Common questions
What formula is used?
The standard amortization formula: EMI = P * r * (1+r)^n / ((1+r)^n - 1), where P is principal, r is the monthly interest rate, and n is the number of monthly payments.
Does this include fees or taxes?
No - this calculates principal and interest only. Insurance, taxes, and lender fees are not included.
