How it works

required hours = contracted hours per week × weeks in the period · period change = hours worked − required hours · closing balance = opening balance + period change (positive = credit, negative = time owed)

Under flexitime you can vary your daily hours as long as you meet a contracted total over a settlement period. The balance is simply how far ahead or behind that target you are: multiply your contracted weekly hours by the number of weeks to get the hours required, subtract that from the hours you actually worked, then add whatever balance you carried in. A positive closing balance is flex credit you can take as time off; a negative one is time you still owe. Many schemes cap how much credit or debit you may carry between periods.

Worked example

Contracted at 37.5 hours a week over 4 weeks, you are required to work 150 hours. You actually worked 158, a surplus of 8 hours this period. Starting from a zero opening balance, you close +8.00 hours in credit — nearly a full flexi-day banked.

Frequently asked questions

What does a negative balance mean?

It means you have worked fewer hours than required and owe that time — a flex debit. You clear it by working extra hours in a later period, and most schemes limit how large a debit you may carry forward.

How do I count part-weeks?

Enter the weeks as a decimal. A 4-week-and-3-day period at a 5-day week is about 4.6 weeks; or work out the exact required hours another way and back-calculate. The required total is just contracted hours × weeks.

Does this include overtime pay?

No — flexitime tracks hours, not pay. Surplus hours are normally taken back as time off rather than paid. If your extra hours are paid overtime instead, use an overtime pay calculator.
