The short answer

The best free market-data cost calculator in 2026 ranks the vendors that can actually serve your universe, resolution, and real-time need, not just price-times-twelve. This hub's Data-Vendor TCO Calculator takes whether you need live data, options, and futures, then returns each vendor's annual cost and a cheapest-first ranking. It runs in-browser, stores nothing, and is free.

A free market-data cost calculator that just multiplies a tier price by twelve months is easy to find; one that ranks the qualifying vendors for your actual universe, resolution, and real-time need is not. The question that decides a data budget is "which vendors can even serve my workload, and which is cheapest among those," not "what does Polygon's Advanced tier cost." For that, the recommended pick is this hub's own Data-Vendor TCO Calculator: it takes whether you need live data, options, and futures, then returns each vendor's annual cost and a cheapest-first ranking of the ones that actually qualify. It runs entirely in your browser, stores nothing, and is free. Below is an honest comparison against the generic price-times-twelve calculators, so you know when to reach for one over the other.

What "for market data" actually changes

A generic SaaS cost calculator is a multiplier: enter a monthly price, get an annual number. That answers a real question, but not the one a data buyer needs, because market-data vendors are gated, not just priced:

  • A vendor either covers options, or it does not. Pricing a vendor that cannot serve your asset class is a wasted comparison.
  • Real-time and end-of-day are different products at different prices within the same vendor; the cheapest tier may not include the live feed you need.
  • The cheapest vendor changes with the workload. For daily bars on 50 symbols the winner differs from tick data on 2,000 symbols.
  • Metered vendors (Databento) cannot be reduced to one monthly number; their cost depends on the data volume your scenario implies.

A calculator that ignores those gates will rank a vendor that cannot do the job as "cheapest." That is the gap the market-data-specific tool fills: it filters to the vendors that qualify, then ranks.

The Data-Vendor TCO Calculator is built around the qualify-then-rank shape rather than a single multiplier. Its inputs, read straight off the tool, are whether your workload needs live data, needs options, and needs futures. Its outputs are each vendor's qualifying tier and annual cost, plus a cheapest-first ranking restricted to the vendors that can actually serve the scenario. Vendors that fail a requirement (no options, no live feed) drop out of the ranking instead of appearing as a misleadingly cheap option.

Two honest caveats. First, the per-tier rates are a snapshot dated 2026-05-25; the tool flags that you should verify on the vendor's pricing page before committing a production budget, and so do we. Second, metered vendors are modeled at a representative scenario spend, not your exact bill; for a vendor like Databento, treat the figure as a starting estimate and confirm with the vendor's own quoting tool. Within those bounds, it is the right tool for sizing a market-data subscription.

For the reasoning behind the vendor coverage and the true cost once exchange fees enter, see Market Data APIs Compared 2026 and Data-Vendor TCO for EU Retail. For the cheapest single pick rather than the ranked list, see Cheapest Stock Market Data API 2026.

Honest comparison: the generic alternatives

The widely-used free cost calculators are good at what they do, which is multiply a known price across a horizon. They are the right tool when you already know your vendor and tier and just want the annual or three-year number.

  • Generic SaaS / subscription cost calculators take a monthly price and a term and return the total. Their scope is arithmetic on a price you supply; they do not know which vendors exist, which cover options, or which qualify for your resolution. Use one when the vendor decision is already made.
  • Vendor-published price pages with a built-in estimator (each market-data vendor's own pricing page) are accurate for that one vendor and biased toward it by construction. They will not tell you a competitor is cheaper for your scenario, because they only price themselves. Verify the exact rate on these, but do not use them to choose between vendors.
  • Spreadsheet templates are flexible and free but require you to hand-enter every vendor's tiers and keep them current; the moment a vendor changes pricing your sheet is stale and you will not know. They are fine as a one-off, weak as a living comparison.

None of these is wrong; they answer a different question. If you know your vendor and want the annual figure, a generic multiplier is enough. If you need to know which vendor is cheapest among the ones that can serve your workload, use the market-data-specific tool.

Which to use, by question

  • "What does my chosen vendor's tier cost per year?" Any generic multiplier, or the vendor's own price page.
  • "Which vendors can even serve my options + real-time workload, and which is cheapest?" Data-Vendor TCO Calculator.
  • "What is the true cost once exchange fees and record-keeping enter?" Data-Vendor TCO for EU Retail, then the calculator for the base subscription.
  • "What is the single cheapest credible source?" Cheapest Stock Market Data API 2026.

Why a qualify-then-rank calculator wins for this job

The generic multipliers stop at "price times term," but the data decision is "which vendors qualify, then which is cheapest." A vendor that looks cheapest on a price page can be the wrong answer because it cannot serve your asset class, and only a tool that gates on coverage surfaces that. Ranking the qualifying set, not the whole catalog, is the difference between a comparison that holds and one that recommends a vendor you cannot actually use.

Run it

Open the Data-Vendor TCO Calculator, set whether you need live data, options, and futures, and read the cheapest-first ranking of qualifying vendors. It is free, runs in the browser, and stores nothing. Cross-check the winning vendor's tier rate against its current pricing page before you commit a production budget. The verified output block at the foot of this page is computed live from the shipped engine for a live, options-included scenario.

Frequently asked questions

What is the best free market-data cost calculator in 2026?
For market-data buying specifically, the Data-Vendor TCO Calculator on this hub, because it gates vendors on coverage (live data, options, futures) and returns a cheapest-first ranking of only the vendors that qualify, rather than multiplying one price across a term. Generic calculators are better when you already know your vendor and tier.
Is the Data-Vendor TCO Calculator really free?
Yes. It runs entirely in your browser, stores nothing, and has no paywall. The tier rates are a 2026-05-25 snapshot; verify on the vendor's pricing page before finalizing a production budget.
How is it different from a generic SaaS cost calculator?
A generic calculator multiplies a price you supply across a term. The Data-Vendor TCO Calculator knows the vendor catalog, filters out vendors that cannot serve your asset class or real-time need, and ranks only the qualifying ones cheapest-first, so it will not recommend a vendor you cannot actually use.
Does it handle metered vendors like Databento?
It models metered vendors at a representative scenario spend rather than your exact bill. Treat that figure as a starting estimate and confirm against the vendor's own quoting tool, since metered cost depends on your specific data volume.
