I have a 150 megabits/sec Comcast pipe that connects to two subnets through two Cisco routers. The bandwidth at the modem is 150 Mb/s. The bandwidth at one router is 96 Mb/s and the other is 96 Mb/s Neither has the full 150 Mb/s. Does the bandwidth divide into two values, or are the routers causing the reduction in bandwidth?

    Welcome to NE, we hope you find this a great community to contribute to and learn from. You could improve your question by editing it to add more details. You may find our Network Engineering Question Checklist helpful when editing your question. For example: What are the Cisco router models? 96 Mbps sounds a lot like they only only have 100 Mbps ports.

You have some limitation in your network to 100mb/s as @YLearn said. It is either on the machine interface you are testing, router port or somewhere else.

A Thumb Rule: A chain is only as strong as its weakest link.
