Overtime Pay Calculator
Enter your numbers below to estimate weekly regular pay, overtime pay, and gross earnings.
Note: This estimate does not include taxes, deductions, or state-specific overtime rules.
How overtime pay works
Overtime pay is additional compensation for hours worked beyond a standard threshold. In many payroll systems, the default threshold is 40 hours per week, and overtime is paid at 1.5x the regular hourly rate (often called “time-and-a-half”).
This calculator overtime pay tool helps you quickly estimate your weekly earnings by splitting your time into regular and overtime hours, then applying the overtime multiplier.
Overtime pay formula
The calculator uses this structure:
- Regular Hours = the lesser of total hours worked and overtime threshold
- Overtime Hours = total hours worked minus overtime threshold (if positive)
- Regular Pay = regular hours × hourly rate
- Overtime Pay = overtime hours × hourly rate × overtime multiplier
- Gross Pay = regular pay + overtime pay + additional flat earnings
Example calculation
Suppose you earn $20/hour, work 47 hours, and overtime starts after 40 hours at 1.5x.
- Regular hours: 40 → Regular pay: 40 × $20 = $800
- Overtime hours: 7 → Overtime rate: $30/hour
- Overtime pay: 7 × $30 = $210
- Total gross pay: $800 + $210 = $1,010
If you also received a $50 flat bonus, your gross estimate becomes $1,060.
When this overtime calculator is useful
1) Budgeting and planning
If your hours change week to week, a quick estimate helps you plan bills, savings, and debt payments with less guesswork.
2) Checking your paystub
This tool can help you compare expected earnings to what appears on your check. If there is a large difference, it may be worth asking payroll for a breakdown.
3) Comparing shift options
Taking an extra shift often means some hours are paid at a higher rate. A calculator makes it easier to see whether extra time is worth it.
Common overtime mistakes
- Forgetting that overtime rules may differ by state, union contract, or industry
- Using daily overtime assumptions when your employer tracks weekly overtime (or vice versa)
- Not accounting for different overtime multipliers (1.5x vs 2.0x)
- Comparing gross pay to net pay without considering taxes and deductions
Frequently asked questions
Is overtime always after 40 hours?
Not always. While 40 hours/week is common, some jurisdictions or employment agreements have different rules. That’s why this tool lets you edit the threshold.
Can I use a multiplier other than 1.5?
Yes. Some contracts include double-time (2.0x) in certain cases. Set the multiplier input to match your agreement.
Does this include taxes?
No. This is a gross pay estimate. Your take-home amount will be lower after payroll taxes, benefits, retirement contributions, and other deductions.
Final thought
A fast, clear overtime estimate helps you make better financial decisions. Use this calculator overtime pay tool before your shift, after your week closes, or when reviewing your paycheck. Small weekly checks add up over time—and accurate numbers give you control.
