Whether costs are incurred for inbound traffic, outbound traffic

Question

**I'm using Lightsail $3.50 plan. This plan supports 1TB transfer.**

**Suppose 600GB was used for Inbound traffic(TotalDataXfer-In-Bytes) and 600GB was used for Outbound traffic(TotalDataXfer-Out-Bytes).**

**So, since my total traffic capacity is over 1TB, will I pay extra?**

---

I'm not sure so I'm asking a question. Thanks for your help.

Hello.

Lightsail's data transfer amount includes both inbound and outbound data.  
In your case, you will have to pay for more than 1TB.

> Q: What does data transfer cost?
> 
> Your plan includes a free data transfer allowance. Both data transfer in and data transfer out of your instance count toward your data transfer allowance. For Lightsail content delivery network (CDN) distributions, only data transfer out of your distribution counts toward your allowance.
> 
> If you exceed your data transfer allowance, you will only get charged for data transfer OUT from a Lightsail instance to the Internet or to AWS resources using the public IP address of the instance. Both data transfer IN to Lightsail instances and data transfer OUT from a Lightsail instance when using the instance’s private IP address are free beyond your data transfer allowance. For Lightsail CDN distributions, all data transfer out of your distribution will incur a charge once you exceed your distribution data transfer allowance.

Hello. 
Therefore, you would pay extra for the 200GB of traffic that exceeded the included 1TB.
