Summary of "Should You Prepay Your Loan or Invest Instead? (Real Math Explained)"

The video discusses whether it is better to prepay a home loan or invest a lump sum amount instead, using a ₹5 lakh bonus as an example. The main focus is on balancing financial returns with peace of mind, rather than relying solely on complex calculations.

Main Financial Strategies and Insights:

Prepaying Loan vs. Investing:
- Prepaying a loan reduces interest burden and tenure, providing guaranteed savings.
- Investing in index funds can potentially yield higher returns but comes with market risks and volatility.
Loan Cost and Prepayment Impact:
- Example: ₹40 lakh home loan at 8.5% interest over 20 years results in ₹43.3 lakh interest.
- Prepaying ₹5 lakh early reduces loan tenure by 43 months and saves ₹10 lakh in interest.
- The freed-up EMI after loan closure can be invested, yielding additional returns (e.g., ₹18.7 lakh at 10% over 43 months).
Investment Returns vs. Loan Savings:
- Investing ₹5 lakh at 12% over 15 years could grow to ₹27.3 lakh.
- However, investing returns are uncertain and subject to market timing risks (start-point and end-point biases).
- Prepayment savings are guaranteed and risk-free.
Market Timing Risks:
- Start-point bias: Investing just before a market crash (e.g., 2008 financial crisis) lowers returns.
- End-point bias: Withdrawing investments just before a market downturn (e.g., March 2020) results in losses.
- These biases highlight the uncertainty of investment returns compared to loan prepayment.
Hybrid Approach:
- Splitting the amount between prepayment and investment can be a balanced strategy.
- Decision depends on comparing loan interest rates vs. expected investment returns.
- If loan interest > investment returns, prioritize prepayment.
- If investment returns > loan interest, partial investment can be considered.
When to Prefer Prepayment:
- Nearing retirement.
- Loans with high interest rates (e.g., credit cards, business loans, NBFC or small finance bank loans).
- Short tenure loans (3-5 years) where interest dominates early payments.
- Volatile job situations.
- Sole breadwinner with family liability concerns.

Step-by-Step Methodology to Decide:

Calculate total interest payable on the loan without prepayment.
Calculate interest savings and tenure reduction by prepaying a lump sum.
Estimate potential investment returns on the same amount over the loan tenure.
Consider market risks, start-point and end-point biases affecting investment returns.
Compare loan interest rate with expected investment returns.
Assess personal factors like job stability, retirement timeline, and family responsibilities.
Decide on full prepayment, full investment, or a hybrid approach based on above analysis.
Prioritize peace of mind over purely mathematical returns.

Key Takeaway:

Peace of mind and guaranteed savings from loan prepayment often outweigh the uncertain but potentially higher returns from investing, especially for risk-averse individuals or those with high-interest loans or unstable income.
