How to tell if you're paid biweekly or semimonthly

By Cooper Digital · Updated October 15, 2026 · 3 min read

You need to know your exact pay frequency before you can plan bills or 3-paycheck months. Here's how to check in under a minute.

Quick answerCount the days between your last two paydays. Always 14 days and the same weekday = biweekly. Fixed calendar dates (like the 15th and last day) with 13–17 days between = semimonthly.

Check 1: Your last three pay dates

Example datesDays apartFrequency
Fri Oct 9, Fri Oct 23, Fri Nov 614, 14Biweekly
Thu Oct 15, Fri Oct 30, Fri Nov 1315, 14Semimonthly (15th & last business day)
Fri Oct 9, Fri Oct 16, Fri Oct 237, 7Weekly

Check 2: Your pay stub

Look for "pay frequency," "pay period," or the period dates. A 14-day period (e.g. Sep 27 – Oct 10) is biweekly. A period ending on the 15th or the last day of the month is semimonthly. Hourly biweekly stubs usually show 80 regular hours.

Check 3: Your gross pay vs salary

Divide your salary by your gross pay per check. About 26 = biweekly; 24 = semimonthly. Example: $60,000 ÷ $2,307.69 = 26.

Signs you mixed them up

Once you know, write the frequency at the top of your budget. Everything else (bill timing, savings per check, 3-paycheck months) depends on it.
