How to Sum Hours and Minutes in Excel

Excel allows you to add time values using simple formulas and functions. You can sum hours and minutes by entering times in separate cells and using either basic addition or the SUM function.

Basic Time Addition

Enter times in the format hh:mm in separate cells. Use the formula =B2+B3 to add times together. The result displays in hh:mm format.

Using SUM Function

The SUM function can add multiple time values. Select your target cell and use =SUM(range) or click Home > AutoSum. This works for both Excel desktop and Excel web versions.

Handling Totals Over 24 Hours

Excel's default time format cannot display sums exceeding 24 hours correctly. Apply the custom format [h]:mm;@ to your result cell to show the total hours properly.

Using SUMIF for Conditional Time Addition

SUMIF allows you to sum hours and minutes based on specific criteria. The function requires three arguments: range, criteria, and sum_range.

Important Considerations

Excel stores times as decimal numbers with formatting applied. Time calculations work like regular number calculations. Ensure your time values are in the correct format before adding them together.

Key Use Cases for Time Calculations in Excel

Employee Time Tracking and Payroll

Track and calculate total hours worked by employees across different shifts or days within a week. This is essential for payroll processing and helps managers monitor overtime and labor costs.

Meeting and Event Duration Analysis

Calculate the total time spent in meetings, conferences, or events over any given period. This helps organizations optimize their time management and evaluate the resource allocation for various gatherings.

Project Task Time Management

Monitor and aggregate time spent on different project tasks to analyze team productivity and project progress. This enables better project planning and resource allocation for future initiatives.

Study Schedule Optimization

Keep track of time dedicated to different subjects or learning activities in an academic setting. This allows students and educators to assess time management effectiveness and adjust study schedules accordingly.

Travel Itinerary Planning

Sum up flight durations, layover times, and ground transportation intervals to create comprehensive travel schedules. This helps in planning efficient itineraries and calculating total journey times for business or leisure travel.
