DCF Calculator: Discounted Cash Flow Valuation Model
Use this DCF calculator to estimate enterprise value, equity value, terminal value, and per-share value from projected free cash flow, WACC, terminal growth, exit multiple, net debt, and share count assumptions.
Before running a DCF, you need a discount rate. For unlevered free cash flow models, this is typically the Weighted Average Cost of Capital (WACC). The model supports multi-year free cash flow forecasts, WACC or discount rate assumptions, perpetual growth terminal value, net debt adjustments, and fully diluted share counts.

How to Build a DCF Valuation
Choose quick growth or year-by-year cash flows
Under Quick Growth mode, input starting Free Cash Flow (FCF) and a constant growth rate. The calculator will project FCFs automatically over 5-10 years. Under Year-by-Year mode, input custom FCF values for each individual forecast period to model fluctuating revenues.
Select a discount rate and terminal value method
Input a discount rate (typically WACC). Select Perpetuity Growth (Gordon Growth) to model infinite growth (typically 2%-3% long-term inflation rate), or Exit Multiple to assume the business is sold in the final year at a multiple of EBITDA, Revenue, or FCF.
Enter net debt and shares outstanding
To transition from Enterprise Value to Equity Value, input Net Debt (Total Debt minus Cash & Equivalents). Input preferred stock and minority interests if applicable. Provide total shares outstanding to compute the final intrinsic implied share price.
DCF Scenario Analysis
Change cash flow assumptions by scenario
Valuation is highly sensitive to forecasts. By calculating Bull (optimistic), Base (moderate), and Bear (pessimistic) assumptions, you avoid single-point estimates. Adjust annual growth, margins, and discount rates across scenarios to see the range of corporate value.
Compare enterprise and equity value ranges
Comparing scenario outputs maps your company's potential valuation spread. A wide gap between Bear and Bull highlights high risk or execution sensitivity, while a tight spread represents business stability and cash flow predictability.

DCF Sensitivity Analysis
Discount rate and terminal growth matrix
The 5x5 sensitivity matrix automatically cross-references the Hurdle Discount Rate against the Perpetual Growth Rate. This grids WACC adjustments (vertical) against perpetual terminal value growth (horizontal), calculating the implied per-share value of each intersection.
Discount rate and exit multiple matrix
When using the Exit Multiple method, the matrix swaps the growth axis for the exit multiple axis (e.g., 8x to 12x EBITDA). This helps corporate transaction leads determine fair transaction spreads and valuation hurdles under different acquisition multiples.
How to interpret invalid sensitivity cells
In perpetuity growth, WACC must be strictly greater than the terminal growth rate (WACC > g). If the discount rate is equal to or less than growth, the denominator is zero or negative, yielding an infinite valuation. The matrix labels these cells as "N/A" to ensure modeling logic safety.
DCF Formula
Present Value of FCF
Each period cash flow is discounted using compounding discount factors:
Perpetuity growth terminal value
The Gordon Growth model values the business beyond the forecast period using a steady perpetual growth rate:Terminal Value = FCF_n * (1 + g) / (r - g)This method assumes the business grows at rate (g) forever. The perpetual growth rate must be lower than the long-term economic GDP growth rate.
Exit multiple terminal value
The Exit Multiple method assumes the company is sold to a strategic buyer in the final forecast year:Terminal Value = Terminal Metric * Exit MultipleCommon metrics include EBITDA, Revenue, or final year FCF. Multiples are benchmarked against actual market transactions of comparable listed peers.
FCF Forecast Assumptions
Revenue growth
A DCF forecast usually starts with revenue growth. Growth should slow toward a sustainable long-term rate as the company matures, unless the model explicitly supports a temporary expansion phase.
Margin and reinvestment
Free cash flow depends on operating margin, taxes, capital expenditures, depreciation, and working capital. Strong revenue growth can still produce weak FCF if reinvestment needs are heavy.
Forecast length
Five to ten years is common for explicit forecasts. The forecast period should be long enough for the business to approach a normalized margin and growth profile before terminal value begins.
Terminal Value: Gordon Growth vs Exit Multiple
Gordon Growth method
Gordon Growth estimates terminal value from normalized final-year free cash flow, perpetual growth, and discount rate. It is internally consistent with cash flow fundamentals but highly sensitive to the spread between WACC and growth.
Exit multiple method
Exit multiple valuation applies a market multiple to a terminal metric such as EBITDA, revenue, or FCF. It is easier to benchmark against comparable companies but can import market-cycle assumptions into the model.
Discount Rate and WACC in DCF Models
Use WACC for unlevered FCF
If the DCF uses unlevered free cash flow, WACC is commonly used because the cash flows belong to all providers of capital before debt payments.
Match risk to cash flow
A higher-risk project, country, or early-stage company may require a higher discount rate than a mature company-wide WACC.
Check the value impact
DCF value can move sharply when WACC changes by even one percentage point, especially when terminal value is a large portion of enterprise value.
DCF Assumption Changes: Terminal Growth and Discount Rate
Terminal growth assumption changes
Terminal growth assumptions change when long-term inflation, industry maturity, reinvestment needs, market share limits, or competitive pressure change. A mature company with stable cash flow may support a lower, economy-like perpetual growth rate, while a company facing margin compression or shrinking demand may require a more conservative terminal growth assumption.
In a DCF model, terminal growth should normally remain below the discount rate and should be consistent with the company's long-term addressable market. Small changes can move enterprise value sharply because terminal value often represents a large share of total DCF value.
Discount rate assumption changes
Discount rate or WACC assumptions change when interest rates, credit spreads, equity risk premiums, leverage, beta, country risk, or company-specific risk change. A higher discount rate reduces the present value of future cash flows, while a lower rate increases present value.
Analysts should refresh WACC assumptions when a company issues debt, changes its capital structure, enters a riskier market, or faces a major shift in operating volatility. This calculator is an educational model, so assumption changes should be documented and sensitivity-tested rather than treated as investment advice.
From enterprise value to equity value
Subtracting net debt
Enterprise Value (EV) measures the value of corporate operations. To isolate value attributable to stock shareholders, we deduct corporate debt and add back surplus cash. This is formulated as deducting Net Debt (Total Debt minus Cash & Equivalents).
Adding non-operating adjustments
In corporate structures, non-operating assets (such as non-consolidated equity stakes, idle real estate assets, or treasury securities) must be added back to build an accurate bridge, while preferred stocks and minority interests are subtracted.
Calculating value per share
Once Equity Value is derived, divide it by the total outstanding common shares. This yields the intrinsic value per share. Comparing this intrinsic share price to the current market trading price highlights potential overvaluation or undervaluation.
DCF example calculation
Example cash flow assumptions
Let's evaluate a business with a starting Year 0 FCF of $100,000, growing at 8.00% annually for 5 years, with a discount rate (WACC) of 10.00%, and a perpetual growth rate (g) of 3.00%. Net debt is $200,000, and shares are 1,000,000.
Step-by-step present value calculation
Project Year 1-5 cash flows: $108,000; $116,640; $125,971; $136,049; $146,933. Discounting each yields the Present Value of Cash Flows: Sum of PV(FCFs) = $473,379.
Terminal value and valuation bridge
Terminal Value = $146,933 * 1.03 / (0.10 - 0.03) = $2,162,011. PV of Terminal Value is $1,342,439. Summing these yields an Enterprise Value (EV) of $1,815,818. Deducting Net Debt of $200,000 leaves an Equity Value of $1,615,818. Value per share is $1.62.
What your DCF result means
Why DCF produces a valuation range
A DCF does not produce a singular absolute figure; it generates a range of values. Because slight shifts in cash flows or rates cause wide valuations, analysts use a sensitivity matrix to establish floor and ceiling thresholds for investment margins of safety.
How WACC changes present value
WACC serves as the hurdle multiplier. A higher WACC lowers the present value of distant cash flows because of interest compounding. Companies with stable revenues enjoy lower WACCs, preserving remote cash flow values.
Why terminal value concentration matters
If over 70% of enterprise value rests on the Terminal Value, the valuation is heavily reliant on distant assumptions rather than immediate operations. A high TV concentration indicates elevated investment risk and a need to test exit assumptions carefully.
DCF use cases for SaaS, private companies, and small businesses
SaaS free cash flow assumptions
SaaS models feature deferred cash revenues and high upfront customer acquisition costs (CAC). Standard EBITDA models fail to capture cash dynamics. Projections rely on customer lifetime value (LTV), churn rates, and growth margins to compute true cash profiles.
Private company discount-rate limitations
Private companies lack publicly observable stock betas. To derive the appropriate discount rate, analysts compile public peers, calculate their average asset beta, and relever that benchmark to the private firm's debt-to-equity ratios.
Small business normalization adjustments
Small business statements contain non-operating expenditures or owner-operator salary anomalies. Before modeling FCFs, adjust accounting records to state normalized earnings as if a professional third-party manager were running operations.
- Levered vs. Unlevered cash flows: Mixing levered cash flows with WACC (unlevered discount rate), which double-counts interest benefits.
- Inconsistent discount rates: Changing the discount rate annually without factoring in capital structure transitions.
- Terminal growth rate anomaly: Setting perpetuity growth (g) higher than long-term GDP inflation rate (typically > 3.5%).
- Double-counting assets: Leaving cash balance in adjustments while it is already included in Net Debt deductions.
Real-world case study: Apple Inc. (AAPL, FY 2023)
Apple Inc. metrics profile
Apple Inc. (AAPL) is a global technology leader, and its robust financial performance makes it a prime candidate for a Discounted Cash Flow (DCF) valuation. Analyzing its recent financial data provides insights into its cash-generating capabilities and future growth prospects, essential for investors to assess its intrinsic value.
Apple's substantial Free Cash Flow of $99.584 billion in FY 2023 highlights its strong operational efficiency and ability to generate significant cash after accounting for operating expenses and capital investments. This cash flow, combined with a projected revenue growth rate of 8%, an effective tax rate of 14.7%, and a WACC of 8.35%, forms the critical basis for a Discounted Cash Flow valuation. A DCF analysis for Apple would involve projecting these cash flows into the future, discounting them back to the present using the WACC, and adding a terminal value based on the long-term growth assumption. This approach helps investors determine the intrinsic value of Apple's stock, providing a fundamental perspective beyond market price fluctuations.
