Grease Trap Service Revenue Calculator
For grease trap cleaning operators: estimate annual route revenue, per-truck capacity, and growth potential based on your client count, service frequency, and regional pricing. Use it for route planning, hiring decisions, and business forecasting.
Know Your Route's Revenue Potential Before You Scale
Most grease trap operators grow by feel — adding clients until the truck is full, then deciding whether to hire a second driver. This calculator gives you the numbers to make that decision deliberately. Enter your current client count, average service frequency, and per-visit pricing to see your annual revenue, per-truck capacity ceiling, and what adding 10 or 25 clients would do to your top line.
The tool also models contract vs. on-demand revenue mix — because a route built on scheduled contracts has dramatically different revenue predictability than one built on reactive calls, and that difference matters when you are deciding whether to take on a second truck payment.
Note: This calculator models gross revenue only — it does not account for fuel, disposal fees, labour, vehicle costs, or overhead. Use it for top-line planning and route capacity analysis, not profit forecasting. For a full P&L model, consult your accountant with these revenue figures as the starting point.

Understanding Route Revenue and Capacity
The single most important metric for a grease trap route business is revenue per truck per year — not total revenue. Total revenue scales with truck count, but revenue per truck tells you whether each asset is working hard enough to justify its operating costs. Industry operators running well-optimized routes in mid-sized US markets typically achieve $350,000-$550,000 gross per truck per year. Routes below $250,000 per truck usually have either a pricing problem or a density problem.
Capacity utilisation — the ratio of your actual annual visits to your truck's theoretical maximum — is the second key metric. A truck running 6 stops per day at 250 working days has theoretical capacity of 1,500 visits per year. If your route requires 900 visits, you are at 60% utilisation. That is healthy headroom for growth. At 85-90% utilisation, you are at the hiring threshold — the route can absorb one more truck's worth of new clients.
Revenue mix matters for cash flow predictability, not just revenue volume. A route with 80% of revenue on scheduled contracts has predictable weekly invoicing and low client acquisition churn. A reactive route generates higher per-visit revenue (on-demand calls command a premium) but creates planning volatility — you cannot staff a second driver confidently if you do not know what next month's call volume will be.
The growth scenarios in this calculator assume the same average ticket and frequency for new clients. In practice, your first 10-20 new clients in a new market area will have lower route efficiency (longer drive times) until density builds. Factor that into hiring timelines — a second truck usually takes 6-12 months to reach the revenue efficiency of a mature route.
Route Business — Common Questions
Based on grease trap service operator data and industry benchmarks.
A single vacuum truck running a mixed route of interceptors and passive traps can typically handle 100-200 active clients, depending on service frequency and trap size mix. Routes heavy with large outdoor interceptors (requiring full pump-out, 45-60 minutes per stop) top out around 100-120 clients. Routes with a higher proportion of smaller under-sink traps (20-30 minutes per stop) can serve 180-220 clients. Route density is as important as stop count in determining true capacity.
Per-visit revenue varies significantly by trap size and region. Passive under-sink trap service runs $100-$200 per visit in most US markets. Small interceptors (up to 500 gallons) run $200-$350. Mid-size interceptors (500-1,500 gallons) run $350-$600. Large interceptors (1,500-3,000 gallons) run $600-$1,200+. Routes with a mix of trap sizes typically average $250-$450 per visit. West Coast and Northeast markets command a 15-25% premium over Midwest rates.
The conventional trigger is 80-85% capacity utilisation on your existing truck — meaning you are consistently turning away new clients or stretching intervals to accommodate volume. A second truck makes financial sense when you have enough contracted clients to guarantee the new asset reaches 50-60% utilisation within 90 days. A truck at below 40% utilisation for more than 6 months is usually a cash flow problem. Most operators find it easier to add a second driver before a second truck — testing demand with a rented or leased vehicle before committing to purchase.
Significantly. A grease trap route with 70%+ of revenue under multi-year service contracts is valued differently than an equivalent-revenue reactive route when it comes to selling or financing the business. Contracted routes have predictable cash flow, lower client churn, and are easier to staff because scheduling is planned rather than reactive. Industry rule of thumb: contracted revenue is worth 1.5-2x recurring on-demand revenue in a business valuation context.
The highest-converting channel for grease trap operators is direct outreach to restaurants near your existing route stops — you are already driving past them, and route density directly improves margins. Municipal FOG contractor lists are a source of potential clients in compliance programs who need verified service. Listing your business in verified directories means clients actively searching for a contractor in your area find you — inbound leads from operators who already know they need service convert at significantly higher rates than cold outreach.
