A delivery can look profitable on the ticket and still lose money once the truck leaves the yard. A few extra miles, an unplanned stop, a price change that was not passed through, or a customer account with an old delivery fee can quietly eat the margin. That is why fuel margin analysis needs to be part of the daily operating routine, not something reviewed after the season is over.
For heating oil and propane dealers, the goal is not simply to sell more gallons. It is to know which gallons are producing enough gross profit to cover delivery, labor, equipment, office costs, and a reasonable return. When you can see that clearly, you can fix problems while they are still small.
What Fuel Margin Analysis Actually Measures
Fuel margin analysis compares what you collected for fuel with what that fuel cost your business. At its most basic level, gross margin per gallon is the delivered selling price minus the product cost per gallon.
If you sell heating oil for $3.40 per gallon and the delivered cost of product is $3.00 per gallon, the gross margin is 40 cents per gallon. On a 200-gallon delivery, that is $80 in gross margin before considering the cost of getting that delivery done.
That first number matters, but it is not the full answer. A 40-cent margin on a tightly scheduled 300-gallon route stop is different from 40 cents on a 75-gallon emergency delivery 20 miles out of the way. Both sales may show the same gross margin per gallon, but the second delivery may contribute very little after truck time, driver wages, fuel, card fees, and overhead.
A useful review looks at margin from several angles: cents per gallon, gross margin dollars per delivery, margin by customer class, margin by route, and margin by product. These views help you see whether a problem is tied to pricing, purchasing, delivery operations, or customer terms.
Start With Clean Cost and Price Data
Bad data makes margin reports worse than no reports at all. If rack costs, invoices, taxes, fees, or customer prices are entered late or inconsistently, the result is a margin number that looks precise but is not useful.
First, decide how you will assign product cost. Some dealers use the cost of the load that supplied the delivery. Others use a daily average cost or a weighted average inventory cost. There is no single method that fits every company, but the method needs to be consistent. Changing methods whenever the market moves makes it hard to compare one period with another.
Your selling price also needs to reflect what the customer actually paid. Include agreed contract pricing, fixed-price arrangements, cash discounts, delivery fees, and any service charges that belong with the sale. If a dispatcher changes a price over the phone but the account record is not updated, that difference can disappear into the noise until it becomes a sizable loss.
Propane dealers should pay special attention to gallons sold from bulk plants, cylinder exchanges, and tank fills. Those transactions can carry different handling costs and pricing rules. Heating oil dealers may need separate reporting for automatic deliveries, will-call deliveries, emergency calls, and commercial accounts. Combining everything into one average can hide the work that needs attention.
Gross Margin Is Not Net Profit
A common mistake is treating gross margin as profit. Gross margin is the money left after product cost. It still has to pay for drivers, trucks, insurance, maintenance, dispatch, rent, card processing, bad debt, and office staff.
You do not need to assign every penny of overhead to every ticket to make better decisions. Start with the delivery costs you can reasonably track. For example, compare average gallons per stop, average miles per route, driver hours, and total gross margin dollars for each truck day. A route that consistently has low gallons per stop and too many miles deserves a closer look, even if its posted margin per gallon looks acceptable.
The Numbers That Reveal Margin Problems
Many dealers focus on the posted price and rack price because those are visible every day. The better operating questions go a step further. Are average delivery sizes shrinking? Are small stops increasing? Are discount accounts receiving the same service level as higher-margin accounts? Is one driver or route regularly producing fewer gallons per hour?
Track these measures at least weekly during the busy season:
- Average gross margin per gallon by product and customer type
- Gross margin dollars per delivery and per route day
- Average gallons per stop
- Stops, miles, and gallons delivered per truck hour
- Price overrides, credits, and delivery fees waived
- Accounts that fall below your target margin or minimum delivery size
The point is not to bury the office in reports. It is to find exceptions. If a route normally produces 35 cents per gallon and suddenly drops to 24 cents, review it before the next delivery cycle. Perhaps a commercial account was priced incorrectly, a customer received a discount they were not eligible for, or the route was broken up by too many call-ins.
Watch Margin Dollars, Not Just Cents Per Gallon
Cents per gallon is familiar and useful, but it can lead to poor decisions when used by itself. A 50-cent margin on a 50-gallon delivery creates only $25 in gross margin. A 30-cent margin on a 400-gallon delivery creates $120. If the larger delivery is on an efficient route, it may be the stronger transaction by a wide margin.
This does not mean every account should be judged only by delivery size. Long-term customers, automatic delivery customers, and accounts with service work can have value beyond a single ticket. It does mean that low-volume, high-service accounts need clear pricing and delivery policies. Minimum gallons, small-drop fees, zone-based delivery charges, and scheduled delivery days are practical tools when used consistently.
Use Scheduling to Protect Delivery Margin
A large share of margin loss happens before the driver starts the truck. When deliveries are scheduled manually from paper notes, memory, or disconnected spreadsheets, it is easy to send a truck across town for a small stop while another truck is already in that area.
Automatic delivery scheduling based on degree days or calendar days helps put deliveries on the route before tanks become urgent. That gives dispatch more room to build efficient loads and route density. Call-in orders will always be part of the business, especially during severe weather, but they should not become the default for customers who can be managed on a normal delivery schedule.
Review the accounts that generate repeated short-notice calls. Some may need their estimated usage updated. Others may need a different degree day factor, a smaller delivery interval, or a direct conversation about automatic delivery. The right answer depends on tank size, consumption patterns, credit status, and service expectations. The key is to stop treating recurring delivery exceptions as unavoidable.
A system such as Degree Days Online can help by keeping customer records, delivery history, temperature data, scheduling, tickets, and call-in orders in one operating workflow. When dispatch has current information in front of them, it is easier to make profitable decisions without adding more paperwork.
Turn Findings Into Pricing Decisions
Margin analysis should lead to action, not just a monthly spreadsheet. If an account is consistently below target, first verify the facts. Check the cost basis, delivery size, payment history, tax treatment, and any special price agreement. A report can identify a problem, but it cannot tell you whether the account has a valid reason for different pricing.
Once the numbers are correct, choose the response that fits the relationship. You may adjust the price, add or enforce a small-drop fee, move the customer to a regular delivery day, change the payment terms, or decide the account is strategically worth keeping despite a lower margin. The wrong move is allowing an outdated price or unprofitable service pattern to continue simply because nobody owns the review process.
It also helps to set a target range rather than one rigid margin number. Market volatility, weather, competition, delivery density, and customer mix all matter. A rural propane route may require a different margin expectation than dense residential heating oil deliveries in town. Use your own delivery costs and operating goals to set targets that make sense for your business.
Make the Review Routine
A short weekly margin review is usually more useful than a complicated quarterly project. Look at delivered gallons, average margin, total gross margin dollars, route efficiency, and unusual account activity. Then assign follow-up work while the details are fresh.
The best time to find a pricing leak is before it has affected a full season of deliveries. One corrected account, one tighter route, or one updated delivery policy can improve results without adding a single new customer. Start with the next truck day, ask which deliveries are earning their place on the route, and let the answer guide the work.
