Calculate a Tip In Your Head Quickly

When it comes time for the tip, you don't want to waste time or pull out the calculator on your phone. To simplify how much you need to give for a tip, move the decimal in your total one place to the left to reach 10%. If your total is $20, you get $2 for a 10% tip. From there you can easily calculate a higher percentage. If you want to do a 15% tip, multiply that number by 1.5 ($3 in our example). For 20%, multiple by two, and so on. Of course, you do have a calculator in your smartphone, so if you don't mind pulling it out briefly, you can figure out the tip with a single calculation. Multiply your total time 1.[tip%]. So, for a 20% tip, multiply your total by 1.2. This will give you your new total. The difference between your new total and the subtotal will give you your tip amount.
