    How to Convert Between Hourly, Monthly & Annual Salary

    Comparing job offers and negotiating salary requires converting between different pay periods. An hourly rate, monthly salary, and annual salary all express the same earnings in different units of time. The conversion assumes a standard work year — typically 2,080 hours (52 weeks × 40 hours/week) in the US, though actual billable hours vary with paid leave, holidays, and overtime.

    The Formula

    Annual = Hourly × Hours per Week × Weeks per Year
    Annual = Monthly × 12
    Hourly = Annual / (Weeks per Year × Hours per Week)
    Monthly = Annual / 12
    Weekly = Annual / 52
    
    US standard: 2,080 hrs/year (52 weeks × 40 hrs)
    After deducting 10 federal holidays and 2 weeks vacation, effective hours = (52−3) × 40 = 1,960 hrs/year. Use 2,080 for total contracted hours, 1,960 for effective working hours.

    Step-by-Step Example

    A job offer is $28/hour, 40 hours/week. Convert to monthly and annual salary. Compare to another offer of $58,000/year.

    Given

    Hourly rate:$28/hrHours per week:40Weeks per year:52

    Solution

    1. 1
      Weekly pay: $28 × 40 = $1,120/week
    2. 2
      Annual salary: $1,120 × 52 = $58,240/year
    3. 3
      Monthly salary: $58,240 / 12 = $4,853/month
    4. 4
      Compare to $58,000 offer: $58,240 > $58,000 — the hourly offer pays slightly more

    $28/hr = $58,240/year = $4,853/month. The hourly offer pays $240 more annually.

    Common Mistakes to Avoid

    Using 2,080 hours without adjusting for paid time off — if a salaried role includes 3 weeks PTO, the effective hourly rate is higher than if unpaid.

    Comparing gross hourly to salaried gross without accounting for benefits — a salaried role with health insurance and 401(k) match has higher total compensation than the gross salary.

    Forgetting overtime — non-exempt hourly workers earn 1.5× for hours over 40/week; this can significantly change annual earnings.

    Not considering bi-weekly vs semi-monthly pay — bi-weekly means 26 paycheques/year; semi-monthly means 24. The monthly take-home differs even at the same annual salary.
