FAQ
What does this tool tell you?
The Cloud Spend Estimator computes monthly compute cost across AWS, GCP, and DigitalOcean with reserved instance discount modeling.
What affects the result most?
AWS vs DigitalOcean: EC2 t3.medium $30/mo vs Droplet 2vCPU/4GB $18/mo — 40% savings common. Reserved instances: 1yr no-upfront saves ~30% vs on-demand, 3yr saves ~50%. Data transfer: AWS charges $0.09/GB egress, DigitalOcean includes 1-5TB/mo free.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
