Explanation: This formula calculates the total interest paid over the life of the loan by subtracting the principal amount from the total of all monthly payments made.
Details: Understanding the total interest cost helps students make informed borrowing decisions, compare loan options, and plan for repayment strategies to minimize interest costs.
Tips: Enter your monthly payment amount in NZD, the total number of months in your loan term, and the original principal amount. All values must be positive numbers.
Q1: Does this calculator account for interest rate changes?
A: No, this calculator assumes a fixed monthly payment amount. For variable interest rates, the calculation would be more complex.
Q2: Are there any fees included in this calculation?
A: This calculation only includes the principal and interest components. Additional fees or charges are not accounted for.
Q3: How accurate is this calculation for NZ student loans?
A: This provides a basic estimate. For precise calculations, consult your loan provider as interest rates and terms may vary.
Q4: Can I use this for other types of loans?
A: While the formula works for any installment loan, this calculator is specifically designed for NZ student loan considerations.
Q5: What if I make extra payments?
A: Extra payments would reduce the total interest paid. This calculator assumes regular fixed payments throughout the loan term.
