Four-Weekly Pay vs Monthly Pay: 13 Pay Periods and Overtime Math

The Short Answer

Four-weekly pay means a payday every four weeks, or every 28 days. It normally produces 13 pay periods across a 52-week cycle. Monthly pay normally produces 12. These are different schedules even though people sometimes call both a monthly paycheck.

For a salary allocated over 13 equal periods, annual salary ÷ 13 gives the gross four-weekly amount. For steady hourly work, calculate each week's wages and add the four weeks. Neither formula estimates take-home pay without considering deductions.

A $52,000 Salary on Different Pay Schedules

Assume an annual salary of $52,000 and equal installments under the employer's payroll arrangement:

• Weekly, using 52 installments: $1,000.
• Every two weeks, using 26 installments: $2,000.
• Every four weeks, using 13 installments: $4,000.
• Monthly, using 12 installments: about $4,333.33, with rounding reconciled by payroll.

The smaller four-weekly check is not necessarily a pay cut. Thirteen $4,000 installments still total $52,000. Twelve $4,000 checks would total only $48,000, so treating a four-weekly amount as a monthly amount understates annual pay.

Conversely, $3,000 per four-week period represents $39,000 over 13 periods, not $36,000. Check whether an offer quotes annual, monthly or four-weekly pay before comparing jobs.

Why Payday Moves Through the Month

A 28-day schedule usually retains the same weekday but shifts to different dates within the month. Monthly rent and loan payments do not move with it. Build a payday calendar from your employer's actual dates rather than assigning every deposit to the first of the month.

Thirteen periods cover 364 days. A calendar year has 365 or 366, so the number of deposits within a specific calendar year can depend on the first payday and schedule; occasionally there can be 14. Do not assume an extra deposit is automatically extra annual salary. Ask payroll how the annual salary, pay periods and year-end alignment are handled.

Hourly Workers: Add Four Weekly Calculations

For a covered, non-exempt U.S. worker, a four-week paycheck does not create a 160-hour overtime threshold. Under the ordinary FLSA rule, overtime is calculated separately for each workweek.

Consider $20 an hour with no bonuses or differentials, and weekly hours of 50, 30, 40 and 40:

• Week 1: 40 × $20 + 10 × $30 = $1,100.
• Week 2: 30 × $20 = $600.
• Week 3: 40 × $20 = $800.
• Week 4: 40 × $20 = $800.
• Four-week gross total: $3,300.

Multiplying the combined 160 hours by $20 gives $3,200 and misses $100 of overtime premium. The quiet week does not cancel the busy week's overtime. State daily rules may require an additional calculation before you total the weeks.

Budgeting Without Confusing Gross and Net

For a stable 13-period arrangement, convert a four-week gross amount into an average monthly figure with four-week pay × 13 ÷ 12. A $4,000 amount corresponds to about $4,333.33 per average month, but that is not what necessarily lands in your bank account during any particular month.

Use actual net deposits and payday dates for bills. Benefit deductions, tax withholding, unpaid time and overtime can change individual deposits. An average is a planning tool, not a promised check.

Frequently Asked Questions

Is four-weekly pay the same as twice a month?

No. Twice-monthly pay normally means 24 installments annually. Four-weekly pay means 28-day spacing and normally 13 periods in a 52-week cycle.

Can my employer average overtime over four weeks?

Not under the ordinary federal workweek rule. Specific statutory arrangements exist for certain workers, but a payroll frequency alone does not authorize averaging.

Which calculator should I use?

Use the weekly pay calculator for each week and total the four results. The monthly salary calculator is useful for average monthly comparisons, not for predicting a 28-day payday.
