If you currently have 100 customers on 20Mbps via a single PoI, then at a contention ratio of 20:1 that means you need ~100Mbps of connectivity. Add in a single 1Gbps connection to the mix, and you need to upgrade that 100Mbps to at least 1Gbps - a 10 fold increase in speed, and a 10 fold increase in cost. Of course, if you already have hundreds or thousands of customers with 100Mbps on a single PoI, then you're correct - the required increase in bandwidth would be much smaller.
