How to use the part time to full time salary calculator
- Choose whether you know a part time hourly wage or a full time salary.
- Enter the wage or salary, the part time hours per week, the full time hours per week and the paid weeks per year.
- Read the yearly pay at part time and at full time, the share of full time hours and the monthly equivalents.
- Switch the starting point to compare the other direction.
Formula
Part time pay = hourly wage x part time hours x paid weeks
Full time pay at the same wage = hourly wage x full time hours x paid weeks
Hourly rate from a salary = salary / (full time hours x paid weeks)
Share of full time = part time hours / full time hours x 100
Results are gross pay before tax. The same hourly rate is assumed at every number of hours.
$18 an hour at 25 hours a week
At $18 an hour for 25 hours over 52 weeks, part time pay is $23,400 a year. The same wage at 40 hours is $37,440, which is $14,040 more. Part time hours are 62.5% of full time hours, so the pay is also 62.5% of the full time figure.
Going the other way, a $52,000 full time salary works out to $25 an hour over 40 hours and 52 weeks. At 25 hours a week that pays $32,500 a year.
Why compare the two
When a job is offered for fewer hours, a yearly figure for the full time role can be misleading. Pro rating shows what the same hourly pay would give for your hours, or what a full time salary would be worth if you worked part of it. It also helps when moving between part time and full time within the same company.
If you need other conversions, such as monthly or biweekly pay, the hourly to salary calculator shows every pay period. Headcount in full time equivalents is covered by the FTE calculator.
What is not in the figure
Benefits such as health coverage or paid time off often depend on hours, and some employers set different pay for part time and full time staff. Overtime, bonuses and unpaid weeks are not included unless you adjust the paid weeks. Use the gross pay calculator to include overtime on top of the base rate.
Assumptions and limits
- Gross pay only, before taxes and deductions.
- The hourly rate stays the same at part time and full time.
- Full time hours are whatever you enter, not a legal or company definition.
- Benefits, overtime, bonuses and pro rated time off are not included.
Frequently asked questions
How do I convert a part time wage to a full time salary?
Multiply the hourly wage by the full time hours per week and by the paid weeks. At $18 an hour, 40 hours and 52 weeks, that is $37,440.
How do I pro rate a full time salary for fewer hours?
Multiply the salary by part time hours divided by full time hours. A $52,000 salary at 25 of 40 hours is $32,500.
What does full time equivalent mean?
It is the share of a full time schedule that a part time schedule represents. Twenty five hours against forty is 0.625 of a full time equivalent.
Should I count paid weeks as 52?
Use 52 if you are paid for every week of the year. Use fewer if some weeks are unpaid, because unpaid weeks lower the yearly total.
