Imagine slashing your AWS bills while maintaining access to top-tier cloud resources. It might sound too good to be true, but AWS Savings Plans make it possible. Let’s explore how these plans work and how they can optimize your cloud costs.
What are AWS Savings Plans?
AWS Savings Plans are a flexible pricing model that provides substantial cost savings for cloud computing usage. By committing to a consistent dollar amount per hour over a one- or three-year term, customers benefit from lower prices on compute capacity compared to on-demand instances. These plans are designed to optimize AWS compute usage, offering discounts of up to 66-72% depending on the selected plan and commitment level.
Unlike traditionally reserved instances, Savings Plans automatically and simultaneously apply to eligible AWS compute usage, including EC2 instances, AWS Fargate, and AWS Lambda. This enables businesses to centralize and simplify cost management while benefiting from significant cost savings.

How AWS Savings Plans work
Savings Plans operate on a commitment-based model. You agree to spend a fixed dollar amount per hour. AWS then applies discounted rates to your usage within the committed threshold. Usage exceeding this threshold is billed at standard on-demand rates.
Payment Options:
- No Upfront Payment: Commitments are charged monthly, providing flexibility.
- Partial Upfront Payment: Offers lower prices for predictable workloads.
- All Upfront Payment: Provides the most significant cost savings for stable, predictable workloads
Types of AWS Savings Plans
Along with different payment options, there are three different types of savings plans that customers can choose from, depending on their goals and workload requirements:
1. Compute Savings Plans
- Key Features: These plans apply to any EC2 instance, regardless of instance family, region, operating system, or tenancy.
- Ideal For: Businesses with dynamic, scalable workloads that may migrate across families or areas.
- Savings: Up to 66% compared to on-demand rates.
2. EC2 Instance Savings Plans
- Key Features: These plans are specific to instance families and regions and offer a higher discount for predictable workloads.
- Ideal For: Organizations with steady-state usage confined to particular configurations.
- Savings: Up to 72% cost reduction.
3. Amazon SageMaker Savings Plans
- Key Features: Designed for machine learning workloads, these plans optimize costs for consistently using Amazon SageMaker instances.
- Savings: Up to 64% compared to on-demand.

How to get started with AWS Savings Plans
Getting started with AWS Savings Plans is easy. You can access and purchase them through the AWS Cost Management Console. The console generates recommendations for savings plans based on your usage and cost data to save you the most money. You can specify parameters, including type, term, and payment options.
To get started:
- Review Savings Plans Recommendations: The AWS Cost Explorer generates personalized recommendations based on your current usage and costs.
Metrics to Monitor:- Monthly On-Demand Spend: Helps determine your optimal commitment level.
- Estimated Monthly Spend: Project costs under a Savings Plan.
- Estimated Monthly Savings: Displays potential savings based on recommendations.
- Analyze Workloads and Resource Needs: Assess your current compute usage, instance family, region, and operating system requirements.
- Commit to a Plan: Choose a plan type, term, and payment option that aligns with your business goals.
- Monitor and Adjust: Use tools like AWS Cost Explorer Savings Plans reports to ensure your commitments align with your evolving usage.
What reports does Amazon provide to help manage savings plans?
Amazon provides several reports to help you manage your savings plans and track your cost savings:
- Utilization Report: This report shows the percentage of your savings plan commitment you are using. It also provides valuable metrics such as On-Demand Spend Equivalent, Savings Plans spend, and Total Net Savings.
- Coverage Report: This report shows how much of your eligible spending was covered by existing savings plans. It also highlights any potential savings you could achieve by increasing your commitment.
These reports can help you gain valuable insights into your savings plan usage and make informed decisions to optimize your cost management.
What is the difference between a savings plan and a reserved instance?
Savings Plans and Reserved Instances are potent tools in your cloud cost optimization arsenal, offering significant discounts compared to on-demand pricing. However, they differ in several key aspects that can influence your decision on which option is best suited for your needs.
Cost Savings: While both offer substantial discounts, Reserved Instances generally provide a slightly higher discount, reaching up to 72% compared to Savings Plans, which offer up to 66%. While seemingly small, this difference can translate to significant savings over time, especially for large-scale deployments.
Flexibility: Savings Plans are the champions of flexibility. They can be applied to any EC2 instance, regardless of instance family, region, operating system, or tenancy. This makes them ideal for dynamic workloads that might change over time or require migration between different instance types or areas. On the other hand, Reserved Instances are less flexible, as they are locked to a specific instance family and region. This makes them a better fit for stable, predictable workloads that are unlikely to change significantly.
Liquidity: Reserved Instances offer a degree of liquidity that Savings Plans lack. If your needs change and you no longer require your Reserved Instances, you can sell them on the AWS Marketplace, recouping some of your investment. Savings Plans, however, cannot be sold or transferred, making them a less liquid asset.
Best Practices for AWS Savings Plans
To maximize the benefits of Savings Plans, follow these best practices:
- Analyze Usage Patterns: Use AWS Cost Explorer to understand historical usage and steady-state demands.
- Choose Longer Terms: Opt for three-year commitments for more significant cost savings when workloads are predictable.
- Leverage Compute Savings Plans: These plans provide unmatched flexibility for dynamic workloads.
- Review Regularly: Periodically evaluate your Savings Plan utilization to align with evolving business needs.
- Use Management Tools: Simplify cost management with AWS tools to track and adjust your commitments.
AWS Savings Plans are a foundational tool for cloud cost optimization. Consistent computing can boost significant cost savings, reduce your computing bill, and simplify cost management. Whether you choose Compute Savings Plans for flexibility or EC2 Instance Savings Plans for predictable workloads, these plans enable businesses to achieve cost-effective and scalable cloud solutions.
