Understanding business overdraft interest rates and fees
When considering a business overdraft, it’s important to understand the various interest rates and fees that may apply. This knowledge can help you manage costs effectively and make informed financial decisions.
Interest rates for business overdrafts
- Most business overdrafts have variable interest rates. This means the rate can fluctuate based on market conditions. It can also impact your overall borrowing costs, so it’s essential to monitor interest rate changes regularly.
- Business overdraft interest rates are typically calculated daily on the outstanding balance. This means the longer you have funds owing, the more interest you’ll accumulate – so plan your cashflow accordingly.
Fees associated with business overdrafts
Monthly service fees (line fees) will apply to your overdraft facility limit.
