Overtime Pay Calculator

Use this calculator to estimate overtime pay from your hourly rate, standard weekly hours, overtime hours, and overtime multiplier. It is useful for planning shift work, checking payslip expectations, and comparing the value of extra hours.

What this calculator does

The overtime pay calculator separates regular earnings from overtime earnings.

It uses:

• hourly pay rate
• regular weekly hours
• overtime hours
• overtime pay multiplier

This gives regular pay, overtime pay, total weekly pay, and an annualized estimate.

How to use the overtime pay calculator

Enter your normal hourly rate, the number of regular hours worked in the week, overtime hours, and the overtime multiplier. A multiplier of 1.5 means time-and-a-half. A multiplier of 2 means double time.

Use the result as a gross pay estimate before taxes and payroll deductions.

Overtime Pay Formula

Regular pay = hourly rate x regular hours

Overtime pay = hourly rate x overtime multiplier x overtime hours

Total pay = regular pay + overtime pay

Example calculation

If:

• Hourly rate = 25
• Regular hours = 40
• Overtime hours = 8
• Overtime multiplier = 1.5

Then:

Overtime pay = 25 x 1.5 x 8 = 300

Regular pay is 1,000, overtime pay is 300, and total weekly pay is 1,300 before deductions.

What is overtime pay?

Overtime pay is extra compensation for hours worked beyond a standard threshold. The threshold and required multiplier depend on employment law, contract terms, location, and employer policy.

This calculator models the arithmetic, not legal eligibility.

Interpreting your result

Overtime can increase gross pay quickly, but net take-home pay may rise by less after tax and deductions. For after-tax planning, use the Paycheck Calculator.
