What is the aim of using overdraft coverage in a bank account?

Using overdraft coverage in a bank account primarily aims to prevent checks from bouncing when there are insufficient funds. This service allows account holders to draw on additional funds, up to a certain limit, which provides a safety net for unexpected expenses or delays in deposits.

When a person writes a check or attempts a transaction that exceeds their available balance, overdraft coverage ensures that the bank honors the transaction instead of declining it or allowing it to bounce. This can help maintain the account holder's credibility with vendors and is often seen as a more desirable option than incurring bounced check fees or overdraft fees.

The other options, while related to banking in some context, do not align with the primary purpose of overdraft coverage. Increasing savings account interest rates does not relate to the function of managing a checking account's balance. Providing funds for investments is more about broader financial management than the specific mechanism of overdraft protection. Allowing unlimited withdrawals without fees does not accurately reflect overdraft coverage, as it still involves terms and potential fees related to the use of overdraft funds.
