Overtime Calculator

The Overtime Pay Calculator estimates regular pay, overtime pay, total pay, and effective hourly rate from regular hours, overtime hours, base rate, and overtime multiplier.

Formula

$\text{Regular pay}=\text{Regular hours}\times\text{Base rate}$ $\text{Overtime pay}=\text{Overtime hours}\times(\text{Base rate}\times\text{Multiplier})$ $\text{Effective hourly rate}=\frac{\text{Total pay}}{\text{Regular hours}+\text{Overtime hours}}$

The default overtime multiplier is 1.5. The form accepts up to 168 regular and overtime hours and a multiplier of at least 1.

Worked example

For 40 regular hours, 5 overtime hours, and a $20 base rate:

1. Regular pay: 40 x $20 = $800.
2. Overtime rate: $20 x 1.5 = $30.
3. Overtime pay: 5 x $30 = $150.
4. Total pay: $950.

Questions

Is 1.5x required everywhere?

No. Overtime rules depend on jurisdiction, employment classification, agreement, and hours worked. The multiplier is an input assumption.

Does this include tax or deductions?

No. It calculates gross modeled pay only.

What if there are multiple overtime tiers?

Apply each tier separately or use a payroll system that supports the applicable rules. This calculator uses one multiplier.

Limitations

The result is an arithmetic estimate and does not determine legal overtime entitlement, premiums, breaks, or payroll withholding.
