📐 Formula
💡 Practical Example
Setting optimal prices for a software or retail product with $40.00 unit marginal cost and an estimated price elasticity of -2.50: Yields a $66.67 profit-maximizing price point and a 40.00% gross margin.

Microeconomic Pricing Theory & Profit Maximization
In microeconomics, a firm maximizes total profit where Marginal Revenue (MR) equals Marginal Cost (MC). Connecting Marginal Revenue to Price Elasticity of Demand (E_d) yields the famous Amoroso-Robinson Pricing Equation.
Core Optimal Pricing Equations
- Amoroso-Robinson Rule: P^* = MC ×
- Optimal Gross Margin: Margin (\%) = 100\% = ( (-1) / (E_d) ) × 100\%
- Optimal Markup on Cost: Markup (\%) = 100\% = 100\%
- Lerner Index of Market Power: L = (P^ - MC) / (P^) = (-1) / (E_d)
Elastic vs Inelastic Price Sensitivity
- Inelastic Demand (-1 < E_d < 0): Customers are insensitive to price; raising prices increases total revenue.
- Elastic Demand (E_d < -1): Customers are sensitive to price; optimal pricing balances unit margin against volume loss.
Dynamic Pricing Algorithms & Demand Curve Calibration
SaaS revenue managers and e-commerce algorithmic repricers continuously fit demand curves to sales velocity data, updating E_d coefficients dynamically across seasonal shopping periods.
How to Use This Calculator
Enter your Marginal / Unit Cost (MC) (e.g. 40.00 in ), Price Elasticity of Demand (Ed) (e.g. -2.5), and Monthly Fixed Overhead Costs (e.g. 10000.00 in ). Results update instantly as you type — adjust any value to compare scenarios.
The Formula
Optimal Price: P = MC (Ed / (1 + Ed))
Worked Example
Setting optimal prices for a software or retail product with 40.00 unit marginal cost and an estimated price elasticity of -2.50: Yields a 66.67 profit-maximizing price point and a 40.00% gross margin.
Understanding Your Result
Evaluate your result in the context of your specific use case and relevant industry standards or reference values. A single calculated result is a starting point — test two to three scenarios to understand how sensitive the outcome is to your key input assumptions. For high-stakes decisions, verify your result against a secondary source or subject-matter expert before acting.
💡 Mathematical Rigor & Applied Context
- This calculator applies exact mathematical definitions following conventions established by NIST and international standards bodies.
- Rounding errors accumulate across multi-step calculations. For precision-critical work, maintain extra significant figures through all intermediate steps.
- Many mathematical concepts have multiple valid formulations — if a result seems unexpected, verify which convention or definition applies to your context.
- Dimensional analysis (unit tracking) is the fastest way to catch formula errors. Every term in an equation must have consistent, compatible units.
- Numerical methods used in digital calculators introduce floating-point precision limits (~15 significant digits for IEEE 754 double precision).
- For statistical and probabilistic calculations, always specify whether you are working with population parameters or sample statistics — formulas differ.
- Visualizing a problem geometrically or testing with known boundary values (zero, infinity, negative) reveals hidden errors faster than algebraic checking.
- When in doubt, validate your result against a simplified hand calculation or a published worked example from a textbook or standards document.
