The maximum home loan tenure offered by all major lenders is 30 years. The longer the tenure, the lower is the EMI, which makes it very tempting to go for a 25-30 year loan. However, it is best to take a loan for the shortest tenure you can afford. In a long-term loan, the interest outgo is too high. In a 10year loan, the interest paid is 57% of the borrowed amount. This shoots up to 128% if the tenure is 20 years. If you take a `50 lakh loan for 25 years, you will pay `83.5 lakh (or 167%) in interest alone. Taking a loan is negative compounding. The longer the tenure, the higher is the compound interest that the bank earns from you. Sometimes, it may be necessary to go for a longer tenure. A young person with a low income won't be able to borrow enough if the tenure is 10 years. He will have to increase the tenure so that the EMI fits his pocket. For such borrowers, the best option is to increase the EMI amount every year in line with an increase in the income.

Increasing the EMI amount can have a dramatic impact on the loan tenure. Assuming that the borrower's income will rise 8-10% every year, increasing the EMI in the same proportion should not be very difficult. If a person takes a loan of `50 lakh at 10% for 20 years, his EMI will be `48,251. If he increases the EMI every year by 5%, the loan gets paid off in less than 12 years. If he tightens the belt and increases the EMI by 10% every year, he would pay off the loan in just nine years and three months
