What a personal loan costs in Sinai
A personal loan hands you a single sum and a repayment schedule of equal monthly installments over an agreed term.
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.
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.
Pre-qualification is a good first filter: it shows the rate and amount a lender may offer before you agree to a full application and a hard inquiry.
