What Is Prorated Salary?
A prorated salary is the portion of an annual salary that an employee earns based on the actual time worked. For example:
- If an employee’s annual salary is $60,000, but they work only 6 months, the prorated salary would be $30,000.
- This calculation ensures fairness in compensation when an employee does not work the full year.
Prorated salaries are common in situations like:
- Mid-year hiring
- Early resignations
- Contract or temporary employment
- Sabbaticals or unpaid leaves

Where:
- Annual Salary is your full-year compensation.
- Months Worked is the total number of months between your start and end date (inclusive).
By using this formula, the calculator ensures accurate monthly allocation of salary, avoiding manual errors.
