This calculator uses two data points. Zorin fits a full demand curve from your real order history — every SKU, updated automatically as new sales come in — and tells you the exact price that maximizes profit, not just revenue. Start your free trial →

How to use this calculator

Find a product where you changed the price at some point and know roughly how many units sold before and after. Enter the original price and units sold as “Price A” and the new price and units sold as “Price B.” The calculator uses the midpoint (arc elasticity) method, which gives a consistent result regardless of whether the price went up or down.

What the elasticity coefficient means

Elastic (|E| > 1): your customers are price-sensitive. A price increase reduces units sold by more than the percentage increase - revenue may fall.
Inelastic (|E| < 1): your customers are relatively price-insensitive. There may be room to raise prices without losing many sales.
Unit elastic (|E| ≈ 1): demand moves proportionally with price - revenue stays roughly flat as price changes.

This two-point calculation is a useful sanity check, but it only reflects one price change. Zorin fits a full demand curve from your complete order history, automatically excludes promotional sales spikes that would skew the result, and tells you the exact price that maximizes profit for every product in your catalog.
