Frequently Asked Questions

How is GST calculated in India?

GST is calculated using the formula: GST Amount = (Original Cost x GST Rate) / 100. For intra-state transactions, it splits equally into CGST and SGST.

How does the EMI calculator work?

The EMI calculator uses the standard reducing balance loan formula: EMI = [P x R x (1+R)^N] / [(1+R)^N - 1], where P is Principal, R is monthly interest rate, and N is tenure in months.

Are regional Indian land measurements supported?

Yes! Our Land Area Calculator supports Bigha, Katha, Guntha, Cent, Ground, Acre, Hectare, and Square Yards.
