How to use the Salary calculator

What this calculator does
The engine converts the entered amount to an annual amount using 52 weeks, 24 semi-monthly periods, 12 months, 4 quarters, or the relevant frequency.
Formula and method
The engine converts the entered amount to an annual amount using 52 weeks, 24 semi-monthly periods, 12 months, 4 quarters, or the relevant frequency. Hourly pay uses hoursPerWeek; daily pay uses a fixed five-day workweek in the conversion. An adjusted annual amount multiplies the annual figure by (daysPerWeek x 52 - holidays - vacation) / (daysPerWeek x 52), then converts that amount back to each display frequency.
Variables and inputs
Enter a salary amount, its frequency from hourly through yearly, hours per week, days per week, holidays per year, and vacation days per year. Currency fields are dollars; hours and days are work units; the last four inputs determine the adjusted comparison.
Worked example
For $104,000 per year, 40 hours per week, 5 days per week, 10 holidays, and 15 vacation days, unadjusted hourly pay is 104000 / (40 x 52) = $50.00. Paid workdays are 5 x 52 - 10 - 15 = 235, so adjusted annual pay is 104000 x 235 / 260 = $94,000 and adjusted hourly equivalent is $45.19.
How to interpret the result
Unadjusted values translate the stated pay frequency under the engine's calendar assumptions. Adjusted values show the same annual pay spread over the reduced workday count after entered holidays and vacation. They are comparison figures, not a payroll withholding calculation.
Common mistakes to avoid
Choose the frequency that matches the amount you entered. Do not enter annual salary in the hourly field. Check the workweek assumptions when comparing an offer with paid holidays, unpaid leave, overtime, bonuses, or a different number of paid weeks.
Assumptions and limitations
The route uses 52 weeks and assumes five days for daily conversions even though daysPerWeek affects the adjusted calculation. It does not calculate taxes, benefits, overtime, bonuses, commissions, unpaid leave, or employer retirement contributions.
