Cisco ISR4331 Throughput Licensing

I've searched, but I can't seem to find an answer to this question. For an ISR4331 with the base 100Mbps license, is this 100Mbps per interface (50/50, 70/30, etc), or is this the total amount of traffic that the box will forward? For example, I've got a site with a 20/20 Circuit and a L3 switch hanging off of the 4331. Is that a total of 40Mbps in regards to the license, or is it a total of 80Mbps since the interface facing the switch could potentially be running at 40Mbps also? Put another way, if I have sites that have a 50/50 ISP Circuit, should I be looking at the 300Mbps license, or would the 100Mbps license work for me?
