Formula
Determines what percentage of your rates should increase based on fuel price change and how much of your cost structure is fuel.
Worked Example
How Courier Fuel Surcharges Are Calculated
- If fuel rises 28.6% (from $1.40 to $1.80) and fuel is 30% of costs, the surcharge is about 8.57%
- On a $10 base delivery rate, an 8.57% surcharge adds $0.86 per package
- Ground couriers typically have fuel as 25-35% of operating costs
- Major carriers like FedEx and UPS update surcharges weekly using published diesel indices
- Surcharges are transparent line items, making them easier for customers to accept than base rate hikes
A well-calculated fuel surcharge protects courier margins during volatile fuel markets while keeping base rates competitive and predictable for customers.

Frequently Asked Questions
What is a fuel surcharge?
An extra charge added to shipping and delivery rates to account for fluctuating fuel prices. It keeps base rates stable while passing fuel cost volatility to customers as a transparent line item.
What percentage of costs is fuel for couriers?
For ground couriers, fuel is typically 25-35% of total operating costs. For air freight carriers, it can be 30-40%. Last-mile delivery services often fall in the 20-30% range.
How often should surcharges be updated?
Most major carriers update fuel surcharges weekly or monthly based on published fuel index prices. FedEx and UPS, for example, adjust weekly using the US Department of Energy diesel index.
How much does a typical surcharge add per delivery?
At a 10% surcharge on a $10 base rate, each delivery costs $1 extra. For a courier handling 500 deliveries daily, that is $500/day or about $15,000/month in recovered fuel costs.
Can I pass the full fuel increase to customers?
The surcharge formula only passes the fuel portion of the increase. If fuel is 30% of your costs and fuel prices rise 25%, you pass on 7.5%, not the full 25%. This is considered industry-standard practice.
What if fuel prices drop below the baseline?
When current fuel price falls below the base price, the surcharge becomes zero or negative. Most carriers set a floor of 0% and do not offer fuel discounts, though some contracts include negative surcharge provisions.
