You are overlooking TCP/IP protocol bytes which add between 5 and 13% to the data and are considered billable traffic by providers. At 18M it's solidly over 100TB, at 16.5M it will consume 97TB in 31 days.
Another consumer of bandwidth is name resolution, if this is an exit node. And the traffic incurred by the resolutions is not reflected in the relay statistics.
An exit node that allocates 100% of it's bandwidth to relaying traffic will starve the resolver, and vice versa.
