Pro-Rata Salary Calculator

How pro-rata pay works

Pro-rata means "in proportion." A part-time salary is the full-time figure scaled by the fraction of full-time hours you work. If full-time is 40 hours a week and you work 24, you earn 60% of the full-time salary.

Pro-rata salary = full-time salary × (your hours ÷ full-time hours)

Pro-rata salary FAQ

How do I calculate pro-rata salary?

Multiply the full-time salary by your hours divided by the full-time hours. For example, a $50,000 full-time salary at 24 hours a week against a 40-hour week is $50,000 × (24 ÷ 40) = $30,000 pro-rata.

What does pro-rata mean on a job advert?

It means the quoted salary is the full-time equivalent. Your actual pay is scaled to the hours you work, so a part-time role advertised at a full-time figure pays proportionally less.

Is pro-rata pay calculated before or after tax?

Pro-rata scales your gross (before-tax) salary. Income tax, FICA and any state tax are then applied to that lower gross amount, so your take-home is reduced too.

Do pro-rata employees get holiday pay?

Yes — part-time and pro-rata staff are generally entitled to paid leave scaled to the hours they work, though the exact rules depend on your employer and local law.
