The EMI for a home loan of 30 lakhs is determined by the loan term, interest rate, and processing fee. The EMI would be around Rs. 24,600 if the loan was for 20 years and the interest rate was 7.5%. The processing fee, on the other hand, varies by lender and may raise the overall cost of the loan. A home loan EMI calculator can assist in determining the exact EMI for a 30 lakh home loan.
