PASS review
A deep power-analysis tool for research teams planning studies on Windows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PASS is desktop software for calculating sample size and statistical power in research studies. It is designed for clinical trials, pharmaceutical and medical research, academia, business research, quality control, and other work that requires structured study planning. Its coverage extends beyond basic power calculations, with procedures for means, proportions, correlation, survival, regression, ROC analysis, Bayesian approaches, and specialized study designs.
Pricing is organized around single-user licenses. The 1-Year Single-User PASS Subscription License costs $1,195 per user annually and includes the latest or any previous version plus free upgrades. The 2-Year license costs $2,195 per user annually and includes the same version access and free upgrades, along with a multi-year discount. The 3-Year license costs $2,995 per user annually and adds a larger multi-year discount. A Single-User Non-Expiring PASS 2026 License costs $4,995 per user, covers PASS 2026, and does not include free upgrades to future versions. A 30-day free trial is available.
The main strength is analytical breadth: PASS supports more than 1,200 statistical test and confidence-interval scenarios, with regression procedures including linear, multiple, Cox, logistic, and Poisson models. Bayesian adjustment and Bayesian study-design procedures are also included, alongside output tables, plots, power curves, output navigation, integrated documentation, procedure-specific help, and free training videos. Technical support comes from PhD statisticians. PASS fits teams that need extensive study-planning coverage and can work with Windows software. Organizations seeking browser-based access, broader platform support, or a lower-cost entry point should consider an alternative.
