Assuming you mean a personal loan with a 0% APR:
There are a few ways to get a zero percent loan. The most common is to transfer your balance from one credit card to another that has a 0% introductory APR period. This can help you save on interest and pay off your debt faster. Another way to get a zero percent loan is to take out a personal loan from certain lenders who offer promotional rates. Be sure to shop around and compare offers before taking out a loan, as terms and conditions vary.
