Real-World Example

Imagine you’re shopping and see a $120 shirt with a 20% discount:

• Input: Select “Percent of a number,” enter 20% and $120.

• Result: Discount = 20% of 120 = $24.

• Final Price: $120 – $24 = $96.

Now, you want to tip 18% on a $50 restaurant bill:

• Input: 18% of $50.

• Result: Tip = $9.

Finally, your savings grew from $1,000 to $1,250:

• Input: Percent change, original = $1,000, new = $1,250.

• Result: Percent increase = ((1,250 – 1,000) ÷ 1,000) × 100 = 25%.

The calculator handles each case instantly, making life simpler.
