Sources of Working Capital Finance: CA Intermediate FM Study Guide

Updated 4 October 2026 · Fact-checked

Sources of working capital finance are the ways a firm funds its current assets. They include spontaneous sources like trade credit and accruals, bank finance like cash credit, overdraft and bill discounting, commercial paper, factoring, and long-term funds for the permanent part. You solve questions by matching the need, cost and duration to the right source.

Understand Sources of Working Capital Finance

Working capital is the money tied up in current assets such as stock, debtors and cash. A firm needs funds to carry these assets while it waits to sell goods and collect cash. The question is where those funds come from.

Sources split by time. Long-term sources (equity, preference shares, debentures, term loans, retained earnings) should fund the permanent working capital, the minimum level of current assets the firm always needs. Short-term sources should fund the temporary (variable) working capital, which rises and falls with seasons and sales.

Short-term sources are of three broad kinds. Spontaneous sources arise naturally from business: trade credit from suppliers, outstanding expenses and advances from customers. Bank finance includes cash credit, overdraft, loans, bill purchase and discounting, and letters of credit. Money market and other instruments include commercial paper, factoring, public deposits and inter-corporate deposits.

In cash credit, the bank sets a limit against security of stock and debtors. You draw and repay as needed, and interest is charged only on the amount used. An overdraft lets you draw beyond the balance in a current account up to a sanctioned limit, and is usually meant for temporary needs. A working capital term loan is a fixed amount repaid on a schedule.

Commercial paper (CP) is an unsecured, short-term promissory note issued at a discount by strong, creditworthy companies. It is usually cheaper than bank credit but is available only to firms with a good rating. Factoring is selling receivables to a factor, who advances cash and may also collect the debts and bear credit risk. Under without recourse factoring the factor bears the bad debt loss. Under with recourse the firm does. Forfaiting is different: it is the discounting of medium-term export receivables without recourse to the exporter, typically backed by a bank guarantee or aval.

The exam tests whether you can name the source, state its feature, and compare costs. Always link the source to the type of need.

Key rules to remember

Annualised cost of discounted instrument (CP, bill discounting): Annualised cost = (Discount ÷ Net proceeds) × (365 ÷ Days); Net proceeds = Face value − Discount. This is simple annualisation. If the question asks for the effective annual rate, use the compounded form: (1 + Discount ÷ Net proceeds)^(365 ÷ Days) − 1.
Cost of trade credit (cash discount foregone): Cost = [d ÷ (100 − d)] × [365 ÷ (Credit period − Discount period)]; d is the cash discount percentage. Use 360 if the question says so.
Factoring advance: Advance = Receivables − Factor reserve − Factoring commission; Interest = Advance × Rate × (Period ÷ 365); Net cash received = Advance − Interest; Interest is charged on the advance, not on receivables, and is usually deducted upfront when the advance is paid. Reserve is returned to the firm when the debts are collected.
Matching principle: Permanent working capital ← long-term funds; Temporary working capital ← short-term funds; A conservative policy uses more long-term funds. An aggressive policy uses more short-term funds.
Cost of factoring (net): Net cost = (Commission + Interest − Savings) ÷ Advance, annualised; Savings include credit department cost saved and bad debts avoided under without recourse.

How to solve Sources of Working Capital Finance questions

Use this method for both theory and numerical questions on sources of working capital finance.

1Read what the question asks: list, explain, compare, or compute cost.
2Classify the need as permanent or temporary and note the period involved.
3Name the suitable sources and group them as spontaneous, bank finance or instruments.
4For each source, state the main feature, security needed, who can use it and the pros and cons.
5For a numerical question, write the cost formula first, then fill in the figures with days and base clearly shown.
6Compute the cost on net proceeds or advance actually received, not on face value.
7Compare options on cost and risk and give a clear recommendation in one line.

Quickest way: Match need, then cost

When to use it: Use this under time pressure, in MCQs and in short written answers.

MCQ: spot the key word. Unsecured and discount means commercial paper. Limit with fluctuating balance means cash credit. Export and medium-term means forfaiting. Collection and credit risk services mean factoring.
MCQ: for cost questions, use discount ÷ net proceeds × 365 ÷ days and test the options quickly.
Written: use a two-part format of a short definition followed by features, then a one-line comparison.
Written numerical: show formula, substitution, answer with the unit (percent per annum) so you earn step marks.
For comparison questions, use bullets with headings such as Recourse, Risk, Cost, Use.

Common mistakes in Sources of Working Capital Finance

Calculating CP or discounting cost on face value instead of net proceeds.
The discount is quoted on face value, so students divide by it.
Fix: Divide the discount by the amount actually received, which is face value less discount.
Confusing factoring with forfaiting.
Both involve selling receivables without much explanation of the difference.
Fix: Remember forfaiting is for medium-term export receivables, without recourse to the exporter, typically backed by a bank guarantee or aval. Factoring is mostly short-term, domestic or export, with or without recourse.
Treating cash credit and overdraft as identical.
Both allow drawing up to a limit.
Fix: Cash credit is secured on current assets and is for regular working capital. Overdraft is on a current account and is usually for temporary needs.
Using 365 days when the question says 360, or the reverse.
Students apply a default without checking.
Fix: Underline the day-count stated in the question and use it throughout.
Funding permanent working capital with short-term sources and calling it safe.
Short-term funds look cheaper.
Fix: State that this is an aggressive policy: cheaper but with higher refinancing risk.
Ignoring savings from factoring when finding net cost.
Students stop at commission and interest.
Fix: Deduct administration cost saved and bad debts avoided before computing net cost.

Worked examples

Example 1

A company issues commercial paper of face value ₹1,00,000 for 90 days at a discount of ₹2,500. Find (a) the annualised cost using simple annualisation and a 365-day year, and (b) the effective annual rate using compounding. Give answers to two decimals.

Show the solution

Net proceeds = ₹1,00,000 − ₹2,500 = ₹97,500.
Cost for 90 days = 2,500 ÷ 97,500 = 2.5641%.
(a) Simple annualisation: 2.5641% × (365 ÷ 90) = 2.5641% × 4.0556.
2.5641 × 4.0556 = 10.40 (approximately).
(b) Effective annual rate: (1.025641)^(365 ÷ 90) − 1 = (1.025641)^4.0556 − 1.
(1.025641)^4.0556 = 1.1081 (approximately), so the effective rate is about 10.81%.

Answer: The annualised (simple) cost is about 10.40% per annum. The effective annual rate, with compounding, is about 10.81% per annum.

Example 2

Supplier terms are 2/10 net 40. Find the annual cost of not taking the cash discount, using a 365-day year and simple annualisation. Should the firm forgo the discount if its bank overdraft costs 18% per annum?

Show the solution

Discount d = 2%. Cost for the extra period = 2 ÷ 98 = 2.0408%.
Extra credit days = 40 − 10 = 30.
Annualise: 2.0408% × (365 ÷ 30) = 2.0408% × 12.1667.
2.0408 × 12.1667 = 24.83% (approximately).
Compare: 24.83% is higher than the 18% overdraft cost.
So it is cheaper to borrow from the bank and take the discount.

Answer: Cost of forgoing the discount is about 24.83% per annum. The firm should take the discount and finance the payment through the 18% overdraft.

Exam tips

Expect a theory question asking you to list and explain sources, often with a comparison such as factoring versus forfaiting. Use a tabular-style bullet comparison with clear headings.
Numerical questions usually ask for cost of CP, trade credit or factoring. Always show the formula and the day-count used.
In recommendation questions, finish with a clear decision and one reason based on cost.
Link each source to permanent or temporary need whenever the question mentions a financing policy.

Sources of Working Capital Finance: frequently asked questions

What is the difference between factoring and forfaiting?

Factoring deals mainly with short-term receivables and may be with or without recourse. Forfaiting deals with medium-term export receivables and is without recourse to the exporter, typically backed by a bank guarantee or aval. Factoring often includes collection and ledger services, while forfaiting is purely finance.

What is the difference between cash credit and overdraft?

Cash credit is a sanctioned limit secured against stock and debtors, used for regular working capital needs. Overdraft is a facility on a current account to draw beyond the balance, usually for short, temporary needs. In both, interest is charged only on the amount used.

Who can issue commercial paper?

Commercial paper is issued by companies with strong credit ratings and adequate net worth, subject to regulatory conditions. It is unsecured and sold at a discount to face value. For the exam, remember it is short-term, unsecured and cheaper than bank credit for good issuers.

Which sources should fund permanent working capital?

Long-term sources such as equity, preference shares, debentures and term loans should fund permanent working capital. Short-term sources should fund the temporary or seasonal part. This is the matching or hedging approach.
