How Interest Is Calculated on Revolving Credit
To use a revolving loan as intended, you should be clear on how it works — and especially on how revolving interest is determined. With a revolving line of credit, interest is calculated based on your principal balance amount. You only pay interest on funds drawn.
See example below to learn how interest is calculated:
Determining Principal Balance
Interest on a revolving loan is calculated based on the amount of the principal balance that is outstanding for the prior month. You'll never pay interest on interest; you'll only pay interest on the money you've used. Here's an example that assumes a monthly repayment schedule:
- June 1 – 5: When your balance is $0, you pay no interest for those five days.
- June 6: You borrow $10,000.
- June 10: You voluntarily pay back $5,000 towards your principle.
- July 1: Pay interest on $10,000 for five days, and on $5,000 for the remaining 21 days in the month.
Interest on a revolving line of credit is typically calculated on a basis of actual days over a 360-day year. At Headway Capital, we use a 365-day year, as used in the example below. The formula to calculate interest on a revolving loan is the balance multiplied by the interest rate, multiplied by the number of days in a given month, divided by 365. In a month with 31 days, you'll multiply by 31 before dividing by 365. In a month with 30 days, you'll multiply by 30 before dividing by 365.
Let's say your principal balance is $10,000 from June 1 - 15 and your interest rate is 40%. Multiply 10,000 by 0.4, then multiply by 15 (days) and divide by 365. The interest fee for those 15 days is $164.38.
Say you paid the loan down to $3,000 on June 16. Now multiply 3,000 by 0.4, then multiply by 15 (days) and divide by 365. Your interest fee for the remainder of the month is $49.32. Add both figures together and you get $213.70, the total interest due for the month of June.
Why Choose a Revolving Line of Credit
Revolving lines of credit can be used for any business expense. Many also offer flexible repayment terms, while business term loans require you to repay a specific amount at specific intervals of time.
Traditional term loans provide a lump sum, and you pay interest based on that total lump amount. With a revolving line of credit, you have an available credit limit. This lets you borrow what you need, when you need it, and pay interest only on the amount you borrow, not the total credit limit amount.
