About this tool
Percentages hide in plain sight: sale discounts, tips, tax, grade scores, investment returns. DrokyAi's calculator covers the four questions people actually ask — what is X% of Y, what percent is X of Y, percentage increase/decrease, and sale discounts — and shows the formula with your numbers filled in, so you learn the math instead of just getting an answer. Discount mode breaks a sale price into the amount saved and the final price, which is exactly what you need standing in a store aisle.
