Runs entirely in your browser — nothing is uploaded. ### How the bid adjustments are worked out Good dayparting is not “where did I spend?” — it is “which hours pay off, and which quietly bleed?” The tool answers that from each hour’s **ACoS**, nudging every hour’s bid toward your account-wide average: raise where an hour runs more efficiently than your average, ease off where it runs above. Because ACoS already folds in both what a click costs (CPC) and what it returns (revenue per click), it catches the most common leak — paying peak prices midday when competition spikes, even though those hours convert no better than cheaper overnight ones. Two things keep it honest. Every adjustment is **weighted by click volume**, so a lucky overnight hour with a handful of clicks can’t trigger a reckless swing — only hours with real traffic move much. And the headline “reclaimable spend” is the actual money sitting in hours above your average ACoS, not a guess. Switch the metric on the chart to see the full picture: revenue per click, conversion rate, CPC and demand all shift through the day. Sanity-check the hours you trim against your [break-even ACoS](https://autron.ai/tools/acos-calculator) so you keep the ones that are still profitable, just less so.

FAQ ### Common questions ### What is dayparting on Amazon? Dayparting (or ad scheduling) means adjusting bids and budgets by hour of day so you spend more when shoppers convert and less when they do not. Conversion rates on Amazon vary a lot across the day, so flat 24/7 bids overpay in dead hours and underbid during peaks. ### How do I get hourly performance data? Pull an hour-of-day report from your ads platform, or aggregate your campaign data by hour and paste three columns: hour, spend and sales. The tool accepts 0–23 or 12am/1pm style hours and auto-detects the columns. ### Does Amazon support dayparting natively? Amazon's native scheduling is limited, so dayparting is usually done with budget rules or an automation tool that adjusts bids by hour. This calculator shows you where the opportunity is; acting on it every hour is what a tool like Autron automates. ### Is my data safe? Yes. Everything runs in your browser and nothing is uploaded.
