Prorated Salary Calculator

What prorated salary means

Prorated salary means reducing a full salary entitlement to match only the portion of the period that was actually worked or paid. This is common in planning for job starts, job exits, unpaid leave, and other partial-period situations where the annual salary exists but the full pay period does not apply.

A prorated salary calculator is most useful when you want a clean gross-pay estimate from a simple daily-rate approach. It makes the underlying assumptions visible instead of hiding how the partial-period pay was derived.

The daily-rate proration method

This calculator first derives a daily rate from annual salary divided by annual workdays. It then multiplies that daily rate by the days worked in the period. For added context, it also shows what a full period would have paid under the same assumptions and how much pay was left unpaid because fewer days were worked.

Worked example: 72,000 annual salary with 14 of 22 workdays completed

Suppose annual salary is 72,000, annual workdays are 260, and the pay period contains 22 workdays. The daily rate is 72,000 divided by 260, which is about 276.92.

If only 14 of those 22 workdays were worked, the prorated salary estimate is about 3,876.92. Under the same assumptions, the full period would have paid about 6,092.31, so the unpaid portion is the difference between those two amounts.

What this proration estimate does not determine

This is a simple gross-pay planning calculator, not an employer-policy calculator. It does not model salary-basis rules, semimonthly vs biweekly payroll differences, public holiday treatment, overtime, taxes, deductions, or employer-specific proration conventions.

Use it when the daily-rate method is the right simplification for planning. If an employer handbook or contract defines proration differently, that documented rule overrides the estimate here.
