Calculates percentages, parts, and totals in three common scenarios.
A percentage calculator answers three common questions: what is X% of Y, X is what percent of Y, and X is Y% of what number.
• X% of Y = Y × (X / 100) • X as % of Y = (X / Y) × 100 • Base when X is P% = X / (P / 100)
What is 15% of 80? → 80 × 0.15 = 12. What percent is 12 of 80? → (12 / 80) × 100 = 15%.
