I took a loan in sbi of Rs 180000 in 2011 of dec and my monthly installment is Rs 4700/- per month for 5 years tenure when it is going to finish?

Are you sure what you are asking?

as per your inputs, add 5 years or 60 months to Dec, 2011 then it will be Dec, 2016, like so.

if you have an option of pre-payment and able to pay earlier than it can be earlier than 5 years tenure as well.

if you are asking of what is the total amount you are paying for your loan than it is your installment * 60 = 4700 * 60 = Rs. 2,82,000/-. Hope I'm clear. Thanks.
