Yes, interest-free loans do exist. However, they are typically only available for a short period of time - usually around six months. After that, the interest rate will usually be higher than if you had taken out a loan with interest. It's important to read the terms and conditions of any loan before you agree to it so that you understand the full terms of the loan.
A personal loan with a low-interest rate or even an interest-free personal loan can be a great way to save money on interest and fees, but only if you repay the loan in full within the specified time. Make sure you understand the loan terms before you agree to it to be sure it’s the right choice for you.
