What describes the RI total reserved cost break-even point?

• A. The moment when the on-demand cost of resource usage is greater than the total cost of the commitment.
• B. The date when the upfront payment has been fully recovered.
• C. The point where on-demand costs are higher than the total cost of the commitment, but you could stop using the reservation and not lose money; after this you start realizing savings.
• D. The time when the reservation term ends.

Answer: (C)

The key idea is the break-even point for a reserved instance: you compare the total cost of the reservation (upfront and any ongoing terms) to the on‑demand spend you would incur for the same usage. The break-even occurs when the on‑demand costs you would have paid without the reservation become higher than the total cost of the reservation. From that moment onward, continuing to use the reserved capacity yields real savings, since the savings from the discounted on‑demand rate exceed the reservation’s cost. In practice, this describes the moment when you are past the threshold where the reservation pays for itself and you start to realize savings, assuming you keep using the reserved resources.
