Price Elasticity for Non-Economists: A Retail Guide
If I raise prices 10%, will I sell 10% less? The answer is never that simple — but it's calculable.

Price elasticity is the single most useful concept in retail pricing, and the most underused. Simply put, it measures how much demand changes when price changes.
If you raise the price of a jacket by 10% and sales drop by 5%, the elasticity is -0.5 (inelastic — you should probably raise the price). If sales drop by 15%, the elasticity is -1.5 (elastic — the price increase hurt).
Why Most Retailers Don't Calculate It
Because it requires historical price-quantity data, statistical modeling, and controlling for confounding variables (seasonality, promotions, competitor actions). A proper elasticity study takes a data scientist 2-3 weeks.
The AI Shortcut
An agent can estimate elasticity from your existing sales data in seconds. It's not as rigorous as an academic study, but it's directionally correct — and infinitely better than guessing.
"What happens if I raise prices 15% on denim?" The agent models the demand shift, calculates the margin impact, and shows you the net effect. If revenue goes up despite lower volume, that's your answer.
