Primavera P6 is the contract-grade CPM standard — when a DOT or owner mandates a scheduling tool, it's usually this one. Ganttry doesn't pretend to replace that mandate. It opens the XER files P6 users send, logic and calendars intact, and gives the rest of the team one live project in the browser at $20/user/month instead of a Windows desktop license that costs $4,733.60 in year one at Oracle's own store price ($3,880 perpetual + $853.60 first-year support), or roughly $4,300 from resellers, as of September 2026.
Ganttry's annual plan vs a P6 Professional perpetual license plus first-year support, as of September 2026: Oracle's own store lists $3,880 plus $853.60 for first-year support ($4,733.60), and resellers sell the pair for about $4,300. That's more than a 20× difference either way, not a promise of your own savings.
Work on one shared project. See who is there, review save conflicts, and open saved revisions. P6 Professional is a Windows desktop app: single-user on its own, shared only through an Oracle or SQL Server database — otherwise schedules travel as XER files.
Ganttry imports XER with logic and calendars preserved, and re-imports monthly updates in place. It does not export XER — if the contract requires P6-native files, you still keep a P6 license.
Oracle sells P6 Professional in its US online store at $3,880 per user, perpetual, plus $853.60 for first-year support; its downloadable price lists carry no P6 line. Resellers sell it for less in their own web stores. The figures below are Oracle's store price and what resellers publish, as of September 2026.
Oracle's online store lists $3,880 per application user, perpetual; reseller store prices land around $3,492–3,500. You can buy from Oracle's store, Oracle sales or a reseller.
Oracle support is priced at about 22% of the list license ($853.60 the first year at Oracle's store; one reseller sells it for $700), so year one is $4,733.60 at Oracle's store price, or ≈$4,300 at reseller prices. Support is billed annually in advance. It's optional, but it's what gets you updates and support, and lapsed support costs a reinstatement fee to bring back.
Oracle's newer cloud scheduler, also sold through resellers. A different product from P6 Professional — this page compares against the desktop P6 most contractors are actually asked for.
Compared against P6 Professional, the desktop edition. On core CPM mechanics the two agree — the split is collaboration, access and price on one side, enterprise depth on the other.
A perpetual license sounds cheaper eventually — but with ~22% annual support renewing on top of a ≈$3,880 license, P6 never crosses under Ganttry's line. Five years out, one supported P6 license (≈$7,500 at today's support price) still costs about what thirty-five years of Ganttry would. And that's for one person: P6 pricing is why only the scheduler gets P6, while Ganttry's $20 is why the whole crew gets Ganttry.
P6 figures are reseller prices (≈$4,300 year one, ≈$800/yr support renewals thereafter at today's price). They are estimates, below Oracle's own store price of $3,880 per user (perpetual) plus $853.60 first-year support, which is $4,733.60 in year one. Ganttry is the published $200/user/yr annual plan.
Drop the XER your scheduler or GC sends into Ganttry and the logic, lags and calendars come through intact. Monthly updates re-import in place. To be plain about the reverse trip: Ganttry exports PDF, Excel, CSV and MS Project XML — not XER. If the owner mandates P6-native files, keep one P6 license for the submittal; Ganttry is where the rest of the team works between submittals.
