Output
Usage $ = (2M × $0.15) + (0.5M × $0.6) = $0.60
Labor $ = 0 h × $75.00 = $0.00
Pay-per-use total = $0.60 / mo
Subscription = $20.00 / mo
Difference (subscription − pay-per-use) = $19.40 / mo
Positive difference means subscription costs more than this pay-per-use estimate. This ignores plan-included tokens, support, and compliance work — see receipt "sell @ 10/100" views for that.
