The video tutorial explains how to calculate continuous interest on a bank deposit. It introduces the continuous interest formula, which is simpler than the compounded interest formula.

Examples include calculating the balance after two and ten years using a principal of $1,500 and an interest rate of 4%. The video concludes with a preview of the next tutorial, which will cover determining the time required to reach a specific account balance.
