Drawing Power Calculation: Formula, Margins, Stock Statements and the RBI Rules Behind Them

A cash credit limit is a ceiling, not an entitlement. What a borrower can actually draw on any given day is the drawing power (DP), and DP depends on something the bank cannot see directly: the value of the borrower’s stock and receivables.

That gap between sanctioned limit and verified security is where working capital lending goes wrong. Inflated stock statements, ageing debtors counted as current, and unpaid stock funded twice are among the most common routes to a cash credit account becoming irregular and then non-performing.

This guide explains how drawing power is calculated, how the margin structure works, what RBI’s asset classification rules say about stale DP, and how lenders can test a stock statement against independent data.

What Drawing Power Is

Drawing power is the amount a borrower may draw from a cash credit or overdraft account at a given time. It is the lower of two figures: the sanctioned limit, and the value of eligible current assets after margins.

If a trader has a ₹2 crore cash credit limit but eligible stock and debtors support only ₹1.4 crore after margins, DP is ₹1.4 crore. Drawing beyond that is an irregularity even though it is within the sanctioned limit.

The sanctioned limit itself comes from the working capital assessment, often built on CMA data. DP is the ongoing, month-by-month control that keeps actual borrowing tied to actual security.

The Drawing Power Formula

The standard calculation:

\text{DP} = (\text{Stock} – \text{Sundry creditors for goods}) \times (1 – m_s) + \text{Eligible debtors} \times (1 – m_d)

Where m_s is the margin on stock and m_d is the margin on debtors, both set in the sanction terms.

Three adjustments make or break the calculation:

• Unpaid stock is deducted. Stock bought on credit belongs, in economic terms, to the supplier. Sundry creditors for goods are subtracted so the bank does not finance stock that has not been paid for.
• Only eligible debtors count. Most sanctions exclude receivables older than 90 days; some allow 120 or 180 days for specific sectors. Debts due from related parties or group concerns are normally excluded.
• Margins differ by asset. Typical margins are 25 percent on stock and 40 percent on debtors, reflecting the higher recovery risk of receivables. Actual margins are set per sanction.

A Worked DP Calculation

A Ludhiana hosiery manufacturer submits its month-end stock statement for a ₹3 crore cash credit limit.

Item (₹ lakh)	Amount	Treatment
Raw material, WIP and finished goods	260	Gross stock
Sundry creditors for goods	70	Deducted
Paid stock	190	25% margin → 142.5
Total debtors	180
Debtors older than 90 days	45	Excluded
Eligible debtors	135	40% margin → 81
Drawing power		223.5

DP is ₹2.235 crore, well below the ₹3 crore sanctioned limit. If the account shows an outstanding balance of ₹2.6 crore, it is overdrawn against DP by ₹36.5 lakh, even though it looks comfortable against the limit.

Stock Statements and Their Weak Points

DP is only as reliable as the stock statement behind it. Borrowers typically submit monthly or quarterly statements listing inventory by category and debtors by age. Common weaknesses:

• Valuation above cost. Stock should be valued at the lower of cost or realisable value. Finished goods valued at selling price inflate DP by the margin.
• Obsolete or slow-moving stock. Inventory that has not moved in a year still appears in the total unless the lender asks for ageing.
• Debtor ageing that resets. Part payments or credit notes can make old debts appear new.
• Double financing. The same stock may be pledged to another lender or covered by supplier credit that is not disclosed.
• Month-end timing. Stock can be inflated at month-end by bringing in goods on approval or delaying dispatches.

This is why many banks require periodic stock audits by external auditors above a policy threshold, often set around ₹5 crore of working capital exposure, alongside unannounced inspections.

RBI Rules That Make DP a Classification Issue

Drawing power is not only a credit control; it is tied directly to asset classification under RBI’s income recognition and asset classification (IRAC) norms.

• A cash credit or overdraft account is treated as out of order if the outstanding balance remains continuously above the sanctioned limit or drawing power for 90 days. An out-of-order account can be classified as a non-performing asset.
• Drawings permitted against DP computed from stock statements older than three months are deemed irregular. A borrower who stops submitting stock statements is on a clock toward NPA classification even if interest is being serviced.

For lenders, this means DP tracking is a portfolio quality issue, not paperwork. Stale DP data creates classification risk and, if missed, a provisioning surprise. It is also a core input for delinquency bucket management.

Checking DP Against Bank and GST Data

A stock statement is self-declared. Three independent checks catch most inflation.

Purchases vs GST inward supplies

If the stock statement shows inventory rising by ₹60 lakh in a quarter, purchases in that quarter should be visible in GSTR-2B inward supplies. A rising stock figure with flat purchases implies either valuation changes or a statement that does not match reality. The GSTR-2B analysis for the same months is the quickest test.

Sales vs debtor build-up

Debtors can only grow if sales are made on credit. Compare month-wise GSTR-1 outward supplies with bank collections. If sales are flat and collections steady, a sharp rise in declared debtors does not add up.

Supplier payments vs creditors

Outward payments to suppliers in the bank statement show whether sundry creditors are being paid. A borrower declaring low creditors while bank statements show irregular or delayed supplier payments may be understating creditors to increase DP.

FinEye’s GST Analyser provides month-wise inward and outward supplies and filing status, while the Bank Statement Analyser maps collections, supplier payments and cash credit utilisation by day. Together they let a credit or monitoring team test each stock statement against transaction data, rather than relying on the next stock audit.

Key Takeaways

• Drawing power is the lower of the sanctioned limit and eligible current assets after margins.
• Unpaid stock is deducted, debtors beyond the age cut-off are excluded, and different margins apply to stock and debtors.
• An account overdrawn against DP is irregular even if it is within the sanctioned limit.
• Under RBI’s IRAC norms, overdrawing DP for 90 days, or relying on stock statements older than three months, can lead to NPA classification.
• GST inward and outward supplies and bank supplier payments are the fastest independent checks on a stock statement.
• Monthly DP tracking belongs in portfolio monitoring, not only at renewal.

Frequently Asked Questions

Conclusion

Drawing power turns a working capital sanction into a daily discipline. It is also where borrower self-reporting has the most room to drift from reality, because the underlying asset sits in a warehouse the lender rarely sees.

The lenders that manage cash credit portfolios well do not wait for the annual stock audit. They test every stock statement against GST purchases, sales, and bank flows as it arrives, and they treat a widening gap as an early warning rather than a renewal-time discovery.
