Build models & dashboards faster with Watch Window
Here is a familiar scenario: You are building a dashboard. Naturally, it has a few worksheets – data, assumptions, calculations and output. As you make changes to input data, you constantly switch to calculations (or output) page to check if the numbers are calculating as desired. This back and forth is slows you down.
Use Watch Window to reduce development time.
What is Watch Window:
Watch Window allows you to monitor values in other worksheets. This is very useful when you are testing your calculations / model. As you make changes to the input values / assumptions, Watch Window instantly reports the output values. See below demo to understand how Watch Window helps you.

Adding Watches for VBA
Of course, Watches are a feature in almost all programming editors. Naturally, VBE also supports Watches. To add a watch to a variable / expression, just select it, right click and add Watch from the context menu.
Once you add a watch, you can monitor the expression / variable values when your code breaks. Alternatively, you can also ask VBE to break the code whenever your watch value changes.
