Billing example

The following example shows how fees are calculated for the Basic plan in the Singapore region.

Billing conditions

Cost (USD)

  • Plan: Basic (USD 19/month)

  • Token quota: 6,000,000 tokens

  • Actual usage this month: 7,000,000 tokens

  • Overage: 1,000,000 tokens

  • Pay-as-you-go billing enabled

Cost = Plan fee + Overage fee

= 19 + (1,000,000 / 1,000) × 0.00494

= 19 + 1,000 × 0.00494

= 19 + 4.94

= USD 23.94
