AWS helps you reduce your overall IT costs in multiple ways. With AWS you can replace your upfront capital expense with low variable cost and pay only for the resources you consume. AWS's economies of scale, and efficiency improvements, allow AWS to continually lower prices, while multiple pricing models allow you to optimize your costs for both variable and stable workloads.
AWS is more cost-effective than on-premises environments in both the short, and long, term. To help validate these savings, AWS commissioned IDC to interview 11 organizations that deployed applications on AWS. IDC discovered that the five-year total cost of ownership (TCO) of developing, deploying, and managing critical applications in AWS delivered a 72% savings when compared with deploying the same resources on-premises, or in a hosted environment. The report also found a 626% ROI over five years.
AWS offers a simple, consistent, and transparent pay as you go pricing model, charging you only for the resources you actually consume. Moreover, with AWS there are no upfront fees, no minimum commitment, and no long-term contracts required.

For storage and data transfer, AWS follows a tiered pricing model. The more storage and data transfer you use, the less you pay per gigabyte. In addition, volume discounts and custom pricing are available to customers for high volume projects with unique requirements.
AWS Tiered Storage Pricing
For certain AWS services like EC2 and RDS, you can invest in reserved capacity. In these cases, you pay a low upfront fee and get a significantly discounted hourly rate. A Reserve Instance purchase can results in overall savings of up to 60% (depending on the type of instance you reserve and your utilization) over equivalent On-Demand capacity. Save even more (up to 99%) compared to pro-rated AWS pricing by purchasing RIs listed by 3rd Party sellers in the RI Marketplace.
