Key Scheme Rules & Highlights

  • 100% Goes to Principal: Unlike regular EMIs, every rupee of prepayment attacks principal directly.
  • Exponential Compounding: Prepayments made in early years save exponentially more interest than late prepayments.
  • Tenure vs EMI Reduction: Tenure reduction saves 2x–3x more interest than EMI reduction.
  • Annual Bonus Allocation: Channeling annual bonuses into loan prepayment is the fastest path to debt freedom.

About This Calculator

Prepayment & Early Loan Closure Calculator

See how extra monthly or lump sum payments save interest and cut years off your tenure.

What is it-

Loan Prepayment involves paying an additional amount towards your loan principal over and above your regular EMI. Prepaying directly reduces the outstanding principal balance, thereby saving compounding interest for all future remaining months.

How does it work-

Whenever a part-prepayment is made, the bank deducts 100% of the prepayment from the outstanding principal. You can then choose either: 1) Tenure Reduction (same EMI, loan closes earlier) or 2) EMI Reduction (same tenure, monthly cashflow eases).

Formula Used

New Principal = Old Outstanding - Prepayment Amount

Future interest is calculated strictly on the reduced Principal balance.

Key Factors

  • 2Exponential Compounding: Prepayments made in early years save exponentially more interest than late prepayments.
  • 3Tenure vs EMI Reduction: Tenure reduction saves 2x–3x more interest than EMI reduction.

Pro Tips

  • ✅Prepay in the first 5 years when the interest component of your loan is at its peak.
  • ✅Even a ₹5,000 extra monthly prepayment on a ₹40 Lakh loan can save over ₹10 Lakhs in interest.
  • ✅Always request an updated amortization schedule from your bank post-prepayment to verify balance deduction.

Loan Prepayment & Foreclosure: How to Become Debt-Free Faster

Taking a 20-year long-term loan involves a significant commitment. However, making strategic part-prepayments can materially shorten your loan tenure and potentially save a considerable amount of interest.

By allocating extra funds toward your loan, you can reduce the outstanding principal early on, which in turn reduces the interest calculated over future repayment periods.


📉 How Amortization Works

To understand prepayment, it helps to understand loan amortization.

At the beginning of a standard amortizing loan, a larger share of the EMI typically goes toward interest because the outstanding principal is highest. The exact proportion depends on the interest rate and tenure.

Interest on a reducing-balance loan is calculated according to the lender's applicable interest-calculation method, generally based on the outstanding principal. Reducing the outstanding principal earlier can reduce future interest costs.

Whenever a lump-sum prepayment is made, the calculator assumes the entered prepayment is applied fully to the outstanding principal. Actual treatment may depend on the lender, loan agreement, and any outstanding charges or dues.


💡 The Impact of Prepayment

Let's assume you have a ₹50 Lakh Home Loan at 9% for 20 Years.

  • Your EMI is ₹44,986.
  • Over 20 years, you will pay ₹57.9 Lakhs in interest.

Scenario A: Annual Lump Sum

Assuming a ₹1 Lakh prepayment is made at the end of each year and the EMI remains unchanged, the modeled payoff period is approximately 13 Years, potentially avoiding ₹22 Lakhs in future interest.

Scenario B: 1 Extra EMI Annually

Assuming one extra EMI (₹44,986) is paid at the end of each year and the regular EMI remains unchanged, the modeled payoff period is approximately 16 Years, potentially avoiding ₹12.5 Lakhs in future interest.

Scenario C: 10% Step-Up EMI

Depending on the prepayment amount, timing and interest rate, regular additional payments can materially shorten a long-term loan. If you increase your monthly EMI by 10% every year, the loan can be closed much faster, yielding substantial interest savings.


⚖️ Prepayment vs. Investment

A common dilemma is: "Should I prepay my 9% home loan, or invest that money?"

If an investment is assumed to earn 12% over the same period, its projected value may exceed the interest avoided through prepayment. However, investment returns are uncertain, while the interest avoided by prepayment is comparatively predictable.

A Hybrid Approach: Some borrowers may choose to divide surplus cash between loan prepayment and investments. The appropriate allocation depends on the loan interest rate, expected investment returns, taxes, liquidity needs, emergency savings and risk tolerance.


📝 Prepayment Rules & Fees

Prepayment charges depend on the loan type and applicable rules. Certain floating-rate loans to individual borrowers are subject to restrictions on prepayment charges, while charges may apply in other cases. Check your loan agreement and current lender terms before making a prepayment.

Other loan categories may have prepayment charges depending on the lender, product, and applicable regulations. Check the loan agreement for the applicable amount.
