Understand the concept of percentage
Before diving into the method, it is essential to understand what a percentage. Simply put, a percentage expresses a relative value compared to a total.

For a more detailed overview, check out this informative source.
Apply the three-step method
Step 1: Identify partial value and total value
The first step is to identify the two necessary values: the partial value and the total value. The partial value represents the quantity you wish to evaluate, while the total value is the reference against which you will carry out your calculation. For example, if you spend 40 euros out of a total of 200 euros, here, 40 euros is the partial value and 200 euros the total value.
Step 2: Use the percentage calculation formula
Once you have both values, it’s time to apply the formula to calculate the percentage. The formula is as follows: Percentage (%) = (Partial value / Total value) x 100. In our example, this would be: (40 / 200) x 100, which equals 20%. This means that the expense represents 20% of the total.
Step 3: Interpret the result
The final step involves interpreting the calculation result. In our example, a percentage of 20% indicates that you have spent a considerable fraction of your total. It is this interpretation that will allow you to draw conclusions about your finances or your expenses. For more context and examples, you can check out this useful resource.
