A: Principal is the original loan amount borrowed, while interest is the cost of borrowing that money, calculated as a percentage of the principal.

A: Longer loan terms result in lower monthly payments but higher total interest costs over the life of the loan.
Q3: What is amortization?
A: Amortization is the process of paying off a loan through regular payments that cover both principal and interest, with the interest portion decreasing over time.
Q4: Are there other costs besides the monthly payment?
A: Yes, loans may include additional costs such as insurance, taxes, fees, or private mortgage insurance (PMI) that are not included in this calculation.
Q5: Can I pay off my loan early?
A: Most loans allow early repayment, but some may have prepayment penalties. Early payment can save significant interest costs.
