The average cost of a cafeteria table can vary widely based on several factors, including size, material, design, and brand. Generally, prices can range from $100 to $1,000 or more per table. 
1. **Size**: Smaller tables, such as those seating two to four people, typically cost between $100 and $300. Larger tables that accommodate six to eight people can range from $300 to $600. Extra-large tables or those designed for more than eight people can exceed $600.
2. **Material**: The material significantly impacts the cost. Basic laminate or plastic tables are usually on the lower end of the price spectrum, ranging from $100 to $300. Mid-range options, such as those made from wood or metal, can cost between $300 and $600. High-end materials like solid wood or custom finishes can push prices above $600.
3. **Design**: Simple, functional designs are generally less expensive, while tables with intricate designs, additional features (like folding capabilities or adjustable heights), or custom options can increase the price significantly.
4. **Brand**: Well-known or premium brands often charge more due to their reputation for quality and durability. These tables can range from $500 to over $1,000.
5. **Bulk Purchases**: Buying in bulk can reduce the average cost per table, as many suppliers offer discounts for large orders.
In summary, while the average cost of a cafeteria table can vary, a reasonable estimate for a standard, mid-range table would be between $200 and $500.
