1. What Is Loan Amortization And Diminishing Balance?

Loan amortization with diminishing balance method is a loan repayment structure where each payment covers both interest and principal, with the interest portion decreasing and principal portion increasing over time as the outstanding balance diminishes.

2. How Does The Calculator Work?

The calculator uses the EMI formula:

\[ EMI = \frac{P \times R \times (1 + R)^N}{(1 + R)^N - 1} \]

Where:

$ P $ — Principal loan amount ($)
$ R $ — Monthly interest rate (decimal)
$ N $ — Number of monthly payments
$ EMI $ — Equated Monthly Installment ($)

Explanation: This formula calculates the fixed monthly payment required to fully amortize a loan over its term, accounting for the reducing balance method where interest is calculated on the remaining principal.

3. Importance Of EMI Calculation

Details: Accurate EMI calculation is essential for financial planning, budgeting, and understanding the true cost of borrowing. It helps borrowers assess affordability and compare different loan options.

4. Using The Calculator

Tips: Enter the principal amount in dollars, annual interest rate as a percentage, and loan term in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between flat interest and reducing balance?
A: Flat interest calculates interest on the original principal throughout the loan term, while reducing balance calculates interest on the outstanding balance, making it more favorable for borrowers.

Q2: How does the EMI change with different interest rates?
A: Higher interest rates result in higher EMI payments, while lower rates reduce the monthly installment amount for the same principal and term.

Q3: Can I reduce my loan term by paying higher EMI?
A: Yes, paying more than the calculated EMI reduces the principal faster, which decreases the total interest paid and can shorten the loan term.

Q4: What factors affect my EMI amount?
A: EMI is determined by three main factors: principal amount, interest rate, and loan tenure. Higher principal or interest rates increase EMI, while longer terms reduce it.

Q5: Is there any advantage to making prepayments on my loan?
A: Prepayments reduce the outstanding principal, which decreases the total interest paid over the loan term and may shorten the repayment period.
