Formula and method

At 20 per hour, eight hours/day and five days/week, gross yearly pay is 41600. With 20 unpaid days it falls to 38400.

Annual hourly pay = rate × hours/day × days/week × 52; adjustment = 1 − (holiday + vacation days)/(52 days/week).

Assumptions and limitations

  • Uses exactly 52 workweeks per year. Holiday and vacation days are treated as unpaid for the adjusted column; actual contracts may pay those days.
  • Weekly, fortnightly and monthly source modes treat entered pay as the adjusted amount and infer the full amount by dividing by the adjustment factor. Hourly and daily modes treat entered pay as full pay.
  • This is gross arithmetic before tax, benefits and payroll deductions.
  • Enter all monetary amounts in a single currency. Retained currency conversion factors are a captured static snapshot, not live exchange rates.
  • Clear a known field before solving for it. Locks retain chosen inputs; inconsistent locked values need correction. Reset restores the captured defaults.
