Raising Money From Outside the Business
There are nine external sources on the syllabus and students try to memorise nine separate lists. Do not. They fall into three groups, and once you see the groups you can work out the advantages of any of them from first principles.
📚 What you need to know
External finance comes from outside: lenders, investors, suppliers or the public.
Borrow it: loans, mortgages, overdrafts. You repay with interest, and secured lending puts assets at risk.
Sell a share of the business: share capital, business angels, equity crowdfunding. No repayment, but you give up some control and some future profit.
Delay or rent instead of buying: trade credit and leasing. No large payment up front.
Overdrafts are short-term and flexible; interest is charged only when overdrawn, and the bank can call it in.
Trade credit is usually interest-free, typically 30 to 90 days.
Microfinance and crowdfunding serve firms that banks turn down; the amounts are usually small.
Three groups, not nine lists
If you remember one line from this page, make it the teal one. It works as evaluation in almost any finance question.
Borrowing
Bank loans and mortgages
A fixed sum, repaid in instalments over an agreed period with interest. Secured loans are backed by an asset, so the rate is lower — but the lender can take that asset if repayments stop. A mortgage is simply a long-term secured loan used to buy land or property, usually over many years.
Interest may be fixed (same rate all the way through, easier to plan) or variable (moves with the market, so repayments can rise).
Repayments are a fixed cost that must be met whether sales are good or bad.
The owner keeps full control, because a lender has no vote in the business.
Overdrafts
An agreement with the bank to spend more than is in the account, up to an agreed limit. Interest is charged only on the amount actually overdrawn, and only while overdrawn. That makes it the natural tool for short gaps in cash flow — and a very expensive way to fund anything long term.
If the line never came back above zero, an overdraft would be the wrong answer. That business needs a loan or new investment, not a bigger limit.
The overdraft danger: the bank can “call it in” and demand repayment at short notice if it starts to worry. A firm relying on an overdraft for everyday survival is one phone call from a crisis.
Selling a share of the business
Share capital
A limited company raises money by selling shares — through a flotation (first sale to the public) or a rights issue (offering new shares to existing shareholders, usually at a discount). Shareholders own part of the company, receive dividends when they are declared, and vote at the Annual General Meeting.
Good: huge sums can be raised, and none of it has to be repaid.
Bad: ownership is diluted, profits are shared forever, flotation costs are high, and the original owners can lose control of decisions.
Business angels
Wealthy individuals who invest their own money in start-ups and growing firms in exchange for a stake. They accept more risk than a bank and often bring experience and contacts with them. The hard part is finding the right one, which usually depends on networking, and they will expect a say in decisions.
Crowdfunding
Many small investors back a project through an online platform. It needs a persuasive plan because thousands of projects compete for attention, and backers are often attracted by early access or a sample of the product. It doubles as free marketing, but a failed campaign is public.
Delaying and renting
Trade credit
The supplier delivers stock now and is paid 30 to 90 days later. It is normally interest-free, which makes it one of the cheapest sources there is. Large firms can negotiate longer terms; new businesses with no trading record often cannot get it at all.
Leasing
Renting the asset instead of buying it. Regular payments, no large sum up front, and the leasing company usually handles maintenance and repairs. The business never owns the asset, and over many years leasing costs more than buying would have done.
Microfinance
Small lenders providing finance to people and businesses that no bank would touch. Few formalities, but the amounts available are very limited. It matters most in low-income economies and for very small enterprises.

Worked examples
WORKED EXAMPLE 1
The real cost of a loan [4 marks]
A firm borrows $60,000 over 5 years. Interest is charged at 8% a year on the amount borrowed. Calculate the total repaid and the monthly repayment.
Step 1: interest for one year8% of $60,000 = 0.08 × 60,000 = $4,800Step 2: interest over five years$4,800 × 5 = $24,000Step 3: total repaid$60,000 + $24,000 = $84,000Step 4: monthly repayment over 60 months$84,000 ÷ 60 = $1,400$84,000 in total; $1,400 a monththen make the business point: $1,400 is now a fixed cost every month, good months and bad — that is what “interest is not the only cost of borrowing” means
WORKED EXAMPLE 2
Loan or share capital? [10 marks]
Marisol owns 100% of a private limited company. She needs $500,000 to open a second site. Her bank offers a secured loan against the existing premises. An investor offers $500,000 for a 30% stake. Evaluate the two options.
Step 1: name the trade-offLoan = keep control, take on risk. Shares = share control, remove risk.Step 2: the case for the loan
She keeps 100% of the company and 100% of future profits. Interest is a known, planned cost.
Step 3: the case against the loan
The premises are security. If the second site fails, she could lose the first one too.
Step 4: the case for the investor
Nothing to repay if the site struggles, and an experienced investor may bring useful contacts. But 30% of every future year’s profit is gone permanently, and Marisol now has to consult someone.
It depends on how certain the second site isstrong finish: if the new site is a proven format in a similar area, borrow; if it is a risky new market, share the risk with the investor
💡 Exam tip
Check the legal structure first. Only limited companies can sell shares. A sole trader cannot, no matter how good the idea is.
Match the length of the finance to the length of the need. Long asset, long finance.
Say secured when you mean it. “The bank can take the building” is a real evaluation point.
For any equity source, state exactly what is given up: a share of profit, a share of votes, or both.
Remember availability. Start-ups struggle to get trade credit or bank loans because there is no trading record.
Mention gearing if the firm already has a lot of debt — lenders may simply refuse.
⚠ Common mix-up
Overdraft treated as a loan. An overdraft is short term, flexible, and can be withdrawn by the bank.
Shares treated as debt. Share capital is never repaid; that is the whole point of it.
“Trade credit is free money.” Only if paid on time. Late payment can end the supply relationship.
Leasing called buying. The business never owns a leased asset, so it cannot be sold or used as security.
Assuming any firm can raise share capital. Sole traders and partnerships cannot issue shares.
Recommending a source with no reason. Say why this source suits this purpose, this size and this business.
