Internal and External Sources of Finance (Edexcel 9BS0 2.1.1–2.1.2)
Every plan in Theme 2 needs paying for. This topic covers internal sources — owner's capital, retained profit and sale of assets — and the external menu from overdrafts to share capital and crowdfunding. Exam questions almost always ask you to match the source to the situation.
Internal sources
Owner's capital is the founder's own money invested in the business — often the only option at start-up, signalling commitment to other lenders but limited by personal wealth. Retained profit is profit kept in the business rather than paid out; it is the largest single source of finance for established UK companies because it carries no interest, no dilution and no repayment. Its cost is hidden: shareholders give up dividends, and the money is only there if the business is profitable. Sale of assets turns unused property, machinery or divisions into cash; sale-and-leaseback keeps use of an asset while releasing its value.
- Internal finance is quick and keeps control intact.
- It is limited by past success — loss-makers have no retained profit.
- Selling assets can weaken future capacity if done under pressure.
Greggs funds much of its shop-opening programme from retained profit, supported by 2024 pre-tax profits of around £204 million.
External sources
Edexcel's list: family and friends, banks (loans and overdrafts), peer-to-peer lending, business angels, crowdfunding, other businesses (trade credit, venture partners), plus methods of raising it — loans, share capital, venture capital, overdrafts, leasing, trade credit and grants.
Loans give certainty (fixed repayments) but require security and interest whatever profits do. Overdrafts flex with need but carry high rates and can be withdrawn. Share capital raises large sums with no repayment, at the price of ownership and dividends. Venture capital and angels add expertise alongside money but demand significant equity and influence.
Crowdfunding blends finance and marketing: BrewDog's 'Equity for Punks' rounds raised over £80m from tens of thousands of small shareholders who doubled as loyal customers. Gymshark took the private-equity route instead, selling a 21% stake to General Atlantic in 2020 at a valuation above £1 billion — external equity without a stock-market listing.
Matching the source to the situation
The right source depends on five tests. Amount: overdrafts suit small, short gaps; share issues suit transformational sums. Duration: match the term of finance to the life of the asset — never fund a building with an overdraft. Cost: compare interest against the dividends and control given up with equity. Control: founders who value independence prefer debt or retained profit over equity. Risk: debt magnifies losses because repayments continue in bad years, so firms with volatile revenue should limit borrowing.
Context changes the answer. When Bank of England base rate sat above 4% through most of 2024–25, borrowing was far costlier than in the 2010s, tilting decisions towards retained profit and equity. A loss-making start-up cannot use retained profit and may find banks unwilling, pushing it to angels or crowdfunding.
In exams, always give the situational reason: 'a five-year loan matches the delivery van's useful life' scores; 'a loan because banks lend money' does not.
Key terms
Practice questions
Explain one advantage to an established business of using retained profit to fund expansion. [4 marks]
Model answer guidance: Retained profit carries no interest payments and never has to be repaid, so expansion does not add fixed financial commitments. The owners also keep full control, unlike a share issue which dilutes ownership. Greggs funding new shop openings from its profits — around £204m pre-tax in 2024 — means growth does not depend on lenders' approval. The main limit is that the amount available is capped by past profitability.
Explain one drawback of financing a long-term investment with an overdraft. [4 marks]
Model answer guidance: An overdraft is repayable on demand and charges high interest, so it is designed for short-term cash gaps, not multi-year investment. If the bank withdraws or reduces the facility mid-project, the business faces a funding crisis before the investment earns anything. The interest cost over years would also far exceed a term loan. Matching the duration of finance to the life of the asset avoids this mismatch.
Discuss whether crowdfunding is a suitable way for a consumer brand to raise growth finance. [8 marks]
Model answer guidance: Crowdfunding suits consumer brands because backers become both shareholders and advocates — BrewDog's Equity for Punks raised over £80m while building a community of customer-owners who promoted the beer. It also avoids a single powerful investor. However, campaigns are public: failure to hit a target damages the brand, thousands of small shareholders create administrative and governance burdens, and the sums raised are usually smaller than venture capital or bank lending can offer. It is most suitable when the product excites the public and the business wants marketing value alongside money; a business-to-business firm would gain far less.
Assess whether a fast-growing private company should raise finance by selling an equity stake to an outside investor. [12 marks]
Model answer guidance: Selling equity raises large, repayment-free sums matched to growth risk, and the right investor adds expertise and contacts — Gymshark's 2020 sale of a 21% stake to General Atlantic brought retail-scaling experience along with capital at a valuation above £1bn. Equity also strengthens the balance sheet when borrowing was expensive, as with base rates above 4% across 2024–25. The costs are permanent: dividends and value flow to outsiders, founders accept scrutiny and may lose strategic freedom, and disagreements over exit timing can be corrosive. The judgement should turn on the growth plan: if the opportunity is large, time-limited and beyond debt capacity, diluting ownership to own a smaller share of a much bigger business is rational; if growth can be funded from retained profit, keeping control is usually worth the slower pace.
Evaluate whether internal sources of finance are better than external sources for funding business growth. [20 marks]
Model answer guidance: Internal finance — chiefly retained profit — is cheap, quick and preserves control, which is why profitable firms like Greggs fund expansion largely from their own earnings. It imposes discipline too: growth is paced by real profitability rather than optimism. But internal sources are rationed by the past; they cannot fund transformational moves, and hoarding cash has an opportunity cost when shareholders could reinvest dividends elsewhere. External finance unlocks scale and speed: loans amplify returns when projects out-earn interest, equity shares risk with investors, and options such as leasing and trade credit tune finance to specific needs. Its dangers are gearing risk, dilution and dependence on markets that can close — costly borrowing through 2024–25 showed how conditions shift. The strongest evaluation rejects 'better' in the abstract: internal finance should normally fund routine growth, with external finance reserved for opportunities whose returns clearly exceed its cost, because the real skill is matching source to purpose, amount and risk.
Examiner tips
- Always match duration: short-term needs (stock, cash gaps) to overdrafts and trade credit, long-term assets to loans, equity or retained profit.
- State the control effect of every source you recommend — dilution is the examiner's favourite counter-argument.
- Use interest-rate context in evaluation: borrowing decisions look different with base rate above 4% (2024–25) than near zero.
