The Cost of Equity Calculator helps you estimate the return required by investors to invest in a company's stock. It's based on widely accepted models like the Capital Asset Pricing Model (CAPM) and the Dividend Discount Model (DDM).
This metric is crucial for stock valuation, portfolio analysis, and investment decision-making.

Cost of equity is essential in evaluating whether a stock provides enough return for the risk it carries. It's also a key component in:
Discounted Cash Flow (DCF) models
Comparing companies
Assessing funding costs
Knowing a company's cost of equity helps you decide whether it's worth the investment.
Yes, this calculator is completely free and available to anyone.
There's no sign-up required; just enter your inputs and calculate.
You can choose from two standard formulas:
CAPM (Capital Asset Pricing Model):
Cost of Equity = Rf + β × (Rm - Rf)
Where:
Rf = Risk-free rate
β = Stock beta
Rm = Expected market return
Dividend Discount Model (Gordon Growth Model):
Cost of Equity = (D1 / P0) + g
Where:
D1 = Next year's expected dividend
P0 = Current share price
g = Expected dividend growth rate
Use CAPM if the company doesn't pay regular dividends or if you want a broader market-based view.
The calculator applies well-established financial models. Its accuracy depends on the quality of your input data.
For the best results, use up-to-date values from reliable sources like:
Yahoo Finance
Google Finance
Company investor relations pages
Here's where to look for each input:
Beta: Found on most finance sites under the stock's summary page
Risk-free rate: Use current yield on 10-year U.S. Treasury bonds
Market return: Typically 8–10% (based on historical averages)
Dividend and share price data: Use Yahoo Finance, Google Finance, or company websites
Use the calculator above to find the cost of equity for any stock. Whether you're valuing a business or analyzing your portfolio, this tool gives you a fast and reliable way to get started.
