It’s worth noting that automatic calculation may slow down performance when dealing with large datasets. In these situations, users might prefer manual options to optimize system performance.

A senior analyst once spent hours trying to perform complex calculations in a large workbook with high volatility of data input. After enabling automatic calculations, his workbook froze due to the system consuming too much memory. He eventually had to deactivate automatic calculation and resort to manual recalculation for optimized performance.

Manual calculation: When you want Excel to stop running wild with numbers and actually listen to you.

### Manual Calculation

The process of performing calculations on Excel workbooks can be adjusted to suit your preferences. One such option is the ability to enable manual calculation mode, which allows you to manually control when calculations are performed within a workbook.

Many users prefer manual calculation as it provides an additional level of control over their calculations. It allows them to ensure all entries in a worksheet are correct before making any final calculations. In some cases, they may also want to delay recalculations until all data has been entered.

Interestingly, manual calculation was introduced because early versions of excel had slower processors that could not manage automatic updates across all cells simultaneously. As such, users often opted for manual controls to prevent excel from crashing due to having too many updated cells at once.

Take control of your calculations like a boss by forcing manual calculation in Excel.
