Start with the work question, then choose the tool.

For paycheck questions, first decide whether the user needs gross pay, take-home pay, or a pay-period conversion. Gross pay answers wage math; paycheck calculators estimate net pay; pay-period tools compare weekly, biweekly, semimonthly, and monthly income.

For PTO questions, convert the time off into hours first, then compare it with the available or projected balance. Holidays, partial days, compressed schedules, and accrual timing should stay visible because they often change the final request.

For time-card questions, calculate paid time from actual clock-in, clock-out, and unpaid break minutes. Use a weekly time card for several shifts, a lunch-break calculator when meals vary, and decimal hours when the result must be entered into payroll or a spreadsheet.

For business-day questions, identify the start date, decide whether that date counts, then skip weekends and any listed holidays or closures. Do not use a business-day answer when the rule says calendar days.
