Step-by-Step Calculation
Calculate regular annual pay
Multiply the normal hourly rate by regular weekly hours and the number of paid weeks.
regularAnnualSalary = hourlyRate * regularHoursPerWeek * paidWeeksPerYear
Find the overtime hourly rate
Apply the overtime multiplier to the normal hourly rate.
overtimeHourlyRate = hourlyRate * overtimeMultiplier
Calculate annual overtime pay
Multiply the overtime rate by average weekly overtime hours and paid weeks.
annualOvertimePay = overtimeHourlyRate * overtimeHoursPerWeek * paidWeeksPerYear
Add regular and overtime earnings
Combine the two annual gross pay amounts.
annualSalary = regularAnnualSalary + annualOvertimePay
Calculate the monthly average
Divide the estimated annual total evenly across 12 months.
averageMonthlySalary = annualSalary / 12
Example: accountant with regular weekly overtime
Regular annual pay
$35.00 × 40 × 52
$72,800
Overtime hourly rate
$35.00 × 1.5
$52.50 per hour
Annual overtime pay
$52.50 × 5 × 52
$13,650
Estimated annual salary
$72,800 + $13,650
$86,450
Average monthly salary
$86,450 ÷ 12
$7,204.17
Final Result
Estimated annual gross salary: $86,450. Average monthly gross salary: $7,204.17.
Assumptions
- ✓The hourly rate, regular hours, and average overtime pattern remain the same during all paid weeks entered.
- ✓Overtime is paid at the entered multiplier for every overtime hour included in the estimate.
- ✓All amounts are gross pay before taxes, pension contributions, insurance, and other deductions.
- ✓The paid-weeks figure includes paid holiday or paid leave when those periods are paid at the applicable hourly arrangement.
Limitations
- !Actual hours can change during busy periods, client deadlines, seasonal work, or changes in workload.
- !Employment contracts may have different overtime eligibility, thresholds, rounding methods, or premium-rate rules.
- !The estimate excludes bonuses, commissions, allowances, benefits, reimbursed expenses, and employer contributions.
- !Monthly pay may vary even when the annual estimate is divided by 12, especially for employees paid by actual hours worked.
Common Mistakes to Avoid
Using 52 paid weeks when the role includes unpaid leave, a seasonal gap, or a shorter contract.
Entering total weekly hours as regular hours and also entering some of those same hours as overtime.
Entering 1.5% rather than 1.5 for a time-and-a-half overtime multiplier.
Using a net after-tax hourly amount instead of the agreed gross hourly rate.
Assuming the monthly average is the exact amount paid in every month.
