Paid every 4 weeks vs monthly
Paid every 4 weeks means 13 paydays a year instead of 12. Your yearly pay is the same, but each payday is a little smaller than a monthly salary, your payday moves earlier each month, and one month gets two paydays. Use the calculator below to see your monthly equivalent and which month has two.
Four-weekly pay calculator
Quick maths: monthly equivalent = one four-weekly payday × 13 ÷ 12. Going the other way, a monthly salary × 12 ÷ 13 gives the same yearly pay paid every four weeks.

About 9.3% of employee jobs are paid every four weeks (ONS ASHE, April 2021).
Paid every 4 weeks vs monthly: the difference
| Every 4 weeks | Monthly | |
|---|---|---|
| Paydays a year | 13 | 12 |
| Payday date | Moves earlier each month | Same date each month |
| Gap between paydays | Always 28 days | 28 to 31 days |
| Each payday | Smaller (yearly ÷ 13) | Larger (yearly ÷ 12) |
| A month with two paydays | Yes, once a year | No |
Neither is better on pay: the yearly total is the same. Four-weekly pay is easier in short months and harder when monthly bills don't line up with your payday.
How four-weekly pay works
There are 52 weeks in a year, and 52 ÷ 4 = 13. Each payday is exactly 28 days after the last, so it lands on a different date each month and slowly drifts earlier through the year.
The month with two paydays
Once a year, two paydays land in the same calendar month. It feels like a bonus, but your monthly bills don't change. Many people set the second payday aside to cover the months where rent and bills come out before pay arrives.
Why monthly bills are awkward on four-weekly pay
Rent, council tax and most direct debits come out monthly, but your pay arrives every 28 days. Some pay periods cover two rent payments, others cover one. Seeing your balance for every day ahead shows which pay periods will be tight.
Benefits paid every 4 weeks
PIP is usually paid every four weeks, and Carer's Allowance weekly or every four weeks (DWP benefits statistics, August 2025). The same 13-payment pattern applies.
