Cash Credit Loan Limit: How Banks Actually Calculate What You Get
Most business owners never ask how their cash credit limit was calculated — they just accept the number the relationship manager quotes. There are two RBI-recognised formulas a bank can use, they don't always produce the same answer for the same business, and knowing which one applies to your loan size is the fastest way to check whether you've actually been under-sanctioned.
📍 CreditCares — Godrej Waterside, Sector V, Bidhannagar — helping West Bengal businesses check their CC eligibility against both formulas before accepting a sanction.
Quick Summary
- Two formulas, two different answers. The turnover method and the MPBF method assess eligibility differently, and for the same business, they don't always agree.
- Turnover method is simpler and more common for smaller limits. 20% of projected turnover as the working capital requirement, 5% as your margin, 15% as the bank's finance — commonly applied up to around ₹5 crore.
- MPBF method looks at your actual working capital cycle. A slower receivables cycle or heavier stock holding can mean a bigger eligible limit under this method, even at identical turnover.
- You can ask which method was used. The appraisal note behind your sanction states it, and most banks will share it on request.
- The limit isn't fixed once it's approved. It's revisited every renewal, and your receivables discipline, credit rating, and documentation all move the number over time.
- If eligibility is fine but collateral is the blocker, that's a different problem with a different fix — see the CGTMSE route below.
Most relationship managers default to whichever method their bank's internal system runs first, not necessarily the one that would give you the higher number. For limits roughly between ₹2 crore and ₹5 crore — the zone where a business could plausibly qualify under either method — it's worth directly asking which one was applied and requesting the alternative calculation for comparison before you sign the sanction letter, not after.
01 · Method one
The Turnover Method (Nayak Committee Formula)
This method exists because detailed balance-sheet-based assessment is disproportionate paperwork for a smaller business. Instead of projecting current assets and liabilities in detail, the bank takes your realistic projected turnover, applies the formula, and arrives at a limit quickly — provided the turnover projection itself is credible and backed by GST returns and past performance.
Projected Turnover
₹2.00 Cr
WC Requirement (20%)
₹40 L
Your Margin (5%)
₹10 L
Bank Finance / CC Limit (15%)
₹30 L
Worked example: Ganguly Textiles, a hosiery finishing unit in Serampore, projects ₹2 crore turnover for FY27 backed by the last two years' GST returns. Under the turnover method, that supports a cash credit limit of ₹30 lakh — 15% of the projected figure.
02 · Method two
The MPBF Method (Tandon Committee)
This method looks at the actual shape of your working capital cycle instead of assuming a fixed relationship with turnover. A business that holds stock longer or collects receivables slower shows a larger working capital gap — and can qualify for a bigger limit under MPBF than the turnover method would suggest, even at identical revenue. The reverse is also true: a business with a tight, fast-moving cycle can find MPBF gives less than the flat turnover formula would.
03 · Comparison
Turnover Method vs MPBF Method
| Basis | Turnover Method | MPBF Method |
|---|---|---|
| Formula basis | Flat % of projected turnover | Actual projected current assets & liabilities |
| Typical applicability | Limits up to ~₹5 crore | Larger or more complex limits |
| Data required | Turnover projection, GST returns | Detailed CMA data, projected balance sheet |
| Borrower margin | Fixed at 5% of turnover | Minimum 25% of current assets (Method II) |
| Sensitive to | Turnover growth only | Receivables cycle, stock holding, operating cycle |
| Best for | Smaller, straightforward accounts | Businesses with a genuinely long or short operating cycle |

What Actually Moves Your Number
- Turnover trend, not just the latest figure. A rising trend across GST returns supports a higher projection than a flat or declining one, even at the same current-year number.
- Receivables and stock cycle length. Under MPBF, a longer cycle increases your working capital gap and your potential limit — but also invites closer scrutiny of why the cycle is that long.
- Credit rating and conduct history. A stronger external rating or a clean track record on an existing facility gives the sanctioning authority more room within the bank's own risk policy.
- Margin negotiation. The formula sets a ceiling, not a fixed outcome — some room exists to negotiate the margin percentage itself within a bank's policy band, particularly for well-rated accounts.
- The bank's own sector appetite. Two identical businesses in different industries can get different treatment simply because one sector currently sits inside a bank's preferred exposure and the other doesn't.

How to Legitimately Increase Your Eligible Limit
None of this is about gaming a formula — it's about making sure the formula sees the strongest accurate version of your business.
- Support your turnover projection properly. A number backed by 12–24 months of GST returns and a credible growth story carries more weight than an optimistic estimate with no paper trail.
- Tighten your receivables cycle where you can. Faster collection improves your working capital position generally, and under MPBF assessment it changes the underlying gap calculation directly.
- Strengthen your credit rating before you apply. Clean conduct on existing facilities and timely GST/ITR filings feed directly into the rating the bank uses to size its risk appetite. See CreditCares' CIBIL Score Advisor guidance for the specifics.
- Separate an eligibility problem from a collateral problem. If the bank agrees you qualify for a higher limit but wants more security than you can offer, a CGTMSE-backed structure can close that gap without touching the eligibility calculation itself — see our CGTMSE guide.
- If your current bank consistently under-assesses you, compare a takeover. Identical financials can be read differently by different banks — see our balance transfer comparison and our dedicated guide to cash credit takeover from another bank.
Ask for the credit appraisal note behind your sanction, not just the sanction letter itself. The appraisal note is the internal document that shows exactly which method was applied, the projected figures used, and the margin calculation — and many banks, PSU banks in particular, will share it on request. Reading it is the single fastest way to confirm whether your limit genuinely matches what the formula supports, rather than taking the final number on trust.

CC Limit Estimator
Run both formulas side by side. The turnover-method estimate only needs your projected turnover; the MPBF estimate needs a rough current assets and current liabilities figure.
Both are indicative estimates for orientation only — your bank's actual policy, margin, and risk assessment will determine the real sanctioned figure.
08 · FAQ
Frequently Asked Questions
What is a cash credit loan limit?
It's the maximum amount a bank allows you to draw against a revolving working capital facility, secured against stock and book debts, set using either the turnover method or the MPBF method and refreshed against your actual drawing power as you operate the account.
Which method will my bank use to calculate my limit?
Most banks default to the turnover method for aggregate fund-based requirements up to around ₹5 crore. Above that, or where a bank prefers a more detailed assessment even below the threshold, the MPBF method applies instead.
Can I ask my bank which method they used?
Yes. The appraisal note behind your sanction states the method and the underlying calculation, and most banks will share it on request — it's the fastest way to check your limit against the formula.
Why did two businesses with the same turnover get different limits?
Turnover alone doesn't decide it. Under MPBF, a longer receivables cycle or heavier stock holding shows a bigger working capital gap and can support a larger limit, even at identical revenue.
How can I legitimately increase my eligible limit?
Back your turnover projection with GST history, tighten your receivables cycle, strengthen your credit rating, and if collateral rather than eligibility is the real constraint, look at a CGTMSE-backed structure instead.
09 · Conclusion
Conclusion
The number on your sanction letter isn't handed down — it's the output of a formula, and formulas can be checked. Knowing whether your bank ran the turnover method or the MPBF method, and asking to see the calculation either way, turns "the bank said ₹30 lakh" into a figure you can actually verify.
