How the calculation works

Each discount applies to the already-reduced price: Final = price × (1 − d1) × (1 − d2). Two 20% discounts are not 40% — they make 36%.

Do two 10% discounts make 20%?

No. They apply in sequence, resulting in a 19% total discount.

Calculate percentages every way: X% of Y, increase, discount and percentage change.
