A visible method
The assumptions stay in the room.
Compare the load
Low, typical, and high usage use the same included amount and overage price you enter.
Inspect the carry
The next-cycle columns show capped carry, consumption, expiry loss, and a repeat-scenario comparison.

FAQ
The scope stays explicit.
What does this tool compare?
It compares three usage scenarios for one user-defined week or calendar month, including overage, unused included units, and an optional user-assumed rollover.
Does the unit label have a standard meaning?
No. Enter hours, tickets, deliverables, response windows, or another unit you can describe consistently. The label is shown as entered and is not interpreted.
Are values saved or placed in a link?
No. This review tool calculates locally and has no share state, URL parameters, storage, account, or analytics event.
What does rollover mean here?
Rollover is only the carry assumption you enter. The expiry date and next-cycle comparison are arithmetic scenarios, not a platform balance.
