AWS credits automatically apply to your monthly bill for eligible services including EC2, S3, RDS, Lambda, and SageMaker. You do not need to manually redeem them — they offset charges as you use AWS services.
AWS credits work as automatic bill offsets — you do not need to do anything special to use them once they are in your account. When you use AWS services, your credit balance automatically covers the charges before any credit card payment is processed. This makes them extremely convenient compared to voucher-based discount systems.
To check your credit balance, log into the AWS Management Console and navigate to Billing and Cost Management. Under "Credits," you will see your available credit balance, the expiry date for each credit, and which services they can be applied to. Most credits from promotional programs or purchased accounts apply to all standard AWS services including EC2, S3, RDS, ElastiCache, CloudFront, Lambda, API Gateway, SageMaker, EKS, and many others.
Some credits have service restrictions. For example, certain credits may not apply to marketplace purchases, support plans, or Reserved Instance upfront payments. Always check the credit terms in your Billing dashboard to understand any restrictions on your specific credit balance.
To maximize the value of your AWS credits, plan your workloads carefully. EC2 is typically the largest cost driver for compute-heavy applications — consider using spot instances or Savings Plans to stretch your credits further. S3 storage and data transfer costs can accumulate quickly if you are storing or serving large amounts of data. Using CloudFront as a CDN in front of S3 can reduce data transfer costs and make your credits last longer.
For machine learning workloads, SageMaker training jobs and inference endpoints can consume credits quickly if you are using large GPU instances. Start with smaller instance types to validate your models before scaling up to p3 or p4 GPU instances. For containerized workloads, EKS with Fargate allows serverless compute that bills only for actual resource consumption, which can be more credit-efficient than always-on EC2 instances.
Setting up AWS Cost Explorer and billing alerts is strongly recommended when using credit accounts. This allows you to track your spending rate and project when your credits will be exhausted. With proper monitoring, you can optimize your usage and ensure your credits last as long as possible for your workloads.
