budget line
Financial planning category
A budget line is the set of all combinations of goods that exactly exhaust a consumer's income at given prices.
In economics, it represents the boundary of what's affordable—points below the line are within budget, points above are not.
The budget line shifts outward when income increases.
Also called a budget constraint.
