What a personal loan costs in Sullivan
With an installment loan the payment is fixed for the life of the loan, so the schedule is predictable from the first month to the last.
APR is the figure that lets you compare like with like, since it wraps fees into the rate; run your own numbers with the personal loan calculator.
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.
