UK Holiday Pay Calculator — 2026
What your untaken holiday is worth when you leave a job: the gross payout at your daily rate, and what is left after income tax, National Insurance and any student loan repayment.
Days owed are the days accrued this leave year less the days taken.
How the holiday pay works
Days owed are the days accrued this leave year less the days taken. The daily rate is annual salary ÷ 52 ÷ working days a week, and the gross payout is days × rate. For irregular-hours and part-year workers the payout is 12.07% of the hours worked, at the hourly rate on a 37.5-hour week. Tax, NI and student loan are the extra amounts due when the payout is added on top of the salary already earned in the year.
Formula: Payout = (accrued − taken) × salary ÷ 52 ÷ working days · irregular: hours × 12.07% × salary ÷ (52 × 37.5) · tax = tax(salary + payout) − tax(salary), floored at the band rate
