Hourly ↔ Daily ↔ Weekly ↔ Monthly ↔ Annual
The default assumes 40 hours/week × 52 weeks = 2,080 work hours/year. If you get paid time off, use 50 weeks (2,000 hours). Some calculations use 2,087 hours (average accounting for leap years and 365/366 day variations in government work).
Salary: Stable income, often includes benefits (insurance, PTO, retirement), but overtime is typically unpaid. Hourly: Paid for every hour worked (overtime at 1.5× in most cases), flexible schedule, but income can be inconsistent and benefits may be limited.
