Prorated Salary Calculator
Work out gross pay for a partial pay period after a mid-cycle start, exit, unpaid leave, or raise. Prorate by calendar days, working days, or hours.
Prorated Salary Calculator
Salary and schedule
Gross salary before any deductions.
Biweekly (26 checks) and semi-monthly (24 checks) are different schedules. Getting this wrong moves the per-period gross by about 8%.
Proration method
Calendar days counts weekends, working days counts business days only, hours uses the scheduled hours in the period. Working days is the method most US payroll guidance recommends.
Period and days worked
Average figure. A real semi-monthly period is 13 to 16 calendar days and 10 to 12 working days. Enter the actual count for the period you are paying, or use the date helper below.
Paid days only. Subtract any unpaid company holidays or unpaid leave yourself if your policy excludes them.
Work dates are clamped to the pay period on both sides, so someone hired and separated inside one cycle is counted correctly. All counts include both endpoints.
Used to turn the weekday count into scheduled hours.
Mid-period rate change
For a raise, demotion, or promotion that lands inside one pay period. Both rates divide by the same number of days in the period.
The remaining days worked are paid at the old rate.
Enter a salary amount above to see a prorated figure.
Enter how many days (or hours) are in the full pay period.
No paid days in this period. An exempt employee owes no salary for a workweek in which no work is performed at all.
Days at the new rate cannot exceed total days worked. The old-rate segment is held at zero.
Gross pay only. Prorated wages are taxed like any other wages, so take the figure above into the FICA tax calculator for the withholding side.

How to calculate a prorated salary
Proration is two divisions and a multiplication. Nothing about it is clever, but every step is somewhere to slip a decimal, which is why the calculator prints the intermediate figures instead of just the answer.
- Full-period gross = annual salary divided by the pay periods in a year (52 weekly, 26 biweekly, 24 semi-monthly, 12 monthly)
- Unit rate = full-period gross divided by the days (or hours) in that period
- Prorated gross = unit rate times the days actually worked
Here it is with real numbers. A salaried employee on $60,000 paid semi-monthly earns $60,000 divided by 24, or $2,500 per period. The period being paid runs the 1st through the 15th and holds 11 working days, so the daily rate is $2,500 divided by 11, or $227.2727. The employee started on the 4th and worked 8 of those days, so gross pay is $227.2727 times 8, or $1,818.18. The $681.82 left over is the rest of the period.
Same answer the other way round: the employee worked 8 of 11 days, and 8 divided by 11 of $2,500 is $1,818.18 again. Multiply by the fraction itself, not by the rounded 72.7% the panel displays, or you land $0.68 short. Use whichever version the person checking your work finds easier to follow.
The same chain runs on every schedule. Weekly: $60,000 divided by 52 is $1,153.85, divided by 5 working days is $230.7692 a day, times 3 days is $692.31. Biweekly: $60,000 divided by 26 is $2,307.69, divided by 10 working days is $230.7692 a day, times 6 days is $1,384.62. Monthly: $60,000 divided by 12 is $5,000, divided by 22 working days in that month is $227.2727 a day, times 14 days is $3,181.82. The daily rate barely moves across schedules, because underneath it is just annual salary divided by working days in the year. If you need the per-period figure on its own, the pay frequency converter does that first step.
One rounding rule matters: do not round the daily rate before you multiply. $227.27 times 8 is $1,818.16, two cents short of the correct $1,818.18. That is why the rate above shows four decimal places, and why the calculator holds the arithmetic in cents until the moment it prints.
Calendar days, working days, or hours: which method to use
The divisor is the whole argument. There are three defensible choices, and they produce different money.
- Calendar days counts every day in the period, weekends included, roughly 365 a year. Simplest to explain, and it produces the lowest daily rate.
- Working days counts business days only, roughly 260 a year. It is the default here because it is the method most US payroll guidance walks through, and it does not punish someone for starting on a Wednesday.
- Hours divides by scheduled hours, 2,080 a year for a standard full-time schedule. It lines up with the FLSA's own phrasing about the hourly or daily equivalent of an employee's full salary, which makes it the easiest of the three to defend in a dispute.
Price the same scenario three ways to see the spread. An employee on $60,000 paid semi-monthly, working the last 8 working days of a period that runs the 1st to the 15th (11 working days, 15 calendar days, 88 scheduled hours). Working days: $2,500 divided by 11 is $227.2727 a day, times 8 is $1,818.18. Calendar days: the 8 working days span 12 calendar days, so $2,500 divided by 15 is $166.6667 a day, times 12 is $2,000.00. Hours: $2,500 divided by 88 is $28.4091 an hour, times 64 hours is $1,818.18. The hourly and working-day methods agree, as they should, since both exclude weekends. Calendar-day proration lands $181.82 higher here because it pays the intervening weekend.
Pick by policy, not by employee. Check the offer letter and the handbook first, because a written method binds you. If nothing is written down, use working days and apply it to everybody. Switching methods case by case is how a proration turns into a wage claim.
When salary gets prorated: new hires, final checks, unpaid leave, and raises
A new hire starting mid-period. Count from the first day worked through the end of the period and apply the daily rate. This is the cleanest case, and 29 CFR 541.602(b)(6) expressly permits a proportionate part of the salary for time actually worked in the first week of employment.
A separation mid-period. Same rule at the other end of the period, and the same regulation covers the last week of employment. The prorated figure is usually one line in a final check that also carries unused PTO, an overtime true-up, or severance. The final paycheck calculator assembles the rest of that check.
Hired and separated inside one period. A temp or a seasonal hire can start and end inside a single cycle. The date helper clamps the work dates to the pay period on both sides, so the count comes out right without any hand arithmetic.
Unpaid leave. Tread carefully here. The FLSA salary-basis rule generally requires an exempt employee's full weekly salary for any week in which any work is performed, and the permitted deductions are a short, specific list. No salary is owed for a workweek in which no work is performed at all. Prorating a mid-employment unpaid day is not the same free hand you have in the first and last week, so confirm the deduction is allowed before you run the number.
A raise landing mid-period. This is one period paid at two rates, not two periods. Pay the old rate for the days before the increase and the new rate for the days after, dividing both by the same number of days in the period. On $60,000 going to $66,000 semi-monthly with 11 working days, the old daily rate is $227.2727 and the new one is $250.00, so 5 days old plus 6 days new is $1,136.36 plus $1,500.00, or $2,636.36 for the period. Turn on "Rate changed mid-period" above to run yours.
Every one of these breaks the even run rate in your year-to-date column, which is worth reconciling before the next stub goes out. The YTD earnings calculator is where that gets straightened out, and if the hourly method left you holding an hourly equivalent, the hourly to paystub earnings calculator turns it into actual earnings lines.
Putting the prorated amount on an actual pay stub
A prorated amount is not a pay stub. It is one earning line on one, and it has to sit beside the hours and rate that produced it, the deductions that came out of it, employer contributions, and a year-to-date column that still adds up after a short period.
That is the part Payslip44 handles. Employers, employees, and line items save as reusable templates, so the second prorated check takes seconds instead of a rebuild. Classifications cover W-2, 1099, statutory, and owner. Money math runs on Decimal, so a rate like $227.2727 multiplied across a period does not drift a cent. There are six layouts, everything runs on device, and finished stubs export as PDF, PNG, CSV, or plain text.

Frequently Asked Questions
Common questions about prorated salary calculator
How do you calculate a prorated salary?
Divide the annual salary by the number of pay periods in a year to get full-period gross, divide that by the number of days (or hours) in the period to get the daily or hourly rate, then multiply by the days actually worked. Example: $60,000 divided by 24 semi-monthly periods is $2,500; $2,500 divided by 11 working days is $227.2727 a day; times 8 days worked is $1,818.18.
How is pay prorated for a mid-month start date?
Count only the days from the start date through the end of the pay period, then apply the daily rate. If the period runs the 1st through the 15th and the employee starts on the 8th, they are paid for the days from the 8th onward, not the whole half-month. Turn on the date helper above and it counts those days for you, weekdays included or excluded depending on the method you picked.
What is the difference between calendar-day and working-day proration?
Calendar-day proration divides by every day in the period, weekends included, which works out to about 365 days a year. Working-day proration divides by business days only, about 260 a year. The working-day method produces a higher daily rate and is generally fairer to someone who starts mid-week. The calendar-day method is simpler to explain. Whichever one you pick, write it into your policy and use it for everybody.
Is it legal to prorate a salaried employee's pay?
For exempt employees the FLSA salary-basis rule generally requires the full weekly salary for any week in which any work is performed, but 29 CFR 541.602(b)(6) expressly allows a proportionate part of the salary for time actually worked in the first and last week of employment. No salary is owed for a workweek in which no work is performed at all. Unpaid leave in the middle of employment is far more restricted, so check the rule before you deduct.
How do you prorate pay for a mid-period raise?
Pay the old rate for the days before the increase and the new rate for the days after, dividing both rates by the same number of days in the period. It is one pay period paid at two rates, not two separate periods. Switch on "Rate changed mid-period" above and enter how many days fell at the new rate.
How many working days are in a semi-monthly pay period?
Usually 10 to 12, averaging about 10.83 (260 working days divided by 24 periods). Biweekly periods are always exactly 14 calendar days and 10 working days, but semi-monthly periods vary because the 1st through 15th and the 16th through end-of-month halves are different lengths. Use the date helper to count the period you are actually paying instead of trusting the average.
Do holidays and PTO count as days worked when prorating?
If the employee is entitled to the paid holiday, or has approved paid leave falling inside the period, those days are normally paid and count toward days worked. Unpaid days do not. Adjust the days-worked figure to match your policy, because the calculator does not guess at your holiday calendar.
Is prorated pay taxed differently?
No. Prorated wages are ordinary wages: the same income-tax withholding and the same Social Security and Medicare treatment apply, just on a smaller gross. This calculator shows gross only, so run the result through the FICA tax calculator to see the withholding side.
