How Business Loans Work: A Complete Guide

Business loans provide capital for growth, equipment, inventory, and operations.

The Five Things a Lender Actually Checks

Most first-time business borrowers assume the loan application is about the business plan. It is not. Commercial underwriters work from a shortlist of measurable risk factors, and a beautifully written plan will not rescue a weak profile.

Trading history. Lenders want to see at least 12 months of trading, and most banks want 24. The reason is simple: a business that has survived one full seasonal cycle has demonstrated it can generate revenue when conditions are not ideal. A business operating for four months has demonstrated nothing yet, regardless of how much revenue is coming in.

Revenue and debt service coverage. This is the number that decides the size of your loan. Debt Service Coverage Ratio (DSCR) is calculated by dividing your annual net operating income by your total annual debt obligations. Most lenders want a DSCR of at least 1.25, meaning the business earns 25% more than it needs to service its existing debt. A retail shop with $120,000 net operating income and $80,000 of existing annual debt payments has a DSCR of 1.50 and will comfortably qualify. The same shop with $95,000 of existing debt payments has a DSCR of 1.26 and sits right at the edge.

Credit profile. Personal and business credit are assessed separately, and in practice your personal score usually carries more weight for a small business. Most banks want a personal FICO of 680 or above. Online lenders will work down to 600, sometimes lower, and price the additional risk into the rate.

Collateral. Secured lending is cheaper lending. If you can pledge equipment, property, or receivables, expect a materially lower rate than an unsecured product. This is the single most controllable lever you have on price.

Industry and concentration risk. A lender will ask what proportion of your revenue comes from your largest customer. Above roughly 25% from one client, some lenders treat the loan as effectively unsecured by the business itself, because losing that client destroys the repayment source.

The Main Loan Structures and What Each One Is For

The mistake most borrowers make is shopping for a rate before deciding on a structure. The structure determines what you can afford to repay, and picking the wrong one is far more expensive than picking a rate 2% higher.

Term loans are a single lump sum repaid on a fixed schedule, usually monthly, over one to ten years. They suit a defined, one-time need: a piece of equipment, a fit-out, an acquisition. Because the repayment is fixed, your cash flow forecast is predictable.

Lines of credit are revolving. You draw what you need, repay it, and draw again, paying interest only on the outstanding balance. They suit working capital that fluctuates with inventory or receivables. A line of credit you never draw still costs you a fee, and drawing it fully and permanently converts it into expensive long-term debt — a common way businesses get into trouble.

SBA 7(a) loans in the United States are partially guaranteed by the government, which shifts risk off the lender's books and gets you a longer term and lower rate than you would otherwise qualify for. The trade-off is documentation: expect a longer approval process and substantially more paperwork. The 504 program is the equivalent for fixed assets such as property and large equipment.

Equipment financing uses the asset itself as collateral. Because the lender can repossess a specific, identifiable, resalable item, rates are among the lowest available for small businesses, and approval is often possible with weaker credit than an unsecured product would allow.

Invoice financing and factoring convert receivables into cash. With factoring, the lender buys the invoice outright at a discount and collects from your customer. With invoice financing, you borrow against the invoice and keep the collection relationship. Factoring is faster and simpler; financing is cheaper and less visible to your customers.

What a Business Loan Actually Costs

The quoted interest rate is the headline number and the least useful one. The figure that matters is the Annual Percentage Rate (APR), which folds fees and the cost of the money into one comparable figure.

Origination fees typically run from 1% to 3% of the loan amount for bank products, and higher for online lenders. On a $200,000 loan, that is $2,000 to $6,000 deducted from what you receive, while the interest is calculated on the full $200,000. If you are quoted a rate and an origination fee, convert both into an APR before you compare offers. Our APR calculator handles this directly.

Some products quote a factor rate rather than an interest rate, which is standard in merchant cash advances. A factor rate of 1.25 on a $100,000 advance means you repay $125,000. That looks like 25%, but the cost depends entirely on how fast you repay. Repaid over nine months, the effective APR is closer to 44%. This is the single most important conversion to make before signing anything.

Worked Example: A $200,000 Expansion Loan

A catering business wants $200,000 to build a second kitchen. Annual revenue is $850,000, net operating income is $180,000, existing debt payments are $45,000 annually, and the owner's personal FICO is 712. The business has traded for six years and owns $90,000 of equipment free and clear.

A bank offers a 7-year term loan at 9.5% APR with a 2% origination fee. The fee is $4,000, so the business receives $196,000 but repays interest on $200,000. The monthly payment works out to $3,301. Over seven years that is $277,284 in total payments, of which $77,284 is interest.

Adding the origination fee, the true cost of borrowing is $81,284 on $196,000 actually received — an effective rate noticeably above the quoted 9.5%. Comparing that against an online lender quoting 12% with no fee, the bank is still cheaper, but the gap is narrower than the headline rates suggest.

Now check the coverage test. Net operating income of $180,000 must service the existing $45,000 plus the new $39,612 annual payment, for a total of $84,612. That gives a DSCR of 2.13, comfortably above the 1.25 threshold. This loan will be approved on coverage grounds; the question is only the price.

Business Loan Types Compared

Risks and Points of Caution

• Personal guarantees. Most small business loans require one. If the business fails, the lender pursues your personal assets. This is the single largest risk in the document and it is usually on page nine.
• Blanket liens. Many loans secure against all business assets, not just the ones you offered. This limits your ability to borrow against those assets elsewhere later.
• Prepayment penalties. Some products charge a fee for early repayment. If your business generates cash faster than expected, this penalty can make an otherwise sensible early payoff uneconomic.
• Variable rates. A rate tied to a benchmark will move. Stress-test the payment at three percentage points above the current rate before you sign.
• Covenants. Loan agreements can require you to maintain minimum financial ratios. Breaching a covenant can let the lender demand immediate repayment even if you have never missed a payment.

What to Do Next

Work through this in order. Each step makes the next one cheaper.

If any step reveals a problem, fix it before applying. A declined application can be visible to other lenders and will not be outweighed by a second attempt at the same lender.

1. Pull your personal credit report and your business credit file. Dispute any error before applying.
2. Calculate your DSCR using last year's net operating income and existing debt payments. If it is below 1.25, reduce existing debt first.
3. Decide the structure before shopping: term loan, line of credit, or asset finance.
4. Get a written offer from at least three lenders, including an SBA option if you are in the United States.
5. Convert every offer into an APR, including all fees, before comparing. Use the APR calculator.
6. Model the new payment against your worst month of the last two years, not your best.
7. Check the loan agreement for personal guarantees, blanket liens, prepayment penalties and covenants.
