What a personal loan costs in Rochester
Personal loans are closed-end installment debt, so the monthly payment and the payoff date are known from the start.
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.
The offer you receive reflects the lender's read of your credit, income and debts, and the term controls the balance between payment size and total interest.
Before you borrow, decide what the loan is for and whether the monthly payment fits a budget you can already meet without taking on new debt.
