Prorated Salary Calculator

A prorated salary is what you actually get paid when you work only part of a pay period. Start a job on the tenth, leave on the twentieth, or take a stretch of unpaid days, and your paycheck for that period is scaled down to match the days you were on the clock. The method is a simple proportion: take the pay you would earn for the whole period, then multiply by the fraction of the period you worked.

The one decision that matters is which days you count. Two conventions are common. The calendar-day method divides by every day in the period, weekends included, and is typical for salaried roles quoted as an annual figure. The workday method divides only by the working days, usually the weekdays, and tends to match how hourly-leaning employers think. They give slightly different answers for the same start date, so use whichever your employer states in the offer letter or handbook. If you are not sure, the calendar method is the more common default for annual salaries.

This calculator starts from your annual salary, splits it into the pay period you are actually paid on, weekly, every two weeks, twice a month, or monthly, and then prorates that single period. It shows the full-period pay for reference, the daily rate it derived, the prorated amount you should see on the check, and the portion you did not earn. The daily rate is the useful number to keep, because once you know what a single day is worth you can sanity-check any prorated figure your payroll department sends.

Enter your annual salary, choose the pay schedule, and fill in the total days in the period along with the days you worked. The result splits the full period into the part you earned and the part you did not.
