What a personal loan costs in Seneca
A personal loan hands you a single sum and a repayment schedule of equal monthly installments over an agreed term.
Two loans can share an interest rate and still differ in APR once fees are counted, so compare APR; our personal loan calculator shows the difference over the full term.
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.
