Maximum Permissible Bank Finance (MPBF): CCP Credit Appraisal Guide

Working capital assessment sits at the heart of every lending decision, and the Maximum Permissible Bank Finance (MPBF) method remains the single most tested concept for anyone preparing for the Certified Credit Professional certification. Understanding how a bank sizes a borrower's short-term credit need — and how much of that need it is willing to fund — separates a competent credit officer from a mechanical form-filler. This guide walks through the MPBF framework, its origins in the Tandon and Chore Committee recommendations, and how it is applied in practice today under the RBI's liberalised lending environment.

At its core, the Maximum Permissible Bank Finance concept answers one question: given a borrower's current assets and current liabilities, how much working capital gap should the bank finance, and how much should the promoter bring in as margin? Getting this balance right protects the bank against over-lending while ensuring the business has enough liquidity to operate. For CCP aspirants, mastering the two MPBF methods is non-negotiable.

The Working Capital Gap and Its Financing

Every operating business ties up money in inventory and receivables while enjoying credit from its own suppliers. The working capital gap is the difference between current assets required to run the business and the current liabilities (other than bank borrowing) available to fund them. A trader who must hold two months of stock and extend one month of credit to customers, while getting only three weeks of credit from suppliers, has a structural gap that someone must finance.

The classical approach, drawn from the Tandon Committee (1975), held that a portion of this gap must be met by the borrower's own long-term funds — the margin — so that the business is not entirely dependent on volatile bank credit. The remainder becomes the bank's exposure. This margin discipline is why a healthy current ratio matters: it signals that promoters have skin in the game and that short-term assets comfortably exceed short-term obligations. A credit officer who understands the gap can spot a borrower who is quietly using short-term bank money to fund long-term assets — a classic early warning of stress. The Reserve Bank of India's prudential norms, published at rbi.org.in, continue to shape how banks frame these assessments even after formal MPBF ceilings were withdrawn.

Tandon Committee Method I and Method II

The Tandon Committee prescribed two methods for computing the Maximum Permissible Bank Finance, differing only in how much margin the borrower must contribute. Under Method I, the borrower funds 25% of the working capital gap from long-term sources, and the bank finances the remaining 75%. Under Method II, the borrower must fund 25% of the total current assets (not merely the gap), leaving the bank to finance the rest. Method II demands a higher margin and therefore produces a stronger current ratio of roughly 1.33:1.

A simple illustration makes the difference vivid. Suppose current assets are 1,000 and current liabilities other than bank finance are 200. The working capital gap is 800. Under Method I, the margin is 25% of 800 = 200, so MPBF is 600. Under Method II, the margin is 25% of 1,000 = 250, so the bank finances 800 minus 200 (other current liabilities) minus 250 = 350. Method II clearly tightens the leash. Later, the Chore Committee (1979) pushed borrowers progressively toward Method II to strengthen financial discipline. Candidates should be able to compute both quickly, because numerical MPBF questions appear reliably in the exam and in real appraisal notes.

From MPBF to Modern Turnover and Cash-Budget Methods

In 1997 the RBI freed banks to devise their own systems for assessing working capital, and the rigid MPBF ceiling was formally withdrawn. Yet the thinking behind it endures. For smaller units, many banks adopt the Nayak Committee turnover method, which pegs working capital finance at 20% of projected annual turnover, with the borrower expected to contribute a 5% margin. For seasonal or project-linked businesses, the cash budget method — projecting month-by-month inflows and outflows to find the peak deficit — gives a far sharper picture than any ratio.

The practical lesson for a Certified Credit Professional is that no single formula fits every borrower. A software exporter, a sugar mill, and a jewellery retailer each have radically different working capital rhythms, and the credit officer must choose the assessment method that mirrors the underlying business. This is where classroom theory meets judgement. Structured practice through our CAIIB course and mock test bank helps candidates internalise when to reach for MPBF, when for turnover, and when for a full cash budget.

Frequently Asked Questions

Conclusion and Next Steps

The Maximum Permissible Bank Finance framework is more than an exam formula — it is a durable way of thinking about how much short-term credit a business truly needs and how the risk should be shared between promoter and bank. Whether you ultimately use MPBF, the turnover method, or a cash budget, the discipline of measuring the working capital gap and insisting on adequate margin never goes out of date. Ground yourself in the Tandon and Chore Committee logic, practise the numerical computations until they are second nature, and always relate the method to the borrower's real business cycle.
