DCF Calculator - Cash Flow Valuation

The DCF calculator estimates what a business may be worth today by discounting projected free cash flow and a terminal value back to present value. Use it when reviewing a stock, comparing acquisition assumptions, checking a private-company estimate, or stress-testing a long-term investment case. The result is an estimate built from assumptions, so it should start a valuation discussion rather than end one.

• • Stock valuation: Estimate intrinsic value per share from free cash flow, net debt, and diluted shares before comparing the result with the current market price.
• • Acquisition screening: Translate operating cash-flow assumptions into enterprise value before discussing debt, cash, and offer price.
• • Scenario review: Change growth, discount rate, or terminal growth to see which assumption drives most of the valuation.
• • Investment memo support: Use a compact model to document the cash-flow logic behind a buy, hold, sell, or pass decision.

A discounted cash flow model is most useful when a company has cash flows that can be connected to revenue, margins, reinvestment, and capital structure. It is weaker for businesses with unpredictable survival risk, unresolved financing needs, or cash flows that swing from one-time events.

Read the per-share answer beside the terminal value share and margin of safety. A valuation that depends mostly on terminal value is not automatically wrong, but it is more sensitive to small changes in long-run growth and required return.

When you need a cost-of-equity input before setting the discount rate, the CAPM Calculator can support that assumption.

The calculator uses a two-stage free cash flow model: an explicit annual forecast followed by a perpetual-growth terminal value.

• FCF_t: Projected free cash flow in forecast year t.
• r: Discount rate or WACC used to present value cash flows.
• g: Terminal growth rate after the explicit forecast period.
• n: Number of explicit forecast years.
• Net debt: Debt minus cash, subtracted from enterprise value to estimate equity value.
• Shares: Diluted shares outstanding used to convert equity value into value per share.

The explicit forecast handles the years you can model with some detail. The terminal value represents cash flows after that period, so it often carries a large share of enterprise value. The DCF calculator reports that share to make the dependency visible.

After enterprise value is calculated, net debt adjusts for financing claims. Positive net debt reduces equity value; net cash increases equity value because the net debt input can be negative.

According to CFA Institute, FCFF valuation estimates firm value as the present value of future FCFF discounted at WACC, then equity value is firm value minus debt.

If you want the return rate implied by a series of cash flows instead of a present-value estimate, use the IRR Calculator alongside this model.

A useful DCF is less about one answer and more about whether each assumption matches the business being valued.

Do not use net income as a direct substitute for free cash flow unless the business has unusually clean accounting and low reinvestment needs. Working capital, capital spending, taxes, and financing structure can make accounting earnings differ sharply from cash that owners can use.

If you are valuing a bank, insurer, commodity explorer, or early-stage company, a simplified FCFF model may need adjustment. Regulated balance sheets, reserve life, funding risk, or negative cash flow can make a different valuation method more defensible.

For a debt-capacity check before applying the equity bridge, the Cash Flow to Debt Calculator compares cash flow with debt obligations.

Enter assumptions in millions so the DCF calculator keeps enterprise value and equity value outputs on the same scale.

1. 1 Normalize starting free cash flow: Use a run-rate or average free cash flow figure that removes one-time items you do not expect to repeat.
2. 2 Set forecast growth: Choose a growth rate that fits revenue, margin, reinvestment, and competitive position rather than a preferred valuation answer.
3. 3 Choose a discount rate: Use WACC for enterprise value, or another required return if your model is intentionally simplified.
4. 4 Keep terminal growth restrained: Use a long-run rate below the discount rate and test how much the answer changes when the rate moves.
5. 5 Bridge to per-share value: Enter net debt and diluted shares so the model can convert enterprise value into intrinsic value per share.
6. 6 Compare with price: Add the current market price only after reviewing the assumptions so the price does not steer the model.

A memo might use $250 million of normalized free cash flow, 4% forecast growth, a 9% discount rate, 2% terminal growth, $600 million of net debt, and 80 million shares. If the per-share value is only slightly above price, rerun the model with lower growth or higher discount rate before treating the spread as meaningful.

When your investment cash flows arrive on irregular dates, the XIRR Calculator is a better return check than an annual DCF forecast.

A compact DCF model gives structure to an investment view that might otherwise rely only on price multiples.

• • Separates operations from financing: Enterprise value shows the cash-flow value of the business before the net debt bridge to common equity.
• • Makes assumptions auditable: Growth, discount rate, terminal growth, debt, and share count are visible inputs that can be challenged.
• • Highlights terminal dependence: The terminal value share shows whether most of the answer comes from the years after the detailed forecast.
• • Supports scenario work: Changing one assumption at a time helps identify whether the thesis rests on growth, risk, debt, or share count.
• • Connects value to price: The margin-of-safety output translates a model estimate into a practical market-price comparison.

The calculator is intentionally simple enough to audit. A full valuation model may forecast revenue, margins, taxes, depreciation, capital spending, and working capital separately, but the same present-value logic still applies.

Use the result with peer multiples, return analysis, balance-sheet review, and business-quality judgment. A DCF answer that conflicts with every other signal deserves another look at assumptions before it guides capital allocation.

To add a simple cash-recovery view beside long-run value, the Payback Period Calculator shows how quickly an investment earns back its initial cost.

Small assumption changes can move a DCF calculator result sharply, especially when terminal value is a large share of enterprise value.

• • This model applies a single annual growth rate during the explicit forecast. A detailed company model should usually separate revenue, margin, tax, capital spending, and working-capital drivers.
• • The terminal value uses a perpetual-growth method. It is less suitable when the company is shrinking permanently, exposed to finite reserves, or unlikely to reach stable economics.
• • The calculator does not provide investment advice, tax advice, or a fairness opinion. It is a calculation aid for reviewing assumptions.

For public companies, use diluted shares and a balance-sheet date that matches the cash-flow base. For private businesses, be explicit about whether owner compensation, related-party expenses, or excess cash were normalized before entering free cash flow.

When the terminal value share is very high, run downside cases. If a small increase in discount rate or a small decrease in terminal growth erases the margin of safety, the valuation needs stronger evidence before it supports a decision.

According to NYU Stern valuation notes, discounted cash flow value is the sum of expected cash flows discounted by a rate appropriate for the riskiness of those cash flows.

If a financing assumption changes the required return, the Cost of Capital Calculator helps connect debt cost, equity cost, tax rate, and capital mix to a valuation discount rate.
