Formula
How the calculation works
Unpaid leave is charged at the daily rate, and the daily rate is the monthly salary divided by the working days in that month, not by the calendar days. At 36,000 over 22 working days the day is 1,636, so five days cost 8,182 and leave 27,818.
The choice of divisor changes the cost noticeably. Divided by 22 working days the day costs more than divided by 30 calendar days, so the same five days away cost more in the first case. Employers use the working-day basis when the salary is meant to cover working days only, and that is the more common arrangement for a monthly salaried post.
Notice that the result is rarely a round number. 36,000 divided by 22 is not exact, so the deduction carries a fraction and the net pay does too. Rounding each figure to whole currency before subtracting would make the two disagree by a unit or two, which is why the rounding happens at display only.
Common mistakes
- Dividing by calendar days when the employer counts working days, which understates the cost of the leave.
- Subtracting the deduction from a monthly figure that already had tax removed, mixing gross and net.
- Assuming the deduction equals the unpaid days multiplied by the salary divided by 30 regardless of the month's actual working days.
When to use it
- Use it to see the real cost of unpaid days before agreeing to them, and to check that a payslip deduction matches the day rate you expect.
- It handles unpaid days only. Statutory sick pay, part-paid leave and unpaid overtime are different arrangements and this will not model them.
Worked example
At 36,000 over 22 working days, five unpaid days cost 8,182 and leave 27,818.
Common questions
Does normal leave get deducted?
No. This covers unpaid leave only. Paid leave is not deducted from salary, so leave those days out.
