How Percentage Calculations Work

The standard percentage formula is:

Percentage = (Part ÷ Whole) × 100

For finding a percentage of a number:

Value = (Percentage ÷ 100) × Number

For percentage increase:

New Value = Original Value + Increase

For percentage decrease:

New Value = Original Value − Decrease

These formulas are built into our calculator so users do not need to remember them.
