Budget Line Economics Diagrams: Examples & Generator

A budget line diagram is the cornerstone of consumer choice theory, showing all possible combinations of two goods a consumer can afford given income and prices. Our examples cover classic scenarios like income increases, per-unit taxes, quantity discounts, and even multi-good budgets, making it easy to grasp how constraints shift and bend.

How to

How to use a block diagram template.

  1. 01Choose the budget line template

    Start from a blank canvas or pick a pre-built example that matches your scenario, like a simple two-good budget.

  2. 02Define your budget parameters

    Enter income (I) and prices of the two goods (Px, Py). The diagram automatically plots the intercepts and connects them.

  3. 03Add shifts and bends

    Overlay additional lines for income changes, taxes, or kinks from quantity discounts. Adjust values with sliders to see real-time effects.

  4. 04Customize axes and labels

    Rename goods, set axis ranges, and add necessary annotations like 'Original Budget Line' or 'After Tax'. Use markdown for formatting.

  5. 05Export and share

    Download as PNG or SVG, or copy the shareable link. Embed in reports, presentations, or problem sets.

FAQ

Questions about block diagram templates

What is a budget line in economics?

A budget line represents all possible combinations of two goods that a consumer can purchase given their income and the goods' prices. It's a straight line with slope -Px/Py, where the intercepts are I/Px and I/Py.

What causes a budget line to shift?

Changes in income (shift outward or inward parallel) or a change in the price of one good (rotation around the opposite intercept) will shift the budget line. A price change of both goods by the same proportion also causes a parallel shift.

How do I create a budget line diagram with taxes?

A per-unit tax on a good effectively increases its price, rotating the budget line inward around the untaxed good's intercept. Use the generator to add a tax parameter and instantly see the new constraint.

Can I model more than two goods on a budget line?

The traditional diagram shows only two goods, but you can represent three by using one axis for a composite good (money spent on other goods) or by overlaying a third dimension. Our examples include a three-good scenario using smart axis labeling.
