Formula and calculation questions
Questions about the math behind the results.

Accuracy and assumptions
Questions about what the calculator includes and what it leaves out.
Does this calculator include taxes or deductions?
No. It does not subtract tax, insurance, retirement contributions, or other payroll deductions.
Why might my payslip be different from the estimate?
Actual payroll may use different overtime rules, rounding methods, pay codes, or extra earnings not included here.
Does the calculator handle multiple overtime rates in one period?
No. This version assumes one overtime multiplier for all overtime hours entered.
Does it check whether my hours legally qualify as overtime?
No. It estimates pay from the numbers you enter and does not determine legal or contractual eligibility.
Inputs and results

What should I enter as overtime hours?
Enter only the hours paid at the overtime multiplier in that same pay period.
What if I worked no overtime?
Enter zero overtime hours. The calculator will show regular pay only.
Why is my effective hourly rate different from my base hourly rate?
Because it averages both regular and overtime earnings across all hours worked.
