As with home loans, customers can choose an effective interest rate loan that allows them to pay more than their normal installment to reduce the principal, and thus pay lower interest. Meanwhile, financing offered by some other institutions is based
on a flat interest rate, wherein customers are unable to reduce the principal or the interest from the amount fixed in the financing contract.
With effective interest rates, customers can determine their financial planning more efficiently, with no risk of rising interest rates that would incur higher costs to them in
the future.
