MiniValuator is a free online stock valuation calculator using Discounted Cash Flow (DCF) and Price-to-Earnings (PE) ratio analysis, designed for individual investors, financial analysts, and finance students. It calculates the intrinsic value of US-listed stocks using a two-stage stock valuation model.
MiniValuator was built out of a personal frustration. As a value investor running DCF models in spreadsheets, I found the process unnecessarily time-consuming — rebuilding the same formulas for every new stock, manually adjusting growth assumptions, and struggling to visualize how small changes in inputs cascaded into dramatically different stock valuations. I wanted a stock valuation tool that was fast, transparent about its methodology, and designed for investors who actually understand what they're doing — not a black-box algorithm that spits out a number without explanation. That's the tool I built.
Charlie Wang is a value investor and software developer based in Asia. He has been studying and practicing the fundamental analysis principles taught by Benjamin Graham, Warren Buffett, and Aswath Damodaran for over a decade. He writes about value investing, stock analysis, and market observations in his Substack newsletter (nicheseeker.substack.com) and Chinese investment community on Xiaohongshu. MiniValuator is his attempt to build the stock valuation tool he always wished existed: fast, methodologically transparent, and free.
MiniValuator is built around two core stock valuation methods used by professional investors and equity analysts worldwide. The Discounted Cash Flow (DCF) method estimates intrinsic value by projecting a company's future free cash flows and discounting them back to present value using the Weighted Average Cost of Capital (WACC). This stock valuation method, formalized by John Burr Williams in 1938 and popularized by Warren Buffett, remains the gold standard for fundamental stock valuation. The Price-to-Earnings (PE) ratio method provides a faster, relative valuation by comparing a stock's earnings multiple to industry peers and historical norms — useful for quickly assessing whether a stock is over or undervalued relative to comparable companies.
We believe stock valuation is as much art as science. No stock valuation model gives you the "right" answer — that's why MiniValuator's sensitivity heatmap shows you a range of intrinsic values across different growth and discount rate assumptions. The goal isn't a precise number; it's to understand whether a stock has a meaningful margin of safety at current prices.
