Stock Price Calculator
Calculate the intrinsic value of any stock using the Discounted Cash Flow (DCF) model.
Intrinsic Value Per Share
Formula: Intrinsic Value = Σ [EPS * (1+g)^n / (1+r)^n] + [Terminal Value / (1+r)^n]. This Stock Price Calculator uses a multi-stage DCF model to discount future earnings back to today's value.
Earnings Projection vs. Present Value
Green bars represent projected EPS; Blue bars represent the Present Value of those earnings.

What is a Stock Price Calculator?
A Stock Price Calculator is an essential financial tool used by investors to estimate the "fair" or intrinsic value of a company's stock. Unlike the market price, which fluctuates based on supply and demand, the intrinsic value calculated by a Stock Price Calculator is based on the fundamental ability of a company to generate cash flows or earnings in the future.
Investors use this Stock Price Calculator to determine if a stock is undervalued, overvalued, or fairly priced. If the intrinsic value is significantly higher than the current market price, the stock may be considered a "buy." Conversely, if the Stock Price Calculator shows a value lower than the market price, it might be a signal to sell or avoid the investment.
Common misconceptions include the idea that a Stock Price Calculator can predict the exact future price. In reality, it provides a mathematical estimate based on your assumptions about growth and risk. Using a Stock Price Calculator requires careful input of data to ensure the output is reliable for decision-making.
Stock Price Calculator Formula and Mathematical Explanation
The core logic behind this Stock Price Calculator is the Discounted Cash Flow (DCF) model applied to Earnings Per Share (EPS). The formula breaks down into two main parts: the projection period and the terminal value.
The Formula:
Intrinsic Value = [Σ (EPSn / (1 + r)n)] + [TV / (1 + r)N]
Where:
- EPSn: Earnings per share in year n.
- r: Discount rate (required rate of return).
- TV: Terminal Value, calculated as [EPSN * (1 + gt) / (r – gt)].
- gt: Terminal growth rate.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Current EPS | Last 12 months earnings per share | Currency ($) | Varies by company |
| Growth Rate | Expected annual growth for 5-10 years | Percentage (%) | 5% – 25% |
| Discount Rate | Investor's required annual return | Percentage (%) | 7% – 12% |
| Terminal Rate | Growth rate in perpetuity (inflation-like) | Percentage (%) | 2% – 4% |
Practical Examples (Real-World Use Cases)
Example 1: High-Growth Tech Stock
Imagine a tech company with a current EPS of $2.00. You expect it to grow at 20% for the next 10 years. You require a 10% return, and you assume a 3% terminal growth rate. By entering these into the Stock Price Calculator, you might find an intrinsic value of $115.40. If the stock is trading at $80, the Stock Price Calculator suggests it is undervalued.
Example 2: Stable Utility Company
A utility company has an EPS of $4.00 with a slow growth rate of 4%. Using a discount rate of 8% and a terminal growth of 2% in the Stock Price Calculator, the intrinsic value might come out to $72.50. If the market price is $90, the Stock Price Calculator indicates the stock is currently overvalued relative to its earnings potential.
How to Use This Stock Price Calculator
- Enter Current EPS: Find the most recent diluted EPS from the company's financial statements.
- Input Growth Rate: Research analyst estimates or historical averages to project future growth.
- Set Discount Rate: This is your "hurdle rate." Most investors use 10% as a baseline for the stock market.
- Define Terminal Rate: This should generally be close to the long-term GDP growth or inflation rate (2-3%).
- Select Years: Choose how many years you want to project high growth before the company reaches a steady state.
- Analyze Results: The Stock Price Calculator will instantly update the intrinsic value and provide a detailed year-by-year breakdown.
Key Factors That Affect Stock Price Calculator Results
- Earnings Accuracy: The Stock Price Calculator relies heavily on the starting EPS. One-time charges or gains can distort this.
- Growth Estimates: Small changes in the growth rate input in the Stock Price Calculator lead to massive changes in the final valuation.
- Discount Rate Sensitivity: A higher discount rate reduces the present value. This reflects higher risk or higher opportunity cost.
- Terminal Value Weight: Often, over 60% of the value in a Stock Price Calculator comes from the terminal value, making the terminal growth rate critical.
- Economic Cycles: The Stock Price Calculator assumes linear growth, but real-world earnings often fluctuate with the economy.
- Margin of Safety: Professional investors always apply a "margin of safety" (e.g., 20% discount) to the result provided by the Stock Price Calculator to account for errors.
Frequently Asked Questions (FAQ)
What is the most important input in the Stock Price Calculator?
While all inputs matter, the growth rate and discount rate have the most significant impact on the Stock Price Calculator output due to the nature of exponential compounding.
Can I use this Stock Price Calculator for companies with negative EPS?
No, the standard DCF model used in this Stock Price Calculator is not suitable for companies with negative earnings. You would need a more complex model that projects when the company becomes profitable.
Why is the terminal growth rate so low?
In a Stock Price Calculator, the terminal rate cannot exceed the growth of the overall economy (GDP) indefinitely, or the company would eventually become larger than the entire economy.
How often should I update my Stock Price Calculator inputs?
It is best to update your Stock Price Calculator after every quarterly earnings report or when significant macroeconomic shifts occur.
Does this Stock Price Calculator account for dividends?
This specific Stock Price Calculator focuses on earnings. However, since dividends are paid out of earnings, the intrinsic value reflects the total capacity to pay shareholders.
What discount rate should I use in the Stock Price Calculator?
Many investors use the WACC (Weighted Average Cost of Capital) or a flat rate like 10% to represent the historical average return of the S&P 500.
Is the Stock Price Calculator result a guarantee?
Absolutely not. The Stock Price Calculator provides a theoretical value based on assumptions. Market sentiment and unforeseen events can drive prices elsewhere.
What is a "Margin of Safety" in the context of this calculator?
It is the practice of only buying a stock if the market price is significantly lower (e.g., 20-30% lower) than the value shown by the Stock Price Calculator.
