DCF Calculator 2026: What is a Business Worth? Free Discounted Cash Flow Valuation Tool ★★★★★

How This DCF Calculator Answers "What is a Business Worth?"

The most fundamental question in investing is "what is a business worth?" Our DCF calculator 2026 provides the answer instantly, using professional discounted cash flow methodology with 2026 market data. With over 50,000 monthly users across Wall Street, private equity, and Main Street, it's the most trusted tool for business valuation. The Discounted Cash Flow (DCF) method values a business based on its future cash flows, discounted back to present value using an appropriate discount rate (typically the Weighted Average Cost of Capital or WACC).

DCF Valuation Formula and Methodology

Enterprise Value Formula: Enterprise Value = Σ(CF₁/(1+r)¹ + CF₂/(1+r)² + ... + CFₙ/(1+r)ⁿ) + TV/(1+r)ⁿ
Where: CF = Cash Flow in each year, r = Discount Rate, n = Projection period (5-15 years), TV = Terminal Value.
Terminal Value (Perpetuity Growth Method): TV = CFₙ × (1+g) ÷ (r - g) where g = long-term growth rate (typically 2-3%, not exceeding GDP growth).
Net Present Value (NPV): NPV = Enterprise Value - Initial Investment. Positive NPV indicates value creation.
Internal Rate of Return (IRR): The discount rate that makes NPV = 0. Higher IRR indicates better returns.

2026 Discount Rate Guide by Investment Type

Large Public Companies (Blue Chip): 8-10% WACC — Stable, predictable cash flows. Risk-free rate (4.2%) + Equity Risk Premium (5.2%) × Beta (0.8-1.0).
Small Public Companies: 10-12% — Includes 2-3% small-cap premium. Higher risk, higher potential returns.
Private Companies (Stable): 12-15% — Illiquidity premium + size premium. Limited public market for shares.
Private Companies (Growth Stage): 15-20% — Higher uncertainty, higher required returns.
Startups (Seed Stage): 30-50% — Very high risk, venture capital target returns. May have no positive cash flows initially.
Real Estate: 6-10% — Based on property cap rates plus risk premium.

Terminal Value Calculation Methods

Perpetuity Growth Method (Gordon Growth Model): TV = Final Year Cash Flow × (1 + Terminal Growth Rate) ÷ (Discount Rate - Terminal Growth Rate). Terminal growth should not exceed long-term GDP growth (2-3% for 2026). This method assumes the business will continue generating cash flows forever at a stable growth rate.
Exit Multiple Method: TV = Final Year EBITDA × Industry Multiple. 2026 industry multiples: Technology 12-18×, Healthcare 10-14×, Consumer Goods 8-12×, Industrial 7-10×, Financial Services 6-9×. This method is based on comparable company transactions in the same industry.

How to Choose the Right Discount Rate

The discount rate (WACC) reflects the riskiness of the investment. Lower risk = lower discount rate = higher valuation. Higher risk = higher discount rate = lower valuation. For public companies, use CAPM: Re = Rf + β × (Rm - Rf) where Rf = 4.2% (10-year Treasury), Rm - Rf = 5.2% (equity risk premium), β = stock's volatility relative to market. For private companies, add illiquidity premium (2-5%) and size premium (2-3%). Our calculator uses these 2026 market inputs automatically when you select the appropriate investment type in your analysis.

Growth Rate Assumptions: Critical Input

Growth rates are often the most sensitive input in DCF valuation. Overly optimistic growth assumptions can significantly overvalue a business. Use stage-appropriate growth rates: Startups (30-50% but only for 2-3 years), Growth companies (15-25% for 3-5 years), Mature companies (5-10% for 5-10 years), Declining companies (<5% or negative). Terminal growth should be conservative — never exceed long-term GDP + inflation (2-3% for 2026). Our calculator uses a declining growth rate model for longer projections.

Interpreting Your DCF Results

Positive NPV (Enterprise Value > Initial Investment) indicates the investment creates value and should be considered. Negative NPV indicates the investment destroys value at your required return. IRR should exceed your hurdle rate (typically 8-12% for most investments). For venture capital, target IRR >25-30%. For private equity, target IRR >15-20%. For public stocks, compare DCF value to current market price — if DCF value is >20% higher than market price, the stock may be undervalued (buy signal). Always use a margin of safety (20-30%) to account for estimation errors.
