What a personal loan costs in Louisville
Personal loans are installment credit — one lump sum, repaid in equal monthly installments across a fixed term you agree to up front.
The number to compare is the APR, not the interest rate, because the APR folds in origination fees and other charges; our personal loan calculator will show what a given amount and term would cost.
A longer term reduces what you owe each month and increases the total interest, which is the trade-off to weigh before choosing one.
A payment that strains the budget is a warning sign; a smaller loan or a little more saving time is the safer route.
