# Budget Line vs. Budget Set: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on December 30, 2023
"A budget line represents the combination of goods a consumer can purchase with a specific budget, while a budget set encompasses all possible combinations within the budget."

## Key Differences

The budget line is a graphical representation showing all combinations of two goods that can be bought with a given budget at specific prices. The budget set, however, includes all possible combinations of goods that can be purchased within a budget constraint.
