AWS Scaling Cost Explosion Simulator
What happens to your AWS bill if you go viral? See the cost at 2x, 5x, and 10x traffic to understand the true cost of growth.
What's your current AWS spend?
We'll use this to project costs at different growth scenarios.
Tip: Use your AWS Billing Dashboard to find last month's total across all services.

Who This Tool Is For
Founders, startup CTOs, and product leaders building on AWS who fear that viral growth will result in an AWS bill they can't afford. If you're thinking about fundraising, Series A, or planning for product-market fit, understanding your cost trajectory at scale is critical.
Why We Built This Tool
Startups often get blindsided by infrastructure costs at scale. They assume costs scale linearly with traffic, but real AWS costs scale non-linearly depending on your architecture. Lambda doesn't scale the same way as EC2. RDS doesn't scale the same way as DynamoDB. This tool makes that visible before growth surprises you.
What Problem It Solves
- Silent cost bombs. Most startups don't model AWS costs at 10x scale until it's too late.
- Architecture decisions locked in. The wrong choice (EC2 vs Lambda) at the start gets expensive fast. This shows you the cost difference.
- Investor conversations. When fundraising, having a credible cost model builds confidence with technical investors.
- Lack of cost ownership. Engineers don't know how expensive their scaling will be. This makes it concrete.

How to Use This Tool
- Enter your current monthly AWS spend. Find this in your AWS Billing Dashboard.
- Tell us which services you're using. EC2, Lambda, RDS, etc. This affects scaling behavior.
- Choose your scaling model. Auto-scaling/serverless, or fixed provisioning?
- See the cost scenarios. We show you what your bill could be at 2x, 5x, and 10x traffic.
Frequently Asked Questions
How do you calculate scaling factors?
We use real-world AWS service scaling characteristics: EC2 scales 1:1 with traffic (linear), Lambda scales ~0.7x (sub-linear because of efficiency), and RDS scales ~1.2x (super-linear due to connection pools and query complexity). Your actual scaling depends on workload characteristics, but these are solid benchmarks.
Doesn't this assume static architecture?
Yes. Real optimization happens when you re-architect for scale (e.g., move from EC2 to Lambda, or RDS to DynamoDB). This tool shows the cost if you scale your current architecture linearly. Our team can help you design a cost-optimized architecture for growth.
What if my AWS usage is unpredictable?
Use the auto-scaling estimate. Serverless (Lambda, Fargate) has sub-linear cost growth because infrastructure handles variability for you. Fixed EC2 assumes you provision upfront and pay whether you use it or not.
