What a personal loan costs in New Underwood
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.
A longer repayment period spreads the cost and increases the interest paid, so compare total cost, not just the monthly figure.
A payment that strains the budget is a warning sign; a smaller loan or a little more saving time is the safer route.
