📌 Quick Primer — Key Loan Vocabulary

• Principal: The amount you borrow.
• Interest: Cost of borrowing (annual percentage rate or APR).
• Tenure: Repayment period (months/years).
• EMI (Equated Monthly Installment): Monthly payment covering principal + interest.
• Secured Loan: Backed by collateral (e.g., house, car); lower rates.
• Unsecured Loan: No collateral (e.g., personal loans); higher rates.
• Flat Rate vs. Reducing Balance: Flat charges interest on the full principal (costlier); reducing balance charges on the outstanding amount (cheaper). The Reserve Bank of India (RBI) recommends reducing balance for borrower savings.

3. Car / Auto Loans — Depreciation & Negative Equity Risk 🚗

Use For: Vehicle purchase.

Stats: U.S. debt exceeds $1.8 trillion (Federal Reserve, 2025); India’s portfolio grew 15% in 2024 (RBI).

📊 Chapter 2 — How Interest & EMIs Actually Work (Step-by-Step Math)

EMI Formula (Reducing Balance):
EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)

Insight: Long tenures increase interest; use reducing balance for savings.
