On the other hand, an interest rate is the cost of borrowing money as a percentage of the loan amount per year. It is usually expressed as an annual percentage rate (APR) and takes into account the duration of the loan. Interest rates for business loans are the percentage of the total loan amount that a lender charges the borrower for the use of the funds. Essentially, it is the cost of borrowing money from a lender.
Interest rates are typically expressed as an annual percentage rate, and can vary depending on a number of factors, such as the borrower’s credit score, the purpose of the loan, the term of the loan, and the lender’s risk assessment of the borrower’s ability to repay the loan.
Business loans with lower interest rates are usually reserved for businesses with good credit scores, while higher interest rates are typically offered to businesses with lower credit scores or higher perceived risk.
Unlike factor rates, interest rates are usually calculated on a monthly or daily basis, and the total repayment amount will vary depending on the length of the loan term and any additional fees or charges. If you pay off a loan quickly, you’ll pay less in interest. Not so with business financing that uses a factor rate.
Calculating Interest
The calculation of business loan interest rates can vary depending on the specific terms of the loan. However, interest is typically calculated as a percentage of the outstanding loan balance that is due on a regular basis (usually monthly). To calculate the amount of interest owed for a given period, you can use the following formula:
Interest = (Remaining Loan Balance x Interest Rate x Time Period) / 12

Outstanding Loan Balance is the amount of the loan that remains unpaid.

Interest Rate is the percentage rate at which interest is charged, expressed as an annual percentage rate (APR).

Time Period is the length of time (in months) for which interest is being calculated.
For example, if a business borrows $100,000 at an interest rate of 6% per year for a loan term of 24 months, the interest calculation for the first month would be:
Interest = ($100,000 x 6% x 1) / 12 Interest = $500
This means that for the first month of the loan, the business would owe $500 in interest. The total repayment amount would be the sum of the interest and the principal (i.e., the amount borrowed).
Advantages of Interest Rates
There are several advantages to using one of the types of business loans that use interest rates, as opposed to a factor rate. These include:

Lower total cost of borrowing: In many cases, interest rates may result in a lower total cost of borrowing over the life of the loan, especially for longerterm loans. This is because interest rates typically have lower rates compared to factor rates, and the interest is calculated based on the outstanding loan balance, which decreases as the loan is repaid. Paying back a loan quickly results in paying less in total interest. When a factor rate is used, you pay the same total amount back whether it takes two months or two years.

More suitable for longterm financing: Interest rates are often a better option for longterm financing needs, like real estate purchases or equipment financing. Since the interest rate is calculated based on the outstanding loan balance, borrowers who need to borrow money for a longer period of time can benefit from a lower interest rate and lower overall borrowing costs.

Builds credit score: Using a loan with an interest rate and making ontime payments can help build a business’s credit score. This can be beneficial in the future, as it can improve a business’s chances of obtaining financing at more favorable terms. Many types of financing that use a factor rate aren’t legally considered loans. While that has its benefits, it also means that repaying an advance amount, for example, won’t boost your credit.
