Compound interest is a powerful financial concept that allows investments to grow exponentially over time. When interest is compounded daily, it means that interest is calculated and added to the principal balance every day.

This frequent compounding leads to faster growth of your investment compared to other compounding frequencies like monthly or annually.

Using an Excel spreadsheet as a daily compound interest calculator offers a convenient way to visualize and track the growth of investments over time. Let’s dive into the significance and step-by-step process of setting up a daily compound interest calculator in Excel.
