How much does a cosigner help on personal loans?

A cosigner can help on personal loans, in certain circumstances. If you have strong credit qualifications and enough income to gain loan approval, a cosigner may have a modest impact, if at all. On the other hand, if your credit is less-than-stellar, your income is on the lower end, or you don’t have a lengthy employment history, applying with a credit-worthy co-borrower can make a big difference in your chances of approval as well as the interest rate you receive.
