What a personal loan costs in Dupo
Personal loans are closed-end installment debt, so the monthly payment and the payoff date are known from the start.
APR, not the simple interest rate, reflects what the loan actually costs once fees are included; the personal loan calculator puts a figure on it.
Choosing a longer term eases the monthly budget but adds interest over the life of the loan; a shorter term costs more per month and less overall.
Work out the payment you can comfortably carry each month first, then borrow no more than that figure supports.
