Pro rata salary
$36,000/yr
60.00% FTE
Quick answer: pro rata salary = full-time salary × (your hours ÷ full-time hours). Working 24 of 40 hours on a $60,000 full-time salary gives $36,000 (60% FTE).
How pro rata pay is calculated
Pro rata salary = full-time salary × (part-time hours ÷ full-time hours)
Days work the same way: 3 days out of 5 = 0.6 × the full-time salary. The result is your full-time equivalent (FTE) percentage.
Pro rata in the UK
- Part-time staff must get the same hourly rate, holiday pro rata (5.6 weeks) and access to bonuses and pensions as comparable full-time staff — Part-time Workers Regulations 2000.
- Holiday: 3 days a week = 16.8 days statutory, not 28.
- Bank holidays should be adjusted pro rata; part-timers who never work Mondays should not lose out.
Pro rata in the US
- The term usually means a reduced salary for reduced hours — the hourly rate should stay equivalent.
- Check benefit eligibility: many US healthcare and 401(k) match rules require 30+ hours a week.
- Some employers pro-rate bonuses and PTO accrual by FTE; ask which items are pro-rated in writing.
Frequently asked questions
What does pro rata mean?
"In proportion." A pro rata salary is the slice of a full-time salary that matches the hours or days you actually work.
How do I calculate pro rata pay for 3 days a week?
Divide 3 by 5 (0.6) and multiply the full-time salary by 0.6. On £40,000 that is £24,000.
Is pro rata the same as part-time?
Usually — pro rata describes the proportional pay calculation; part-time describes the working pattern.
