What a personal loan costs in St. John
The defining feature of a personal loan is the fixed installment: the same payment every month until the term ends.
The advertised interest rate leaves out fees that the APR captures, which is why APR is the number to weigh; try the personal loan calculator before you apply.
Lenders weigh your credit history, income and debts when they set the rate, and the term you choose then determines how that rate compounds into total cost.
Most lenders offer pre-qualification with a soft credit pull, so you can see an estimated rate and amount without affecting your credit score.
