In the physical petroleum markets, wholesale terminal “rack” prices are highly dynamic. Daily posted prices shift continuously based on refining run rates, regional pipeline allocations, crude oil movements, and localized inventory levels. Because of this volatility, the spread between the highest and lowest posted supplier prices at any single terminal can fluctuate significantly within a 24-hour window.
When organizations manage wholesale fuel purchasing operations without real-time benchmark visibility, they may incur procurement variance—the hidden premium paid when purchasing fuel at prices higher than the true regional baseline index. Over time, even a fraction of a cent in unverified price variance can lead to significant cost drift across multiple retail locations.
This interactive calculator is designed as an internal estimation tool. By inputting your average monthly purchasing volume and modeling potential regional price swings, you can immediately visualize how minor, unmonitored per-gallon variances compound over a standard 12-month period.
How this works: Wholesale fuel prices fluctuate constantly. This tool estimates your potential annual saving by calculating how much minor, unmonitored supplier price variances (the differences between the highest and lowest pricing available at your local terminal) add up over a year based on your monthly purchasing volume. Follow these steps:
Because physical infrastructure, local refining capacity, pipeline density, and regional fuel specifications (such as state-specific environmental standards) differ across North America, some regions naturally exhibit wider typical price spreads than others.
