‘Your home loan is a trap’: CA explains how a Rs 50 lakh loan can cost you over Rs 1 crore

Buying a home is often seen as one of life's biggest milestones. But what if the biggest financial commitment you'll ever make quietly ends up costing far more than you expected? According to CA Nitin Kaushik, many borrowers focus only on the EMI while overlooking the total amount they repay over the life of the loan. In a recent post on X, the chartered accountant broke down the numbers behind a typical home loan and explained why he believes aggressive prepayment deserves far more attention.

CA Nitin Kaushik took to X and described a home loan as a "trap" that can make borrowers "pay for two houses while only owning one." He argued that many people have been conditioned to believe low-interest debt is always smart leverage, but for most homeowners, it becomes a slow transfer of wealth to the bank over decades.

The Rs 50 lakh loan that becomes Rs 1.04 crore

To illustrate his point, Kaushik used the example of a Rs 50 lakh home loan at an interest rate of 8.5% over 20 years. According to his calculation:


Loan amount: Rs 50 lakh
EMI: Rs 43,390 per month
Total repayment: Around Rs 1.04 crore
Total interest paid: Around Rs 54 lakh

Kaushik argued that borrowers are not simply purchasing a home. In his words, they are also "gifting the bank a second apartment" through interest payments.

Why your EMI mostly pays interest in the early years

One of the biggest misconceptions around home loans, according to Kaushik, is that every EMI significantly reduces the outstanding loan amount. He pointed out that during the first five years, nearly 70% of every rupee paid through the EMI goes towards interest rather than reducing the principal. As a result, borrowers build equity much more slowly than they often realise.

"If you're not prepaying," he wrote, "you're not building equity. You're servicing a liability."

Is investing instead of prepaying always a better idea?

A common financial argument is that borrowers should invest any surplus money instead of using it to prepay their home loan. Kaushik believes that strategy often sounds better in theory than in practice.
According to him, consistently outperforming an 8.5% home loan isn't easy.

To come out ahead, investments would need to generate roughly 11% to 12% annual pre-tax returns. Since markets fluctuate and returns are never guaranteed, he described the difference as "risk, not guarantee."
By comparison, prepaying a loan offers what he called a guaranteed, tax-free return by directly reducing future interest costs.

His preferred home loan repayment strategy

Rather than taking on the highest possible EMI from the start, Kaushik suggested a more flexible approach.
His strategy includes:
- Choosing a tenure of 25 to 30 years to keep the mandatory EMI lower.
- Maintaining a manageable EMI for financial safety.
- Making aggressive prepayments whenever additional cash becomes available.
- He advised borrowers to treat their home loan like a flexible investment that can be reduced whenever their finances improve.

One extra EMI every year could save lakhs

Kaushik also highlighted the long-term impact of making small additional repayments. According to him, paying just one extra EMI every year can shorten a 20-year home loan by nearly five years while saving more than Rs 13 lakh in interest. He described it as one simple move capable of creating a significant financial impact over time.

What about tax benefits?

Kaushik also argued that tax savings should no longer be the primary reason for carrying a home loan.
With the New Tax Regime, he noted that deductions under Section 24(b) and Section 80C have become largely irrelevant for many taxpayers.

In his view, paying around Rs 4 lakh in annual interest merely to save little or no tax should not be viewed as a sound financial strategy. Instead, he described it simply as an expense.

The power of increasing your EMI over time

Another suggestion Kaushik shared was to increase the EMI gradually as income rises. He claimed that increasing the EMI by just 5% every year as salary grows could allow a borrower to finish a 20-year home loan in less than 12 years.

According to him, the biggest benefit isn't just the money saved. It is reclaiming nearly eight additional years during which income is no longer committed to loan repayments.

Finance is about freedom, not just returns

Kaushik concluded by encouraging people to think beyond interest rates and investment returns.
He argued that borrowers often spend too much time trying to optimise a small difference between debt costs and investment returns while ignoring the broader impact of carrying a home loan for two decades.

A long-term liability, he said, quietly influences career choices, delays important life decisions and normalises financial stress.

"Finance isn't only math. It's freedom," Kaushik wrote, adding that the best investment is not always the one with the highest CAGR, but the one that leaves a person financially resilient and "unshakeable."
