An overdraft happens when you spend more money than you have available in your bank account. Your balance can drop below $0, which means you now owe the bank money. This matters because overdrafts can lead to fees, declined payments, and trouble keeping track of your budget.
For students, understanding overdraft helps prevent small purchases from becoming expensive mistakes.
Banks may allow an overdraft if you have overdraft protection or if they approve the transaction anyway. For example, if you have 35, your balance becomes -30 overdraft fee, you may now owe $45 total.
The best way to avoid overdraft is to track your balance, know pending transactions, and spend only what is actually available.
Key Facts
- Overdraft = spending more money than your available account balance.
- New balance = available balance - purchase amount.
- If available balance = 35, then new balance = 35 = -$15.
- Total amount owed = negative balance + overdraft fee.
- Overdraft fees can make a small shortage much more expensive.
- Pending transactions, automatic payments, and debit card purchases can all cause overdrafts if you do not track them.
Vocabulary
- Overdraft
- An overdraft is when money is taken from an account even though the account does not have enough available funds to cover the transaction.
- Available balance
- Available balance is the amount of money you can currently spend after the bank accounts for holds and pending transactions.
- Overdraft fee
- An overdraft fee is a charge the bank may add when it covers a payment that is larger than your available balance.
- Pending transaction
- A pending transaction is a payment or deposit that has been started but has not fully posted to the account yet.
- Overdraft protection
- Overdraft protection is a bank service that may cover a shortage by moving money from another account or allowing the account to go negative.
Common Mistakes to Avoid
- Confusing current balance with available balance is a mistake because pending purchases or holds may reduce how much you can really spend.
- Ignoring small automatic payments is a mistake because subscriptions or app charges can overdraft an account when the balance is low.
- Assuming a debit card will always be declined is a mistake because some banks may approve the purchase and charge an overdraft fee.
- Only counting deposits after they fully clear is often overlooked, but spending a deposit too early can cause overdraft if the money is not yet available.
Practice Questions
- 1 A student has an available balance of 55. What is the account balance after the purchase, not including any fee?
- 2 Your account balance is -25 overdraft fee. How much do you now owe the bank in total?
- 3 A student sees 35 as the available balance because a card purchase is pending. Explain which number the student should use when deciding whether they can make a $40 purchase and why.
