Overtime is usually time and a half which means you get paid however much you get an hour plus half so if you make $8 an hour, during overtime you make $12 an hour. That being said if someone works 9-5, 5 days a week; that’s 40 hours a week. So two weeks would be 80 hours. $12 x 80 = $960 but you’re not giving me much context so I’m not sure if this is what you needed
