equilibrium price
B2/C1Technical/Economic, Formal, Academic
Definition
Meaning
The price at which the quantity of a good or service demanded by consumers equals the quantity supplied by producers, resulting in a stable market with no tendency for the price to change.
In a broader sense, a state of market balance or stability where opposing economic forces of supply and demand are equal. It represents the 'market-clearing' price where there is neither excess supply (surplus) nor excess demand (shortage).
Linguistics
Semantic Notes
This is a technical economic term used as a compound noun. The concept is central to market theory. While 'equilibrium' can be used in other contexts (physics, psychology), 'equilibrium price' is specific to economics. It is often used as a benchmark or theoretical ideal.

By CEFR Level
- (Not typically taught at A2)
- If demand is high and supply is low, the equilibrium price will be high.
- On the graph, the equilibrium price is where the two lines cross.
- The government's new tax pushed the equilibrium price higher than consumers were willing to pay.

Learning
Memory Aids
Mnemonic
Think of a SEE-SAW (or TEETER-TOTTER). Supply is on one end, Demand on the other. The EQUILIBRIUM PRICE is the exact point in the middle where the see-saw balances perfectly and doesn't move.
Conceptual Metaphor
BALANCE / SCALES OF JUSTICE (The market is a set of scales; supply and demand are weights; the equilibrium price is the point where the scales are level).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation of components ('равновесная цена' is the correct economic term, not 'цена равновесия' which is a calque).
- Do not confuse with 'рыночная цена' (market price) unless context confirms the market is in equilibrium.
- The concept is abstract; Russian speakers might try to translate it as 'устойчивая цена' (stable price), which is a related but not identical idea.
Common Mistakes
- Using 'equilibrium price' to mean any stable price, even one set by a monopoly or government (technically incorrect).
- Saying 'the equilibrium price is the best price' (it is a descriptive, not normative, concept; it may not be 'fair' or 'best').
- Pronouncing 'equilibrium' with stress on the third syllable (e.g., e-qui-li-BRI-um) instead of the second (e-qui-LIB-ri-um).

FAQ
Frequently Asked Questions
No. 'Equilibrium' is a descriptive, not a moral or judgmental, term. It simply describes the price that balances quantity supplied and demanded. It may not account for externalities (like pollution) or be fair to all parties.
Yes. The equilibrium price is not fixed. Any change in the determinants of supply (e.g., input costs, technology) or demand (e.g., consumer income, tastes) will shift the supply or demand curve, creating a new equilibrium price.
In reality, markets are often in a state of dynamic adjustment, moving towards equilibrium but not always perfectly achieving it due to constant changes in information, expectations, and external factors. It is a powerful theoretical benchmark.
The 'market price' is the actual price you observe at any given moment. The 'equilibrium price' is the specific market price at which the market would be in balance. If the observed market price is not the equilibrium price, market forces will tend to push it towards equilibrium.
