index: divide the nominal index by consumer prices and multiply by 100, using all items excluding imputed rent (notional homeowner rent). Real growth applies the same index-ratio formula to real indices.
6. Seasonal adjustment: calendar effects are removed with X-12-ARIMA (a census seasonal method); yearly change uses raw indices while monthly change uses adjusted indices. Yearly yen averages weight months by headcount; yearly index averages are simple 12-month means.
7. Illustrative example: with 400 workers sharing ¥120,000,000, average pay is ¥300,000; an α% pay-table lift with steady mix lifts the average by α%. If only seniority raises reshuffle the same payroll, the average stays ¥300,000 and growth is 0%.
