Suppose you're earning an hourly wage and want to determine your annual salary. Instead of calculating it by the week and multiplying, here's a simpler approach that requires no extra math.
Reddit user upcarl suggests a quick method: double your hourly rate, then add three zeros. For example, if you make $25 an hour, doubling it gives you $50, and adding three zeros results in $50,000. It won't be exact, but it's close enough for a rough estimate.
This method isn't new. Author Ramit Sethi shares it in his book, I Will Teach You To Be Rich, explaining when it could be useful:
This rule assumes a 40-hour workweek and doesn't factor in taxes, but it's a handy shortcut for quick calculations. It's often used when deciding if something is worth the price, like when evaluating if a $100 item is worth 8 hours of work.
