Percentage of Total FAQ

1. Can the percentage be higher than 100%?
Technically, yes. If the "part" is larger than the "total" (e.g., spending more than you earned), the percentage will exceed 100%.
2. What if the total is zero?
Calculating a percentage of a zero total is mathematically impossible (division by zero). The result is undefined.
3. How do I round percentage results?
In most financial contexts, rounding to two decimal places (e.g., 25.45%) is standard for accuracy.
4. How is this different from percentage change?
Percentage of total finds a "slice" of a pie. Percentage change measures how much one value grew or shrank compared to its previous state.
