The tow charge calculator is an excel spreadsheet designed with formulas which automatically calculate the charges based on specific criteria. These formulas allow attendants to input the day the vehicle was impounded and the release date, which will produce an automatic calculation of how much money owed on the vehicle to release to the customer. This streamlines the process as it can be time consuming to physically count days using a calendar and a calculator, reduces the likelihood of errors, customers paying inaccurate charges, and misappropriation of assets.
