How does this calculator work?
Prorated pay = Annual salary ÷ Pay periods per year ÷ Total working days in period × Days worked. On a $60,000 salary with 22 working days in a monthly period, the daily rate is $227.27. Working 15 days gives a prorated gross pay of $3,409.09. This is a gross (pre-tax) estimate.
Formula
How this is calculated
When an employee works fewer days than a full pay period — because they started or left mid-cycle — payroll calculates a prorated amount rather than a full period payment. The standard working-days method divides the full period gross pay by the total scheduled working days in that period to get a daily rate, then multiplies by the number of days the employee was actually present.
Full period gross pay is derived from the annual salary: divide by 12 for monthly payroll, 26 for bi-weekly, or 52 for weekly. The daily rate then converts that period pay into a per-day figure. This method is fair because it ties pay to actual scheduled workdays rather than calendar days, avoiding distortion from weekends and public holidays falling unevenly across months.
Note that this calculator computes gross (pre-tax) prorated pay. Actual net take-home pay will depend on income tax brackets (which may differ for a partial payslip), payroll deductions, benefits contributions and employer-specific payroll rules. Many employers also have their own HR policy on proration — confirm with your payroll department for the binding figure.
Frequently asked questions
Most months have 20–23 working days (Monday to Friday, excluding public holidays). A common default is 22. The exact count depends on the calendar month and your country's public holidays — use the actual scheduled days in the specific pay period for the most accurate result.
A partial payslip may push income into a different withholding bracket than a full period payment, but your total annual tax liability should be the same at year-end if you work the full year. Some jurisdictions annualise payslips for tax purposes to smooth this out. Consult your payroll team or a tax adviser if the tax impact is significant.
Yes — select the matching pay period. For bi-weekly payroll the annual salary is divided by 26; for weekly it is divided by 52. Enter the actual number of scheduled working days in the specific two-week or one-week period, then the days you worked.
