Quick Summary — What You Need to Know
- The turnover method is mandatory, not optional, for smaller borrowers: RBI requires banks to use it for aggregate fund-based working capital limits up to ₹5 crore, computing a minimum bank finance of 20% of projected annual turnover.
- MPBF is the older, more complex method: from the 1974 Tandon Committee, it calculates finance based on actual current assets and liabilities rather than a flat percentage of turnover, and is generally applied above the ₹5 crore threshold.
- The turnover method formula is simple: total working capital need is set at 25% of projected annual turnover, split as 5% borrower margin and a minimum 20% bank finance — a business projecting ₹2 crore turnover should be looking at a minimum ₹40 lakh limit.
- CC, OD, and WCDL are different instruments answering different needs: cash credit is a revolving facility against stock and book debts requiring regular stock statements; overdraft is typically simpler, often against property or fixed deposits; WCDL is a fixed-drawdown loan component, mandatory for large borrowers above ₹150 crore in working capital under a specific RBI rule.
- Banks can sanction above the minimum, since the 20% turnover-method figure is a floor, not a ceiling — a business with a genuinely faster cash conversion cycle can often justify more.
- Important takeaway: knowing which method legally applies to your limit size is the starting point for knowing whether you're actually under-financed relative to what RBI's own rules entitle you to ask for.

The Two Methods, Plainly
The Turnover Method Formula
This method, recommended by the P.R. Nayak Committee in 1992, was designed specifically because the traditional MPBF approach was impractical and burdensome for smaller borrowers with limited financial literacy and record-keeping capacity. RBI made it mandatory for eligible small borrowers, and it remains the governing method for the overwhelming majority of MSME cash credit and overdraft accounts in India today.
The MPBF Formula
MPBF has two commonly used variants. Method 1 finances 75% of the working capital gap (current assets minus current liabilities excluding bank borrowing), leaving the borrower to fund the remaining 25% from long-term sources, producing a minimum current ratio of 1:1. Method 2 is stricter: the borrower must fund 25% of total current assets rather than just the gap, producing a minimum current ratio of 1.33:1. The 1979 Chore Committee pushed larger borrowers toward Method 2 specifically to improve that ratio and reduce bank exposure over time.
Comparison: MPBF vs. Turnover Method
| Aspect | Turnover Method (Nayak) | MPBF (Tandon) |
|---|---|---|
| Applicability | Mandatory up to ₹5 Cr aggregate WC limit | Typically above ₹5 Cr |
| Complexity | Simple — one formula, one input | Complex — full current asset/liability analysis |
| Documentation | Projected turnover figure | Detailed financial statements, ratios |
| Origin | 1992 Nayak Committee | 1974 Tandon Committee |
CC vs. OD vs. WCDL: The Instruments That Deliver the Limit
Whichever method sizes your limit, the facility itself takes one of a few forms. Cash credit is the classic revolving facility, secured against stock and book debts, requiring regular stock statements and drawing power recalculation. Overdraft is typically simpler to operate — often secured against property, fixed deposits, or offered against a clean profile for salaried or professional borrowers — without the stock statement mechanics that govern cash credit. Working Capital Demand Loan (WCDL) is a fixed-drawdown component carved out of the total sanctioned limit, drawn once rather than fluctuating daily, and RBI mandated that large borrowers with aggregate working capital limits of ₹150 crore and above take a meaningful portion of that limit as WCDL specifically to encourage better cash management — a rule that affects large corporates far more than typical MSME borrowers.
Worked Example: Sizing a Turnover-Method Limit
The Business
A trading firm projected ₹2 crore in annual turnover for the coming year, well within the ₹5 crore turnover-method threshold.
The Calculation
Total working capital need was set at 25% of that turnover, split as a 5% borrower margin and a minimum 20% bank finance.
The Minimum Limit
That 20% minimum translated into a specific floor for the bank-financed cash credit or overdraft limit — the number the business was entitled to ask for as a starting point, not a ceiling.
The Opportunity
Because 20% is a floor, a business with a genuinely faster cash conversion cycle or documented higher working capital need could reasonably request more, supported by the right file.
Insider Insight: The 20% Is a Floor, Not a Ceiling
Decision Matrix: Which Applies to You
| If your working capital need is... | Expect |
|---|---|
| Under ₹5 crore aggregate limit | Turnover method, minimum 20% of projected turnover |
| Above ₹5 crore | MPBF assessment, typically Tandon Method 2 |
| Above ₹150 crore | Mandatory WCDL component alongside cash credit |
| Genuinely faster/slower cash cycle than typical | Document it — the floor figure can be exceeded with justification |
