Developers, students, and startups using AWS free tier for development and learning. If you're on the free tier and wondering when it ends, this tool gives you a clear timeline and first bill estimate.
Why We Built This Tool
AWS free tier surprise bills are a rite of passage. Most developers don't realize how quickly free tier limits can be hit, especially for services like data transfer. This tool makes it transparent so you can plan ahead.
What Problem It Solves
- Surprise bills. Developers get shocked by their first AWS bill. This prevents that.
- Unclear limits. AWS free tier limits are complex and scattered. This centralizes them.
- No timeline visibility. When exactly will I hit the limit? This tells you.
- Cost planning for growth. Understanding when free tier ends helps you budget for scaling.

S3
5 GB storage, 20,000 GET, 2,000 PUT requests per month.
RDS (db.t2.micro)
750 hours + 20 GB storage per month.
Data Transfer

Frequently Asked Questions
How long does free tier last?
12 months from account creation for most compute services. Some services (Lambda, S3) offer free tier indefinitely, but with monthly limits.
What if my usage is variable?
Use your average or peak day. If you're inconsistent, use the higher number to be safe. This tool shows you the worst-case scenario.
Can I extend free tier?
Some services offer extended free tier (Lambda forever, S3 for life). For EC2/RDS, the 12-month window is fixed. Budget for paid tier costs after free tier expires.
How can I reduce my bill?
Use auto-scaling (only pay for what you use), schedule resources (stop instances at night), use managed services (serverless), and enable Savings Plans early.
