Drawing Power Calculator: Formula, Margin Rates and a Worked Cash Credit Example

Drawing power is the amount a cash credit borrower may actually draw this month. Take eligible stock, deduct creditors for goods, apply the stock margin; take eligible book debts inside the ageing cut-off, apply the book-debt margin; add the two. The borrower draws the lower of DP or the sanctioned limit.

Key facts

• Drawing power moves monthly; the sanctioned limit does not. The limit is what the credit committee approved once. DP is recomputed from every stock and book-debt statement, and it can fall 20-30% in a single month without the borrower's gross stock figure falling at all.
• YuSight spreads the stock statement with 100% of figures cited, each stock, creditor and debtor-ageing number linked back to the page of the statement it came from with one-click verification — so a DP dispute is settled by opening the source, not by re-keying the schedule.
• A stale statement makes the whole outstanding irregular. RBI's IRACP Master Circular states at paragraph 4.2.4 that "the outstanding in the account based on drawing power calculated from stock statements older than three months, would be deemed as irregular," and that a working capital account "will become NPA if such irregular drawings are permitted in the account for a continuous period of 90 days even though the unit may be working or the borrower's financial position is satisfactory" (RBI, Master Circular RBI/2023-24/06, 1 April 2023).
• Non-renewal is a separate trap. The same circular: "an account where the regular/ ad hoc credit limits have not been reviewed/ renewed within 180 days from the due date/ date of ad hoc sanction will be treated as NPA."
• For small units the limit itself may be turnover-driven, not DP-driven. RBI's MSME FAQs record that "as per Nayak Committee Report, working capital limits to SSI units is computed on the basis of minimum 20% of their estimated turnover up to credit limit of Rs.5 crore" (RBI, MSME FAQs, updated 29 July 2025). DP still governs the monthly draw.

What is drawing power and how is it different from the sanctioned limit?

The sanctioned limit is a ceiling set at appraisal, on projected turnover and a working capital gap assessment. Drawing power is a security-cover test run every month against the assets actually on the borrower's floor and ledger.

The borrower gets the lower of the two. A ₹5 crore limit with a ₹3.08 crore DP is a ₹3.08 crore facility this month. This is one of the first things a reviewer checks in a credit appraisal memorandum — an appraisal note that quotes the limit and never quotes the DP trend has skipped the part where the account actually behaves.

What is the drawing power formula?

Written out in full, with the sequence that matters:

Eligible stock = Total stock − ineligible stock (stores/spares if excluded, obsolete and slow-moving beyond the sanction's cut-off, goods not owned, goods in transit if excluded) Paid stock = Eligible stock − creditors for goods DP from stock = Paid stock × (1 − stock margin %) Eligible book debts = Total sundry debtors − debts older than the ageing cut-off − group/associate and related-party debtors − debtors financed under a separate limit (bill discounting, post-shipment) − disputed and retention-money balances DP from book debts = Eligible book debts × (1 − book-debt margin %) Total drawing power = DP from stock + DP from book debts Permitted drawing = lower of (Total DP, sanctioned limit)

Two sequencing errors show up constantly in branch-computed DP. First, applying margin before deducting creditors — that overstates DP, because margin should sit on the borrower's own money in the stock, not on the supplier's. Second, deducting creditors from total stock rather than eligible stock, which quietly gives credit for obsolete inventory.

What margin rates do banks apply to stock and book debts?

Margins are a matter of the lender's board-approved loan policy and the individual sanction, not of regulation. The ranges below are what an analyst will see across Indian banks and NBFCs; treat them as orientation, and always read the actual sanction letter.

The ageing cut-off for book debts is usually 90 days from invoice date, occasionally 120 days for segments with long institutional payment cycles — government supply, pharma distribution, EPC. The cut-off is a hard edge, not a slope: a ₹40 lakh receivable that is 89 days old carries a 40% margin, and the same receivable at 91 days carries no drawing power at all.

How do you read the stock and book-debt statement?

The statement is a monthly certificate from the borrower, usually one page of stock and one of debtors, signed by a director or partner. What to check before you compute anything:

1. The as-on date. Statement for August must be as at 31 August, not "August" undated. This is the date the three-month rule runs from.
2. Valuation basis. Stock at cost or market, whichever is lower. A statement that silently switches from cost to selling price inflates DP with no change in physical stock.
3. Creditors for goods, not total creditors. Only trade creditors for the inventory being charged. Statutory dues and expense creditors do not belong here.
4. Debtor ageing buckets that reconcile to the total. If the buckets sum to a different number from the debtors total, the statement has been assembled, not extracted.
5. Insurance. Stock hypothecated should be insured with the bank's clause. An expired policy is an eligibility issue, not just a documentation gap.
6. Consistency with GST filings. Sales in the GSTR-1 for the same month should be directionally consistent with the debtor movement. Divergence between the two is where the useful questions start — see our framework for GST return analysis for lending.

Worked example: monthly DP on a ₹5 crore cash credit account

Sriram Polymers Pvt Ltd, an injection-moulding unit near Coimbatore. Sanctioned cash credit limit ₹5,00,00,000. Sanction terms: margin 25% on paid stock, 40% on book debts up to 90 days; stores and spares excluded; slow-moving stock beyond 90 days ineligible; group debtors ineligible.

Statement as at 31 August

Deduct ineligible items:

• Eligible stock = 4,08,00,000 − 49,00,000 = ₹3,59,00,000
• Less creditors for goods = 1,04,00,000
• Paid stock = 3,59,00,000 − 1,04,00,000 = ₹2,55,00,000
• DP from stock = 2,55,00,000 × (1 − 0.25) = ₹1,91,25,000

Book debts as at 31 August

• Start from the 0-90 bucket only = 2,26,00,000
• Less group/associate debtors inside that bucket = 19,00,000
• Less export debtors financed under the separate post-shipment limit = 12,00,000
• Eligible book debts = 2,26,00,000 − 19,00,000 − 12,00,000 = ₹1,95,00,000
• DP from book debts = 1,95,00,000 × (1 − 0.40) = ₹1,17,00,000

Drawing power

• Total DP = 1,91,25,000 + 1,17,00,000 = ₹3,08,25,000
• Sanctioned limit = ₹5,00,00,000
• Permitted drawing = lower of the two = ₹3,08,25,000
• Outstanding at 31 August = ₹3,42,00,000
• DP shortfall = ₹33,75,000 — the account is irregular by that amount

Note what the limit did not tell you. On the sanctioned limit the account looks 68% utilised and comfortable. On drawing power it is already over-drawn.

What happens when the stock ages past 90 days?

The September statement, on the same account. Gross stock has gone up. A cancelled export order pushed ₹67,00,000 of finished goods past the 90-day holding cut-off, and ₹41,00,000 of receivables slipped out of the 0-90 bucket.

Statement as at 30 September

• Ineligible = stores 18,00,000 + slow-moving beyond 90 days 89,00,000 (22,00,000 carried forward + 67,00,000 newly aged) + consignment 9,00,000 = ₹1,16,00,000
• Eligible stock = 4,15,00,000 − 1,16,00,000 = ₹2,99,00,000
• Less creditors for goods 1,11,00,000 → paid stock = ₹1,88,00,000
• DP from stock = 1,88,00,000 × 0.75 = ₹1,41,00,000

• Eligible book debts = 1,88,00,000 − 19,00,000 group − 12,00,000 export = ₹1,57,00,000
• DP from book debts = 1,57,00,000 × 0.60 = ₹94,20,000
• Total DP = 1,41,00,000 + 94,20,000 = ₹2,35,20,000
• Outstanding at 30 September = ₹3,38,00,000
• DP shortfall = ₹1,02,80,000

Drawing power fell ₹73,05,000 — 23.7% in one month — while the borrower's headline current assets rose by ₹15,00,000. Ageing did all the work. An analyst who tracks only the totals on the statement sees a stable account. An analyst who recomputes DP sees an account whose security cover is collapsing.

What happens when drawing power falls below the outstanding?

A DP shortfall is not a default and not, by itself, an NPA. It is a countdown. In sequence:

1. The account is flagged irregular. Core banking will typically bar fresh drawings once outstanding exceeds DP, and interest debits alone can widen the gap.
2. SMA reporting begins if the irregularity persists past the reporting thresholds, and the exposure surfaces on CRILC for other lenders to see.
3. The 90-day clock runs. Under IRACP paragraph 4.2.4, continuous irregular drawings for 90 days classify the account as NPA regardless of how healthy the unit looks.
4. Provisioning and rating consequences follow at the lender's end, not the borrower's.

The credit action is usually one of four: call for stock at a fresh date if the ageing is genuinely a timing artefact; regularise by remittance; carve out a temporary ad hoc limit — remembering that the ad hoc itself carries the 180-day review clock; or restructure the working capital assessment because the borrower's operating cycle has genuinely lengthened. The last is the honest answer more often than the file admits, and it belongs in the CMA data resubmission, not in a monthly DP note.

Why is a stale stock statement a red flag?

Because of what the delay usually means, and separately because of what the regulation says.

The regulation is unambiguous: DP computed from a statement older than three months makes the outstanding irregular. That is a mechanical consequence and it applies even to a borrower with a spotless account.

The behavioural signal is the more useful one. Borrowers do not stop sending stock statements at random. They stop when the statement would show something — inventory that has stopped moving, receivables that have aged, creditors that have ballooned because payments have slowed. A pattern of statements arriving 40 days late, or arriving on time but with round-number stock figures that repeat month after month, is a stress signal before any of it reaches the bank statement.

Cross-checks worth running on a suspect statement:

• Stock turnover implied by the statement vs. the audited financials. A unit that showed 6.2 inventory turns last year and implies 3.1 turns this year has either lost sales or stopped writing off dead stock.
• Debtor days implied vs. the ageing schedule. They must agree. When the schedule says 62 days and the balance sheet implies 104, one of the two documents is wrong.
• Declared sales vs. GSTR-1 and vs. e-way bill volumes for the same months.
• Receipts in the CC account vs. declared collections. If ₹2.26 crore of 0-90 day debtors are supposedly collecting, the credit turnover in the account should show it.
• Declared receipts vs. TDS credits. Corporate and institutional customers deduct tax at source, so the borrower's Form 26AS carries an independent trace of who actually paid them and when.

Does the loan system for delivery of bank credit change the DP calculation?

For large borrowers, it changes what DP governs. RBI's Guidelines on Loan System for Delivery of Bank Credit require that for borrowers with "aggregate fund based working capital limit of ₹1500 million and above," a minimum share of the sanctioned limit be carved out as a working capital demand loan — set at 40% initially and, per the circular, "the 40 percent loan component will be revised to 60 percent, with effect from July 1, 2019" (RBI, RBI/2018-19/87, 5 December 2018).

The DP arithmetic is unchanged. What changes is that only the cash credit residue fluctuates with it, while the WCDL portion sits as a fixed-tenor drawdown. Analysts running DP on such accounts should confirm whether their lender computes DP against the aggregate limit or against the CC component alone — practice varies.

How YuSight handles the stock statement

Stock and book-debt statements arrive as scanned PDFs, phone photographs of a signed sheet, and Excel files with the ageing schedule on a hidden tab. YuSight's Document Intelligence classifies them, maps each to the right borrower entity in a group structure, and Financial Spreading extracts the stock heads, the creditors line and the ageing buckets into a standard format. Every extracted figure carries a citation to the source page, so the DP a reviewer sees can be verified against the borrower's own document in one click — and the month-on-month DP series is built automatically rather than re-keyed each cycle.

FAQ

How do you calculate drawing power in a cash credit facility?

Take eligible stock, subtract creditors for goods to get paid stock, and apply the stock margin. Separately take book debts inside the ageing cut-off, strip out group and separately-financed debtors, and apply the book-debt margin. Add the two — that is your drawing power.

What margin is applied to stock and book debts?

Most Indian lenders sit around 25% on stock and 40% on book debts within 90 days, but it is entirely a matter of the sanction. Stores and spares are commonly excluded altogether, and work in progress often carries a stiffer margin than finished goods.

What happens when drawing power falls below the outstanding?

The account becomes irregular to the extent of the shortfall and fresh drawings are usually blocked. If the irregularity runs for a continuous 90 days, RBI's IRACP norms classify the account as an NPA even if the unit is trading normally.

Is drawing power the same as the sanctioned limit?

No. The sanctioned limit is the ceiling approved at appraisal; drawing power is what the security actually supports this month. The borrower can draw only the lower of the two, which is why a healthy-looking limit tells you nothing on its own.

How often does a borrower have to submit a stock statement?

Monthly is the norm for cash credit accounts. The hard outer edge is three months — beyond that, RBI treats drawing power computed from the statement as stale and the whole outstanding as irregular.

Are creditors for goods always deducted before margin?

Yes, and the order matters. Deduct creditors first to get paid stock, then apply margin. Applying margin first and deducting creditors afterwards overstates drawing power, because it gives the borrower margin credit on stock the supplier has not been paid for.

Why do book debts carry a higher margin than stock?

Because you cannot repossess a receivable. Stock is a physical asset the bank has a charge over and can realise; a book debt depends on a third party paying, and the bank has no relationship with that third party.

Does a DP shortfall automatically make the account an NPA?

Not immediately. It starts a 90-day clock. If the borrower regularises within that window — by remittance, by fresh stock, or through a properly sanctioned ad hoc limit — the account does not slip. Ignore it for a quarter and it does.

What is a drawing power certificate?

It is the branch's internal record of the DP computed for a given month, showing the stock and debtor figures used, the deductions, the margins applied and the resulting DP. Auditors and RBI inspectors read it alongside the borrower's statement to check the bank did the arithmetic correctly.

Key takeaways

• Drawing power is a monthly security-cover test, not an annual credit decision. Recompute it every cycle.
• Deduct creditors from eligible stock before applying margin. Sequence errors flatter DP by lakhs.
• The book-debt ageing cut-off is a cliff, not a slope. A receivable at 91 days contributes nothing.
• Gross current assets can rise while DP falls hard. Track DP, not the statement totals.
• A stock statement older than three months makes the outstanding irregular under RBI's IRACP norms, and 90 continuous days of irregular drawings makes it an NPA.
• Late or repetitive stock statements are a behavioural signal that usually arrives before the bank statement deteriorates.
