How pro-rata salary works
Pro-rata salary = Full-time salary × (Your hours ÷ Full-time hours)
Pro rata means "in proportion": you earn the same hourly rate as the full-time role, for fewer hours. A $60,000 full-time job (40 hours) worked at 24 hours/week pays $36,000 — a 0.6 FTE position.
What else gets pro-rated
| Benefit | Usually pro-rated? |
|---|---|
| Paid vacation days | Yes — 0.6 FTE of 20 days = 12 days |
| Employer 401(k) match / pension | Yes, follows salary |
| Health insurance | Often full if you clear the eligibility threshold (commonly 30h/week in the US) |
| Fixed allowances | Varies — check the contract |
The traps: dropping below benefits-eligibility hours can cost far more than the salary reduction, and workload often does not shrink proportionally — 0.6 pay for 0.8 workload is a bad trade. Agree on deliverables, not just hours.
Frequently asked questions
What is a pro-rata salary of $60,000 for 3 days a week?
Three 8-hour days is 24 of 40 hours (0.6 FTE), so the pro-rata salary is $36,000 per year, or $3,000/month.
What does FTE mean?
Full-Time Equivalent. 1.0 FTE is full-time; 0.5 FTE is half. Employers use it to compare staffing; your FTE fraction × full-time salary = your pay.
Is the hourly rate lower for part-time work?
Not with true pro-rata pay — the hourly rate is identical, only hours change. If a part-time offer implies a lower hourly rate than the full-time equivalent, that is a pay cut, not pro-rating.
Do part-time workers get benefits?
Depends on hours and employer. In the US, many health plans require ~30 hours/week for eligibility; retirement matches and vacation typically scale with your FTE fraction.
