Calculating router throughput

I'm working on finding routers to replace two 2921 core router pairs at my work. I'm looking at 4331s which can provide aggregate throughput of 100-300Mb or higher depending on licensing.

What I'm trying to do is calculate our current average aggregate throughput based on NMS data and I want to make sure I'm going about this correctly.

Each of our routers has 5 interfaces and there are 2 HSRP pairs so only one of each pair handles the vast majority of the traffic.

Do I simply take the average in bandwidth and out bandwidth of each interface and add them all up?
