How to Calculate a Price Increase
First calculate the increase amount by applying the percentage to the old price. Then add it to the old price.

Increase = (Old Price × Rate) ÷ 100
New Price = Old Price + Increase

If an old price is 1000 and the increase rate is 20%: Increase = 200, New Price = 1200.
