Taco bar calculator
Plan tortillas, proteins, toppings, sides, and real shopping packages for every guest at your table.
How the taco bar calculation works
The calculator multiplies each age group by its tacos-per-guest setting, applies the selected food buffer, and rounds each age subtotal upward. Corn and flour tortillas split evenly when you choose a mixed service, then each type rounds to a complete package.
Protein is measured as cooked, ready-to-serve food. Street tortillas use 1.25 ounces per taco, standard tortillas use 1.5 ounces, and large tortillas use 2 ounces. The dietary split allocates that total without counting any guest twice.
The portion and round-up method follows the same planning logic described by the USDA Food Buying Guide. The table below is an owned hosting allowance designed for shopping, not a nutrition serving recommendation.
Per-person topping and side allowances
| Item | Category | Allowance |
|---|---|---|
| Shredded cheese | Topping | 1 oz |
| Shredded lettuce | Topping | 1.3 oz |
| Salsa or pico de gallo | Topping | 2.5 fl oz |
| Sour cream | Topping | 1 oz |
| Guacamole | Topping | 1.5 oz |
| Diced onion | Topping | 0.5 oz |
| Cilantro | Topping | 0.3 oz |
| Jalapeños | Topping | 0.4 oz |
| Rice | Side | 4 fl oz |
| Beans | Side | 4 fl oz |
| Tortilla chips | Side | 1.5 oz |
| Queso | Side | 2 fl oz |

Plan 3 tacos per adult, 4 per teen and 2 per child, before the food buffer.
Plan 1.25 ounces of cooked filling for a street taco, 1.5 ounces for a 6 inch tortilla and 2 ounces for an 8 inch one.
Per guest, plan about 1 ounce of shredded cheese, 2.5 fluid ounces of salsa and 1.5 ounces of guacamole. Every topping rounds up to whole packages.
Assign every guest to one diet, then pick at least one protein that suits each diet. Each group’s share of the filling splits evenly across its proteins.
