Standard contribution-margin and breakeven analysis (managerial accounting)

Food Truck Per-Event Profit Calculator

Run the unit economics on a single food-truck event before signing the vendor agreement: gross revenue from average ticket and expected covers, food cost as a percentage of ticket, labor at hourly wages times workers times event hours, fuel and diesel for the round-trip drive and on-site idling, the event fee (flat dollar amount OR percentage of gross revenue — large festivals commonly take 10% to 30%), the commissary day-rate allocation if the operator has a monthly commercial-kitchen contract, single-use supplies, and an explicit truck depreciation reserve per event. Outputs contribution margin per cover, breakeven covers, projected net profit, and profit per hour — the four numbers needed to compare a farmers market against a corporate catering against a downtown festival on apples-to-apples terms.

FDA Food Code (current edition) commissary requirements for mobile food units

Commissary vs Private Kitchen ROI Calculator

Screen the build-or-rent decision for a food-truck commissary kitchen. Most U.S. jurisdictions require licensed mobile vendors to be commissioned out of a commercial kitchen — operators choose between renting space at a commissary kitchen ($400 to $1,200 per month plus markups) or building a private commercial kitchen ($40,000 to $250,000 capital). This calculator models monthly net cost under each option (rent including operator-time opportunity cost, build including debt service and utilities), the breakeven build-out cost over a 5-year planning horizon, and an approximate 5-year IRR on the build decision. The recommendation flags build, rent, or borderline based on a 10% monthly-savings buffer.

Standard menu-engineering framework (Kasavana and Smith

Food Truck Menu Price Optimization Calculator

Run menu engineering on a high-volume mobile food operation: compute contribution margin per item, throughput-constrained total event CM, and recommended price increases on plowhorse items (high volume, low margin) using the standard menu-engineering quadrant framework. Inputs the menu list (food cost, sell price, units per event for each item), the throughput cap in orders per hour, event service hours, and the operator's target food cost percentage (industry typical 28% to 32%). Outputs per-item contribution margin, food cost percentage, target sell price at the operator's target, total event CM, throughput utilization, blended food cost percentage, and the recommended CM uplift from moving flagged items to the target price.
