About the composition tool
Percentage composition shows how a total is divided across parts. This tool takes any set of values and gives you each slice as a share of the total. It also shows the running total to keep track. It is helpful for budgets, grades, survey results and anything where you need to present proportions that sum to 100%.
Type in each item and its value, then see the percentages line up. If the numbers do not add to 100 exactly due to rounding, that is fine. For publishing, you can round further or adjust as needed. The tool is great for quick breakdowns before you build charts elsewhere. It makes spotting dominant categories easy, which is the first step to useful analysis.
Stable Numbers keeps the workflow light. Add rows, type values, get percentages. It avoids errors and lets you check your thinking quickly. Whether it is an expense report, a stock count, or a mark scheme, percentage composition puts clarity in your hands. Bookmark it and you can drop in numbers whenever you need a share of total fast.
