Market-neutral work and pay guide

How to use the Seasonal Job Annualization calculator

Compare seasonal earnings, the paid-season weekly run rate and a clearly labelled annualized comparison.

Five seasonal-pay measures answer different questions

Do not collapse actual earnings into the comparison run rate
MeasureMeaningUse
Seasonal earningsActual entered pay for the seasonAnchor the cash actually earned
Paid-season weekly run rateSeasonal earnings divided by paid weeksCompare the pace during paid work
Comparison run rateWeekly rate multiplied by comparison weeksHypothetical year-round comparison only
Calendar monthly averageActual seasonal earnings divided by 12Spread actual cash across the calendar
Off-season weeksComparison weeks less paid weeksMake the unpaid seasonal gap visible

Worked example: 24 paid weeks inside a 52-week comparison

Calendar monthly average24,000 ÷ 122,000 per month
Off-season time52 − 2428 weeks

Changing paid weeks changes pace, not actual earnings

Hold actual seasonal earnings at 24,000 and change only paid season weeks. A shorter season produces a higher weekly pace and hypothetical run rate, but the entered 24,000 of actual cash remains unchanged.

Budget from timing, not the headline run rate

  • Confirm actual payment dates and paid season weeks.
  • Keep off-season income separate rather than assuming the seasonal rate continues.
  • Map recurring costs against the calendar monthly average and cash timing.
  • Verify taxes, benefits and income-support rules separately for the relevant market.
