Calculate the ideal daily and monthly PPC budget for your e-commerce products. Plan ad spend based on target sales, CPC, and conversion rate.
How much should you spend on PPC advertising? The answer depends on how many sales you want, your average CPC, and your conversion rate. If you need 10 sales per day and it takes 10 clicks to get a sale at $0.75 per click, your daily budget is $75.
This calculator works backward from your sales goals to determine the required daily and monthly ad budget. It also estimates the resulting ACoS and total ad cost per sale, so you can validate the budget makes financial sense before committing.
Proper budget planning prevents two common mistakes: underfunding (budgets run out by noon, missing peak shopping hours) and overfunding (spending more than the product's profit can support). Whether you are a beginner or experienced professional, this free online tool provides instant, reliable results without manual computation. By automating the calculation, you save time and reduce the risk of costly errors in your planning and decision-making process.
Setting PPC budgets without calculation leads to either underspending (missing sales) or overspending (unprofitable campaigns). This calculator links your sales targets directly to required ad spend, so every dollar is part of a concrete plan. Having a precise figure at your fingertips empowers better planning and more confident decisions. Manual calculations are error-prone and time-consuming; this tool delivers verified results in seconds so you can focus on strategy.
Clicks per Sale = 1 / Conversion Rate Clicks Needed = Target Daily Sales × Clicks per Sale Daily Budget = Clicks Needed × Average CPC Monthly Budget = Daily Budget × 30 Ad Cost per Sale = Average CPC × Clicks per Sale Projected ACoS = Ad Cost per Sale / Sale Price × 100
Result: Daily Budget: $75 | Monthly: $2,250 | ACoS: 25%
Target: 10 sales/day. At 10% conversion, need 100 clicks/day. At $0.75/click: daily budget = $75, monthly = $2,250. Ad cost per sale: $0.75 × 10 clicks = $7.50. ACoS: $7.50 / $30 = 25%. If break-even ACoS is 33%, this budget is profitable with 8% ad margin.
Divide your total PPC budget strategically: Brand campaigns (15‒20% of budget) — defend your brand, highest ROAS. Category campaigns (40‒50%) — target shoppers searching for your product type. Competitor campaigns (15‒20%) — target competitor ASINs and brand names. Auto campaigns (15‒20%) — discovery of new profitable search terms.
Spreading budget too thin across too many campaigns (each campaign needs enough clicks for statistical significance). Not accounting for CPC inflation during peak seasons. Setting the same budget for all products regardless of margin. Cutting budget on profitable campaigns because the absolute spend looks high. Not adjusting for day-of-week conversion patterns.
Your bid controls how much you pay per click. Your budget controls total daily spend. You can have a high bid with a low budget (get few but expensive clicks) or a low bid with a high budget (get many cheap clicks). Optimal strategy: set bids based on your max CPC calculation, then set budget high enough that ads run all day at those bids. If budget runs out, increase budget or reduce bids.
There is no universal answer. Your budget should be derived from (1) how many sales you want from ads, (2) your CPC, and (3) your conversion rate. Use this calculator to find the right number. As a benchmark, many sellers spend 10‒15% of total revenue on advertising during growth phases and 5‒10% for maintenance.
Once your daily budget is exhausted, Amazon stops showing your ads for the rest of the day. This means you miss afternoon and evening shoppers, who often convert at higher rates. If your budget consistently runs out before 6–8pm, increase it. Check the "Budget" column in Campaign Manager for depletion alerts.
Average Amazon CPCs range from $0.50–$1.50 for most categories. Highly competitive categories (supplements, beauty, electronics) can see $1.50–$3+. Low competition niches may be $0.20–$0.60. Your actual CPC depends on bid, relevance, and competition level for each keyword.
Yes. Separate budgets for brand, category, and competitor campaigns allow independent control. Brand campaigns (high conversion, low CPC) should never run out of budget. Give them their own budget. Category and competitor campaigns can have flexible budgets adjusted based on ACoS performance.
Scale gradually: increase budget by 15‒25% per week. Monitor ACoS after each increase. If ACoS rises significantly (5%+ above target), you've hit diminishing returns. Scaling also means expanding keywords (not just spending more on existing ones). Add new keyword groups alongside budget increases.
New product launches typically require 2–4× the steady-state budget for the first 4–8 weeks. Budget for higher CPCs (you'll bid aggressively) and lower conversion rates (no reviews yet). Many sellers allocate $50–200/day for launch campaigns, accepting above break-even ACoS to build review velocity and organic ranking.
