What the AWS Cost Calculator does
An AWS bill is the sum of many services, and it is easy to lose track of which ones drive the cost. This AWS cost calculator lets you enter your monthly spend per category, compute, storage, database, data transfer and everything else, and see the combined total plus which service is your biggest cost driver.
Use it to sanity check a bill, plan a budget, or spot where to focus optimisation. The breakdown chart makes the largest slices obvious, and for a detailed estimate of any single service you can use the dedicated EC2, Lambda, S3, DynamoDB or API Gateway calculators in this section.
Heads up on pricing. The rates built into this tool are public list estimates for July 2026 and can change without notice. Providers also offer batch discounts, prompt caching and volume tiers that lower real costs, so treat the output as a planning estimate, not a quote.
The formula
monthly AWS bill = compute + storage + database + data transfer + other
annual estimate = monthly bill × 12
annual estimate = monthly bill × 12
Worked example
A typical small production setup might be $400 compute, $120 storage, $260 database, $90 data transfer and $80 other, totalling about $950 a month or $11,400 a year, with database and compute as the top two drivers.
Ways to lower your cloud costs
- Right size resources. Pick the smallest instance, memory or capacity that still meets your performance target.
- Commit to steady load. Reserved instances, savings plans and committed use discounts cut rates sharply for predictable workloads.
- Use serverless for spiky traffic. Scale-to-zero services mean you pay nothing while there are no requests.
- Tier cold storage. Move rarely accessed data to cheaper classes such as Glacier, Coldline or Archive.
- Cut data transfer. A CDN and keeping traffic within a single region reduce the egress charges that quietly grow with scale.
Frequently asked questions
How do I estimate my AWS bill?
Add up your spend per service category. This tool sums compute, storage, database, transfer and other into a monthly and annual total and flags your biggest cost.
What is usually the biggest AWS cost?
For most teams it is compute (EC2 or Fargate) or database (RDS). Data transfer egress is a common hidden surprise at scale.
How can I reduce my AWS bill?
Right size and reserve steady compute, move cold data to cheaper storage tiers, use a CDN to cut egress, and delete idle resources. Start with your biggest driver.
Are there free tiers?
Yes, AWS offers free tiers for many services, larger in the first year. This aggregate view assumes your net billed spend after any free allowance.
Are these numbers exact?
This is a planning aggregator using the figures you enter. For service level precision, use the dedicated calculators and confirm rates for your region.
