Balancing a checking account is easy. Start with the balance from your last checking account statement. Then subtract all checks that you've written that were not listed in this last statement or any previous ones. Also subtract any checkcard charges, automatic debits for insurance, loans or other payments, fees or other charges to be deducted from your checking account. Then add all the deposits that you've made into your checking account after the date of the last statement. The resulting amount should be the current balance of your checking account.
