The shortcut everyone learns is that an hourly rate of $20 equals roughly $40,000 a year. The arithmetic: 40 hours a week, 52 weeks a year, so 2,080 working hours per year, and $20 × 2,080 = $41,600. The rule is genuinely useful for a glance — and dangerously incomplete when real schedules, vacation and overtime come into play.
The base conversion, both directions
To go hourly to yearly, multiply the rate by hours per week, then by weeks per year. To go the other way, divide the annual salary by the same product. The formula generalizes cleanly to monthly, biweekly, weekly and daily equivalents — which is exactly how an hourly-to-salary calculator breaks it down.
annual = hourly × hoursPerWeek × weeksPerYear monthly = annual / 12 weekly = hourly × hoursPerWeek
When the 2,080 rule lies to you
- Unpaid leave: the rule assumes 52 paid weeks. Two weeks of unpaid vacation means 50 — a real, measurable difference in annual income.
- Overtime and shifts: hourly roles with overtime, night premiums or irregular shifts do not fit a flat-times-2,080 figure.
- Part-time schedules: fewer hours per week is a linear change, but benefits and overtime thresholds often are not.
- Salary roles: most salaried positions quote annual pay directly, so the rule is only useful for comparing against the hourly world.
The single most important adjustment is weeks per year, because it is the value people almost always set and forget. If your employer grants paid time off, keep 52. If your time off is unpaid — or you are a contractor billing only for days actually worked — reduce it to 50 or 48 and compare offers on that number, not the default.
Comparing an hourly offer to a salary offer
Convert both to the same unit before comparing. A $45,000 salary against an $22-per-hour contract is not a fair duel unless you account for the contractor’s missing benefits, paid leave and employer payroll contributions. Convert the salary to its hourly equivalent, then decide how much to discount the contract for unpaid downtime and self-provided benefits.
The conversion itself is simple arithmetic and the tool shows its formula, so you can verify every figure. Because the calculation runs on your device with no upload, entering a real wage or a real offer stays completely private.
