*National ranges for scheduled (non-emergency) service, shown so you can sanity-check any quote — including ours. Interceptor pricing usually works out to roughly $0.30–$0.65 per gallon. For a local reference point: one Baton Rouge provider’s published rates in 2025 ran a $175 service fee plus $0.50 per gallon removed, with emergency surcharges of $150–$250 — so a 1,000-gallon interceptor came to roughly $675 per visit.

What makes the price go up

• Skipped intervals. Grease that sits hardens. A neglected trap can take double the time and hose work — and gets billed like it.
• Solids left behind by cheap skim services. If a previous vendor only skimmed the cap, the compacted solids layer eventually has to come out the hard way.
• Access. A trap the truck can park beside costs less than one requiring 200 feet of hose through the dining room.
• Emergency timing. A Friday 6pm overflow costs multiples of a scheduled Tuesday 7am visit. The cheapest emergency is the one your schedule prevents.

The real number: cost per year

A $150 pump-out every 4 weeks (~$1,950/yr) beats a $250 “bargain” that skims the top, leaves the solids, and has you calling twice as often — plus one $800 emergency when the neglected trap finally backs up during Saturday service. Judge vendors on your yearly total and what actually leaves the tank, not the per-visit price.

Estimate your own schedule

The pumping frequency calculator estimates how fast your kitchen fills its trap to the 25% line, from trap size, daily covers, and how heavy your menu runs. Takes 30 seconds and you’ll know whether any quoted interval is being padded.
