What a personal loan costs in Eureka
Unlike a revolving credit card, a personal loan is closed-end: the balance falls on a fixed schedule and the payment does not change.
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.
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.
A useful rule is to keep the new payment inside the room your budget already has, so the loan eases pressure instead of adding to it.
