Sources of Corporate Finance: Equity, Debt and Hybrid Finance

Updated 11 October 2026 · Fact-checked

Companies raise money from internal sources (retained profits, asset sales) or external sources: equity (ordinary shares), debt (loans, bonds, debentures) and hybrids (preference shares, convertibles). To answer exam questions, compare each source on cost, risk, control, tax treatment, flexibility and availability for the company in the question.

Understand Sources of Corporate Finance

A company needs money to start, to grow and to replace assets. It can get that money in three broad ways: from its own profits, from its owners, or from lenders. Every source has a price and a set of risks. Your job in the exam is to match the source to the situation.

Internal finance means money the company already generates. The main item is retained profit: profit not paid out as dividends. Others are working capital release (collecting debtors faster, holding less stock) and sale of surplus assets. Internal funds need no issue costs and no new investors. But the amount is limited, and shareholders lose the dividend they could have had.

Equity finance is money from ordinary shareholders, either through a new share issue or through retained profit. Shareholders are the owners. They get dividends only if the directors declare them, and they rank last if the company is wound up. So equity is the riskiest for the investor, and it has the highest required return. For the company, equity has no compulsory payments and no repayment date. It also lowers gearing. The costs are high: dividends are paid from after-tax profit, issue costs can be large, and new shares dilute control and existing holders' share of profit.

Debt finance is borrowing: bank loans, bonds, debentures and loan stock. The company must pay interest and repay the capital on time. Lenders rank ahead of shareholders, and secured debt has a claim on specific assets. This makes debt less risky for the lender, so it usually has a lower required return. Interest is normally tax deductible, which makes it cheaper still for the company. The risk for the company is financial distress: if it cannot pay, lenders can enforce their claim. Loan agreements may also include covenants that limit what the company can do.

Hybrid finance has features of both. Preference shares pay a fixed dividend and rank ahead of ordinary shares but behind debt. Convertible bonds pay interest and can be exchanged for shares later, so the coupon is usually lower than on plain debt. Warrants give the right to buy shares at a set price. Leasing gives use of an asset without buying it outright. Hybrids let a company tailor cost, risk and control to its needs.

Key rules to remember

Gearing (debt-to-equity): Gearing = Debt ÷ Equity; One common form. Some definitions use Debt ÷ (Debt + Equity). State the definition you use.
Interest tax shield: Tax saved = Interest × Corporate tax rate; Applies when interest is tax deductible and the company has taxable profit to set it against.
After-tax cost of debt (simple, irredeemable): Kd (after tax) = Interest rate × (1 − tax rate); Applies to debt valued at its par value. For market-valued debt, use the yield instead.
Retained profit: Retained profit = Profit after tax − Dividends; This is the main internal source of long-term finance.
Interest cover: Interest cover = Profit before interest and tax ÷ Interest; A lower value means higher risk that debt cannot be serviced.
Ranking on winding up: Secured creditors > Unsecured creditors > Preference shareholders > Ordinary shareholders; A general order. Exact priority depends on the law and the terms of each instrument. Higher rank means lower risk and lower required return.

How to solve Sources of Corporate Finance questions

Use this method for any question that asks you to choose, compare or advise on sources of finance.

1Read the scenario and note the amount needed, the purpose, the time horizon and the type of company (listed, unlisted, growing, mature).
2List the sources that are realistically available. A small unlisted firm cannot easily issue shares to the public.
3For each source, state the cost to the company: required return, issue costs and tax treatment.
4State the risk to the company: fixed payments, repayment date, covenants, security demanded and effect on gearing.
5State the effect on control and ownership, such as dilution of voting rights or lender restrictions.
6Match the source to the purpose. Long-term assets suit long-term finance; short-term needs suit short-term finance.
7Give a clear recommendation, often a mix, and name the main risk of it.
8If numbers are given, calculate gearing, interest cover or cost, and use the results in your argument.

Quickest way: Cost, Risk, Control, Fit

When to use it: Use this for MCQs and for short written parts when time is tight.

Cost: which source is cheapest after tax? Debt is usually cheaper than equity.
Risk: which source forces fixed payments? Debt does. Equity does not.
Control: which source dilutes ownership? New equity does. Debt does not, though covenants may restrict.
Fit: does the term of the finance match the life of the asset and the type of company?
Pick the answer that fits all four. Hybrids sit between debt and equity on each point.

Common mistakes in Sources of Corporate Finance

Saying retained profit is free finance.
No cash changes hands with outsiders, so it looks costless.
Fix: State that shareholders expect a return on retained funds. Its cost is the cost of equity, though it avoids issue costs.
Saying debt is always better because it is cheaper.
Students focus on the lower required return and the tax shield.
Fix: Add the risk side: fixed payments, possible distress, covenants and security. Higher gearing raises the risk to shareholders.
Treating preference shares as debt in every respect.
They pay a fixed dividend, like interest.
Fix: Note that preference dividends are paid from after-tax profit, are usually not tax deductible, and may be skipped (subject to the terms), unlike interest.
Ignoring the type of company in the question.
Students write a general list of pros and cons.
Fix: Tie every point to the scenario. A start-up, a listed firm and a mature firm have different options.
Mismatching the term of finance and the asset.
Students forget to compare the repayment date with the asset's useful life.
Fix: Use long-term finance for long-term assets and short-term finance for working capital. State this link explicitly.
Forgetting issue costs and dilution for new equity.
The focus stays on dividends as the only cost.
Fix: Always mention issue costs, dilution of control and dilution of earnings per share when discussing new shares.

Worked examples

Example 1

A company has profit before interest and tax of ₹80,00,000. It has ₹5,00,00,000 of 8% debentures and ₹10,00,00,000 of equity (book value). The tax rate is 25%. Calculate (a) annual interest, (b) interest cover, (c) the tax saved by the interest, and (d) gearing as Debt ÷ Equity.

Show the solution

(a) Interest = 8% × ₹5,00,00,000 = ₹40,00,000.
(b) Interest cover = ₹80,00,000 ÷ ₹40,00,000 = 2.0 times.
(c) Tax saved = ₹40,00,000 × 25% = ₹10,00,000, since there is enough profit to absorb the deduction.
(d) Gearing = ₹5,00,00,000 ÷ ₹10,00,00,000 = 0.5, or 50%.

Answer: Interest ₹40,00,000; interest cover 2.0 times; tax saved ₹10,00,000; gearing 50%. A cover of 2.0 means profit could fall by half before interest is not covered, so the debt risk is moderate.

Example 2

A listed manufacturing company needs ₹20 crore to build a new plant that will last 20 years. Compare financing it by a rights issue of ordinary shares with a 15-year secured bond. Recommend one.

Show the solution

Rights issue: no fixed payments and no repayment date, and it lowers gearing. But the required return is high, issue costs apply, and existing shareholders must put in more money or be diluted.
Secured bond: lower required return, and interest is tax deductible. But interest and capital are fixed obligations, the plant may be pledged as security, and covenants may limit the company.
Fit: the plant lasts 20 years, so long-term finance suits. The bond matures in 15 years, so refinancing may be needed at the end.
Judgement: the answer depends on current gearing and earnings stability. If cash flows from the plant are steady and gearing is low, the bond is cheaper. If gearing is already high, equity reduces risk.

Answer: If existing gearing is low and cash flows are stable, recommend the secured bond because it is cheaper after tax and keeps control. If gearing is already high or earnings are volatile, recommend the rights issue, or a mix, to avoid distress risk.

Exam tips

Structure every comparison under cost, risk, control and fit. It earns marks even when you are unsure of the details.
Use the scenario. Name the company type, the purpose and the time horizon in your answer.
Show a short calculation when numbers are given. Gearing and interest cover are common and quick to compute.
In MCQs, watch for words like always and never. Few statements about finance are true in every case.
Discuss hybrids by saying which features of debt and which of equity they carry.

Sources of Corporate Finance: frequently asked questions

What is the main difference between equity and debt finance?

Equity gives shareholders ownership and a share of profit, with no fixed payment or repayment date. Debt is a loan with fixed interest and a repayment date, and lenders rank ahead of shareholders if the company fails. This is why equity costs more but carries less risk of distress.

Why is debt usually cheaper than equity for a company?

Lenders face lower risk because they have a fixed claim and rank ahead of shareholders, so they accept a lower return. Interest is also normally tax deductible. Both effects lower the cost of debt to the company.

What counts as hybrid finance?

Hybrid finance combines features of debt and equity. Common examples are preference shares, convertible bonds and warrants. Leasing is often discussed alongside them as another flexible method.

Is retained profit an internal or external source?

It is internal. The company keeps profit instead of paying it out. It avoids issue costs, but shareholders still expect a return on the money kept.
