Enter one product's monthly page visitors and conversion rate. See how many shoppers and days a 50/50 price test needs to reach 95% confidence.
| Effect to detect | Visitors / group | Days |
|---|---|---|

| ±10% per visitor | 61,152 | 1224 |
| ±15% per visitor | 27,179 | 544 |
Running in parallel across 20 products, the agent could finish about 6 ±10% tests a year. Minimum 7 days per test. Estimate only — real results vary.
Give the prAIcing agent your goal and guardrails. It picks which products to test, splits shoppers 50/50, stops at 95% confidence and keeps learning from every result.
It depends on your conversion rate and the size of the effect you want to detect. Smaller effects and lower conversion rates need more visitors. The calculator uses a standard two-group test at 95% confidence and 80% power.
A higher price can convert slightly fewer shoppers yet earn more per visitor. Revenue or profit per product-page visitor captures both effects at once.
Yes. Start with your best-selling products, which reach confidence fastest, and test larger price steps (around 10%). The prAIcing agent prioritises products automatically.
We recommend at least 7 days so every weekday is covered, even when the visitor count is reached sooner.
