Have you ever spent the ride home trying to figure out what you owe the babysitter? The BabySitterCalculator easily provides you with the amount owed down to the minute. Simply enter in the hourly rate and the times that you left and arrive back home. You have the option of adding a tip percentage as well as an expense amount if you choose to reimburse the baby sitter for gas or meals or other activities that were paid for by the sitter. If you are a baby sitter this is a great tool for you as well as you can work out the money owed and email the invoice to the parents for their records. Parents, you can do the same for your baby sitter so they know how they are being paid.
