Clockify is updating how the Decimal duration format <\/strong>handles calculations across the app to achieve higher precision across all reporting and revenue totals. <\/p>\n\n\n\n

This is currently available in a Beta rollout for select users that have Decimal duration format configured in their workspace settings. Once validated, this updated calculation logic will be rolled out to all workspaces using Decimal format. <\/p>\n\n\n\n

What is changing<\/h2>\n\n\n\n

Previously, Decimal mode automatically rounded the duration of individual time entries before calculating duration and amount formulas. Pre-rounding entries created small calculation discrepancies across Summary, Detailed, Weekly, <\/strong>et Attendance reports, <\/strong>as well as the Dashboard, Timesheets, <\/strong>et Rappels<\/strong>.<\/p>\n\n\n\n

How Legacy Calculation Logic Worked: <\/strong>The time entry\u2019s exact tracked time was converted and pre-rounded to the nearest 1\/100th of an hour (36-second block) to ensure a maximum of two decimal places when converted to hours.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Example: Tracking 20 Minutes<\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

    \n
  • Exact tracked time<\/strong>: 20 minutes (0.3333… hours)<\/li>\n<\/ul>\n\n\n\n
      \n
    • Pre-rounded value:<\/strong> 0.33 hours<\/li>\n\n\n\n
    • Impact on totals:<\/strong> Pre-rounding to the nearest 0.01 hour sets the entry to 0.33 hours<\/strong> (equivalent to 19 minutes and 48 seconds), and this value is used in formulas.<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n

      <\/p>\n\n\n\n

      With the new calculation logic, Clockify keeps the full duration<\/strong> of every time entry in calculations, without rounding. The app would only round to two decimal places at the very end when totals need to be displayed on your screen.<\/p>\n\n\n\n

      Example: Tracking 20 Minutes (New Logic)<\/strong><\/p>\n\n\n\n

        \n
      • Exact Tracked Time:<\/strong> 20 minutes (0.3333… hours)<\/li>\n\n\n\n
      • Displayed Total:<\/strong> 0.33 hours<\/li>\n\n\n\n
      • How it calculates:<\/strong> Because 20 minutes equals 0.3333… hours, standard decimal rounding (since the 3rd decimal place is less than 5) sets your displayed value to 0.33 hours while keeping your full 20-minute tracked duration intact and using its full unrounded duration in formulas.<\/li>\n<\/ul>\n\n\n\n

        Here are some examples of the updated calculation logic.<\/p>\n\n\n\n

        Before and After: Time Tracking<\/strong><\/strong><\/p>\n\n\n\n

          \n
        • Before:<\/strong> If a user logged three time entries of 20 minutes, each entry is rounded to 0.33 hours resulting in 0.99 hours<\/strong> total in the Timesheet.<\/li>\n\n\n\n
        • Future:<\/strong> Formulas now use full duration of each entry for the calculation (20 minutes = 0.3333\u2026 hours). When summed together, the three entries display 1.00 hour <\/strong>total in the Timesheet.<\/li>\n<\/ul>\n\n\n\n

          Before and After: Billable Amounts<\/strong>
          A team member with an hourly rate of $100 logs three separate 20-minute time entries.<\/p>\n\n\n\n

            \n
          • Before:<\/strong> Each 20-minute entry was rounded to 0.33 hours before calculating the amount (0.33 x $100 = $33), resulting in a total of 0.99 hours<\/strong> and invoice total of $99.00<\/strong>.<\/li>\n\n\n\n
          • Future:<\/strong> Formulas now use the exact full duration of each entry for the calculation (20 minutes = 0.3333\u2026 hours). When added together, the three entries total 1.00 hour <\/strong>and invoice total is $100.00<\/strong>.<\/li>\n<\/ul>\n\n\n\n

            How this affects historical data<\/h2>\n\n\n\n

            Because formulas now use full durations rather than pre-rounded decimals, applying this logic to existing time entries will slightly adjust how past totals are displayed.<\/p>\n\n\n\n

            If you re-run Time Reports (such as Summary, Detailed, or Weekly) or an Attendance Report for a past period (e.g. January 2026), you might notice a variance of around 0.01 per entry compared to historical reports.<\/p>\n\n\n\n

            \n

            If you need to verify past records for tax audits or billing reconciliation, you can use this official help article as documentation. It confirms historical totals shifted due to a platform update, not manual edits.<\/p>\n<\/div><\/div>\n\n\n\n

            Why we are making this change<\/h2>\n\n\n\n

            Inconsistent rounding rules between different pages and duration formats cause confusion and make cross-checking numbers difficult. Using full durations align calculation rules and give you more accurate, reliable numbers on every page.<\/p>\n\n\n\n

            Ce que vous devez faire<\/h2>\n\n\n\n

            The new calculation logic is applied automatically, and the legacy option is turned off.<\/p>\n\n\n\n

            If you find discrepancies with past data and need reports to match with past billing or tax periods, you can switch back to the previous calculation logic in the workspace settings. <\/p>\n\n\n\n

            To restore previous calculation logic:<\/p>\n\n\n\n

              \n
            1. Allez dans Param\u00e8tres de l\u2019espace de travail<\/strong><\/li>\n\n\n\n
            2. Trouvez Format de la dur\u00e9e<\/strong> in the General tab<\/li>\n\n\n\n
            3. Select the Round duration to 2 decimal places<\/strong> .<\/li>\n<\/ol>\n\n\n\n
              \"\"<\/figure>\n\n\n\n

              When enabled, durations are rounded to two decimal places before calculating formulas (e.g., 0.33 instead of 0.333333). This restores the previous calculation behavior across all reports and pages, preserving your past numbers.<\/p>\n\n\n\n

              Important Note on the Beta Period:<\/strong> This Beta period helps us test and refine the new calculations, making sure everything works smoothly with no discrepancies. The legacy calculation checkbox is a temporary option and will be retired in approximately one year, making the new precision logic standard for all Decimal workspaces. <\/p>\n\n\n\n
