Plotly Graph

The chart compares projected EPS with discounted cash flow per share across the forecast period.

Example Data Table

This example shows a sample scenario using the default assumptions included in the calculator.

Current EPS	High Growth	High Years	Transition Years	Stable Growth	Required Return	Terminal P/E	Intrinsic Value
4.20	18.00%	5	3	4.00%	10.00%	22.00	$148.76

Formula Used

Projected Earnings:
EPS_t = EPS_t-1 × (1 + g_t)

Cash Flow Per Share:
Cash Flow_t = EPS_t × Payout Ratio

Discounted Cash Flow:
PV_t = Cash Flow_t ÷ (1 + r)^t

Terminal Value:
Terminal Value = EPS_n+1 × Terminal P/E

Intrinsic Value Per Share:
Intrinsic Value = Σ Discounted Cash Flows + Discounted Terminal Value + Net Cash Per Share

Alternative Justified P/E:
Justified P/E = Payout Ratio × (1 + g) ÷ (r - g)

This setup works well for growth companies because it separates fast expansion, a transition phase, and a mature stage with steadier assumptions.

How to Use This Calculator

Enter the current EPS for the company.
Set the early high-growth rate and how long it may last.
Add transition years to slow growth gradually toward maturity.
Enter a stable long-run growth rate below the required return.
Set the required return based on your expected investment hurdle.
Choose a payout ratio to convert earnings into shareholder cash flow.
Enter the terminal P/E you expect once growth normalizes.
Add cash, debt, and shares outstanding to capture net balance sheet value.
Use the margin of safety field to set a more conservative buy price.
Review the base case, justified P/E case, and sensitivity range together.

Frequently Asked Questions

1. What does this calculator estimate?

It estimates the fair value of a growth stock using projected earnings, payout assumptions, discounting, a terminal multiple, and balance sheet adjustments.

2. Why does it use multiple growth stages?

Fast-growing companies rarely keep the same growth rate forever. Multi-stage modeling reflects a realistic path from high growth to mature, slower expansion.

3. What is the required return?

Required return is the annual return you demand for owning the stock. It acts as the discount rate and strongly affects present value.

4. Why must stable growth stay below required return?

If stable growth equals or exceeds the discount rate, the long-run valuation formula becomes mathematically unstable and can produce unrealistic results.

5. What does payout ratio mean here?

Payout ratio converts earnings into cash flow per share. It can represent dividends, buybacks, or other shareholder distributions over time.

6. Why include cash and debt?

Cash increases equity value while debt reduces it. Adding net cash per share improves the final estimate for the stock’s equity value.

7. What is a good margin of safety?

Many investors use 15% to 30%, depending on uncertainty. Higher uncertainty usually calls for a larger discount between fair value and buy price.

8. Should I rely only on this valuation?

No. Use it with business quality, competition, management, debt profile, industry trends, and scenario testing before making a final investment decision.
