Work out night shift allowance instantly with clear inputs, formula shown and shareable results.
A night premium is a percentage uplift applied only to hours inside the defined night window. At 16 an hour with a 25% premium, each night hour earns an extra 4.00, so a six-hour night portion adds 24.00 per shift and 288.00 a month across twelve shifts. The enhanced rate of 20.00 is what appears on the payslip for those hours.
Premium per hour
premium = base rate x percentage / 100
Monthly allowance
allowance = night hours x premium x shifts
Usually 22:00 to 06:00 under working time regulations, but the paid window is set by contract and can differ.
Normally only on hours inside the night window, so an evening shift ending at 23:00 earns premium for one hour.
