Amortized cost
Cost with any upfront commitment payment spread evenly over the hours or days it covers, instead of counted on the day it was paid. It gives each covered resource a realistic daily cost. In ZopNight, Azure billing data is amortized; AWS and GCP billing data are not amortized by default. Why it matters: Without amortization, a large upfront purchase looks like a one-day spike and covered resources look free.
