The Freight Rate Trend Tracker computes period-over-period percent change from two PPI values you enter — one for the prior period and one for the current period — for truckload (TL), LTL, or both. It then assigns a trend direction label and, when both segments are entered, a combined rate environment read.
Trend Direction Labels
Rising: Period-over-period change is greater than +0.5%. The PPI index level for this segment is higher than the prior period by a meaningful margin.
Falling: Period-over-period change is less than −0.5%. The PPI index level for this segment is lower than the prior period by a meaningful margin.
Flat: Period-over-period change is within ±0.5%. The PPI index level shows minimal movement relative to the prior period.
Combined Rate Environment Read
Rising: Both TL and LTL PPI readings show upward movement period-over-period.
Falling: Both TL and LTL PPI readings show downward movement period-over-period.
Flat: Both TL and LTL PPI readings are within the flat threshold period-over-period.
Mixed: TL and LTL PPI readings are moving in different directions — one rising while the other falls or is flat. When TL and LTL diverge, segment-specific readings carry more practical context than a single combined label.
Data Source
TL PPI data is published monthly by the Bureau of Labor Statistics and available free on FRED as series PCU484121484121. LTL PPI is available as series PCU484122484122. Both series update monthly with a lag of approximately 4–6 weeks. This tool contains no embedded data — all values must be entered by you.
Reference Range
The optional reference range fields let you enter a high and low value from your own observation window. The tool then shows where the current period value sits relative to that range as a percent. These reference values are ones you supply — the tool does not define or provide historical high or low benchmarks.
