The Carrier Cost Pressure Index (CCPI) computes a cost pressure spread: the difference between how much your aggregate operating costs changed (as a percentage) and how much your average freight rate changed (as a percentage). A positive spread means costs are rising faster than rates; a negative spread means rates are rising faster than costs.
Aggregate Cost % Change
The tool adds up all monthly cost categories you enter (insurance, maintenance/repair, equipment/financing, and other operating costs) for both the prior and current period. It then computes dollar-weighted aggregate percent change: (sum of current monthly costs − sum of prior monthly costs) ÷ sum of prior monthly costs × 100. This produces a single percentage representing how much your total monthly cost base shifted, weighted by the actual dollar size of each category.
Freight Rate % Change
Computed as: (current average rate − prior average rate) ÷ prior average rate × 100. This is based solely on the $/mile values you enter.
Cost Pressure Spread
Aggregate cost change % minus freight rate change %. If your costs rose 8% and your rate rose 3%, the spread is +5 percentage points — meaning costs outpaced rates by 5 points based on your entered figures.
Diesel Change
Shown separately for reference because diesel is a unit-price input ($/gal), not a monthly dollar cost. Diesel percent change is computed from the two price values you enter. It is displayed for context only and does not feed into the aggregate cost calculation — that calculation uses only the monthly dollar cost fields. If you want diesel's impact reflected in the aggregate, enter it as a monthly fuel cost in the Other Operating Cost field.
Break-Even Rate Pressure Estimate
This is an illustrative figure showing what rate per mile would need to move by if it were to fully absorb the aggregate cost change you entered. Computed as: current rate × aggregate cost change % ÷ 100. For example, if your current rate is $2.50/mile and costs rose 8%, the illustrative move is $0.20/mile. This is labeled "illustrative only" because it is a simple proportional computation — it does not account for load density, fixed vs. variable cost split, utilization, or any other operating factor. It is not a rate recommendation.
Band Thresholds
RELIEVING (spread ≤ −2): Cost growth is running behind rate growth based on entered figures.
NEUTRAL (spread > −2 and < 2): Costs and rates moving roughly in line based on entered figures.
BUILDING (spread ≥ 2 and < 6): Costs rising faster than rates based on entered figures.
CRITICAL (spread ≥ 6): Costs rising materially faster than rates based on entered figures. These band labels are descriptive only and are not a directive or recommendation of any kind.
Data Sources
This tool uses cost and rate values you enter manually — no external data is embedded. For diesel price reference, the U.S. Energy Information Administration (EIA) publishes weekly on-highway diesel prices at eia.gov/petroleum/gasdiesel/. For freight rate context, TL and LTL Producer Price Index data is available free from the Bureau of Labor Statistics via FRED: PCU484121484121 (TL PPI) and PCU484122484122 (LTL PPI).
