Do you have multiple devices that are using your Hughesnet, and if so, what are they? Windows 10 computers can use a ton of data if not set up a certain way. Streaming, of course, can use a lot, too. Facebook automatically playing videos can be another data hog. Do you have anything that might be connecting through your router (if you have one) without you knowing it?
Have you noticed any instances where it seems like the system is using data when you aren't actively using anything?
Glasswire, a free program for your computer, can tell you how much data your computer is using and just what on the computer is using it, but it only monitors the computer, nothing else.
The people on here can help you drill down what is going on.
To add, the following may also help....
The following can help with data usage reduction...
The biggest things with Windows 10 is to turn off syncing, turn off "updates from more than one place," and turn off "OneDrive" and set it so it doesn't start up on computer startup (it's probably on in your system tray). Also go into the settings on Facebook to set it to NOT play videos automatically.
This is also something that may help to do the above things. It's from a previous thread...
If you have Windows 10 on the computers, you will want to make sure that they aren't using the cloud (OneDrive) and aren't syncing. To turn syncing off go to settings, accounts, then "sync your settings." The top option on that page should be to turn your sync settings on or off. Turn it off. As for the cloud (OneDrive), it may be on in your system tray. Right click it and go into the settings and change it so it doesn't start on startup. Then exit out of it to turn it off for that time. Right click it again, click exit and then click "Close OneDrive." It won't start again when your computer starts next time. The last thing with regard to the cloud is to go into settings, system, then storage. Make sure all of the save locations are somewhere on your computer, whether "This PC" or your C drive. Just make sure none of them say anything about the cloud.
Also, go into settings, then Update & Security. Click on Advanced Options, then Choose how updates are delivered. Turn off "updates from more than one place." That's another thing that will eat up some bandwidth.
Then make sure Facebook isn't set to play videos automatically.
Those few things alone will probably save you a lot of bandwidth.
Here's the link for Glasswire, by the way... https://www.glasswire.com/
Also, one other good idea would be to install an ad blocker. Those ads on just about all websites can use quite a bit of data, as well. The most popular one seems to be AdBlock Plus. You can get that at... https://adblockplus.org/ It's free, as well, and there are versions for just about any browser you are using.
