How to Round Timecard Hours Down to Tenths in Excel

Maira Mehtab Sep 22, 2026 870 views

Question details

The user needs an Excel formula to calculate total hours worked on a timecard and round the result down to the nearest tenth of an hour, where 6 minutes equals 0.1 hour.

Product: Excel
Device & OS: not provided
Scenario: Calculating daily timecard hours for payroll, specifically requiring the hours to be expressed in tenths.
Observed behavior: Requires a function combination that computes the time difference between arrival and finish times, converts it to a decimal, and rounds down partial six-minute periods.

Before you start

Ensure your arrival and finish times are properly formatted as time values (e.g., hh:mm) in your spreadsheet before applying the time difference formula.

Solution 1Recommended

Use ROUNDDOWN and MOD Functions to Calculate Time

By combining the MOD function to handle time differences and the ROUNDDOWN function to remove partial intervals, you can accurately track hours in tenths.

Excel stores time as a fraction of a 24-hour day, meaning 1 hour is represented as 1/24. Multiplying a time difference by 24 converts it into a standard decimal format.

The MOD function ensures that shifts crossing midnight are calculated correctly, while the ROUNDDOWN function forces the decimal down to 1 decimal place, ensuring partial six-minute periods are not counted.

Input the time values

Enter the employee's arrival time in cell B2 and the finish time in cell C2. Ensure they are entered in a standard time format like 07:05 and 15:45.

Enter the rounding formula

Select the cell where you want the calculated decimal hours to appear (for example, D2), and type the formula: =ROUNDDOWN(24*MOD(C2-B2,1),1)

Calculate the result

Press Enter to execute the formula. For a shift running from 07:05 to 15:45, the formula will correctly return 8.6 hours.

Why round down?: In a tenths-based payroll system, every 6 minutes equals 0.1 hour. Rounding down guarantees that a partial block (like 4 minutes) is dropped, adhering strictly to timecard rules.

Frequently Asked Questions

How do I round time to the nearest quarter hour instead?

To round to the nearest quarter hour (0.25), use the MROUND function with the formula =MROUND(C2-B2, "0:15")*24. If you need to strictly round down to the previous quarter hour, use the FLOOR function: =FLOOR(C2-B2, "0:15")*24.

Why does multiplying the time difference by 24 give me decimal hours?

Spreadsheet software processes 1 full day as the integer 1. Therefore, 1 hour equals 1/24. By multiplying the calculated time fraction by 24, you convert it into a standard numeric decimal representing hours.

What happens if a work shift goes past midnight?

The MOD function inside the formula, MOD(C2-B2,1), automatically handles midnight crossings. It prevents negative hour results by wrapping the time correctly within a 24-hour cycle.
