Enter the values below. Each quantity identifies its unit or meaning.

Qd = a − bP
positive coefficient
Qs = c + dP
positive coefficient

Result

Calculated from your inputs.

With Qd = a − bP and Qs = c + dP, equilibrium price = (a − c) ÷ (b + d), then Q = a − bP.

How to use this calculator

What to enter

Enter or select the following as requested: Demand intercept (a); Demand slope coefficient (b); Supply intercept (c); Supply slope coefficient (d). Follow the units, valid ranges, examples, and options displayed beside each field.

What the result means

The economic indicator or model result is calculated from the prices, quantities, income, output, employment, or index values entered. Check the time period, nominal versus inflation-adjusted values, base year, units, data source, and the assumptions used in the economic model.

When to use it

Use this to study economic relationships or compare scenarios. Interpret results in context and use consistent, current data; simplified models do not capture every market or policy factor.
