Percentage Change Calculator

Calculate the percentage increase or decrease between two numbers — useful for tracking month-on-month income or rate rises.

How it works

Percentage change is (new − old) ÷ old × 100. Use it to see how much your income grew this quarter, or to size a rate rise ("₹1,500 to ₹1,800 is a 20% increase") before you propose it to a client.

Frequently asked

How do I calculate a percentage increase?: Subtract the old value from the new, divide by the old value, multiply by 100. From ₹80,000 to ₹100,000 is (20,000 ÷ 80,000) × 100 = 25%.
