What is a Business Loan?
A business loan, often called a term loan, is a straightforward transaction. A lender provides you with a fixed amount of money, which you agree to repay over a set period. Repayments are typically made in regular instalments, which include both a portion of the principal amount and interest.
Think of it like a mortgage on a house. You receive the full amount at the start to make a large purchase, and you have a predictable repayment schedule for the entire term of the loan.
Key Features of a Business Loan
- Lump Sum Disbursement: You get all the money at once. This is useful for large, specific expenditures where you know the exact cost upfront.
- Fixed Repayment Schedule: You pay a set amount each month for a defined term (e.g., 3, 5, or 10 years). This predictability makes it easier to budget and forecast your cash flow.
- Fixed or Variable Interest: The interest rate can be fixed for the life of the loan, giving you complete certainty over your costs. Some loans may have variable rates that change with the market.
- Specific Purpose: Lenders often want to know the intended use of the funds, as the loan is typically tied to a single, significant investment.
When to Use a Business Loan
Business loans are best suited for large, one-off investments where the cost is known and the return on that investment will be realised over the long term.
Common Use Cases:
- Purchasing Major Assets: This includes buying property, vehicles, or significant pieces of equipment. The long life of the asset matches the long repayment term of the loan.
- Business Expansion: Funding a new location, a major renovation, or acquiring another business. These are singular events with a clear, upfront cost.
- Refinancing Existing Debt: Consolidating multiple debts into a single loan with a more favourable interest rate or repayment term.
Using a term loan for these purposes makes sense because you are financing a long-term asset with long-term debt. The predictable repayment schedule allows you to spread the cost over the useful life of the investment.
What is a Line of Credit?
A line of credit, also known as a revolving credit facility, operates more like a business credit card or overdraft. Instead of receiving a lump sum, you are approved for a maximum credit limit. You can then draw funds from this limit whenever you need them, up to the approved amount.
You only pay interest on the funds you have drawn. As you repay the amount you have used, your available credit is replenished. This means you can borrow and repay repeatedly without having to reapply for a new loan each time.
Key Features of a Line of Credit
- Flexible Access to Funds: You can draw cash as needed for any business purpose. This provides an ongoing source of working capital.
- Interest on Drawn Funds Only: You are not charged interest on the entire credit limit, only on the portion you are actively using. This can make it a more cost-effective option for managing fluctuating cash needs.
- Revolving Nature: Once you repay the funds, your credit limit is restored, and the money becomes available to use again.
- Variable Interest Rates: Rates on lines of credit are almost always variable and are tied to a benchmark rate.
When to Use a Line of Credit
Lines of credit suit short-term, recurring, or unexpected financial needs. They manage changes in your business cash flow cycle. For SMEs dealing with seasonal dips, variable sales, or project-based trading, a revolving credit facility delivers flexibility and speed. To see practical examples or learn how a revolving credit facility works, view our facility guide.
For e-commerce founders balancing inventory and new campaigns, lines of credit can unlock opportunities that boost growth. Soft insights from our funding options for e-commerce and business loans for online retailers share real stories and practical applications. If you need to bridge working capital gaps or cover late-paying invoices during rapid scaling, our working capital loans guide provides a practical view tailored to SMEs.
Common Use Cases:
- Managing Cash Flow Gaps: Bridging the time between paying your suppliers and receiving payment from your customers.
- Seasonal Inventory Purchases: Funding stock purchases ahead of a busy period, like Christmas, with the ability to repay once the sales revenue comes in.
- Unexpected Expenses: Covering costs like equipment repairs or a sudden increase in material prices without disrupting your budget.
- Funding Marketing Campaigns: Paying for advertising spend and repaying the facility as the campaign generates revenue.
- A Financial Safety Net: Having an approved facility in place provides peace of mind. It acts as a buffer, ready to be used instantly when opportunities or challenges arise.
The core benefit of a line of credit is its flexibility. It provides capital that flows with your business, allowing you to react quickly without being locked into a rigid debt structure.
Key Differences at a Glance
Cost Comparison: Understanding What You Pay
The way costs are structured for loans and lines of credit is fundamentally different.
Business Loan Costs
With a term loan, interest is calculated on the full principal amount from the moment it is disbursed. Even if you only use a portion of the funds immediately, you are paying for the entire amount.
- Interest: Typically quoted as a fixed Annual Percentage Rate (APR).
- Origination Fees: Some lenders charge an upfront fee for processing the loan.
- Early Repayment Penalties: Some traditional lenders may charge a fee if you pay the loan off ahead of schedule, as they lose out on future interest payments.
The total cost of a business loan is generally easy to calculate. You know your monthly payments and the total amount you will repay over the life of the loan.
Line of Credit Costs
With a line of credit, you only accrue interest on the amount you withdraw. This can result in significant cost savings if your funding needs are variable.
- Interest: Usually a variable rate applied to your outstanding balance.
- Annual or Monthly Fees: Some providers charge a fee to keep the facility open, even if you are not using it.
- Drawdown Fees: A few lenders may charge a small fee each time you withdraw funds.
The total cost of a line of credit is dependent on your usage. If you use it frequently, your costs will be higher. If you use it sparingly, your costs will be lower. The control is in your hands.
Making the Right Choice: Scenarios for Your Business
A practical way to compare business loans and lines of credit is through real scenarios. You can find direct examples of structuring working capital in our guide to working capital loans. For details on managing ongoing needs using a revolving credit facility, read our facility guide. E-commerce owners and founders in high-growth sectors will find it useful to review our content on e-commerce funding and alternative business loans when considering which product is the best fit for their model.
Scenario 1: The New Workshop
You run a successful joinery business and have found the perfect workshop to buy. The purchase price is £200,000. This is a clear, one-off expense.
- Best Option: Business Loan.
- Why: You need a large, specific sum of money upfront. A term loan provides this. The fixed monthly repayments allow you to budget the cost of the property over many years, just like a residential mortgage. A line of credit would be unsuitable because its purpose is working capital, not fixed asset purchase.
Scenario 2: The Seasonal Retailer
You own an online gift shop. Your busiest period is from October to December. You need to purchase £50,000 worth of extra stock in August to prepare. You expect to sell this stock and receive the revenue by January.
- Best Option: Line of Credit.
- Why: This is a classic working capital challenge. You have a short-term need for funds to cover a specific, revenue-generating activity. You can draw £50,000 from your line of credit in August, sell the goods, and then repay the facility in January. Once repaid, you stop paying interest. A business loan would leave you with repayments for years to come, long after the stock has been sold.
Scenario 3: The Digital Agency
You run a growing digital marketing agency. Your revenue is steady, but you have occasional cash flow lumpiness. A large client might pay 60 days late, or you might need to hire two new staff members to service a new contract before the first invoice is paid.
- Best Option: Line of Credit.
- Why: Your need for funding is unpredictable. You do not need a large lump sum today. You need a flexible safety net. By having a line of credit in place, you can draw funds to cover payroll during a slow payment month or invest in new equipment when needed. It provides the agility to manage growth and uncertainty without taking on unnecessary long-term debt.
How to Apply: Preparation is Key
When you apply for a business loan or a line of credit, each lender will review the financial health of your company. Before starting, review our guide on working capital loans and detailed guide on revolving credit facilities so you know what lenders expect. If your business includes e-commerce or you are exploring different loans, it is practical to check our articles on e-commerce funding and business loan structures for extra examples and real uses.
Typical requirements include:
- Trading History: Most lenders require at least 6 to 12 months of business activity.
- Financial Statements: Be prepared to share bank statements, profit and loss statements, and balance sheets. Modern lenders use Open Banking to make this process seamless.
- Business Plan: For larger loans, a business plan outlining how you will use the funds and generate a return may be required.
- Credit History: Both your business and personal credit scores will be considered.
The best time to apply for funding is when your business is performing well. Securing a line of credit when you do not need it means you will get better terms, and the facility will be ready and waiting for when you do.
