Billing rules

⇅Inbound + outbound both use the allowance
↑Overage is charged on outbound only; inbound is always free
=Only same-region, same-size instances pool; dual-stack and IPv6-only of one size pool together
hBilled hourly; stopped instances still bill, only deletion stops it
✕Overage already incurred cannot be offset by new instances; scale up before you run out
↺Deleting and recreating does not reset this month’s usage
⇄Traffic over private IPs in one region uses allowance but is never charged
≈Estimates use 1 TB = 1024 GB and UTC calendar months; your AWS bill is final
