> The 12-hour shift pay calculator works out your pay for 12-hour shifts – regular hours plus overtime at time and a half – per shift, week, month and year, and your average hourly rate.

## Inputs

- Hourly wage
- Overtime multiplier (×)
- Regular hours per shift
- Shifts per week
- Also pay overtime above 40 hours a week

## Results

- Overtime hourly wage
- Pay per 12-hour shift
- Average wage per hour
- Hours per week
- Pay per week
- Pay per month
- Pay per year

## Formula

```
Pay per shift = regular hours × rate + (12 − regular hours) × overtime rate
Weekly pay = shifts per week × pay per shift (+ weekly overtime if over 40 h)
Average hourly = pay per shift ÷ 12
```

## Explanation

Nurses, firefighters and factory workers often work three or four 12-hour shifts a week. Whether hours over 8 a day count as overtime depends on your state (California has daily overtime) and your contract; federal law only requires overtime above 40 hours a week.

### Tips

- Tax figures here are estimates for planning – your actual tax depends on credits, deductions and local rules.
- Check the tax year and filing status before you rely on a result.
- Use gross (before-tax) figures unless a field asks for take-home pay.
- When in doubt, confirm with the tax authority's own calculator or a tax professional.

### Common mistakes to avoid

- Confusing marginal and effective tax rates.
- Adding sales tax to a price that already includes it.
- Forgetting payroll taxes (Social Security and Medicare) on wages.
