With rising home loan interest rates and evolving tax rules, many individuals face a critical choice— should surplus funds go toward prepaying their loan or building long-term wealth through SIPs? This piece compares both strategies across scenarios, helping you make an informed decision based on savings, returns, risk, and time horizon[EasyDNNnews:PaidContentStart]
S anjay Mahajan sat at his dining table, laptop open, two tabs side by side—one showing an online SIP calculator, the other his home loan amortisation schedule. His wife passed him a cup of tea, but he barely noticed. The numbers just wouldn’t line up. 'Should I throw this year’s bonus at the prepayment of home loan, increase the EMI a bit off the raise he got, or finally start that SIP I’ve been putting off?' he muttered, more to himself than anyone else. The idea of being debt-free faster was tempting. But so was the possibility of compounding returns if he invested instead. He’d read a dozen articles, watched YouTube videos, even asked his banker friend—only to end up more confused than ever. Like many Indians juggling aspirations, Excel sheets, and WhatsApp forwards full of financial wisdom, Sanjay was stuck. The idea of knocking years off his loan was appealing. So was the vision of sipping margaritas someday, funded by mutual fund returns.
For millions of Indians, a home loan is the bridge between aspiration and ownership—but it comes at a steep cost, not just in principal but also in interest. With current home loan interest rates ranging between 7.25 per cent and 9.5 per cent (as of July 2025) and property prices continuing to rise, borrowers today face a crucial financial decision: Should they prepay the loan, increase their equated monthly instalments (EMI) to reduce the tenure, or channel surplus funds into mutual funds via systematic investment plans (SIPs) to build long-term wealth? This question has become even more relevant with the new tax regime, where home loan interest is no longer eligible for deduction, and the exemption limit of tax has been raised to ₹12 lakh. The tax benefits that once justified holding on to a home loan have significantly diminished for those opting for the new regime. As a result, the decision is now more straightforward—but no less significant.
Choosing the right strategy can help save lakhs in interest or unlock substantial wealth over time. By balancing disciplined loan repayments with smart investments like SIPs, borrowers can manage debt efficiently while laying the foundation for a strong financial future.
Home Loan Strategy: Offset Interest with Smart EMI and SIP
Investments In India’s dynamic real estate market, home loans are a cornerstone of financial planning for millions of retail borrowers and investors. With property prices soaring and interest rates fluctuating, managing a home loan while building wealth is a pressing concern. A strategic approach combining disciplined EMI payments with SIPs in mutual funds can help borrowers reduce their loan burden while creating a robust investment portfolio. This article explores how to align EMI payments with SIP investments to offset home loan interest, save lakhs, and achieve long-term financial goals.
Home Loan Basics & Interest Dynamics
A home loan is a long-term loan secured against the property being purchased, typically spanning 15–30 years. The total cost includes the principal amount borrowed and the interest, calculated using the reducing balance method, where interest is applied to the outstanding principal, which decreases with each EMI. For instance, a ₹50 lakh home loan at 8.5 per cent annual interest over 20 years results in a monthly EMI of approximately ₹43,391. The total repayment would be around ₹1.04 crore, with ₹54.14 lakh as interest—over half the total cost. The table below illustrates the EMI breakdown over time:

Key Strategies with Home Loan and Prepayment and Investment
Lumpsum Prepayment: Making extra payments reduces the loan tenure and total interest. In case you choose to prepay the loan as and when you have the comfort of liquidity, it will reduce both your tenure and interest burden considering you are not reducing your EMIs. Assuming that you are prepaying ₹1,00,000 at the start of years 4, 5, and 6 (total ₹3,00,000), this reduces the loan tenure from 20 years to ~18.43 years, saving ₹7.57 lakh in interest. This is a guaranteed saving, as it directly reduces the interest paid to the lender. Now instead of prepaying the loan, you are investing ₹1,00,000 at the start of years 4, 5, and 6 (total ₹3,00,000) in a mutual fund scheme, that generates a return of 12 per cent p.a. and grows to ₹16.5 lakh by year 20. Compare this with a prepayment of the same amount from your home loan that results in a saving of just ₹7.57 lakh. The prepayment strategy yields a negative financial outcome of ₹8.9 lakh (₹16.5 lakh gained against ₹7.57 lakh saved). Hence, prepayment of principal may not work as the better option in this scenario.

If you seek guaranteed savings and want to reduce the loan tenure, go for prepayment, otherwise MF investment is preferable. It’s not always possible to do a prepayment of a large amount, hence a more practical strategy is to increase the EMI, which is the second strategy an investor can use and compare it with SIP.
SIP as a Wealth-Building Tool
SIPs allow investors to contribute a fixed amount regularly into mutual funds, leveraging compounding and rupee-cost averaging. Over time, this disciplined approach can build a substantial corpus to offset home loan interest or fund other goals. Equity mutual funds have historically delivered 12-15 per cent annualised returns over the long term, though past performance is not indicative of future results, however, if one remains invested for a longer duration, they can expect returns in the range of 10-12 per cent.
For example, investing ₹4,000 monthly (about 10 per cent of the EMI for a ₹50 lakh loan) in an equity fund at 12 per cent p.a. could grow to ₹39.57 lakh in 20 years, enough to cover most of the ₹54.14 lakh interest cost. Continuing with the above example of a ₹50 lakh home loan at 8.5 per cent annual interest over 20 years. If one has a ₹10,000 surplus, borrowers face a critical decision: increase the EMI by ₹10,000 per month to reduce the loan burden or invest that ₹10,000 monthly through SIP at an assumed 11 per cent annual return while continuing the original EMI for the full tenure.
Increasing the EMI from ₹43,391.94 to ₹53,391.94 shortens the loan tenure from 20 years to approximately 12.67 years, resulting in interest savings of ₹34.16 lakh. This approach offers guaranteed savings and frees up cash flow sooner, making it ideal for those prioritising debt freedom and risk aversion. Alternatively, investing ₹10,000 monthly in an SIP at 11 per cent p.a. generates a corpus of ₹91.98 lakh after 20 years. After offsetting the loan’s total interest of ₹54.14 lakh, this strategy yields a net gain of ₹37.84 lakh, surpassing the interest savings from the EMI increase. However, SIP returns are subject to market volatility, introducing risk compared to the certainty of prepayment savings. The SIP approach suits those with a long-term horizon and comfort with market fluctuations, aiming to not only offset interest but also build wealth.

A hybrid strategy—such as allocating ₹ 5,000 to EMI increase and ₹5,000 to SIP—could balance guaranteed savings with growth potential. Ultimately, the choice depends on risk tolerance, financial goals, and liquidity needs, and consulting a financial advisor is recommended due to the market risks associated with SIPs. The 'good EMI' strategy, where a parallel SIP offsets interest costs over time, is gaining traction.
Balancing Debt Repayment with LongTerm Wealth Creation
Financial experts emphasise the importance of strategically balancing home loan repayment with long-term investment planning. While servicing regular EMIs ensures credit discipline, it is equally crucial to invest any surplus funds to build wealth and maintain financial liquidity. Opting for a shorter loan tenure can help reduce overall interest outflow, although it increases monthly EMIs. This approach may be ideal for individuals with stable cash flows and a low-risk tolerance. On the other hand, investors who retain their investments—such as mutual fund SIPs—for extended periods (typically 5 to 7 years or more) stand to benefit from superior compounding returns, which could be compromised if funds are redirected to aggressively prepay debt. Ultimately, the choice between loan prepayment and wealth creation should align with one's financial resources, goals, and risk appetite. A blended strategy—continuing EMIs while deploying surplus into long-term investments—can optimise both interest savings and wealth accumulation.
Mutual Fund Categories To Invest
There are three basic mutual fund categories you can choose to invest. Equity Funds, which again has different sub-categories, offers a higher return in the range of 10-15 per cent in the long run. Nevertheless, they are volatile and returns can be negative for some period and hence, are suitable for long-term investment. This means that you have to start investing earlier in relation to your home loan tenure to get the most out of this investment. Hybrid Funds combine the best of both worlds — equity and debt. These funds aim to strike a balance between growth and stability by investing in a mix of stocks and bonds. The equity portion provides the potential for higher returns, while the debt portion helps reduce overall risk. Returns typically range between 8–12 per cent over the long term, depending on the sub-category you have chosen. While not as volatile as pure equity funds, they do experience some shortterm fluctuations. Hence, they are ideal for investors seeking moderate growth with a bit of cushion against market ups and downs — especially if your investment horizon is medium to long-term and you're not yet ready for the full risk of equities.
Debt Funds, on the other hand, invest primarily in fixedincome instruments like government securities, corporate bonds, and money market instruments. These are low-risk, low-return funds, generally offering returns in the range of 5–8 per cent. The risk of capital loss is minimal, especially if held for the intended duration, making them ideal for short to medium-term goals or for parking funds with some liquidity. This is suitable for someone who is nearing the closure of the home loan or is 5-7 years away from the closure of the home loan.
Who Should Use This Strategy?
This strategy is ideal for homeowners who have a stable income, a long-term perspective, and a willingness to take calculated risks. Recommended investment allocation would be 30-50 per cent of disposable income towards SIP investments and 20-30 per cent towards EMI payments. Homeowners who are nearing retirement or have a short-term financial goal may consider allocating a larger portion of their income towards loan repayments. On the other hand, young homeowners with a long-term perspective may consider allocating a larger portion of their income towards SIP investments.
Case Study 1: Young Homeowner
Continuing the above example, let's consider an example of a 30-year-old homeowner who takes a ₹50 lakh loan at 8.5 per cent interest for 20 years. He has a surplus income of ₹10,000 per month and wants to allocate 50 per cent towards EMI payments and 50 per cent towards SIP investments. By investing ₹5,000 per month in a diversified equity mutual fund, they can expect returns around 12 per cent per annum over the long term. This translates to a corpus of around ₹49.96 lakhs in 20 years. By increasing EMI by ₹5,000 every month, they can reduce the loan tenure by 4.42 years and save interest costs around ₹13.35 lakhs. This translates into total savings of around ₹63.5 lakhs. This amount is much lower than what he would gain by investing only in equities through SIP.

Case Study 2: Homeowner Nearing Retirement
Let's consider another example of a 50-year-old homeowner whose total remaining home loan is ₹20 lakh at 8.5 per cent interest for 10 years. He has a surplus disposable income of ₹30,000 per month and wants to allocate 60 per cent towards EMI payments and 40 per cent towards SIP investments. Since he is nearing his retirement (assuming he retires at the age of 60) he cannot take much of a risk by investing in pure equity funds. Hence, he invests in debt funds. By investing ₹12,000 per month in a debt mutual fund, he can expect returns around 8 per cent per annum over the investment period.

This translates to a corpus of around ₹22.10 lakhs in 10 years. By prepaying ₹21.60 lakhs, he can reduce the loan tenure by 5.25 years and save interest costs around ₹5.36 lakhs. So, he has total savings of around ₹28 lakhs.
Conclusion
In conclusion, by adopting a dual strategy of managing home loan EMIs and leveraging SIP investments, homeowners can offset interest costs and build wealth over the long term. By understanding how to align EMI payments with financial goals, selecting the right mutual funds, and exploring disciplined repayment strategies, readers can make informed decisions and potentially save lakhs in interest while building a robust investment portfolio. By following this strategy, homeowners can achieve their long-term financial goals and create a wealth-building asset that can help them navigate financial uncertainties. With discipline, patience, and the right investment strategy, homeowners can offset home loan interest and build a secure financial future.
