Roll-off arithmetic is useful only when the inputs come from current local records: facility fee schedules, scale tickets, route data, fuel-card prices, payroll burden, maintenance reserves, insurance, container records, customer terms, permits, and books.
This guide frames the source gaps behind the Roll-Off Dumpster Profit & Pricing Calculator. It does not publish quote advice, market rates, business strategy, waste-acceptance approval, DOT/FMCSA compliance decisions, tax treatment, or investment guidance.
Use the calculator to make assumptions visible, then verify every material input before quoting, dispatching, billing, financing, or relying on the output.
Single-Pull Input Sources
Single-pull math starts with a quote, included tons, actual tons, overage fee, facility fee, route distance, MPG, fuel price, job time, loaded labor rate, and per-pull reserve. The screen can combine those rows, but it cannot prove that any row is current or contractually recoverable.
Use facility fee schedules, scale tickets, transfer-station or recycling invoices, route records, fuel-card data, payroll burden, maintenance records, and written customer terms as the input source. Mark any placeholder as a source gap.
The app output is a review prompt. It does not decide whether a quote should be accepted, rejected, renegotiated, bundled, financed, taxed, insured, or dispatched.
Fleet Records and Utilization Prompt
The fleet screen rolls entered pulls, active containers, fixed costs, variable costs, and capital rows into monthly prompts. The utilization row is only a local arithmetic prompt; it does not prove demand, dispatch capacity, inventory adequacy, financing capacity, or safe operations.
Use dispatch records, container inventory, yard records, depreciation policy, insurance allocations, loan documents, repairs, downtime, customer terms, and bookkeeping records to populate the rows.
If utilization or contribution rows look concerning, treat that as a review trigger for records and source gaps, not as a business decision from the app.
Price-Floor Source Gap
The price-floor screen divides the entered cost stack by the entered target margin and shows lower and upper review prompts. That is cost-plus arithmetic only.
Actual pricing still needs current market evidence, customer terms, disposal facility facts, pass-through clauses, taxes, collection risk, seasonality, financing, insurance, and qualified business/accounting/legal review.
Do not treat a price-floor row as a quote, market rate, customer-acceptance forecast, or proof that a market can support the operation.
Disposal and Contract Source Gaps
Disposal cost depends on facility type, waste category, weight, contamination, special items, minimum charges, surcharges, taxes, environmental fees, rejected-load rules, and pass-through terms.
Overweight, mixed-load, prohibited-material, damage, cancellation, rental-period, collection, chargeback, lien, and tax terms belong in written customer documents reviewed outside the app.
EPA and state/local waste rules, facility acceptance policies, hazardous-waste restrictions, asbestos/lead/liquid/tire/appliance/battery handling, and hauler licensing remain source gaps until verified for the actual load and jurisdiction.
Source Gaps to Resolve
Before relying on a roll-off cost screen, resolve facility schedules, scale-ticket basis, route and access facts, customer terms, insurance, payroll burden, worker classification, truck maintenance and depreciation, container inventory, financing, taxes, accounting treatment, local waste-hauler licensing, DOT/FMCSA applicability, HOS, CDL, permits, and collection risk.
Also verify safe loading, unloading, backing, traffic control, overhead utilities, rail clearances, hoist stability, PPE, LOTO, OSHA program requirements, and site-specific hazards before dispatch.
The app can document assumptions for review. It cannot approve waste acceptance, legal compliance, safe work, financing, tax treatment, market pricing, or business viability.
