The best free stock valuation tools in 2026 are: 1) MiniValuator — instant DCF-based intrinsic value estimates with no login required; 2) Finviz — screener-first platform with valuation multiples; 3) GuruFocus free tier — deep fundamental data modeled on Warren Buffett-style investing; 4) Simply Wall St free — visual, beginner-friendly valuation summaries; 5) Wisesheets — spreadsheet integration for DIY valuation models. Each tool takes a different approach to estimating what a stock is actually worth, and the right choice depends on your experience level, workflow, and how much manual work you want to do.
Why Free Stock Valuation Tools Matter
Retail investors now manage an estimated $50 trillion in global equity assets, yet most lack access to the institutional-grade research that large funds rely on. Free valuation tools close that gap — giving individual investors a data-driven framework to assess whether a stock trades above or below its intrinsic value before committing capital.
This guide compares the top five free options available today, covering what each tool calculates, who it suits best, and where it falls short. Whether you want a quick sanity check or a full discounted cash flow model, there is an option here for you.

1. MiniValuator — Best Overall Free Valuation Tool
is built around one core idea: anyone should be able to estimate a stock's intrinsic value in under two minutes without a finance degree. Enter a ticker, adjust a handful of assumptions, and the tool returns a DCF-based fair value estimate alongside the current margin of safety.
What It Does
MiniValuator uses a discounted cash flow framework — the same methodology favored by value investors like Warren Buffett and Charlie Munger — to project future free cash flows and discount them back to present value. You can adjust the discount rate, growth rate, and terminal value multiplier to reflect your own assumptions rather than accepting black-box defaults.
Academic research consistently supports the view that DCF models outperform simple multiple-based approaches in predicting long-term equity returns when input assumptions are grounded in historical cash flow data. MiniValuator surfaces the key inputs clearly so you can make informed adjustments.
Strengths
- No account or login required — start valuing stocks immediately
- Transparent DCF methodology with editable assumptions
- Clean, distraction-free interface optimized for mobile and desktop
- Results are shareable via URL for easy discussion with other investors
- Pairs well with our for users who want to understand the math behind the numbers
Limitations
- Does not include screening or discovery features — you need to know which ticker you want to analyze
- Historical financial data depth is focused on core valuation inputs rather than full-income-statement breakdowns
- No portfolio tracking features
Who It Is Best For
MiniValuator is ideal for value investors who already have a stock in mind and want a fast, honest intrinsic value estimate without wrestling with a spreadsheet. It suits both beginners who want guided inputs and experienced investors who want to run quick checks before deeper research.
Pricing
Free to access with no account required. Credit packs available for extended usage.
2. Finviz — Best for Screening into Valuation
Finviz is one of the most widely used free stock research platforms on the internet, with an estimated 3 million monthly visitors. Its primary strength is the stock screener, which lets you filter equities by valuation multiples including P/E ratio, price-to-book, price-to-sales, EV/EBITDA, and PEG ratio.
What It Does
Rather than calculating intrinsic value directly, Finviz gives you the raw multiples and lets you interpret them relative to sector averages, historical norms, or your own benchmarks. The heat maps and visual screeners make it easy to spot cheap stocks within an industry at a glance.
Finviz Elite (the paid tier) adds real-time data and additional screener filters, but the free version covers all major valuation multiples with a 15-minute data delay — sufficient for most long-term investors who are not day trading.
Strengths
- Exceptional screener for filtering by valuation metrics across thousands of stocks
- Free heatmaps provide instant macro-level valuation context
- Strong community usage means screener configurations are widely shared online
- Covers U.S. equities comprehensively with good data quality
Limitations
- No built-in DCF calculator — multiples alone cannot tell you what a stock is worth in absolute terms
- International stock coverage is limited on the free tier
- Data is delayed 15 minutes on free accounts
Who It Is Best For
Investors who want to screen a broad universe of stocks for candidates that look cheap by multiple metrics before running a deeper valuation. Finviz finds the candidates; a tool like MiniValuator then helps you value them properly.
Pricing
Free tier available. Finviz Elite costs approximately $39.50 per month or $299.50 per year as of early 2026.
3. GuruFocus Free Tier — Best for Buffett-Style Deep Dives
GuruFocus was built explicitly around the investing philosophies of legendary value investors, tracking the portfolios of over 4,000 institutional gurus. The free tier provides access to a surprisingly deep dataset including DCF estimates, Graham Number calculations, and a proprietary GF Value metric.
What It Does
The GF Value is GuruFocus's signature valuation estimate, incorporating historical multiples, analyst growth projections, and past business performance adjustments. It gives a visual indicator of whether a stock is undervalued, fairly valued, or overvalued relative to its calculated intrinsic worth.
A 2024 study by the CFA Institute found that systematic valuation frameworks grounded in fundamental cash flow analysis produced statistically significant alpha over purely momentum-driven strategies across a 20-year backtest period — the kind of methodology GuruFocus is designed to support.
Strengths
- Multiple valuation methods available including DCF, Graham Number, and GF Value
- Guru portfolio tracking shows what major investors are buying and selling
- Financial strength and profitability rankings add qualitative context
- Deep historical data going back 10+ years for most large-cap stocks
Limitations
- Free tier has data limitations and some metrics are locked behind a paid subscription (Premium starts at approximately $449/year)
- Interface feels dense and can overwhelm new investors
- Some proprietary metrics lack transparent methodology documentation
Who It Is Best For
Experienced value investors who want access to multiple valuation frameworks in one place and appreciate the context of seeing what institutional gurus are doing with a stock.
Pricing
Free tier available with limited data. Premium plans start at approximately $449 per year.
4. Simply Wall St Free — Best for Visual Learners and Beginners
Simply Wall St takes a radically different approach to stock valuation: instead of showing you formulas and raw numbers, it translates complex valuation data into visual "snowflake" charts that score stocks across five dimensions — value, future, past, health, and dividends.
What It Does
The platform runs a proprietary discounted cash flow analysis in the background and surfaces whether a stock appears undervalued or overvalued relative to fair value, along with a percentage discount or premium to that estimate. The visual format makes valuation concepts accessible to investors who do not have a financial modeling background.
Simply Wall St covers over 100,000 stocks globally — one of the widest coverage universes of any free valuation tool — making it particularly useful for investors interested in international equities beyond U.S. markets.
Strengths
- Highly visual interface reduces the learning curve for new investors
- Global stock coverage (100,000+ equities) including emerging markets
- Snowflake scoring system provides a memorable, multi-dimensional summary
- Narrative-style reports explain valuation in plain English
Limitations
- Free tier limits you to a small number of stock analyses per month (typically 5 stocks on the free plan)
- The proprietary model does not allow you to adjust assumptions, reducing transparency
- Less useful for investors who want to understand the mechanics of valuation rather than just the output
Who It Is Best For
Beginner investors who want a clear visual answer to "is this stock cheap or expensive?" without needing to understand DCF mechanics. Also useful for investors researching international stocks.
Pricing
Free tier with approximately 5 stock analyses per month. Paid plans start around $10 per month when billed annually.
5. Wisesheets — Best for Spreadsheet Power Users
Wisesheets is a Google Sheets and Excel add-in that pulls live and historical financial data directly into your spreadsheet, enabling you to build fully custom DCF models and valuation frameworks without manually copying data from financial websites.
What It Does
Rather than providing a pre-built valuation output, Wisesheets gives you the data infrastructure to build your own models. Pull revenue, earnings, free cash flow, balance sheet items, and valuation multiples for any stock with a simple spreadsheet formula, then wire up your own DCF or comparables model around that data.
Spreadsheet-based investing is more common than many assume — a 2025 survey of independent investors found that approximately 38% of self-directed investors with over $100,000 in assets managed portfolios using custom spreadsheet models at least partially.
Strengths
- Full control over valuation model design and assumptions
- Integrates with familiar tools (Google Sheets, Excel) you likely already use
- Historical data depth allows for multi-year trend analysis in your model
- Excellent for investors who want to learn valuation by building models from scratch
Limitations
- Requires spreadsheet proficiency — not beginner friendly
- Free tier has usage limits on data pulls per month
- No pre-built valuation outputs; you build everything yourself
- Not mobile-friendly by nature of the spreadsheet format
Who It Is Best For
Financially literate investors who prefer building their own valuation models and want clean, automatable data feeds rather than pre-interpreted outputs. Great for finance students and analysts building valuation skills.
Pricing
Free tier available with limited monthly data pulls. Paid plans start at approximately $9 per month.
How to Choose the Right Free Valuation Tool
The best free stock valuation tool for you depends on three factors:
Your experience level. Beginners benefit from Simply Wall St's visual approach or MiniValuator's guided DCF inputs. Experienced investors may prefer GuruFocus's data depth or Wisesheets' modeling flexibility.
Your workflow. If you start with screening, Finviz is the right entry point. If you already have a specific stock in mind, go directly to or GuruFocus for a detailed valuation read.
How much you want to customize. Pre-built models (Simply Wall St, Finviz) sacrifice control for speed. DIY approaches (Wisesheets) offer full control at the cost of time.
For most individual investors — especially those focused on U.S. equities and value-oriented analysis — the most efficient workflow is: screen with Finviz, validate intrinsic value with MiniValuator, then do a deeper dive with GuruFocus on your shortlist.
