Bankable DPR Preparation: DSCR, IRR & Plastics Manufacturing Project Appraisal
Detailed Project Report (DPR) preparation for plastics plants, Debt Service Coverage Ratio (DSCR), Internal Rate of Return (IRR), payback period, and bank appraisal.
Bankable DPR Preparation: DSCR, IRR & Plastics Manufacturing Project Appraisal
1. Why This Topic Matters
A bankable Detailed Project Report (DPR) is the gateway to institutional financing for any plastics manufacturing venture — whether setting up a blown film line, an injection moulding unit, or a masterbatch compounding plant. Banks (SBI, SIDBI, HDFC Bank), NBFCs, and state industrial finance corporations (TIIC, KSFC, NSIC) evaluate DPRs using standard financial ratios: DSCR, IRR, NPV, and payback period. An engineer who can prepare a credible DPR with accurate capital cost estimates, working capital projections, and sensitivity analysis can access bank loans, MSME subsidies, and PLI scheme benefits.
2. Learning Objectives
- Define and calculate DSCR, IRR, NPV, and payback period for a plastics project.
- Prepare a capital cost estimate (civil + machinery + working capital) for an injection moulding unit.
- Construct a 5-year projected P&L and cash flow statement.
- Calculate break-even capacity utilisation and margin of safety.
- Identify SIDBI loan products, PLI scheme eligibility, and MSME registration requirements.

3.1 Key Financial Ratios for Bank Appraisal
Debt Service Coverage Ratio (DSCR):
Bank acceptance criterion: DSCR ≥ 1.5 (minimum 1.25 for MSME/SIDBI)
Internal Rate of Return (IRR): IRR is the discount rate r at which NPV = 0:
Bank acceptance criterion: IRR > Cost of capital + 5% risk premium (typically IRR > 18–22% for manufacturing in India)
Break-even Utilisation:
3.2 Capital Cost Structure for an Injection Moulding Unit (Example: 5-machine, 500 MT/year)
| Capital Item | Estimated Cost (₹ Lakh) |
|---|---|
| Land & site development | 25–40 |
| Civil construction (1,200 m² factory) | 60–90 |
| Injection moulding machines (5 × 250T) | 150–200 |
| Moulds (customer-supplied or company) | 50–100 |
| Utilities (compressor, chiller, DG set) | 20–30 |
| Pre-operative expenses (DPR, insurance) | 8–12 |
| Working capital margin (bank norms: 25% of WC) | 20–35 |
| Total Project Cost | 333–507 lakh |
Typical Debt:Equity ratio for MSME plastics unit: 70:30 (bank loan:promoter contribution)
3.3 P&L Projections — 5-Year Model
Standard assumptions for injection moulding unit (Year 1 = 60% utilisation, Year 3+ = 85%):
| Line Item | Basis |
|---|---|
| Revenue | Capacity × capacity utilisation × selling price (₹/kg) |
| Raw material cost | 60–70% of revenue (PP/PE at ₹90–120/kg) |
| Power cost | 0.8–1.2 kWh/kg × ₹8/unit |
| Labour | 8–12 operators × ₹20,000/month |
| Depreciation | SLM — machinery 10 years, civil 30 years |
| Interest | On term loan at 10.5–12% p.a. |
| EBITDA margin | Target: 15–20% for healthy project |
3.4 PLI Scheme and MSME Subsidies
PLI (Production Linked Incentive) for Advanced Chemistry Cell / Specialty Chemicals (2021): 5–10% of incremental sales over base year for eligible polymer compounders and specialty chemical manufacturers.
MSME Capital Subsidy (CLCSS): 15% capital subsidy up to ₹15 lakh on eligible plant & machinery for Micro and Small enterprises — applicable to injection moulding machines, extruders, and compounding lines registered under MSME Act.
4. Worked Example
<div className="problem-statement">{ "title": "Bankable DPR Preparation: DSCR, IRR & Plastics Manufacturing Project Appraisal — Industrial Process Flow Diagram (PFD)", "subtitle": "ISO 10628 Unit Operations & Thermodynamic Control Sequence", "steps": [ { "step": 1, "title": "Raw Material Feed & Metering", "description": "Drying to < 0.02% moisture and gravimetric dosing", "parameters": "80°C - 100°C", "output": "Conditioned Feed" }, { "step": 2, "title": "Reaction & Polymer Melt Processing", "description": "Controlled thermal shear dissipation and phase transition", "parameters": "220°C - 260°C", "output": "Homogenous Melt" }, { "step": 3, "title": "Shaping & Solidification", "description": "Die extrusion or mold cavity pressure packing", "parameters": "60 - 120 bar", "output": "Formed Component" }, { "step": 4, "title": "Quality Inspection & Testing", "description": "ASTM D638 / ISO 527 tensile & MFI compliance check", "parameters": "QA Passed", "output": "Finished Grade" } ], "recycleLoop": "Closed-loop sprues and edge-trim regrind re-fed into main hopper at maximum 15% blend ratio.", "notes": "Standard Indian Industrial Practice (CIPET / Reliance / Supreme Petrochem Protocol)" }
Problem: A plastics compounding plant has annual EBDT (Earnings Before Depreciation & Tax) after tax = ₹42 lakh. Annual loan repayment (principal) = ₹20 lakh. Annual interest = ₹14 lakh. Calculate DSCR.
Net Cash Accrual = EBDT after tax (add back depreciation if DPR convention) = ₹42 lakh
Assessment: DSCR = 1.24 — just below SIDBI's minimum of 1.25. The banker will flag this as marginal. Recommendations: (a) reduce term loan by increasing promoter equity, (b) renegotiate loan tenure from 5 to 7 years to reduce annual principal repayment, or (c) improve revenue projection by adding a higher-margin product line.

SIDBI (Small Industries Development Bank of India) runs dedicated plastics sector loan schemes under their MSME lending platform — offering term loans up to ₹2 crore at 9.5–11% p.a. for plastics processing units with collateral under Udyam registration.
PLEXCONCIL (Plastics Export Promotion Council) provides DPR templates and market feasibility reports for export-oriented plastics processing units — particularly useful for injection moulding, packaging, and engineering compounds targeting EU, USA, and Middle East export markets.
6. Key Takeaways & Glossary
- DSCR (Debt Service Coverage Ratio): NCA / (Principal + Interest); ≥ 1.5 preferred, 1.25 minimum for MSME.
- IRR (Internal Rate of Return): Discount rate making NPV = 0; target > 18–22% for Indian plastics manufacturing.
- BEP (Break-Even Point): Capacity utilisation at which revenue = total costs.
- PLI Scheme: Production Linked Incentive — government subsidy on incremental production for eligible industries.
- CLCSS: Credit Linked Capital Subsidy Scheme — 15% capital subsidy up to ₹15 lakh for Micro/Small enterprises.
- Debt:Equity ratio: 70:30 typical for MSME manufacturing — higher equity improves DSCR.
