How to calculate 100 hours holiday in shifts

Start with your holiday balance of 100 hours, then divide it by the number of paid hours in one normal shift.

For example, if your normal shift is 10 hours:

100 ÷ 10 = 10

So: 100 hours holiday = 10 × 10-hour shifts

If the result is not a whole number, it is usually clearer to show the answer as full shifts + remaining hours rather than only using a decimal number of shifts.

How many 7h30m shifts is 100 hours holiday?

A 7h30m paid shift is 7.5 hours.

13 × 7h30m = 97h30m, leaving 2h30m

So: 100 hours holiday = 13 full 7h30m shifts + 2h30m remaining

How many 8-hour shifts is 100 hours holiday?

12 × 8h = 96h, leaving 4h

So: 100 hours holiday = 12 full 8-hour shifts + 4 hours remaining

Mathematically, 100 ÷ 8 is 12.5 shifts, but for a holiday balance it is often more useful to show the result as full shifts plus the hours left over.

How many 10-hour shifts is 100 hours holiday?

This is one of the simplest conversions.

100 ÷ 10 = 10

So 100 hours holiday = 10 full 10-hour shifts, with no remaining balance.

How many 11h30m shifts is 100 hours holiday?

An 11h30m paid shift is 11.5 decimal hours.

8 × 11h30m = 92h, leaving 8h

So: 100 hours holiday = 8 full 11h30m shifts + 8 hours remaining

This is a good example of why showing the remaining hours can be more useful than only giving a decimal number of shifts.

How many 12-hour shifts is 100 hours holiday?

If your paid shift length is 12 hours:

8 × 12h = 96h, leaving 4h

So: 100 hours holiday = 8 full 12-hour shifts + 4 hours remaining

However, make sure that 12 hours is actually the paid length of the shift. A shift described as a “12-hour shift” may include an unpaid break.

How many days is 100 hours holiday?

100 hours is not a fixed number of days until you know how many paid hours make up one normal working day.

• 7h30m day → 13 full days + 2h30m
• 8h day → 12 full days + 4h
• 10h day → 10 days
• 12h day → 8 full days + 4h

So saying 100 hours = 12.5 days is only correct if one normal paid working day is exactly 8 hours.

Why paid shift length matters

The amount of time you are at work is not always the same as the number of paid hours in the shift.

• Start: 07:00
• Finish: 19:00
• Total time on site: 12h
• Unpaid break: 30m
• Paid shift: 11h30m

If taking the whole shift as annual leave uses 11h30m from your balance, that is the figure to use.

8 × 11h30m = 92h, leaving 8h

That is different from treating the shift as 12 paid hours, which would leave only 4 hours after eight shifts.

Use the amount of leave that would actually be deducted from your balance.

What if your shifts are different lengths?

If every shift is the same length, converting 100 hours into shifts is straightforward.

If your shifts vary, there may not be one fixed answer.

For example, an 8h shift on Monday, a 6h shift on Tuesday and a 10h shift on Thursday. Taking all three as annual leave would use:

8h + 6h + 10h = 24h

Starting from 100h, your remaining balance would be 76h.

For variable shifts, it is usually better to deduct each booked shift individually rather than divide the full balance by one standard shift length.

How does a 100-hour holiday balance reduce?

For someone working fixed 10-hour paid shifts:

• Starting balance: 100h
• After one shift: 90h
• After two shifts: 80h
• After three shifts: 70h
• After four shifts: 60h
• After five shifts: 50h
• After ten shifts: 0h
