How to annualize hourly pay accurately
Why hours per week and paid weeks change your annual salary, how overtime and unpaid leave shift the total, and how to compare two job offers fairly.
The core formula and why order does not matter
Annualizing an hourly wage rests on one chain of multiplication: rate times weekly hours times paid weeks. Because multiplication is commutative, you can group it however you like and reach the same yearly number. A useful mental shortcut is that a $1/hr raise on a full-time 40-hour, 52-week schedule adds exactly $2,080 to the annual figure. That single fact lets you translate small rate changes into real yearly money without opening a spreadsheet.
Where the standard assumptions break
The tidy 40-by-52 default assumes you are paid for every week of the year and never work extra. In reality many roles include unpaid time off, seasonal gaps or contract breaks. If you take two unpaid weeks, your paid weeks drop to 50 and the annual total falls with it, even though your hourly rate has not changed. Lowering the weeks figure is the honest way to reflect that, rather than pretending the year is always fully paid.
Overtime, salaried roles and the hidden hourly rate
This tool models a flat rate, so it does not apply time-and-a-half or double time. If a job pays overtime, your true annual pay can sit well above the flat estimate, and you would need to add those premium hours separately. Running the math in reverse is just as revealing: divide a salaried job's yearly pay by your real hours worked to find its effective hourly rate. A salary that looks generous can shrink quickly once a 55-hour week is factored in.
Comparing offers on the same footing
Two offers only compare fairly when the schedule behind each is identical. A higher hourly rate at 30 hours a week can lose to a lower rate at 40 hours once both are annualized. Convert each offer to the same annual view, then remember these are gross figures. Benefits, paid leave, pension contributions and tax treatment can outweigh a modest gap in headline pay, so treat the annualized number as the starting point of the comparison, not the finish line.
