Annualized Ownership Cost
The modeled per-year cost of owning a system over a defined hold period: amortized hardware, maintenance, and software licensing combined.
This site models annualized ownership cost over a 5-year hold, using IBM's published ~15% of hardware price as the hardware maintenance baseline, plus the applicable IBM i tier's software cost. See Annualized Ownership Cost for the full generation-by-generation model and its assumptions.

Cost per Useful Year
Annualized ownership cost divided by remaining useful life -- what a generation actually costs per year of IBM-supported service you get out of it, not just its sticker price.
