Excel 2016 IFS Function Overview
Introduction to the IFS Function in Excel 2016
Excel 2016 introduces the IFS function, a significant enhancement over traditional nested IF statements.
The IFS function addresses the complexities and clunkiness associated with nested IF statements, making it easier to construct formulas.
It simplifies the process of handling multiple conditions without requiring intricate nesting of IF statements or managing parentheses and commas.
Understanding Traditional IF Statements
Nested IF statements can lead to:
Difficulty in formatting due to numerous parentheses.
Complexity in tracking comma-separated arguments.
Example of a simple income statement used to illustrate forecasting:
Company revenue data for 2013, 2014, and 2015 is used for profit forecasting into the future.
Basic components of the income statement include:
Revenues from three historical years.
Cost of sales for those years, leading to gross profit calculations.
Operating expenses such as administrative and marketing costs.
Final calculation of operating profit.
Historical Data and Assumptions
Key Historical Ratios:
Revenue growth in 2014: 8%
Revenue growth in 2015: 3%
Cost of sales as a margin: 34% (defined as cost of sales divided by revenue)
Operating expenses as a percentage of revenue: 8% growth with slight adjustments.
Forecasting Future Revenue and Costs
Future Forecasting Methodology:
Revenue growth forecasted at 3% yearly.
Cost of sales is projected to be 37% of revenue moving forward.
The approach involves utilizing last year's numbers for projections.
Implementation of Operating Expense Forecasts
Various forecasting drivers for operating expenses are established:
1. Last year's operating expense margin (returning straightforward forecasts).
2. Last three years' average operating expense margin (for a more robust calculation).
3. Last two years’ average operating expense margin (a middle-ground approach).
Traditional IF Statement Construction Example
Traditional Nested IF Example:
If the user selects option 1, use last year's operating expense margin:
Formula:
IF(H2=1, E14, ...If the user selects two, take the average of the last three years.
If neither option is chosen, apply a third logical test for option three.
Emphasis on the difficulty and potential errors associated with nested IF statements, like missing parentheses.
Transition to Using the IFS Function
Introduction to how IFS simplifies the process:
IFS function allows for multiple conditions to be tested sequentially, with logical tests laid out cleanly with simple value return parameters.
Example for the IFS function:
IFS(H2=1, E14, H2=2, AVERAGE(...), H2=3, AVERAGE(...))
Benefits of using IFS over nested IFs include:
Enhanced readability, as it eliminates the need for complicated logical nesting.
Reduces chances of errors such as incorrect parentheses placement.
Key Functions and Logical Tests with IFS
Logical Tests Focus:
IFS allows for a series of logical tests directly, making evaluation straightforward:
Example constructs:
H2=1, providing outputs based on simplicity.The final condition can be kept as a general true statement to capture any remaining evaluations.
Emphasizes that the IFS function does not require an explicit false condition; the last true condition effectively serves this role.
Conclusion and Implications of IFS Function Use
The launch of the IFS function marks a critical improvement in Excel's capability for managing conditional statements:
Greater ease of use and user-friendliness, potentially increasing productivity.
Encourages users to adopt cleaner coding practices, steering them away from cumbersome nested structures.
Highlights the importance of transitioning to new tools within Excel for efficient data analysis and forecasting strategies.
