SQL Server License Savings Calculator

Put your SQL Server licensing numbers in — get an honest 3-year savings range for moving to PostgreSQL, with the assumptions stated up front.

Your SQL Server estate

Total cores licensed across the estate (4-core minimum per instance).

Your EA renewal / SA figure if you know it. Leave blank to estimate from list-price equivalents.

Your estimate

Enter your estate details and run the calculation.

How we estimate. List-price equivalents as of September 2026: Standard ≈ $465/core/yr, Enterprise ≈ $1,719/core/yr (derived from ~$3,717 and ~$13,748 per 2-core pack with ~25%/yr Software Assurance — verify current list prices on Microsoft's SQL Server pricing page; Enterprise Agreements change these materially). PostgreSQL infrastructure is modeled at 20–45% of current annual license spend. One-time migration effort is modeled at 0.5–1.5× annual license spend by complexity. Ranges are directional — your EA discounts, workload profile, and T-SQL complexity move the real number.

Estimate, not a quote. These figures are directional estimates from public pricing and stated assumptions — not a bid, not a quote, and not a substitute for your EA terms or a formal assessment. Actual savings depend on your workload complexity, license position, and migration scope.
