Maternity Leave Holiday Carryover Calculator

Based on the default pattern below, a typical entitlement is 20 days. Adjust the inputs for your exact figure.

5 days

Your entitlement

20 days

How it's worked out

(5 days ÷ 5 full-time days) × 4 protected weeks × 5 days = 20 days

Audit note

This is the Reg 13 protected carryover for specific circumstances — long-term sickness, maternity, parental, shared parental or carer's leave — not a general right to carry over your core 4 weeks. It must be pro-rated for part-time and part-year patterns, and used within 18 months of the end of the leave year it accrued in.

Stop tracking this by hand

Carryover only stays accurate if the balance behind it is accurate. Tempry tracks every day of accrued, taken and carried-over leave automatically, so nobody has to work out a carryover cap or a forfeiture deadline by hand again.

How this calculation works

Long-term sick, maternity, parental, shared parental or carer's leave stopped you taking your holiday? UK law protects your core 4 weeks — carry it forward, pro-rated to your working pattern, instead of losing it.

Worked example

(5 days ÷ 5 full-time days) × 4 protected weeks × 5 days = 20 days

Frequently asked questions

Do I lose holiday I couldn't take while on maternity leave?
No — maternity leave is one of the protected reasons under Regulation 13, so up to 4 weeks of unused statutory leave carries into your next leave year instead of being forfeited.
Does holiday accrue during maternity leave?
Yes, in full — you accrue statutory (and any contractual) holiday throughout ordinary and additional maternity leave exactly as if you were at work.
Can my employer make me take annual leave during maternity leave?
No. Maternity leave and annual leave are separate; your employer can't require you to take holiday while you're on maternity leave, which is precisely why the carryover protection exists.
Would I get a different cap for a different protected reason?
No — maternity leave shares exactly the same 4-week Regulation 13 protected cap as long-term sickness, parental, shared parental and carer's leave. Only the eligibility circumstance differs; the pro-rated amount protected is identical.
