Frequently Asked Questions

Which repayment method saves more money?
Equal principal results in lower total interest but higher initial payments. Equal installment offers predictable monthly payments for easier budgeting.
When should I make prepayments?
Early loan prepayments provide maximum interest savings since interest comprises a larger portion of payments initially.
How do I choose the right loan term?
Longer terms reduce monthly payments but increase total interest. Keep payments under 50% of monthly income for financial stability.
