Measuring Internet Bandwidth
I need to sign a new contract with our ISP and they wanted to know if we want to stay at 16mb or go up to 25mb. I don't really know how much we are using right now so I was wondering if there are any free tools that I can use to monitor our bandwidth coming in.
I believe that manage engine also has a netflow analyzer that is free for 2 interfaces being monitored.
Also, you can use dd-wrt for a basic router to track bandwidth usage.

If you can put up a port mirror for the internet router's LAN port you can run Wireshark and look at the summary in statistics to get a feel for what you are using in any given period of time.
If not you can take a couple of snapshots of the port counters for a known period of time and then do the math to calculate the bandwidth.

Hello,
You can use PRTG - http://www.paessler.com/prtg
It is free up to 20 sensors. So if you use it only for one router, it is more then enough.
It is simple to set up and manage. All you need to do is setup snmp community on your router and add router and interface of interest into PRTG.
Regards!

Adding my 2 cents: Please check if your ISP is counting uploaded and downloaded bytes towards your bandwidth.
If you have a managed switch, the information may be easy to get. There are some not-so-fun alternatives:
1. If you are using Windows computers, write a WMI script to read interface statistics of all computers connected to your LAN
2. Enable SNMP and read interface statistics
3. Do it on a busy day (lots of data and updates) and multiply that with 30.
