Yeah, the short answer is that the math is really not that simple. Going back to prior comments, fuel is just one of many elements that get negotiated as part of a customer's rate each year. So, it could be that we get more fuel surcharge in one particular more, more base rate in another. And so, trying to look out and measure what the surcharge revenue piece is versus what the potential expense might be is not really a one-for-one comparison in that regard. The surcharge, if a customer has decided to take on more variable exposure to that fluctuation in fuel is covering many more cost elements than just the cost of fuel and other petroleum-based products.
Certainly that's what it's designed to cover, but that's not everything that is covered by that variable component of pricing. So, again, I think the -- if you want to look back into a declining fuel environment, I would point people to look at 2015, and 2016. In '15, the average price of fuel was down 30% that year. Of course, we had volume growth, it was a little different macro environment, and so as a result we were able to improve the operating ratio that year. In '16, the average price of fuel decreased further. It decreased about 15% that year, and that was one of the years, as I mentioned earlier, that we had a 60 basis point increase in the operating ratio.
That the overall macro was a little softer, volumes were certainly flattish that year. And so, a little bit different top line makeup, if you will. But so, that's probably a little bit more relative comparison, is looking back at how some of those revenue changes quarter-to-quarter, and cost changes progressed in that year. But we're certainly managing through it. And we're looking at -- we've got contracts that turn over every day, and they progress through the year. So, if fuel stays where it is today, then we're looking at a contract with a base rate of a fuel at $4.58 a gallon versus, last year, we were looking at it and it would have been $5-something per gallon.
So, you just always got to look at what the current environment looks like, and then try to risk-adjust for do you think fuel prices may go up? If they do, again, how does the top line for each individual customer account change, and what do the cost inputs change? If fuel goes down, you do the same thing, and you try to make sure that those fuel scales, as they work on each customer account, that we're still effectively getting paid for the service that we're providing and, like Greg said, the value that we are offering. And so that's what we stay focused on. And it's less important for us to look at the profitability of each customer account.
