Four-weekly payday calculator

Four-weekly means every 28 days

Four-weekly pay follows a fixed 28-day cycle from your last payday. Like fortnightly pay, it's measured in days rather than tied to the calendar, so the date it lands on gradually shifts earlier through the month before resetting.

13 payments a year, not 12

A year has roughly 365.25 days. Divide that by 28 and you get around 13.04 — so four-weekly pay generally produces 13 payments across a full year, not 12 as with monthly pay. This is a well-known feature of four-weekly pay cycles, though the exact number of payments in any given 12-month period can vary slightly depending on where your pay dates fall.

Employment arrangements vary, and how your employer structures salary, tax deductions or budgeting around a 13-payment year is a matter for your contract and payroll department, not something this calculator determines. If you're unsure how your pay cycle is structured, check with your employer.

Four-weekly vs fortnightly and monthly

Four-weekly pay is sometimes confused with both fortnightly and monthly pay. It's not the same as fortnightly pay (every 14 days, 26 payments a year), and it's not the same as monthly pay (once a calendar month, 12 payments a year). If you're not sure which applies to you, check a recent payslip — the interval between two consecutive pay dates will tell you.
