Converting hourly pay to annual salary is one of the most common calculations in HR and compensation. The formula is simple: hourly rate times total annual hours. The standard assumes 40 hours per week and 52 weeks, giving 2,080 hours. Most comp benchmarks, job posting salary ranges, and offer letter conversions rely on this figure. Where the math gets tricky is part-time roles, roles with unpaid leave, and jobs with significant overtime or shift differentials that push actual annual earnings well above the base conversion.
The Standard 2,080-Hour Formula Forty hours per week times 52 weeks equals 2,080 hours. Multiply the hourly rate by 2,080 to get the annualized base salary. A $25/hour role annualizes to $52,000. A $40/hour role annualizes to $83,200. This figure is the apples-to-apples base for comparing hourly and salaried roles in the same job family.
Adjustments for Part-Time and Variable Schedules Part-time roles use actual weekly hours. A 25-hour-per-week role at $22/hour annualizes to $22 x 25 x 52 = $28,600. For employees with unpaid leave, reduce the hour count accordingly. For roles with guaranteed overtime, annualize the blended rate. See full-time hours for how employers define the baseline and FTE for how part-time hours aggregate.
Why the Conversion Matters for Comp Decisions The conversion is central to compensation band design, offer letter preparation, market benchmarking, and budget forecasting. Most salary surveys report annualized figures even for roles that are paid hourly, so HR needs to convert hourly market rates up to compare and convert internal salaried rates down for hourly candidates evaluating offers.
Making Hourly to Annual Conversions Part of a Clean Compensation Process Document the assumption (40-hour week, 52 weeks, no overtime) any time you annualize. When offers include shift differentials, hazard pay, or guaranteed overtime, annualize the blended rate rather than the base alone. For payroll budget forecasting, the 2,080 standard is the baseline; add expected overtime and leave adjustments for accuracy. BLS wage data uses the same 2,080-hour standard: bls.gov/oes .
