V-IDR: Viswanathan Indian Discount Rate for Startup DCF Valuation
The Viswanathan Indian Discount Rate (V-IDR) is a proprietary discount rate framework developed by CA V. Viswanathan specifically for DCF valuation of Indian startups and unlisted companies. Traditional WACC fails for pre-revenue startups that have no debt, no listed beta, and no stable cash flows. The V-IDR solves this by building a discount rate from first principles using India-specific risk factors, sector betas, illiquidity premiums, and — uniquely — a regulatory compliance risk factor that quantifies the cost of non-compliance in the Indian startup ecosystem.

Why Traditional WACC Fails for Indian Startups
The Weighted Average Cost of Capital (WACC) is the gold standard for discounting cash flows in corporate finance. But it was designed for mature, listed companies with observable market data. When applied to Indian startups, WACC breaks down at every step:
- No debt component: Most pre-revenue startups have zero debt, making the debt side of WACC irrelevant. WACC degenerates into just the cost of equity — but without the framework to handle startup-specific risks.
- No listed beta: Beta requires regression of stock returns against a market index. Unlisted startups have no stock price, forcing valuers to use crude sector proxies without systematic adjustment.
- Illiquidity is ignored: WACC assumes liquid, tradeable securities. Startup equity is deeply illiquid — there is no secondary market, and lock-in periods of 3-7 years are common. This illiquidity risk is often ignored or handled as an ad-hoc add-on.
- Indian regulatory complexity: WACC captures none of the compliance risk that directly impacts Indian startup valuations — FEMA filings, angel tax exposure under Section 56(2)(viib), ESOP compliance, GST status, and IBBI regulatory requirements.
The V-IDR framework addresses each of these failures by building a discount rate from components that are observable, justifiable, and specific to the Indian startup context.
The V-IDR Formula
Where:
- Rf = Risk-Free Rate (10-year Indian Government Bond yield)
- ERP = Equity Risk Premium for India (per Damodaran or equivalent)
- βunlisted = Unlisted company beta (sector proxy adjusted for stage and size)
- Ω = Compliance Risk Premium (regulatory and filing risk)
- Λ = Illiquidity Premium (discount for lack of marketability)
Component Breakdown
Rf — Risk-Free Rate
The 10-year Indian Government Bond (G-Sec) yield serves as the risk-free rate. As of early 2026, this stands at approximately 7.2%. This is the baseline return an investor can earn with zero credit risk in India. For startups seeking foreign investment, some valuers use a blended rate incorporating the US 10-year Treasury plus a country risk premium — but for domestic valuations (IBBI, Section 56, Companies Act), the G-Sec yield is the appropriate benchmark.
ERP × βunlisted — Risk-Adjusted Market Premium
The Equity Risk Premium (ERP) represents the additional return investors demand for holding equities over risk-free bonds. India's ERP, per Aswath Damodaran's annual estimates, is approximately 7.5% (mature market premium + country risk premium). This is multiplied by the unlisted beta — a sector-specific risk coefficient adjusted for the startup's stage. Since unlisted companies have no traded shares, we derive beta from listed sector proxies (e.g., Nifty IT index constituents for SaaS startups) and apply an unlisted premium multiplier of 1.2-2.0x based on stage.
| Sector | Listed Beta Proxy | βunlisted Range |
|---|---|---|
| SaaS / IT Services | 1.1 – 1.3 | 1.5 – 2.2 |
| Fintech | 1.2 – 1.5 | 1.8 – 2.5 |
| D2C / E-commerce | 1.0 – 1.4 | 1.5 – 2.3 |
| Healthtech / Biotech | 0.9 – 1.3 | 1.4 – 2.2 |
| Deeptech / Hardware | 1.3 – 1.6 | 2.0 – 2.8 |
| Edtech | 1.0 – 1.2 | 1.4 – 2.0 |
| Manufacturing / Industrial | 0.8 – 1.1 | 1.2 – 1.8 |
Ω — Compliance Risk Premium
This is the unique contribution of the V-IDR framework. Indian startups operate under a complex regulatory web — Companies Act 2013, FEMA, GST, Income Tax, SEBI (for fundraising), and IBBI (for insolvency). Non-compliance in any of these creates tangible risk that directly impacts valuation. The V-IDR explicitly quantifies this as a discount rate add-on.
| Compliance Rating | Ω Value | Criteria |
|---|---|---|
| Excellent | 0% | DPIIT recognized, all filings current, no pending notices, clean audit reports |
| Good | 1.5% | Minor filing delays (< 30 days), all returns current, no material issues |
| Fair | 3% | Pending FEMA filings, delayed GST returns, minor compliance gaps |
| Poor | 5% | Material non-compliance, show-cause notices received, unresolved tax demands |
| Critical | 8% | Active regulatory litigation, NCLT proceedings, FEMA compounding, prosecution |
Λ — Illiquidity Premium
Startup equity is fundamentally illiquid. Unlike listed shares that can be sold on an exchange within seconds, startup equity has no secondary market, is subject to lock-in periods (typically 1-3 years for founders, longer for ESOP holders), and requires buyer identification for any transfer. Empirical studies suggest illiquidity discounts of 20-35% on value — which translates to a discount rate premium of 10-25% in a DCF model. The V-IDR uses a default of 15% for standard seed/Series A startups, adjustable based on specific liquidity factors.
Interpreting the V-IDR
| V-IDR Range | Interpretation | Implication for DCF |
|---|---|---|
| < 25% | Conservative — typical for later-stage or compliant startups | Higher present values; favorable for founders in valuation negotiations |
| 25% – 35% | Moderate — standard range for seed/Series A Indian startups | Balanced risk-return; defensible in most regulatory submissions |
| 35% – 45% | Aggressive — reflects high sector risk or compliance issues | Lower present values; investors may demand larger equity stakes |
| > 45% | Extreme — signals fundamental risk concerns | DCF may not be the appropriate valuation method; consider asset-based or market approaches |
Worked Example
Consider a SaaS startup based in Chennai seeking Series A funding. The startup is DPIIT-recognized with clean compliance history.
Parameters: Rf = 7.2%, ERP = 7.5%, βunlisted = 1.8 (SaaS/IT sector proxy), Λ = 15%, Ω = 0% (Excellent compliance)
Interpretation: A V-IDR of 35.7% is in the moderate-to-aggressive range, typical for early-stage SaaS startups. This provides a mathematically justified basis for the discount rate in a DCF model, far more defensible than an arbitrary 35% assumption.
Now consider the same startup but with pending FEMA filings (Fair compliance):
The 3% compliance penalty increases the discount rate, directly reducing the DCF valuation — quantifying the real cost of regulatory non-compliance.
When to Use V-IDR vs. WACC
| Aspect | Traditional WACC | V-IDR |
|---|---|---|
| Best suited for | Listed companies, mature businesses | Pre-revenue startups, early-stage companies |
| Debt component | Required (Kd) | Not required (no debt assumption) |
| Beta source | Listed company regression | Sector proxy + stage adjustment |
| Compliance risk | Not captured | Explicitly modeled (Ω factor) |
| Illiquidity | Sometimes added as a separate adjustment | Integrated into the formula |
| Indian regulatory context | Generic | Built for IBBI, Rule 11UA, Companies Act |
| Defensibility | Strong for listed companies | Strong for startup valuations |
Regulatory Applications
The V-IDR framework is designed to produce discount rates that are defensible in regulatory contexts including IBBI valuations under IBC, Section 56(2)(viib) (Angel Tax) valuations under Rule 11UA, ESOP valuations under Companies Act 2013, and FEMA pricing guidelines for FDI transactions. The framework's explicit modeling of compliance risk is particularly relevant for IBBI registered valuers who must justify their discount rate assumptions in formal valuation reports.
