Overdraft Fee Calculator

How it is calculated

The tool adds a per-item charge to a single extended fee: item fees = F × N and total = F × N + X. F is the fee your bank charges for each overdrawn transaction, N is how many transactions were covered, and X is any extended (sustained) overdraft fee, entered as one lump sum rather than a daily rate. The extended fee is optional: left blank it counts as 0, so the total equals the item fees. Amounts are shown in US dollars with two decimals and the item count as a whole number. None of the three values can be negative, or no result is shown. The tool does not know your bank's rules, such as daily caps on fees, grace amounts or refunds, so use the fee schedule in your account agreement for F and X.

Common mistakes

• Counting the transactions that were declined: when the bank refuses a payment, an NSF-type fee may apply instead, and it should not be mixed into the number of covered items.
• Entering the extended fee per day without multiplying by the number of days it was charged. The field takes the total amount.
• Typing a fraction of an item, such as 2.5. The count must be a whole number of transactions; a fraction gives no result.
• Ignoring a daily limit on fees in the account terms, which can make the real total lower than F × N.
• Entering the overdrawn amount instead of the fee, which turns a small charge into an inflated total.
