A line of credit charges interest on the drawn balance only, and paid-down room can be drawn again. This page covers an electrical contractor's supply account, store payroll at a gas station, a limit increase, line fees, a lumber statement and daily interest at a repair shop. Partners set every limit and rate.

Business lines of credit for a Madison County, KY electrical contractor's supply-house purchases
Electrical contractors counted 12 employer establishments in Madison County, KY in 2023, and 8 of them had fewer than five employees (County Business Patterns, NAICS 238210). Wire, breakers and conduit are bought job by job, which is the pattern a revolving line is built around.
Illustration only, invented figures: the contractor has a $40,000 line. In this invented example it draws $8,200 for wire and breakers on day 3, draws $5,600 for conduit and boxes on day 15, and pays $9,000 back on day 22 when a job pays.
| Day | Activity | Balance drawn | Room left |
|---|---|---|---|
| 3 | Draw for wire and breakers | $8,200 | $31,800 |
| 15 | Draw for conduit and boxes | $13,800 | $26,200 |
| 22 | Pay-down after a job pays | $4,800 | $35,200 |
Interest in the invented month runs only on the drawn balance from day to day, not on the full limit. A partner may also set a minimum payment, a renewal date and fees, which belong in any comparison.
Is a line of credit worth it? Store payroll at a Madison County, KY gas station, priced with and without draws
ZIP 40475 held 39 gasoline station locations with paid employees in 2023 (ZIP Code Business Patterns, NAICS 4471). Store payroll at a station lands every two weeks whether or not the store's sales have caught up, and the gap can be short.
Illustration only, invented figures: the owner compares a $25,000 line at a 13.25% annual rate with a $25,000 term loan at a 12.1% annual rate over 12 months. In this invented example the line is drawn three times for payroll and each draw is repaid within a few weeks.
| Draw | Days outstanding | Interest at 13.25% |
|---|---|---|
| $9,600 | 21 | $73.18 |
| $7,200 | 18 | $47.05 |
| $8,400 | 24 | $73.18 |
The three invented draws cost $193.41 in interest. The invented term loan, by contrast, carries $1,668.68 of interest over its 12 payments of $2,222.39, because the whole amount is owed from day one. For short, repeating gaps the line is the smaller cost in this example; for a one-time cost paid off over a year, a term loan can make more sense. Line fees change the answer and belong in the comparison.
How to increase a line of credit: a Madison County, KY sit-down restaurant asking for a higher limit at renewal
Only 24.6% of the accommodation and food services locations with paid employees in ZIP 40475 had fewer than five employees in 2023 (ZIP Code Business Patterns, NAICS 72). A dining room with a larger staff can outgrow the limit it started with.
A limit increase is a new review. The partner that holds the line may look at recent bank statements, how the line has been used, whether draws were paid down as agreed and how revenue has moved since the line opened. Asking near the renewal date lets that review happen once.
Illustration only, invented figures: a restaurant with a $30,000 line that has been drawn close to the top three times can ask for $45,000 and explain what the extra room is for, such as a larger food order before a catering contract. The partner decides the new limit, and it may keep the old one.
Business line of credit lenders: draw fees, unused-line fees and renewal terms a Madison County, KY quick-service restaurant can ask about
Limited-service restaurants in Madison County, KY carried an annual payroll of $33.2 million in 2023 (County Business Patterns, NAICS 722513). For a kitchen with wages on that scale, the cost of a line is more than its rate.
Illustration only, invented figures: in this invented example a 1.5% draw fee on a $10,000 draw costs $150, and a 0.25% fee on the $40,000 left unused on a $50,000 line costs $100 for the period it applies to. Neither figure describes what any partner charges; they show why fees belong next to the rate.
- Is there a fee each time money is drawn?
- Is there a charge on the part of the limit left unused?
- When does the line renew, and is there a renewal fee?
- Is there a minimum payment, and how is it worked out?
- Can the line be paused or closed, and on what notice?
Builder line of credit in Richmond, KY: carrying a lumber yard statement until the customer pays
Building permits in Madison County, KY authorized 813 new privately owned housing units during 2025 (Census Building Permits Survey). A home builder buying lumber for that kind of volume can use a line of credit for supplier accounts and wages; loans that pay for building the houses are construction lending, which this site does not arrange.
Illustration only, invented figures: a lumber yard statement of $23,030 comes due, and the builder's own customer is set to pay 50 days later. In this invented example the builder draws the $23,030 on a line at a 12.9% annual rate and pays it back after 50 days.
The invented draw costs $406.97 in interest, figured daily on a 365-day year, and each day the customer pays late adds $8.14 more in this invented example, so the draw is worth setting against any late charge on the statement.
How interest builds on a business line of credit: thirty days of draws at a Madison County, KY auto repair shop
ZIP 40475 held 30 automotive repair and maintenance locations with paid employees in 2023 (ZIP Code Business Patterns, NAICS 8111). A shop drawing for parts and paying down as cars leave the bays sees its balance change several times a month.
Illustration only, invented figures: in this invented example the shop draws $6,000 on day 1 and $4,500 on day 12, then pays $5,000 back on day 20, on a line at a 13.4% annual rate charged daily (the annual rate divided by 365).
| Days | Balance drawn | Interest |
|---|---|---|
| 11 days | $6,000 | $24.23 |
| 8 days | $10,500 | $30.84 |
| 11 days | $5,500 | $22.21 |
The invented month costs $77.28 in interest. The invented pay-down on day 20 cut the balance to $5,500 for the last 11 days, which is the whole point of a revolving line: interest follows the balance, and the balance follows the bills.
Line draws also come up in the articles: setting up a revolving line with a hearing clinic's first month, a grounds contract that pays after month end, technician payroll while warranty claims are paid, a new operatory's first visits and costs that return every month.
