Budgeting from a sales goal
Most sellers set an ad budget by feel and then wonder why results swing month to month. A cleaner approach is to start from the outcome. Decide the ad-driven revenue you want, then decide the share of that revenue you can afford to spend on ads, which is your target ACoS. Multiply the two and you have a budget that matches your goal.
To use the tool, enter your target monthly ad sales and your target ACoS. The recommended monthly budget appears instantly, along with a daily figure so you can set campaign caps that pace evenly through the month. If you know your average cost per click, add it to estimate how many clicks the budget should generate.
Treat the result as a starting point, not a ceiling. As listings convert better and campaigns mature, your real ACoS usually falls below the target, which means the same budget delivers more sales. Review the numbers monthly and adjust the target as your margins and goals change.
PPC budget calculator FAQ
How much should I spend on Amazon PPC?
Work backwards from a goal rather than guessing. Decide how much ad-driven revenue you want and the ACoS you can afford, then multiply the two. If you want $10,000 in ad sales at a 25 percent target ACoS, that points to a $2,500 monthly budget. This calculator does that for you and splits it into a daily figure.
How is the daily ad budget worked out?
It divides your recommended monthly budget by 30.4, the average number of days in a month. Amazon spends against daily caps, so a steady daily budget keeps campaigns running all month instead of burning out early. Leave a little headroom on strong-selling days when ads are most profitable.
What if my actual ACoS is higher than my target?
Then you are either spending more to hit your sales goal or falling short of it. Tighten bids on weak search terms, add negatives, and improve listing conversion so each click is worth more. As your real ACoS drops toward the target, the same budget buys more sales.
