| Weekly | 52/year | 40 hours |
| Bi-weekly | 26/year | 80 hours |
| Semi-monthly | 24/year | ~86.67 hours |

- Overtime: Hours over 40 at 1.5× rate
- Double time: Alguns states/contracts require 2× for certain hours
Exemplo
Employee works 48 hours at $20/hour:
- Regular: 40 hours × $20 = $800
- Overtime: 8 hours × $30 (1.5×) = $240
- Total: $1,040
Hourly to Salary Conversão
Hourly to Annual
Hourly rate × 2,080 = Annual salary
Exemplo: $25/hour × 2,080 = $52,000/year
Annual to Hourly
Annual salary ÷ 2,080 = Hourly rate
Exemplo: $75,000 ÷ 2,080 = $36.06/hour
