Frequently Asked Questions
EMI is calculated using: EMI = P × r × (1+r)^n / ((1+r)^n – 1), where P is loan amount, r is monthly interest rate (annual rate ÷ 12 ÷ 100), and n is tenure in months. Use our free EMI calculator for instant results without any manual calculation.
To add GST: GST Amount = Price × GST% / 100. Total Price = Price + GST Amount. To remove GST from MRP: Original Price = MRP / (1 + GST%/100). Use our free GST calculator to add or remove 5%, 12%, 18% or 28% GST instantly.
SIP (Systematic Investment Plan) is a method of investing a fixed amount in mutual funds every month. Returns are calculated using compound interest. Use our SIP calculator — enter monthly amount, expected return rate (12–15% typical), and tenure to see your wealth grow.
As of 2025, SBI and HDFC Bank offer among the lowest personal loan rates starting from around 10.5% p.a. However, your actual rate depends on your credit score, income, and employment type. Compare all banks using our bank EMI calculators.
