By default, unused CUs do not carry over between monthly allocation periods. Any unused CUs from a monthly allocation will expire at the end of that allocation period.
When CU carry-over is applied:
- The total CU quota becomes cumulative across the subscription term.
- Unused CUs expire when the current subscription term ends and cannot be transferred to a new subscription cycle.
- The standard prepaid discount is reduced by 10%.
- A 12-month prepaid plan with a standard 30% discount will instead receive a 20% discount.
- A 12-month prepaid plan with 50M CUs/month provides 600M CUs available across the full subscription term.
- If 10M CUs remain unused when the 12-month subscription term ends, those CUs will expire and will not carry over to the next subscription cycle.
CU carry-over is only available for prepaid plans with a duration of 3 months or longer. It does not apply to monthly billing or shorter-term subscriptions.
