A stock valuation tool answers one question: what is this business actually worth, so I know whether the price is a bargain or a bubble. The trap is that many tools spit out a single "fair value" number without showing the assumptions behind it, which makes the number useless (a DCF is only as good as its growth and discount-rate inputs). This post compares the 8 valuation tools that matter in 2026, with a heavy weight on transparency.
Disclosure: invest-like.com appears here and I built it. I have been clear about which pure-valuation tools go deeper on the math.
The 8 tools
1. Finbox - the transparent DCF
What it does: multiple valuation models (DCF, comparables, dividend discount) with visible, editable assumptions and analyst-estimate inputs.
Price: free tier, paid from around 20 USD/month.
Best for: investors who want to see and change every assumption in the model.
2. Alpha Spread - multi-method side by side
What it does: shows DCF, relative valuation and a Graham-style intrinsic value together, plus a worst-case scenario.
Price: free tier, paid from around 15 USD/month.
Best for: cross-checking one method against another quickly.
3. invest-like.com - valuation inside a full verdict
What it does: reports an intrinsic-value read and margin of safety as part of a seven-framework verdict, and tells you whether the business quality justifies paying up. Valuation never sits alone; it is paired with moat, balance-sheet and returns analysis.
Price: free tier, Pro 15 EUR/month.
Best for: investors who want the valuation contextualized by quality, not a lone number. Disclosure: I built it.
4. GuruFocus - DCF plus reverse DCF
What it does: a built-in DCF and a reverse DCF that shows what growth the current price implies, which is one of the most useful sanity checks in valuation.
Price: roughly 50 to 500 USD/year.
Best for: investors who like to ask "what is the market already assuming?"
5. Wisesheets - build your own model in a spreadsheet
What it does: pulls the historical data and estimates into Excel or Sheets so you build the valuation your way.
Price: roughly 60 to 100 USD/year.
Best for: modelers who do not trust a black-box fair value and want to own the math.
6. Simply Wall St - the visual fair value
What it does: a single fair-value estimate shown against the price, wrapped in the Snowflake.
Price: about 100 to 180 USD/year.
Best for: a fast visual read.
Weakness: single-method and not fully transparent.
7. TIKR - the data behind any valuation
What it does: the deep financials and estimates you feed into any model.
Price: around 15 USD/month.
Best for: the data source under your valuation, not the calculator itself.
8. gurufocus-style DCF calculators (free web tools)
What it does: many free web DCF calculators let you plug in growth and discount rate for a quick estimate.
Price: free.
Best for: a back-of-envelope check before committing to a paid tool.
Weakness: garbage in, garbage out; the free ones rarely pull clean data.
Which valuation method, which tool
| You want | Best tool |
|---|
| Editable, transparent DCF | Finbox |
| Several methods at once | Alpha Spread |
| What growth the price implies (reverse DCF) | GuruFocus |
| Valuation plus quality context | invest-like.com |
| Full control in a spreadsheet | Wisesheets + TIKR |
The most important rule with any valuation tool: a fair-value number you cannot audit is worthless. Favor tools that expose the assumptions, and always run at least two methods, because a DCF and a relative valuation that disagree are telling you something the single number hides.
Common questions
Which valuation method is most reliable? None on its own. DCF is sensitive to inputs, relative valuation inherits the market's mistakes, and asset-based methods miss intangibles. Triangulate across methods.
What is a reverse DCF and why does it matter? A reverse DCF solves for the growth rate the current price implies. If the market is pricing in growth the business cannot plausibly hit, that is a warning even without a full model.
Can I value a stock without a finance degree? Yes. The mechanics are simple arithmetic; the judgment is in the assumptions. See the walkthrough linked below.
Should the valuation number be the whole decision? No. Pair intrinsic value with business quality. A precise fair value on a fragile business is a precise way to be wrong.
