About Leave Accrual Calculator

Leave accrues pro rata through the leave year, so the balance available at any point is accrued entitlement plus carry-forward less days taken. Taking more than accrued creates a negative balance that is recovered from final pay if employment ends.

Formulas

Accrued to date

Accrued = Annual entitlement x Months worked / 12

Available

Available = Accrued + Carry forward - Days taken

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Can I take leave before it accrues?

Many employers allow it within the leave year, but the excess is recoverable from final pay on leaving. Statutory minima cannot be taken away retrospectively.

Does carry-forward always expire?

Usually there is a cap and a use-by date. Statutory leave often cannot be carried at all except where sickness or family leave prevented it being taken.
