To find your annual salary, just take your hourly rate, double it, and add three zeros to the end. If you make $20/hour, you make approximately $40,000/year. If you make $30/hour, you make approximately $60,000/year.
This also works in reverse. To find your hourly rate, divide your salary by two and drop the three zeros. So $50,000/year becomes approximately $25/hour.
This is based on a general forty-hour workweek and doesn’t include taxes, but it’s a good general back of the napkin trick. And it’s most useful when you are deciding whether to buy something or not. If that pair of pants is going to cost you eight hours of work, is it worth it?
