Im looking for new jobs on the net and not sure what the annual salary to hourly pay is. Is there a formula I need to know or a site that I can find to help? For instance, one ad says they pay 55,000 - 60,000 annually and another says they specifically pay 42,759 annually. So how do I figure it out.

Divide the annual salary by 2088. 55,000 annual is 26.34 hourly.

Based on 40 hour week,
divide annual salary by 2080 and NOT 2088.

42,759 / 2080 = 20.41 an hour.
