Frequently Asked Questions
Are the results exactly what I'll receive or pay?
Results are estimates based on published tax and insurance rates and standard formulas. Actual amounts can differ depending on your employer's payroll rules or a bank's fees and preferential rates, so confirm with the institution before making an important decision.
Which loan repayment method should I choose?
Equal principal repayment has the lowest total interest but higher payments at the start. If you prefer the same payment every month, equal installment repayment is easier to manage. Compare all three methods instantly in the Loan Interest Calculator.
Which earns more interest, a deposit or an installment savings account?
At the same rate, a deposit earns more because the full amount earns interest from day one. Installment savings are paid in monthly, so each payment earns interest for a shorter time. Compare after-tax interest with the Savings Interest Calculator.
