A pay period is the recurring cycle of time for which an employer calculates and pays wages or salary. The most common types in the US are weekly (52 pay cheques/year), bi-weekly (26 pay cheques/year), semi-monthly (24 pay cheques/year), and monthly (12 pay cheques/year). Bi-weekly and semi-monthly are often confused: bi-weekly means every two weeks; semi-monthly means twice a calendar month (e.g., the 1st and 15th).
Pay period choice does not affect total annual income - only how and when that income is distributed. A $62,400 annual salary pays out as $1,200/week, $2,400 bi-weekly, $2,600 semi-monthly, or $5,200/month. Bi-weekly workers receive two "extra" pay cheques per year compared to semi-monthly workers, which can help with budgeting for irregular expenses.
When to use Pay Period
Use pay period when converting between hourly and annual income, calculating payroll costs, or comparing job offers that quote salary on different schedules. Always confirm which type a new employer uses - bi-weekly and semi-monthly pay produce different per-cheque amounts even at the same annual salary.
Worked examples for Pay Period
This table quickly gives you the overview you need to understand Pay Period and its most important comparisons.
| Pay Period | Cheques/Year | $62,400 annual salary |
|---|---|---|
| Weekly | 52 | $1,200 per week |
| Bi-weekly | 26 | $2,400 every 2 weeks |
| Semi-monthly | 24 | $2,600 twice a month |
| Monthly | 12 | $5,200 per month |
Common pitfalls
The most common mistake is treating bi-weekly and semi-monthly as the same. Multiplying a bi-weekly pay cheque by 24 (instead of 26) underestimates annual income by 7.7%. Always multiply bi-weekly pay by 26 and semi-monthly pay by 24 to get an accurate annual figure.
