Complete Guide to Loan Amortization Calculator
What is Loan Amortization?
Loan amortization is the process of paying off a debt through regular payments over time. Each payment consists of both principal (the original loan amount) and interest components. Our amortization calculator helps you understand exactly how much of each payment goes toward principal versus interest throughout the life of your loan.
How Does the Amortization Calculator Work?
The amortization calculator uses the following formula to determine your monthly payment:
M = P × [r(1+r)^n] / [(1+r)^n - 1]
- M = Monthly Payment
- P = Principal (loan amount)
- r = Monthly interest rate
- n = Total number of payments

Understanding Your Amortization Schedule
The amortization schedule shows:

- Interest Payment: Cost of borrowing for that period
- Ending Balance: Remaining loan amount after payment
- Cumulative Interest: Total interest paid to date
Strategies to Save on Interest
Effective Ways to Reduce Total Interest:
- Make Extra Principal Payments: Even ₹1,000 extra monthly can save lakhs
- Bi-weekly Payments: Pay half monthly amount every two weeks
- Annual Lump Sum: Use bonuses to make principal payments
- Refinance to Lower Rate: Consider refinancing when rates drop
- Shorter Loan Term: Higher payments but significant interest savings
Frequently Asked Questions
What is negative amortization?
Negative amortization occurs when monthly payments are less than the interest due, causing the loan balance to increase over time.
Can I change my amortization schedule?
You can make extra payments to accelerate amortization or refinance to a different term, but the original schedule is fixed unless you modify the loan.
How does prepayment affect amortization?
Prepayments reduce the principal balance, which decreases future interest charges and can shorten the loan term significantly.
