Per-visit price follows trap size. Annual cost follows frequency, and frequency follows your menu. A bigger trap often costs more per visit and less per year, which is the calculation most kitchens never run.
A bigger trap often lowers grease trap cleaning cost
A small under-sink trap is inexpensive to service and fills fast. A large in-ground interceptor costs more per visit and holds many times the volume, so it needs servicing far less often. Over a year the larger unit frequently works out cheaper as well as safer.
Running that comparison needs real numbers rather than impressions, which is what measured fill readings provide under grease trap pumping. Two readings show your accumulation rate and therefore your true annual cost.
The trap that is genuinely expensive is the undersized one on a busy kitchen, because it needs frequent service and still passes grease between visits, producing line blockages on top of the cleaning bill.
Per visit
How it works
What moves the price
Trap size and type
Under-sink units sit at the bottom of the range and large in-ground interceptors well above it.
Condition on arrival
A trap left six months or more with solidified grease commonly costs two to three times the standard rate to bring back.
Access and location
Urban sites commonly run thirty to forty percent above national averages, and awkward access adds time.
Extra work
Hydro-jetting a line adds a few hundred, and emergency out-of-hours service carries its own premium.
The cost nobody budgets for
A blocked line under a working kitchen
Cleaning is a predictable operating cost. A grease-blocked line is not: it arrives without warning, usually at the worst possible moment, and the repair is under a floor that has service running over it.
That is the real economic case for a correct interval rather than the cheapest possible schedule. It is also why a skim that leaves the walls and the settled layer is poor value however little it costs, which is covered on grease trap cleaning.
For sites on septic rather than sewer the stakes are higher again, because grease reaching the bed destroys it. Whole-site scheduling is on restaurant septic service, and the records side on grease trap compliance.

What other jobs cost
Ranges, and what decides where in the range you land.
Small indoor traps commonly run $125 to $325 per visit and large in-ground interceptors roughly $225 to $800, with most kitchens spending $1,200 to $3,600 a year on pump-outs. Typical ranges rather than quotes.
Usually condition or location. A trap left six months or more can cost two to three times standard, and urban sites commonly run thirty to forty percent above national averages.
Frequently, because it needs fewer visits. The fill readings tell you whether the case is real for your kitchen rather than theoretical.
Ask whether the walls, baffles and outlet are scraped or whether the cap is skimmed. Those are different jobs at different prices and only one restores retention time.
Commonly a few hundred on top of the service call. It is worth it where the line has started to narrow, and unnecessary where it has not.
Only by reducing what reaches the trap. Better scraping before wash-up and proper oil disposal genuinely help; dosing products do not remove the accumulated layer.
Price per visit was fixed in writing, with a note on what would change it. After a year of monthly cleanings there has not been a single surprise line.

They explained that an interceptor costs more to service than an under-sink trap before I booked, so the invoice matched what I was told on the phone.

We were paying another outfit by the hour. Their flat rate for our trap size came in lower and the cleaning was more thorough.

Quote included the disposal manifest fee up front. Other companies added it after the fact, so this was the honest number.
