How this formula works

The percent-of equation is a direct scaling relationship: percentages convert to decimals, then scale a base quantity. This is the same operation used in discounts, tax computations, commissions, and portfolio allocations.

By keeping the transformation explicit, the calculator helps users avoid common mistakes such as mixing percentage points with absolute values. It also makes quick what-if analysis easy when totals change.
