Enter salary and date ranges to see prorated pay.

How it works

The calculator divides your annual salary by the number of pay periods per year to get base pay for one full period. It then multiplies that amount by the share of the period you actually worked, using inclusive calendar days on the UTC calendar.

Partial-period days must fall within the full pay period you define. If you start mid-month, set the full period to that pay cycle (for example, the 1st through the last day of the month) and the partial period to your actual start and end dates.

Examples

  • Mid-month hire

    Annual salary $60,000, 12 monthly periods, full month March 1–31, worked March 15–31 → pay is about half of one monthly installment.

  • Biweekly payroll

    Choose 26 pay periods per year when your employer runs biweekly payroll instead of monthly.

FAQ

Does this include taxes or benefits?
No. The result is gross prorated pay before tax withholding, benefits, or employer-specific adjustments.
Why use calendar days instead of working days?
Many salary proration policies use calendar days for simplicity. For working-day proration, use the Working Days Calculator to count days separately.
What if partial days exceed the full period?
The partial range must fit inside the full pay period. Adjust your dates so the worked range does not exceed the defined period.
