Celsmar and Koyfin, with both price lists open
Both cover the same job —look at a company, its accounts and its chart— and arrive at it from different places. Here are the figures for both, with the date they were taken and a link to the page that publishes them.
Koyfin figures taken from their pricing page on 18 September 2026. Celsmar figures from its pricing page.

Where each figure comes from
Koyfin's are taken from their own pricing page on 18 September 2026, and they are the ones published without signing up: Free $0, Plus $39, Premium $79, Advisor Core $209 and Advisor Pro $299 a month, with an announced discount of up to 30% on annual billing whose exact amount is not broken down.
Celsmar's are on its pricing page: Free €0, Pro €9.99/month —€95.90 a year— and Enterprise €49/month. The two price lists are in different currencies and are deliberately not converted here: the day's exchange rate is not a product fact.
The difference that is not about price
Koyfin covers more than 100,000 companies; Celsmar covers eight indices. That is a whole order of magnitude and it belongs before anything else: if the stock you are looking for is not in those eight indices, it is not in Celsmar.
In exchange, inside those eight indices Celsmar takes European fundamentals from the statements companies file with their regulator —CNMV, ESEF, EDGAR— back to 2005, and shows which line every figure comes from. These are two different readings of coverage: one wide, one deep.
What one does and the other does not
Koyfin has a whole product line for financial advisors: model portfolios, client proposals and reports, custodian integration. Celsmar has none of that and it is not on its roadmap.
Celsmar has AI reports with a monthly quota —5 a month on the free plan, 50 on Pro— exportable to PDF, portfolio audit, Monte Carlo and VaR, and five market desks with sovereign debt from 54 countries. None of those appear in Koyfin's price list.
When to choose Koyfin over Celsmar
- If the stock you follow is not in the S&P 500, the Nasdaq 100, the Dow, the Russell 2000, the IBEX 35, the DAX 40, the STOXX 600 or the FTSE 350. With 100,000+ snapshots, the odds Koyfin has it are far higher.
- If analyst estimates are your raw material and you need a long series. Koyfin publishes 10 years of estimates from the $39 plan; Celsmar gives consensus and revisions, not that series.
- If you are a financial advisor and need model portfolios, client reports or custodian integration. That does not exist in Celsmar.
- If you work in English and language is not a criterion. Celsmar's Spanish-interface advantage stops being an advantage.
