If it matters I am especially interested in price based on rate of usage, as with electricity. Could be there's no exact term, in which case my most profound apologies
The kilowatt-hour (symbolized kWh) is a unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour. Inversely, one watt is equal to 1 J/s. One kilowatt-hour is 3.6 megajoules, which is the amount of energy converted if work is done at an average rate of one thousand watts for one hour.
We live in Sunnyvale, CA, USA. Our rates change based on usage from PG&E; higher rates for higher usage.

*System-wide average consumption is about 500 kWh per month. Typical bills are for customers in inland coasta
Thanks Cis but I'm not interested in actual rates, I'm simply looking for a word--probably an adjective--that differentiates a rate that decreases with usage with one that increases. As you point out our electricity qualifies in the latter category
That's be a pretty acceptable choice to my ear. However, to my knowledge, there's s no one-word description. As much as Dale seems to want there to be a one-word phrase, there's none to be had.
