Clear answers about how CalcHub Pro calculates interest, taxes, health ratios, and data security.

Yes, absolutely. Every calculator across our platform is completely free forever. You do not need to register, create an account, enter credit card details, or pay any subscription fees.

Our loan tools (Home Loan, Car Loan, Personal Loan, and General EMI) use the reducing-balance amortization formula: EMI = [P ร— r ร— (1+r)^n] / [(1+r)^n - 1]. Here, P represents the principal amount borrowed, r is the periodic monthly interest rate (annual rate divided by 12 and 100), and n is the total number of monthly payments. This matches standard banking formulas used by HDFC, SBI, ICICI, and Axis Bank.

Never. CalcHub Pro operates on a strictly client-side architecture. All calculations are executed locally inside your web browser using JavaScript. No financial amounts, interest rates, weights, heights, or dates of birth are ever transmitted to or stored on our servers.

Yes. CalcHub Pro is fully responsive and optimized for touch devices on Android and iOS. Once any calculator page is opened, the mathematical scripts cache in your browser memory and will continue to work smoothly even if you temporarily lose internet connectivity.

When you select "Add GST (Exclusive)", the tax amount is calculated as (Base Price ร— Rate) / 100 and added on top. When you select "Remove GST (Inclusive)", the base cost is extracted using Base = (Gross Price ร— 100) / (100 + Rate), and the remaining difference represents the GST amount. Both methods automatically split the tax into equal CGST and SGST portions for intrastate transactions.
