Budget Constraint Calculator Excel Template

This template calculates the budget line intercepts (X and Y), slope, opportunity cost of Good X in terms of Good Y, and an equal-spending bundle. It also includes optional comparative statics to show how changes in income or prices shift the budget line.

This template models the classic two-good budget constraint from introductory microeconomics. For more than two goods, you would need to extend the model or use a different framework, as visualizing budget constraints becomes more complex in higher dimensions.

Enter a new income, new price for Good X, or new price for Good Y in the optional fields. The template will calculate the new intercepts and slope, allowing you to see how the budget line shifts (parallel shift for income changes) or pivots (for price changes).
