Rs 40 lakh home loan: The EMI looks cheaper at 30 years, but there’s a costly catch, warns CA

A home loan can make buying a property feel more manageable by spreading the cost over several years. But a lower monthly EMI does not always mean you are paying less overall. CA Nitin Kaushik recently highlighted how dramatically the total interest can change when the tenure of a Rs 40 lakh home loan is extended. His calculation shows that while a longer tenure can ease monthly cash flow, it can also significantly increase the amount paid towards interest over the life of the loan.

Rs 40 lakh home loan: How tenure changes the EMI

CA Nitin Kaushik took to X to explain why borrowers should look beyond the EMI when comparing home loan tenures. For a Rs 40 lakh home loan at an interest rate of 9%, a 10-year tenure would result in an EMI of around Rs 50,668. The total interest payable over the period would be approximately Rs 20.8 lakh.

Extending the same loan to 20 years brings the EMI down to around Rs 35,987. However, the total interest rises sharply to approximately Rs 46.37 lakh. The difference becomes even more pronounced with a 30-year tenure. The EMI drops further to just Rs 32,182, but the total interest payable reaches roughly Rs 75.86 lakh.

Why a lower EMI can come with a higher cost

Kaushik pointed out that a lower EMI can make a loan appear cheaper than it actually is. The reduction in monthly repayment comes with a much longer period over which interest accumulates. This means borrowers looking only at the EMI could overlook the substantial difference in their overall repayment. At 10 years, the borrower pays around Rs 20.8 lakh in interest. At 20 years, that figure more than doubles to Rs 46.37 lakh. With a 30-year tenure, the interest component climbs to approximately Rs 75.86 lakh.

Is a longer home loan tenure always a bad idea?

According to Kaushik, not necessarily. He described a longer tenure as a cash flow decision, rather than automatically a poor financial choice. A borrower may deliberately choose a 30-year loan because the lower mandatory EMI provides greater flexibility in managing monthly expenses. However, opting for a longer tenure does not necessarily mean the borrower has to remain in debt for the entire 30 years.

The key distinction is between the loan tenure and the actual time taken to repay the loan.

How prepayment can reduce home loan interest

Kaushik suggested that borrowers whose cash flow allows it can consider prepaying the loan aggressively during the early years. Making additional payments towards the principal can reduce the outstanding loan amount and, consequently, the interest charged over the remaining tenure. This can help borrowers retain the flexibility of a lower mandatory EMI while potentially reducing the overall interest burden.

For individual borrowers, Kaushik also noted that RBI rules prohibit prepayment charges on floating-rate home loans. The Rs 40 lakh example therefore shows why the EMI alone does not tell the full story. A Rs 32,182 monthly payment may look attractive, but the 30-year option comes with roughly Rs 75.86 lakh in total interest.
