Hourly vs salary on a paycheck

A $72,000 salary and $34.62 an hour at 40 hours are the same annual gross in a 52-week model. The checks still diverge as soon as hours move, overtime appears, or the employer uses a different period count.

Hours are a tax input

Missed hours lower this period’s FICA and income-tax withholding. Overtime raises both. Because withholding annualizes the current check, a 50-hour week can withhold as if you will work 50-hour weeks all year. Your April return uses actual annual wages, not that fiction.

Frequency changes the slice, not the rate

Weekly, biweekly, and semimonthly are not the same. 26 biweekly checks are not 24 semimonthly checks. Two “extra” checks a year are usually just the 26-period calendar, not a bonus. PayNetUS lets you pick the period so the per-check net is divided consistently.

Salary is not immune

Exempt salaried staff still see FICA and income tax. A mid-year raise, unpaid leave, or a lump-sum payout will swing withholding the same way overtime does for hourly staff.

Use the calculator in hourly mode (rate × hours × 52) or salary mode, then toggle frequency. Overtime multipliers are not modeled — add them into hours or salary if you want a rougher check.
