Monday to Friday only, which is what most US employers use.
Days In This Period
Auto-filled from your pay frequency. Adjust to the actual count for your period: semimonthly periods run 10 to 12 workdays and monthly periods 20 to 23.
Half days are allowed (use 0.5 steps) for a start or end date that falls mid-day.
Days worked is calculated as days in the period minus the unpaid days you enter here.
The rest of your days worked are paid at the old salary. A raise splits the period into two paid segments, which is a different case from partial employment, where one salary covers only part of the period.
Gross pay only, before taxes and deductions. Estimates only, not tax or legal advice. Your employer's written policy or contract governs which method applies.
Mid-Period Raise Split
Work the whole period across both salaries and the two subtotals add up to one full paycheck at a blended rate.
Cross-Check: Annual-Divisor Method
Both methods are permitted under 29 C.F.R. 541.602(c) as long as an employer applies one consistently, so the two figures rarely match to the cent. Daily rates are displayed rounded to two decimals but the unrounded value feeds the total; payroll systems that round the daily rate first can land a few cents apart.
Check the check against your own record
A prorated paycheck is only right if the day count is right. ClockWage44 logs every shift across as many jobs as you work and resolves federal tax, state tax, FICA, overtime rules, and deductions into a to-the-cent take-home figure, all on-device.
How prorated salary is calculated
Proration is a two-step job. First find a daily rate, then multiply it by the days you actually worked. The daily rate is where every disagreement starts, because there is more than one legitimate way to get it.
The period-divisor method takes the gross for one full pay period and divides by the days in that specific period. On a $75,000 salary paid monthly, one period is $75,000 / 12 = $6,250. A month with 22 workdays gives a daily rate of $6,250 / 22 = $284.09, so 12 days worked is $3,409.09 gross.
The annual-divisor method skips the period and divides the annual salary by a fixed number of paid days: 260 workdays, or 365 calendar days. Same salary, same 12 days: $75,000 / 260 = $288.46 a day, and 12 days is $3,461.54. That is $52.45 more than the period-divisor answer, from identical inputs. Neither number is wrong, which is why the calculator shows both.
Days in a period vary more than people expect. A semimonthly period can hold 10, 11, or 12 workdays depending on where the weekends land, and a monthly period runs anywhere from 20 to 23. The count filled in above is a guess based on your pay frequency. Overwrite it with the real number from your payroll calendar.
Workdays vs calendar days: the choice that changes your check
On a $75,000 salary, a workday daily rate is $75,000 / 260 = $288.46. The calendar-day rate is $75,000 / 365 = $205.48. That gap is not rounding. The two methods disagree about what a single day of salary is worth.
US payroll practice leans heavily toward workdays. You were never scheduled to work weekends, so counting them dilutes the rate and can shortchange a partial period that happens to end on a Friday. Calendar-day proration shows up mostly where pay is treated as accruing continuously, such as some leave and severance arrangements, or where a contract says so.
The rule that matters more than either method: pick one and apply it to everybody. An employer that prorates one new hire on workdays and the next on calendar days invites a pay-equity problem. Your handbook or employment contract decides which one governs your check. The calendar option here uses a fixed 365, so if your period sits in a leap year and you need the exact figure, enter the actual calendar day count instead.
When your salary gets prorated
Five situations account for nearly all of it: starting mid-period, leaving mid-period (resignation or termination), taking unpaid leave, receiving a raise partway through a period, and changing scheduled hours (going from full time to part time, for instance).
For exempt salaried employees, the FLSA is specific about which of these allow a reduced check. Under 29 C.F.R. 541.602(b)(6), an employer may pay a proportionate part of the salary in the initial and terminal weeks of employment, which covers the start and departure cases. Full-day absences under a bona fide unpaid leave or PTO policy can also be deducted. What generally cannot be deducted is a partial day: docking an exempt employee for leaving three hours early puts the exemption itself at risk, and losing it can mean back overtime for the whole period. State wage law can be stricter than the federal floor.
A mid-period raise is a different animal. Nothing is taken away. The period splits into two segments, each paid at its own daily rate. Work every day of the period and the two subtotals should still add up to a full paycheck, just a blended one.
Check your prorated paycheck against the days you actually worked
Every figure here depends on one input nobody verifies: the number of days payroll thinks you worked. If that count is off by a day, the check is off by a daily rate, and a partial period is exactly when a miscount is easiest to miss.
ClockWage44 keeps that record on your side. It logs every shift across as many jobs as you want, then runs federal tax, state tax, FICA, overtime rules, and deductions into a to-the-cent take-home figure, all on-device. Hold a partial-period check up against your own log instead of trusting the number that showed up. Download the app to keep the count. These figures are estimates only, not tax or legal advice.
Frequently Asked Questions
Common questions about prorated salary calculator
How do you calculate a prorated salary?
Divide the pay for the full period by the number of workdays in that period to get a daily rate, then multiply by the days you actually worked. For a $75,000 salary paid monthly with 22 workdays in the month, the daily rate is $6,250 divided by 22, or $284.09, so 12 days worked comes to $3,409.09 in gross pay.
Should prorated pay use 260 workdays or 365 calendar days?
Workdays, in most US payroll practice. Dividing by 365 deflates the daily rate because you were never expected to work weekends, so a partial period ending on a Friday would shortchange you. The 260-workday figure is 52 weeks times 5 days; some employers use a slightly different number based on their holiday calendar or contract. The calendar option here uses a fixed 365, so a leap year (366 days) makes the real daily rate about 0.27% lower. If you need exact leap-year math, enter the actual calendar days for your period instead.
Is it legal for an employer to prorate a salaried employee's pay?
Yes, in the specific situations the FLSA allows. Under 29 C.F.R. 541.602(b)(6), an employer does not have to pay a full salary in the initial or terminal week of employment and may pay a proportionate part of the salary for time actually worked. Outside those windows, most partial-day deductions from an exempt employee's salary are prohibited and can jeopardize the exemption. State wage law can be stricter than the federal rule.
Which proration method is my employer allowed to use?
More than one. 29 C.F.R. 541.602(c) lets an employer use the hourly or daily equivalent of the full weekly salary, or any other amount proportional to the time actually missed. Courts have accepted both dividing the period's salary by the workdays in that period and dividing the annual salary by 52 weeks and then by workdays per week. What matters is that the method is proportional and applied consistently, which is why this calculator shows both figures side by side.
How do I prorate my salary if I started mid-month?
Count the workdays from your start date to the end of the pay period, then multiply by the daily rate for that period. Your first check is short; the next one is a normal full paycheck on the regular payday. The pay period calculator maps your period boundaries and paydays if you are not sure where the period ends.
How does a mid-period raise get prorated?
Payroll splits the period in two: days at the old salary times the old daily rate, plus days at the new salary times the new daily rate. Turn on "Salary changed mid-period" above to see both segments. The two subtotals together equal one full paycheck at a blended rate if you worked the whole period.
Does prorated pay change how much tax is withheld?
Withholding runs off the gross amount of the check, so a smaller prorated check usually has less tax taken out. The effective rate often drops too, because most withholding methods annualize the check as if every paycheck were that size. Your annual tax bill does not change; it evens out at filing. This tool shows gross pay only, so use the take-home pay calculator for the net figure.
How do unpaid days off affect a salaried paycheck?
Full unpaid days under a bona fide leave or PTO policy can be deducted from an exempt employee's salary; partial-day deductions generally cannot. Switch the "Enter" toggle to "Unpaid days missed" to calculate the reduced check.
What if my pay period has a different number of workdays than the default?
Overwrite the days-in-period field. Semimonthly periods often swing between 10 and 12 workdays, and monthly periods between 20 and 23, so the auto-filled number is only a starting point. Use the real count from your payroll calendar.
