On July 27, the Department of Energy’s weekly on-highway diesel average landed at $5.313 a gallon — up 17.9 cents in a single week and up $1.508 from the same week last year, according to the EIA’s weekly survey. Run that through a truck averaging 6.5 miles per gallon and the year-over-year move alone is about 23 cents per mile of new cost. On a truck turning 100,000 miles a year, that is roughly $23,000 — per truck — that appeared in twelve months and asked nobody’s permission.
Here is the question that decides whether that $23,000 comes out of your pocket or your shipper’s: when you quoted your direct freight, did you quote an all-in rate, or a linehaul rate with a fuel surcharge schedule attached? Every large carrier your shipper works with invoices with a surcharge schedule. Most small carriers quote all-in — one number, fuel buried inside it — because it feels simpler and because nobody ever taught them to build the schedule. Then diesel moves a dollar and the all-in carrier eats the whole move, politely, invoice after invoice.
Today’s lesson fixes that. The Peg-Base-Band system is the way ILG teaches small carriers to build a fuel surcharge schedule a direct shipper will actually sign: three decisions, one page, ten minutes a week to run. It pairs with the Floor-Target-Walk pricing method — that lesson built your linehaul number; this one protects it.
The $23,000 Problem Hiding in Your All-In Rate
An all-in rate is a bet on the price of diesel, and you are the one holding the bet. Quote a shipper $2.60 a mile all-in in March with diesel at $3.80, and you priced roughly 58 cents a mile of fuel into that number. By late July, with the national average at $5.313, the same fuel costs you about 82 cents a mile. Your linehaul — the money that pays the truck note, the insurance, the driver, and you — just quietly shrank by 24 cents a mile, and your shipper never saw a rate change, because the erosion happened inside your number. We covered what July’s fuel spike is doing to per-mile costs when the average first crossed $5; it has climbed another 30 cents since.
A fuel surcharge schedule takes the bet off the table entirely. It splits your rate into two parts: a linehaul that never moves without a negotiation, and a fuel line that floats mechanically with a published government index. When diesel rises, your invoice rises by formula. When diesel falls, the shipper’s cost falls the same way — and that symmetry is exactly why shippers accept it. You are not asking for more money. You are asking for the same arrangement every asset carrier in their routing guide already has.
The Peg-Base-Band System: Three Decisions, One Page
Every fuel surcharge schedule ever written comes down to three decisions. The Peg: which published diesel index the schedule follows. The Base: the fuel price already built into your linehaul rate — the point where the surcharge equals zero. The Band: how the schedule converts each step in diesel price into cents per mile on the invoice. Make those three decisions deliberately and you have a schedule you can defend in any shipper meeting. Let a broker or a shipper make them for you and you will discover, usually in a quarter like this one, that each decision was made against you.
Decision One: Pick Your Peg
The peg is non-negotiable territory: it must be published, free, and beyond either party’s influence. The industry standard is the DOE/EIA weekly on-highway diesel average, released every Monday afternoon. Nobody argues with it because nobody controls it. But choose the geography deliberately. The EIA publishes a national average and regional averages, and the spread between them right now is enormous: California is at $6.670 while the Gulf Coast sits at $5.087 — a $1.58 gap. A carrier running California lanes on a national-average schedule under-recovers by roughly 21 cents per mile at 6.5 mpg. If 80 percent of your fuel is bought in one region, peg to that region’s index. If your lanes wander, the national average is the honest choice — and the easiest to sell.
Decision Two: Set Your Base
The base is the diesel price at which your surcharge reads zero — the fuel cost you already priced into your linehaul. This is the decision shippers and brokers most often rig: a schedule with a base of $4.50 in a $5.31 market has already handed the counterparty a dollar a gallon of your fuel cost before the first load moves. Set your base where your linehaul math actually lives. If you built your rate when diesel was $3.50, your base is $3.50. If you are quoting fresh business this month, you can set the base near today’s price and quote a slimmer linehaul — the total lands in the same place, but from then on fuel risk belongs to the index, not to you. The one thing you may not do is leave the base unstated. An all-in rate is just a surcharge schedule with a secret base, and the secret always costs the carrier.
Decision Three: Build the Bands
The band converts diesel price into cents per mile, and the formula is one line: surcharge per mile equals the index price minus your base, divided by your fleet’s real fuel economy. Use your actual number from your ELD or fuel receipts — not the 7.2 mpg your spec sheet claims. At a base of $3.50 and a true 6.5 mpg, the arithmetic goes like this: build brackets 25 cents wide, and each bracket adds 25 cents divided by 6.5 — call it 4 cents per mile. The bracket containing today’s $5.313 average runs $5.25 to $5.499; take the midpoint of $5.37, subtract the $3.50 base, divide by 6.5, and the schedule reads 29 cents per mile. On a 480-mile lane that is a $139.20 fuel line on the invoice — computed, not negotiated. Write the table from $3.50 up to $7.00 so nobody has to amend it when the market does something ugly, and put the formula at the top of the page so the shipper can audit any row in ten seconds.
One warning: some shippers will offer a percent-of-linehaul surcharge instead, because it is what their TMS defaults to. Decline it. A percentage schedule ties your fuel recovery to your rate, so when rates soften your fuel money shrinks even if diesel does not move — you get hurt on both ends of the same cycle. Cents per mile, pegged to a public index, with a stated base. That is the whole church.
The Script That Sells It
The schedule is math; getting it signed is a conversation. Have it when you quote new business, or at your next rate review with an existing shipper — never mid-week on the phone about one hot load. Here is the presentation, close to verbatim:
The most common pushback is some version of “our other carriers just quote all-in.” Do not argue — reprice the risk out loud:
Running the Schedule Without Drama
A schedule only builds trust if you administer it like a bank. The EIA posts the new average every Monday afternoon; your schedule takes effect Tuesday morning and holds through the following Monday. Put the reference on every invoice — one line: “Fuel surcharge per attached schedule; DOE avg 7/27: $5.313; $0.29/mi.” When the bracket changes, send the same two-sentence note every time, in both directions. The weeks you announce a decrease are the weeks that buy you years of credibility — and they cost you nothing, because the decrease was never your money. Get the schedule referenced in your rate confirmation or carrier-shipper agreement alongside your payment terms; if you followed the Four-C credit system, it lives in the same one-page terms document your shipper already signed.
This Week’s Assignment
Build your schedule and present it once. Monday: pull your true fleet mpg from your ELD and the current DOE average from the EIA page, pick your peg and your base, and build the bracket table from $3.50 to $7.00 in a spreadsheet — it is one formula dragged down forty rows. Tuesday: pick your one direct shipper with the most miles on an all-in rate. By Friday: sit down with them, run the presentation script, and leave the one-page schedule behind. One shipper, one page, one conversation. If diesel does at the end of this year what it did in the last twelve months, this is the highest-paid hour you will work all quarter.
Bottom Line
Diesel at $5.31 is not the problem — diesel you priced at $3.80 and are still hauling at $3.80 is the problem. The Peg-Base-Band system turns fuel from a bet you keep losing into a line item that runs itself: a public index nobody can argue with, a stated base nobody can hide, and a bracket table anybody can audit. Your linehaul is your business; fuel is just weather. Build the schedule this week, sell it with the script, administer it like a bank — and the next time the market moves a dollar a gallon, in either direction, it will be the least interesting thing that happens to your company all summer.
Questions Carriers Ask
How does a fuel surcharge schedule actually work?
You peg your surcharge to a public diesel index, set a base fuel price that’s built into your line-haul rate, and define bands: for every set increase in the index above the base, the surcharge steps up a set amount per mile. Published weekly index numbers make it automatic and arguable-proof. The shipper can verify every adjustment against the same public number you use.
Can I add a fuel surcharge to a shipper I’ve been hauling for at a flat rate?
Yes, but frame it as protecting both sides rather than a rate increase. A surcharge floats down when fuel drops, which flat rates never do, and that’s your selling point. Bring the schedule in writing, tie it to the public index, and propose it at your next rate conversation rather than mid-load.
What happens if I keep running flat rates while diesel keeps climbing?
Every fuel spike comes straight out of your margin, and on thin small-carrier margins a sustained jump can turn profitable lanes into losers without a single rate changing on paper. Carriers with surcharge schedules pass the spike through, so you’re effectively subsidizing your shipper. Getting a peg and band structure in place before the next spike is much easier than negotiating during one.
