Frequently Asked Questions
How do I find elasticity for my product? +
Run a price test (A/B), look at industry studies, or use rough benchmarks: luxury goods often −2 to −3, necessities −0.3 to −0.8, addictive goods near 0.
Why does a price rise sometimes lower profit? +
If demand is elastic (|e| > 1), the volume drop offsets the price gain. Calculator shows this directly.
