📌 Quick Answer: A DCF calculator estimates intrinsic value by discounting future cash flows back to present value. For a company with $1M current FCF, 10% growth for 5 years, 9% WACC, and 2.5% terminal growth: enterprise value ≈ $19.5M. If net debt is $500K and shares outstanding are 1M, intrinsic value per share ≈ $19.00.
📋 Key Takeaways — DCF Valuation at a Glance
DCF = Present Value of future cash flows + Present Value of terminal value
WACC (discount rate) for most US companies: 7-10%
Terminal growth rate should not exceed 2-3% (US GDP growth)
Terminal value often represents 60-80% of total enterprise value
Small assumption changes dramatically alter valuation (sensitivity)
Intrinsic value = Equity Value ÷ Shares Outstanding
Margin of safety: buy only if price is 20-30% below intrinsic value

Result: EV $189M | TV% 82% | Buy if price below $151M

What is a DCF Calculator and How Does It Work?
A DCF calculator is a financial modeling tool that estimates the intrinsic value of an investment by projecting future cash flows and discounting them back to present value. Our DCF calculator 2026 uses the standard discounted cash flow methodology used by professional investors, investment banks, and equity analysts worldwide. The calculator answers the fundamental question of valuation: "What is this company worth today based on its future cash-generating ability?"
How does the discounted cash flow calculator work? Enter your current free cash flow (FCF), expected growth rate, projection period, discount rate (WACC), and terminal growth rate. The calculator instantly computes the present value of projected cash flows, the terminal value, the total enterprise value, equity value, and intrinsic value per share.
Where: FCFt = free cash flow in year t; WACC = weighted average cost of capital (discount rate); n = number of projection years; Terminal Value = FCFn × (1 + g) / (WACC - g); g = terminal growth rate.
Equity Value = Enterprise Value - Net Debt.Intrinsic Value Per Share = Equity Value ÷ Shares Outstanding.
Understanding WACC (Weighted Average Cost of Capital)
WACC is the required rate of return that a company must earn to satisfy all its investors (both debt and equity holders). It represents the time value of money and risk. Typical WACC ranges:
Large-cap US stocks: 7-9%
Mid-cap US stocks: 9-11%
Small-cap US stocks: 11-14%
High-risk/emerging companies: 15-20%+
A higher WACC means future cash flows are worth less today, resulting in a lower valuation.
Terminal Value: The Most Important Number
Terminal value represents the value of all cash flows beyond the projection period. In most DCF models, terminal value accounts for 60-80% of total enterprise value. This makes the terminal growth rate assumption critical. Best practices:
Never use terminal growth above 3% — no company can grow faster than GDP forever.
Terminal growth should be below WACC — otherwise the formula breaks down (negative denominator).
Match inflation — 2-2.5% is a common realistic assumption for US companies.
Limitations of DCF Analysis
DCF is a powerful tool but has important limitations. Sensitivity to assumptions: A 1% change in WACC or growth rate can change valuation by 20-30%. Predictability requirement: DCF works best for stable companies with predictable cash flows (utilities, consumer staples). Growth stocks are harder: Early-stage companies with negative or volatile cash flows are difficult to value with DCF. Terminal value dependency: With 60-80% of value from terminal assumptions, the model is only as good as its long-term growth estimate.
How to Use DCF in Investment Decisions
Step 1: Calculate intrinsic value per share using conservative assumptions.
Step 2: Compare to current market price.
Step 3: Require a margin of safety (typically 20-30%) before buying.
Step 4: Run sensitivity analysis with different WACC and growth rates to see the valuation range.
Step 5: Combine with other valuation methods (P/E multiples, EV/EBITDA) for a complete picture.
❓ Frequently Asked Questions
What is a DCF calculator?
A DCF (Discounted Cash Flow) calculator estimates the intrinsic value of an investment by projecting future cash flows and discounting them back to present value using WACC. It is the most widely used valuation method by professional investors and analysts.
What is the DCF formula?
DCF = Σ [CFt / (1 + r)^t] + [Terminal Value / (1 + r)^n]. Where CFt is cash flow in year t, r is the discount rate (WACC), and Terminal Value = FCFn × (1 + g) / (WACC - g).
What discount rate should I use for DCF?
The discount rate should be your Weighted Average Cost of Capital (WACC). Typical WACC for large US companies is 7-10%. Higher risk companies warrant higher discount rates (10-15%).
What terminal growth rate is appropriate?
Terminal growth rate should not exceed the long-term GDP growth rate of the economy, typically 2-3% for the US. Using rates above 3% is generally considered unrealistic and will inflate valuations.
What is the difference between enterprise value and equity value?
Enterprise Value (EV) = Equity Value + Debt - Cash. EV represents the total value of the business. Equity Value is what shareholders own after debt is repaid. To get per-share value, divide equity value by shares outstanding.
What are the limitations of DCF analysis?
DCF is highly sensitive to assumptions about growth rates, discount rates, and terminal values. Small changes can dramatically alter valuations. It also assumes predictable cash flows, making it less useful for early-stage or highly cyclical companies.
💡 Expert Tips for DCF Modeling
Tip #1: Use conservative assumptions (lower growth, higher WACC) to build in a margin of safety.
Tip #2: Run sensitivity analysis with a range of WACC (7-12%) and terminal growth (0-3%) — the resulting valuation range is more useful than a single number.
Tip #3: If terminal value is more than 85% of enterprise value, your projections may be too short or terminal growth too aggressive.
Tip #4: Cross-check your DCF against trading multiples (P/E, EV/EBITDA) and transaction comps to sanity-check your result.
