Interest is the primary fee you will incur when getting a business loan. This is how lenders make their money and is, therefore, an unavoidable cost.
You may also incur costs for the processing of your business loan application, called an origination fee. In addition, there are late-payment fees, non-sufficient funds (NSF) fees, and prepayment penalties which come into play once the loan has been obtained.
The fees payable depends on the type of loan you are applying for, amongst other factors.
When speaking to a Comparewise vetted partner lender, make sure you discuss any potential costs you might incur upfront, so that you are aware of them.
