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 eligible stock and receivables.
That gap between the sanctioned limit and verified security is where working capital lending can go wrong. Inflated stock statements, ageing debtors counted as current, and stock funded twice can cause a cash credit account to become irregular and eventually non-performing.
This guide explains how drawing power is calculated, how the margin structure works, how stale stock statements affect account monitoring, and how lenders can test a stock statement against independent bank and GST data.
What Is Drawing Power?
Drawing power is the amount a borrower may draw from a cash credit or overdraft account at a given point in time.
In simple terms, DP is determined by comparing:
- The sanctioned credit limit
- The value of eligible current assets after applicable deductions and margins
The amount available for drawing is generally the lower of the two.
For example, suppose a borrower has a ₹2 crore cash credit limit, but eligible stock and receivables support only ₹1.4 crore after applying the applicable margins.
The drawing power is ₹1.4 crore.
If the borrower draws ₹1.6 crore, the account is overdrawn against DP even though the outstanding balance is still below the sanctioned ₹2 crore limit.
This distinction matters:
The sanctioned limit defines the facility. Drawing power determines how much can be drawn against the eligible security available at that time.
The sanctioned limit may be based on a working capital assessment such as CMA data. DP is the ongoing control that links actual borrowing to the security available month by month.
Drawing Power Calculation Formula
A simplified drawing power formula is:
DP = (Stock − Sundry Creditors for Goods) × (1 − Stock Margin) + Eligible Debtors × (1 − Debtor Margin)
Where:
- Stock is the eligible inventory reported by the borrower.
- Sundry creditors for goods are unpaid purchases deducted from eligible stock.
- Eligible debtors are receivables that meet the lender's eligibility criteria.
- Stock margin is the margin specified in the sanction terms.
- Debtor margin is the margin specified in the sanction terms.
The exact calculation can vary depending on the lender's sanction terms, facility structure, and credit policy.
Three adjustments are particularly important when calculating DP.
1. Unpaid Stock Is Deducted
Stock purchased on credit is generally adjusted against the corresponding trade creditors.
This prevents the bank from financing inventory that remains funded by suppliers.
For example:
- Gross stock: ₹260 lakh
- Sundry creditors for goods: ₹70 lakh
- Eligible paid stock: ₹190 lakh
If the applicable stock margin is 25%, the financeable stock value becomes:
₹190 lakh × 75% = ₹142.5 lakh
2. Only Eligible Debtors Count
Not every receivable reported by a borrower contributes to drawing power.
Lenders commonly apply an ageing cut-off. Receivables beyond the permitted period may be excluded from the calculation.
Depending on the sanction terms, lenders may also exclude receivables from:
- Related parties
- Group companies
- Promoters or directors
- Other ineligible counterparties
The applicable eligibility rules depend on the lender's policy and sanction conditions.
3. Margins Differ by Asset
Different asset classes can carry different margins.
For example, a sanction may specify:
- 25% margin on stock
- 40% margin on eligible debtors
These are illustrative figures. Actual margins are determined by the lender based on the facility and sanction terms.
The purpose of the margin is to provide a buffer between the reported value of the security and the amount financed by the bank.
Worked Drawing Power Calculation
Consider a Ludhiana hosiery manufacturer with a ₹3 crore cash credit limit.
The borrower submits the following month-end stock statement:
| Item | Amount (₹ lakh) | Treatment |
|---|---|---|
| Raw material, WIP and finished goods | 260 | Gross stock |
| Sundry creditors for goods | 70 | Deducted |
| Eligible paid stock | 190 | 25% margin = ₹142.5 lakh |
| Total debtors | 180 | Reported receivables |
| Debtors older than 90 days | 45 | Excluded |
| Eligible debtors | 135 | 40% margin = ₹81 lakh |
| Drawing power | ₹223.5 lakh |
The calculation is:
Eligible stock
₹260 lakh − ₹70 lakh = ₹190 lakh
Financeable stock
₹190 lakh × 75% = ₹142.5 lakh
Eligible debtors
₹180 lakh − ₹45 lakh = ₹135 lakh
Financeable debtors
₹135 lakh × 60% = ₹81 lakh
Drawing Power
₹142.5 lakh + ₹81 lakh = ₹223.5 lakh
Therefore, the drawing power is ₹2.235 crore, compared with the sanctioned limit of ₹3 crore.
If the borrower's outstanding balance is ₹2.6 crore:
₹260 lakh − ₹223.5 lakh = ₹36.5 lakh
The borrower is therefore ₹36.5 lakh above the calculated DP, despite remaining within the sanctioned ₹3 crore limit.
This is why monitoring only the sanctioned limit can miss an important working-capital warning signal.
Why Stock Statements Matter
Drawing power is only as reliable as the stock statement used to calculate it.
Borrowers generally submit periodic statements showing:
- Raw materials
- Work in progress
- Finished goods
- Trade receivables
- Receivable ageing
- Trade creditors
The lender uses this information to calculate eligible security.
The challenge is that much of this information is borrower-reported. Several weaknesses can therefore distort DP.
Stock Valued Above an Appropriate Basis
Inventory valuation needs to follow the applicable accounting and lending requirements.
If finished goods are reported at selling price rather than an appropriate valuation basis, the value of eligible security can be overstated.
Obsolete or Slow-Moving Inventory
Inventory that has not moved for an extended period may continue to appear in the reported stock figure.
Without appropriate ageing or inspection, obsolete inventory can continue contributing to the apparent security value.
Debtor Ageing Problems
Receivable ageing can also be misleading.
Part payments, credit notes, adjustments, or changes in invoice references can make older receivables appear newer unless the underlying transactions are examined.
Double Financing
The same inventory may potentially be:
- Pledged to another lender
- Covered by supplier credit
- Included in another financing arrangement
This can create a risk that the security available to a lender is overstated.
Month-End Timing
The reporting date itself can affect the stock position.
Inventory may temporarily increase around month-end because of delayed dispatches, goods received close to the reporting date, or other timing effects.
For this reason, lenders may use periodic stock audits, inspections, and other verification mechanisms according to their internal policies and exposure levels.
Drawing Power and RBI Asset Classification
Drawing power is not only a credit-control calculation. It can also have implications for asset classification and account monitoring under RBI's income recognition and asset classification framework.
For cash credit and overdraft accounts, an account can be considered "out of order" when the applicable conditions under RBI's IRAC framework are met. These conditions include situations where the outstanding balance remains continuously above the sanctioned limit or drawing power for the prescribed period.
RBI's framework also addresses drawings permitted against stock statements that are more than three months old. Such drawings are treated as irregular under the applicable prudential framework.
This creates three important monitoring questions:
- Is the borrower operating within the current drawing power?
- Is the DP based on a sufficiently current stock statement?
- Does the account meet any applicable "out of order" conditions?
For lenders, DP monitoring is therefore a portfolio-quality issue, not just a documentation exercise.
Stale DP data can create classification risk and may prevent the lender from identifying deterioration in working-capital security in time.
How Lenders Can Validate Drawing Power
A stock statement should not be treated as the only source of truth.
Credit and monitoring teams can compare reported security with independent transaction and tax data.
Three checks are particularly useful.
1. Compare Purchases With GST Inward Supplies
Suppose a borrower reports that inventory increased by ₹60 lakh during a quarter.
The lender can compare the reported movement with GST purchase and inward-supply information for the same period.
A rising stock figure combined with relatively flat purchases does not automatically prove manipulation. Inventory can change because of opening stock, production, valuation, or timing differences.
However, the discrepancy creates an important question:
What explains the increase in reported inventory?
The analyst can then examine purchases, opening stock, production, sales, and valuation changes.
2. Compare Sales With Debtor Build-Up
Trade receivables generally increase when a business makes credit sales that have not yet been collected.
A lender can therefore compare:
- GSTR-1 outward supplies
- Bank collections
- Reported debtor balances
If sales remain broadly flat and collections remain stable while declared debtors suddenly increase, the change deserves investigation.
Possible explanations include:
- Longer customer credit periods
- Delayed collections
- Large invoices near period-end
- Customer concentration
- Credit notes or adjustments
- Timing differences
The objective is to determine whether the reported debtor balance is supported by the underlying business activity.
3. Compare Supplier Payments With Creditors
Trade creditors reported in the stock statement can also be tested against bank transactions.
Bank statements can reveal:
- Supplier payments
- Payment frequency
- Delayed settlements
- Large supplier transactions
- Changes in supplier concentration
If the borrower reports a particular creditor position but actual supplier-payment behaviour suggests a materially different working-capital cycle, the discrepancy should be investigated.
This helps test whether the creditor deduction used in the DP calculation is reasonable.
A Practical Drawing Power Validation Workflow
A lender can turn DP monitoring into a repeatable process:
Stock Statement
↓
Extract inventory and debtor data
↓
Apply ageing and eligibility rules
↓
Deduct applicable creditors
↓
Apply sanction-specific margins
↓
Calculate drawing power
↓
Compare DP with sanctioned limit
↓
Compare DP with actual outstanding
↓
Compare purchases with GST inward supplies
↓
Compare sales and collections with GST and bank data
↓
Validate creditor payments
↓
Flag exceptions for credit review
This approach shifts DP monitoring from a periodic spreadsheet exercise to a continuous credit-control process.
Using Bank and GST Data for DP Monitoring
Independent data becomes especially valuable when lenders manage multiple accounts, large transaction volumes, or frequent stock statements.
A structured financial-analysis system can help surface information such as:
- Month-wise GST inward supplies
- Month-wise GST outward supplies
- GST filing patterns
- Business collections
- Supplier payments
- Cash-credit utilisation
- Loan obligations
- Unusual transaction patterns
FinEye's GST Analyser can structure month-wise inward and outward supply information, while its Bank Statement Analyser can help classify collections, supplier payments, and credit utilisation.
Together, these data points can provide a second layer of evidence against which reported stock and receivables can be tested.
The goal is not to replace the borrower's stock statement.
It is to validate the assumptions behind the drawing power calculation using independent data.
Why Monthly DP Monitoring Matters
A sanctioned working-capital limit can remain unchanged while the underlying security changes significantly.
Consider this example:
| Period | Sanctioned Limit | Drawing Power | Outstanding |
|---|---|---|---|
| Month 1 | ₹3 crore | ₹2.70 crore | ₹2.40 crore |
| Month 2 | ₹3 crore | ₹2.35 crore | ₹2.45 crore |
| Month 3 | ₹3 crore | ₹2.10 crore | ₹2.50 crore |
The sanctioned limit remains ₹3 crore throughout.
But the relationship between outstanding borrowing and eligible security deteriorates each month.
That is the signal a monitoring team needs to identify.
Monitoring DP only at renewal or enhancement can miss deterioration that develops between review dates.
Key Takeaways
- Drawing power is different from the sanctioned credit limit. It reflects the amount that can be drawn against eligible security under the facility's terms.
- Unpaid stock is generally deducted, while receivables outside the permitted eligibility criteria are excluded.
- Margins vary by asset and sanction. Stock and debtors can have different margins.
- A borrower can be within the sanctioned limit but above its drawing power, creating an important irregularity.
- Stock statements can be affected by valuation, ageing, double financing, and reporting-date issues.
- GST inward supplies can help validate reported purchases and inventory movement.
- GST outward supplies and bank collections can help test debtor build-up.
- Bank supplier payments can help validate reported creditor balances.
- DP should be monitored continuously, not only during renewal or enhancement.
- Stale stock statements and persistent excesses against DP can have implications under RBI's applicable asset-classification framework.
The central principle is simple:
A sanctioned limit tells you how much the bank has agreed to provide. Drawing power tells you how much the borrower can draw against the eligible security available now.
For working-capital lenders, keeping these two numbers separate is the foundation of effective drawing-power monitoring.
