To create a duration formula in Excel, simply subtract the start time from the end time to get the duration. Here's the step-by-step guide: Enter the start time in a cell (e.g., A2), enter the end time in the next cell (e.g., B2). Lastly, in another cell (e.g., C2), subtract the start time from the end time using the formula `=B2-A2`. Make sure both cells (A2 and B2) are formatted as 'Time' to accurately calculate and display the duration. This simple method helps track time intervals effectively.
