Where did your shipping cost increase come from?
Separate a year-over-year shipping increase into base rate changes, fuel surcharge changes, accessorial increases and volume growth.
Results
- Fuel is computed as a percentage of each year’s transportation spend, never compounded on itself.
- The four effects add up to the total change.
How this is calculated
Volume effect, then rate effect at last year’s fuel %, then the fuel percentage change on this year’s base, then accessorials. The parts sum exactly to the total.
Rates shown as defaults come from carrier publications or each carrier’s published table applied to the EIA price; see the methodology. Estimates and examples are labeled. Results are illustrative and do not represent any carrier’s reported financial results.
Questions
Why did my shipping costs rise more than the GRI?
Fuel percentage changes, accessorial increases and fuel applied to a higher base all add to the headline GRI.
