Price Elasticity Calculator Quick Reference & Input Guide
Review the input parameters, allowed value ranges, and worked reference cases for the Price Elasticity Calculator below before running your calculation.
| Parameter / Scenario | Default / Sample Value | Rule or Allowed Range | Output / Usage Note |
|---|---|---|---|
| Input: Initial price | 10 | Range: 1e-09 to 1000000000.0 | Required workspace parameter |
| Input: New price | 12 | Range: 1e-09 to 1000000000.0 | Required workspace parameter |
| Input: Initial quantity sold | 100 | Range: 0 to 1000000000.0 | Required workspace parameter |
| Input: New quantity sold | 80 | Range: 0 to 1000000000.0 | Required workspace parameter |
| Worked Case 1: Baseline run (Initial price = 10) | Preloaded / test values | Find signed midpoint price elasticity from two supplied price and quantity observations | Initial price = 10; New price = 12; Initial quantity sold = 100; New quantity sold = 80. The displayed output is -1.22222222222. |
| Worked Case 2: Comparison scenario (price elasticity calculator midpoint) | Preloaded / test values | Find signed midpoint price elasticity from two supplied price and quantity observations | Initial price = 10; New price = 15; Initial quantity sold = 100; New quantity sold = 60. The displayed output is -1.25. |

Practical Worked Examples for Price Elasticity Calculator
These concrete scenarios illustrate how the Price Elasticity Calculator processes baseline inputs, comparison checks, and boundary constraints.
Baseline run (Initial price = 10)
Initial price = 10; New price = 12; Initial quantity sold = 100; New quantity sold = 80. The displayed output is -1.22222222222.
Comparison scenario (price elasticity calculator midpoint)
Initial price = 10; New price = 15; Initial quantity sold = 100; New quantity sold = 60. The displayed output is -1.25.
Boundary & unit check (Elasticity Calc)
When solving for 'elasticity calc', verify that Initial price, New price, Initial quantity sold use consistent units and stay within the documented scope: Percentage quantity change at midpoint divided by percentage price change at midpoint. Prices must differ and total quantities be positive. Descriptive two-point arithmetic, not causal demand estimation or price advice. Inputs and results use floating-point numbers; output shows up to 12 significant digits. Rounding can occur.
How to Read and Verify the Price Elasticity Calculator Output
The output panel reports the exact result derived from Initial price, New price, Initial quantity sold alongside any unit or formatting notes.
The result is the signed midpoint price elasticity. Describe the relative change between two observed price and quantity pairs.
The calculation retains the sign and uses midpoint percentages; two observations do not establish a causal demand curve.
Numerical output shows up to 12 significant digits. Floating-point arithmetic and display rounding can affect the last digits.
- Example input
- Initial price = 10; New price = 12; Initial quantity sold = 100; New quantity sold = 80
- Example output
- -1.22222222222
