When you take out a large loan, the lender is taking on more risk than if you were to take out a smaller loan. The more money you borrow, the higher your interest rate will be. If you currently have several high interest loans, it could be worth looking into debt consolidation in order to lower your monthly payment and simplify your bills. If you have a high amount of monthly debt compared to your income a lender is likely to assign you a higher interest rate. If you have bad credit, you are likely to receive a higher interest rate so that the lender can make sure it makes its money back even if you default on the loan. Your credit score indicates to lenders how likely you are to pay back a loan. The better your credit, the more likely you are to qualify for a lender’s lowest interest rates.
