Wedding loan terms can vary. Typically, terms are declared before the loan is funded. If you need a lower monthly payment you may discuss a longer loan term with the lender. While it's extremely important to find a monthly payment you can afford, keep in mind that the longer the term, the more you may pay in interest. Terms available usually depend on the loan amount and the borrower's credit. In most cases, personal loan terms range between one to five years, but some lenders may offer terms up to twelve years.
