What Is a Pro-Rata Salary? How to Calculate It
A pro-rata salary is a full-time salary scaled down to the hours you actually work. The phrase is Latin for 'in proportion,' and it's how part-time and job-share roles are usually paid and advertised.
The pro-rata formula
A worked example
If a full-time role pays $60,000 for 40 hours a week and you work 24 hours, you work 60% of full-time. Your pro-rata salary is $60,000 × 0.6 = $36,000 a year.
| Full-time salary | Your hours (of 40) | Pro-rata salary |
|---|---|---|
| $50,000 | 20 | $25,000 |
| $60,000 | 24 | $36,000 |
| $80,000 | 30 | $60,000 |
What to watch for
- Holiday entitlement is usually pro-rated too — fewer paid days off.
- Pension or retirement contributions often scale with your reduced salary.
- Some benefits (like health insurance) may have minimum-hours eligibility.

What does pro-rata salary mean?
Pro-rata salary is a full-time salary reduced in proportion to the hours you actually work. A 60%-time role pays 60% of the full-time figure.
How do I calculate a pro-rata salary?
Divide your hours by full-time hours, then multiply by the full-time salary. For 24 of 40 hours on $60,000, that's $60,000 × 24/40 = $36,000.
