Many can, but the profit depends on food cost, plates sold per service and fixed daily costs. In ProfitDrawer's food truck guide, 100 plates at $14 bring in $1,400; food and packaging take $450, and $600 of fuel, commissary, permits, insurance, labor and loan costs leaves $350 for the day before tax. A slow day of 70 plates cuts that by $285. These are example numbers.
The example day from the guide (your numbers will differ):
| Line | Amount |
|---|---|
| Sales: 100 plates x $14 | $1,400 |
| Food and packaging: 100 x $4.50 | $450 |
| Left after food | $950 |
| Fixed and daily costs | $600 |
| Left before tax | $350 |
That $350 has to cover days you do not work, repairs and taxes, which is why the number of service days matters as much as the menu.
What decides whether a truck makes money:
- Food cost per plate. The guide prices plates so food and packaging stay near 32% of the price.
- Volume per service. Thirty fewer plates takes $285 off the example day.
- Location and events. Private events, office lunches and catering pay a known amount and are often the most predictable income.
- Fixed costs: commissary, permits, insurance and any truck loan, which you pay on slow days too.
Track sales by location and day; after a month you will see which spots are worth the drive. As a sole proprietor, self-employment tax of 15.3% applies to net earnings of $400 or more for the 2026 tax year, on top of income tax. General information, not tax advice.
