When businesses compare loan options, interest rates are usually the first thing they look at. While rates matter, they rarely tell the full story. The true cost of a business loan is made up of several components, and focusing only on the headline rate can lead to unexpected costs later.

Understanding Business Loan Interest Rates
Interest is the cost charged by a lender for borrowing money. In business lending, interest rates vary widely depending on the loan type, risk profile, and repayment structure.
Fixed vs Variable Interest Rates
Fixed interest rates remain the same throughout the loan term. This provides certainty and makes budgeting easier, as repayments do not change.
Variable rates can increase or decrease over time. While they may start lower, they expose businesses to future rate rises.
Common Fees Associated with Business Loans
In addition to interest, many business loans include fees that directly affect the total cost of borrowing. These are often overlooked at the comparison stage.
- Arrangement fees – Charged for setting up the loan
- Completion or drawdown fees – Payable when funds are released
- Early repayment charges – Applied if the loan is repaid ahead of schedule
- Late payment fees – Charged when repayments are missed
- Exit fees – Applied at the end of certain loan terms
APR vs Total Cost of Borrowing
APR can be useful, but it is not always a reliable comparison tool for business loans, especially where terms are short or fees vary.
A better approach is to look at the total amount repayable over the full term and assess whether the repayments are affordable.
How Loan Term Impacts Cost
Shorter terms usually mean higher repayments but lower total interest. Longer terms reduce monthly pressure but increase total interest over time.
Why Fast and Unsecured Loans Cost More
Speed and flexibility often come at a price. Fast funding and unsecured lending can carry higher rates and fees because lenders take on more risk and complete fewer checks.

Hidden Costs Businesses Should Watch For
Some borrowing costs are not immediately obvious. Businesses should pay close attention to compounding structures, restrictions on early repayment, and fees triggered by minor breaches.
Understanding the True Cost Before Committing
The true cost of a business loan is not just the interest rate. Fees, term length, repayment structure, and cash flow impact all matter.
