Part-month pay is also called pro rata or prorated starter and leaver pay. It covers one incomplete pay period, rather than a permanent part-time working pattern.
Calculate starter or leaver payCalendar-day estimate for one incomplete pay period.
Gross estimate before Income Tax, National Insurance and workplace pension deductions. Your contract and payroll policy take priority.
How part-month pay is estimated
For the calendar-day method, divide your normal pay for the period by the calendar days in that period, then multiply by the days you were employed. Employers may use a different contractual method, so compare the result with your contract or payroll policy.
Starter and leaver pay
A starter calculation counts from the employment start date to the period end. A leaver calculation counts from the period start through the final employment date. Both dates are included.
Example
On a £35,000 annual salary, normal monthly gross pay is £2,916.67. Working 15 days in a 30-day month gives an estimated £1,458.33 gross pay.
