Pecking Order Theory of Financing Explained for ACCA FM

Updated 11 October 2026 · Fact-checked

Pecking order theory says firms finance new investment in a set order: retained earnings first, then debt, and new equity last. The order follows cost, effort and the signals sent to investors. In ACCA FM you apply it by ranking sources, then explaining why each ranks where it does.

Understand Pecking Order Theory

Pecking order theory describes how firms choose finance. It does not look for a target gearing ratio. Instead, firms take the easiest and cheapest source first and move down the list only when that source runs out.

The order is: internal funds (retained earnings), then debt, then new equity. Internal funds are first because they cost nothing to raise. There are no issue costs, no need to satisfy lenders or regulators, and no need to explain the project to outsiders.

The main reason for the order is information asymmetry. Managers know more about the firm's prospects than outside investors do. If a firm issues new shares, investors may suspect managers think the shares are overpriced. So the share price may fall on the announcement. Debt sends a weaker signal, because managers who borrow are signalling confidence they can meet fixed payments.

Issue costs add to the argument. Issuing shares or arranging a large debt facility costs money, and equity issues are usually the most expensive. Debt is cheaper to raise and has a tax advantage, since interest is normally tax deductible.

Compare it with trade-off theory. Trade-off theory says there is an optimal gearing level, balancing the tax benefit of debt against the costs of financial distress. Pecking order theory says there is no target. A firm's gearing is simply the result of past funding needs. This helps explain why profitable firms often have low gearing: they fund investment from retained earnings and rarely need to borrow.

Key rules to remember

Pecking order of finance
Retained earnings → Debt → New equity
Use this as a ranking rule, not a calculation. Firms move down only when the previous source is exhausted or insufficient.
Funding gap
External funding needed = Investment required − Internal funds available
If the gap is zero or negative, the theory predicts no external finance. If positive, borrow first, then issue shares if needed.

How to solve Pecking Order Theory questions

Use this method for any question asking which finance a firm will choose, or why, under pecking order theory.

  1. 1Identify the amount of finance needed for the investment.
  2. 2Work out the internal funds available, such as retained profits or cash surplus, after dividends.
  3. 3Calculate the funding gap: investment needed minus internal funds. If it is zero or negative, stop. Internal funds are enough.
  4. 4If there is a gap, look at debt capacity. Consider existing gearing, covenants, security available and interest cover.
  5. 5Only if debt is unavailable or too risky, use new equity for the remaining amount.
  6. 6Explain each step using the reasons: issue costs, control, information asymmetry and signalling.
  7. 7If asked to compare, state that trade-off theory targets an optimal gearing level while pecking order theory has no target.

Quickest way: Rank, fill, explain

When to use it: Use this for Section A or OT case questions where you must pick the statement that matches pecking order theory.

  1. Remember the order: retained earnings, debt, new equity.
  2. Reject any option that says the firm aims for a target or optimal gearing. That is trade-off theory.
  3. Reject any option that puts new equity before debt, unless debt capacity is exhausted.
  4. Link the reason to information asymmetry, issue costs and signalling.
  5. In calculation-style questions, fill the need from internal funds, then debt, then equity.

Common mistakes in Pecking Order Theory

  • Putting new equity before debt in the order.

    Students assume equity is safer because it has no fixed payments.

    Fix: Remember the theory is about cost, effort and signals, not risk. Debt is cheaper to raise and sends a weaker negative signal than new shares.

  • Saying pecking order theory gives an optimal gearing ratio.

    It is confused with trade-off theory and the traditional view.

    Fix: State that pecking order has no target gearing. Gearing is the by-product of financing choices over time.

  • Saying retained earnings are free.

    There is no cash payment or issue cost, so they look costless.

    Fix: Say they are cheapest to raise, not costless. Shareholders still expect a return, so they have an opportunity cost, as the cost of equity shows.

  • Forgetting information asymmetry as the main reason.

    Students list only issue costs and give a thin answer.

    Fix: Always include that managers know more than investors, so a share issue may be read as a sign the shares are overvalued.

  • Ignoring dividends when finding internal funds.

    Students use total profit rather than profit retained.

    Fix: Internal funds are profit after tax minus dividends paid, plus any surplus cash. Check the dividend policy in the scenario.

Worked examples

Example 1

Delta Co plans a project costing $8 million. It expects profit after tax of $6 million this year and will pay dividends of $2.5 million. It has no other surplus cash. Its existing debt is low and lenders are willing to lend. Under pecking order theory, how will Delta finance the project?

Show the solution
  1. Internal funds = profit after tax − dividends = $6 million − $2.5 million = $3.5 million.
  2. Funding gap = $8 million − $3.5 million = $4.5 million.
  3. Use internal funds first: $3.5 million.
  4. The gap is $4.5 million. Debt is available, so borrow next.
  5. Debt of $4.5 million covers the gap, so no new equity is needed.

Answer: Delta uses $3.5 million of retained earnings and borrows $4.5 million. It issues no new equity.

Example 2

Explain why a listed company may prefer to finance a new project from retained earnings rather than a rights issue, and how this differs from trade-off theory.

Show the solution
  1. State the order: pecking order theory ranks retained earnings first, debt second and new equity last.
  2. Give cost reasons: retained earnings have no issue costs, while a rights issue involves underwriting and administration costs.
  3. Give the signalling reason: managers know more than investors. A new share issue may suggest the shares are overvalued, so the price may fall.
  4. Add practical points: retained earnings need no outside approval and avoid shareholder dilution, though shareholders still expect a return.
  5. Contrast with trade-off theory: it says firms aim for an optimal gearing level that balances the tax benefit of debt against financial distress costs.
  6. Conclude that pecking order theory sees gearing as the result of funding needs, not a target.

Answer: Retained earnings are cheaper, simpler and send no negative signal. Pecking order theory has no target gearing, whereas trade-off theory aims for an optimal level.

Exam tips

  • In written answers, give at least three reasons for the order: issue costs, information asymmetry and control or dilution.
  • Always contrast with trade-off theory when the question mentions capital structure theories. One clear sentence on the difference earns marks.
  • In an OT case, watch for the word 'target'. A firm with a target gearing ratio is following trade-off thinking, not pecking order.
  • Do the funding gap arithmetic carefully: deduct dividends before finding internal funds.
  • Link your answer to the scenario. Mention the firm's profit, existing debt or growth plans rather than writing only general theory.

Pecking Order Theory: frequently asked questions

What is pecking order theory in ACCA FM?

It says firms prefer to finance investment from retained earnings first, then debt, then new equity. The order reflects issue costs and the signals each source sends to investors. It is part of the capital structure theories in FM.

Why do firms prefer retained earnings to new equity?

Retained earnings have no issue costs and need no outside approval. New equity is expensive to raise and may signal that managers think shares are overvalued. Retained earnings also avoid diluting existing shareholders.

What is the difference between pecking order and trade-off theory?

Trade-off theory says firms aim for an optimal gearing level that balances the tax benefit of debt against distress costs. Pecking order theory says there is no target. Gearing simply results from using internal funds first, then debt, then equity.

Why is debt preferred to new equity?

Debt is cheaper to arrange than a share issue and interest is usually tax deductible. It also sends a weaker negative signal to the market. Managers who borrow show confidence that they can meet the payments.
