Zelvorm Price Lab · feature
The profit-maximising price from your elasticity and costs, kept within 10% of the prices you've actually sold at.
With a reliable elasticity e below −1, the price that earns the most profit a day is p* = (cost + shipping + fixed fee) × e ÷ ((1 − fee %) × (1 + e)). Price Lab works it out, draws profit a day across prices, and never suggests a price more than 10% outside the range you've tested, because the line can't be trusted beyond the data. When profit keeps rising to the edge, it says so and suggests testing further.
How to use it
- 1Open a product with a reliable reading and read Profit a day by price.
- 2Press Use in Commerce to change the price, or run a price test first.
