About Us

HisabAdda is an independent website that makes everyday money maths simple for people in India. We build free calculators for loans, savings, investments and taxes, along with everyday health tools such as calorie, BMI and due date calculators, and explain the formula behind each one in plain English and Hindi.

What we believe

• Money decisions should not need a finance degree. Every calculator shows the result in rupees, with lakh and crore written out, and explains how the number was worked out.
• Your data is yours. All calculations run inside your browser. We do not ask you to sign up, and we do not store the numbers you enter.
• Accuracy matters. We use the same standard formulas that banks and fund houses use, and every page includes a worked example you can check by hand.

What we are not

We are not a bank, lender, broker or registered investment adviser, and nothing on this website is financial, tax or legal advice. Rates and rules in India change from time to time. Please confirm the figures with your bank, fund house or a qualified adviser before making a decision.

We are also not doctors or dietitians. Our health calculators give general estimates for healthy adults and are not medical advice. Please talk to a doctor about your health, diet, pregnancy or any medical condition.
