About this calculator
How is the recoverable AI spend calculated?
+
Idle seats are paid seats minus active seats, times seat price, times 12. Overlapping tools are active users with a second, duplicate assistant, times seat price, times 12. Model right-sizing is annual API spend, times the share on oversized models, times the saving from using the right model.
Where do I find my real seat utilization?
+
Admin consoles show some of it per vendor. PromptGlass combines connector data and sensor activity across every AI tool to measure it consistently, which is what the free assessment delivers.
Is this calculator a quote or a guarantee?
+
No. It is arithmetic on the numbers you enter. Your results depend on your actual usage, contracts and the actions you take.
