Estimates only. Actual units depend on price point, glance views, replenishment, and seasonality. For a per-ASIN number anchored to live Amazon data, use the estimator above or pair it with the BSR tracker for daily history.
How the sales estimate is built
Two data sources, one answer. Nova prefers Amazon-reported actuals and falls back to a calibrated BSR model when those aren't available.
Live Amazon listing pull
We fetch the latest product snapshot from the Amazon listing: title, Buy Box price, current and 30-day average BSR, and the "bought past month" figure when Amazon publishes it.
Category-specific BSR model
When Amazon doesn't publish a monthly sales figure, we apply a per-category curve (Home & Kitchen, Beauty, Electronics, Toys, and 9 more) calibrated against real seller data.
Revenue math
Estimated units multiplied by the current Buy Box price gives estimated monthly revenue. For true profitability after fees, COGS, and PPC, plug the ASIN into the FBA calculator.
Works across every Amazon category
Nova applies a separate calibrated BSR curve for each top-level category, so a rank of 1,000 in Beauty doesn't get scored the same way as a rank of 1,000 in Books.
What sellers do with the estimate
An ASIN-level sales estimate is the starting point for product research, competitor tracking, and inventory planning.
Validate a product idea
Check the top 5-10 ranking ASINs for your target keyword. If the median seller is moving 300+ units a month at $20+, there's real demand.
Then size your unit economics in the FBA calculatorTrack a competitor
Estimate how many units a competing ASIN sells today, then watch its rank trajectory over time inside Nova's BSR tracker.
BSR tracker for daily rank historyPlan inventory for a launch
Use the estimated monthly demand at a target BSR to forecast how many units to manufacture for your first PO.
Pair with Nova's inventory analyticsPitch a wholesale or PL deal
Brand owners and agencies use ASIN-level monthly sales to size opportunity decks before approaching a manufacturer or a retail partner.

How Nova's estimator is different
Most free estimators ask you to pick a category and type a BSR by hand. Nova starts from the ASIN.
| Capability | Typical free estimator | Nova sales estimator |
|---|---|---|
| Input | Pick category + paste BSR manually | Paste any 10-character ASIN |
| Data source | BSR curve only | Amazon-reported monthly sales when available, BSR model as fallback |
| Buy Box price | Not included | Live, pulled from the listing |
| Marketplace coverage | Usually US only | US in the free tool, 21 marketplaces inside Nova |
| Signup required | Often yes after 1-2 lookups | First lookup free, email after that |
How the estimate is calibrated
Nova builds a separate BSR-to-units curve for each top-level Amazon US category, fitted on hundreds of thousands of real seller orders moving through the platform every month. When Amazon publishes a "bought past month" figure on the listing, Nova passes that exact number through instead of estimating. For ranks under 50,000 the estimate typically lands within 20-40% of actuals; accuracy degrades for very fresh listings and very long-tail SKUs where Amazon's own rank signal becomes noisier. Live ASIN data is refreshed on demand so the BSR and Buy Box price you see match the current listing.
