📖 How to Use

Discount calculator: enter the original price, then enter the discount level on a 0–10 scale (an East Asian retail convention) — 8 means you pay 80% of the price (i.e. 20% off), 7.5 means you pay 75%, and so on. Just type the number; no need to convert it to a percentage yourself.
The final price and the amount you save appear immediately below.
Percentage calculator (first pair): enter any number and a percentage to find what that percentage of the number equals — e.g. for "15% of 200," enter 200 in the Number field and 15 in the Percent field.
Percentage calculator (second pair): enter A (the part) and B (the whole) to find what percentage A is of B — e.g. to find what percentage 30 is of 200, enter A=30 and B=200.
The two calculators are independent — changing any field updates its own result instantly, with no button to press.

Note: The discount level field uses a 0–10 scale where a smaller number means a bigger discount (e.g. 5 = half price) — this is different from "percent off," so don't confuse the two when entering a value.
