The Simple Formula to Calculate Percentage Increase

Many business owners assume it’s complicated, but it’s one of the easiest formulas in business math.

The Formula

Percentage Increase = [(New Value – Old Value) ÷ Old Value] × 100

 

Example for Better Understanding

Suppose your revenue grows from ₹50,000 to ₹70,000.

• Old value: 50,000

• New value: 70,000

• Increase: 20,000

Calculation:
(20,000 ÷ 50,000) × 100 = 40%

That means your revenue increased by 40%, giving you a clear picture of business improvement.
