Idea 1 of 4

Find the cash before forecasting it.

A discounted cash flow model turns future cash into a value today. Start with a defensible cash-flow base, forecast it, discount each future payment and add the value of later years. The answer changes when the assumptions change.

Coca-Cola’s 2025 cash-flow statement reports $7,408 million of operating cash flow and $2,112 million of capital spending. Subtracting gives $5,296 million of reported free cash flow. Its earnings release also excludes a $6,100 million fairlife acquisition-related payment, producing $11,396 million. Source 1 · Source 2.

Simplified cash-flow base$12,082M
All amounts in millions of dollars. Reported and company-adjusted cash are different measures. The final $686M is this lesson’s assumption, not a company-reported cash-flow line.
How should cash flow and the discount rate match?

Match the claim An operating-business DCF uses cash available to debt and equity investors, discounted at the weighted average cost of capital (WACC). Cash flow to equity uses the cost of equity and must include the effect of net borrowing; operating cash flow less capital spending alone is not automatically FCFE.

Keep the shortcut visible This lesson preserves its simplified base: $11,396M + ($1,654M interest expense − $786M interest income) × (1 − 21%) ≈ $12,082M. It uses a net-interest proxy and an assumed tax rate. A full valuation would reconcile operating cash flow, financing, nonoperating investments and their tax effects more carefully.

Remember this

A cleaner forecast cannot rescue an unsuitable cash-flow base.

Idea 2 of 4

Turn future cash into today’s value.

Forecast first. Discount second. In the original lesson’s simplified Coca-Cola model, the $12,082M base grows 4% annually for five years. Each year-end cash flow is divided by (1 + discount rate)year. These are teaching assumptions, not management guidance or a current appraisal.

The model uses 6.33% WACC, the January 2026 soft-drinks industry figure in Damodaran’s data, as an illustrative input. Its 2.5% perpetual growth assumption values cash after year 5. The terminal value is calculated at year 5 and then discounted back too. Source 3 · Source 4.

Five forecast years · present value$56.6B
Later years · present value$289.4B

Most of this model’s value comes from cash beyond the explicit forecast.

Enterprise value$345,980M
Assumed net debt$29,686M
Simplified equity value$316,294M
Divide by 4,313M diluted shares$73.34 per share
Model result
not a price target
Model valued at the end of 2025. Five year-end payments, 4% forecast growth, 6.33% discount rate and 2.5% perpetual growth. Totals use unrounded cash flows; displayed figures are rounded.
What is terminal value, and where does it sit?

At the forecast horizon Terminal value = year 6 cash flow ÷ (WACC − perpetual growth). Here year 5 cash is about $14,699M, so year 6 cash is about $15,067M and terminal value is about $393,387M at year 5.

Bring it back to today Divide that terminal value by 1.06335 to get about $289,429M today. Perpetual growth must stay below the discount rate and must be sustainable for a mature business. Source 4.

What is missing from this simplified equity bridge?

Debt, cash and shares The original model nets $45,492M of borrowings against $15,806M of cash and liquid investments. It uses 4,313M average diluted shares from 2025. A valuation at another date needs updated, consistent inputs. Source 1.

Other claims and assets A full appraisal also considers nonoperating assets, investment stakes, minority interests, leases, dilution and other claims where relevant. Avoid counting investment income and investment values twice. The simplified bridge is an arithmetic lesson, not a complete valuation.

Remember this

Discount the terminal value, then bridge carefully from business value to shareholders.

Idea 3 of 4

Stress test the assumptions.

One answer can conceal a wide range. Hold the base, five-year growth, net debt, shares and 2.5% terminal growth fixed. Changing only WACC by one percentage point produces the three model values below.

Compare that with changing forecast growth from 4% to 3% or 5% at the base WACC: about $69.80 and $77.00 per share. Here the discount-rate change moves the answer much more. That finding belongs to this model, not every DCF.

Lower required return$101.81WACC 5.33%
Original assumption$73.34WACC 6.33%
Higher required return$56.65WACC 7.33%
The cash forecast stayed the same. The valuation did not.

A smaller gap between WACC and perpetual growth increases terminal value sharply.

Sensitivity illustration from the same simplified model. Only WACC changes; all other inputs stay fixed. Bar heights are proportional to the displayed per-share model values.
How does a margin of safety fit?

Show the uncertainty first Write a cautious, base and optimistic case. Record what changes and why. A margin of safety is a gap between an estimated value and a price; it does not make the estimate correct.

Simple arithmetic For a hypothetical $100 value estimate, a 30% discount corresponds to $70. A poorly supported $100 estimate does not become reliable because you multiply it by 70%. Test the underlying cash flow, growth, rate and terminal assumptions.

Remember this

Treat the result as a scenario to challenge, not a number to believe.

Idea 4 of 4

Try the model yourself.

Change one input at a time. This local model reproduces the lesson’s simplified arithmetic. It uses the unrounded $12,081.72M base (displayed as $12,082M), includes five year-end cash flows, deducts $29,686M net debt and divides by 4,313M shares. Dollar outputs are in millions except the per-share result.

What changes the DCF?

Teaching model · no trade
Forecast years · present value$56,552M
Later years · present value$289,429M
Enterprise value$345,980M
Simplified value per share$73.34

About 84% of the enterprise value comes from the terminal value.

  1. Change WACC to 5.33%, then 7.33%. Explain why the price estimate moves while the cash forecast stays fixed.
  2. Restore 6.33%. Change five-year growth to 3%, then 5%, keeping perpetual growth fixed.
  3. Restore 4%. Set perpetual growth equal to WACC and read the validation message. Explain why the formula cannot use that pair.
Open the DCF Valuation Tool →

This model illustrates assumptions, not current fair value. The separate tool uses revenue and operating inputs; follow its field labels and check the cash-flow and net-debt treatment before comparing results. Local practice and reading ticks do not record LMS completion.

What should you record before valuing a real business?

Build an input record Note the filing date, valuation date, units, cash-flow definition, adjustments, forecast horizon, growth assumptions, discount-rate basis, net debt and share count. Check several years rather than choosing the most convenient year.

Write a reason to reconsider State which assumption drives the result and what evidence would change it. If the business does not fit a stable positive-cash-flow model, use a more suitable method rather than forcing a precise-looking answer.

Remember this

Keep the inputs, sources and limitations beside the answer.

Question 1 of 3

Coca-Cola’s 2025 10-K shows $7,408 million of operating cash flow and $2,112 million of purchases of property, plant and equipment. What was free cash flow before any adjustment?

Why can a small rate change move a DCF so much?

A narrow denominator Terminal value divides the next cash flow by WACC minus perpetual growth. Here that gap is 3.83 percentage points. Lowering WACC by one point reduces the gap to 2.83 points.

A large terminal component About 84% of the base model enterprise value comes from the discounted terminal value. Changing its denominator and discount factor therefore has a large effect on the final estimate.

Review your takeaway card and the learning path
  • Find the right base. Reported cash and adjusted cash answer different questions.
  • Match cash and rate. Avoid mixing the business and equity approaches.
  • Discount every part. Terminal value belongs at the forecast horizon first.
  • Challenge the result. Keep a range, sources and limitations beside the estimate.
