How Much Should I Spend on Amazon PPC? A Beginner's Budget Guide

This is one of the first questions every new Amazon seller asks, and unfortunately the honest answer is: it depends. But that doesn't mean you have to guess. There are some practical guidelines that will help you set a starting budget that makes sense for your situation and avoid the two most common mistakes, spending too little to get meaningful data or spending too much before you know what works.

The right PPC budget depends on your product's price point, your profit margins, how competitive your category is, and what your goals are. A seller launching a $12 kitchen gadget in a crowded category needs a very different budget than someone selling a $75 specialty tool with little competition.

What you're really trying to figure out is: how much can I afford to spend to acquire a customer while still making money (or at least breaking even during launch)?

Before setting a budget, you need to know your break even point. Take your selling price, subtract Amazon's referral fee, subtract FBA fees (or your fulfillment costs), and subtract your product cost. What's left is your profit margin per unit before advertising.

For example, if you sell a product for $25, and after all Amazon fees and product costs you keep $8, then your break even ACOS is 32% ($8 / $25). That means you can spend up to $8 on ads to generate one sale and still not lose money.

This number is your anchor. Everything about your PPC budget should connect back to it.

For most new products, a daily budget of $15 to $30 is a reasonable starting point. Here's why.

You need enough spend to generate clicks, and you need enough clicks to generate meaningful data. If your average cost per click is $0.75 and you set a daily budget of $5, you're only getting about 6 to 7 clicks per day. At a typical conversion rate of 10 to 15%, that might mean one sale every two days from ads. It will take weeks before you have enough data to know which keywords work.

At $20 to $30 per day with that same cost per click, you're getting 25 to 40 clicks per day and several sales. Within one to two weeks you'll have a real picture of what's working.

If your budget is tight, $15 per day can work, but just know that the data collection phase will take longer and your optimizations will be slower.

Your PPC spending should evolve as your campaigns mature. In the first few weeks, expect to run at a loss or break even. You're buying data more than you're buying profit. This is normal and expected.

After two to four weeks, you should have enough search term data to start optimizing. Cut the keywords that aren't converting, increase bids on the ones that are, and add negative keywords to eliminate waste. Your ACOS should start coming down.

As your campaigns become more optimized over the following weeks, you can start increasing budget on the campaigns and keywords that are profitable. This is where PPC goes from a cost center to a growth engine. If a campaign is running at a 15% ACOS and your break even is 32%, you should be putting as much budget behind it as possible because every dollar spent is making you money.

A lot of new sellers set a $5 per day budget because they're nervous about wasting money. The irony is that this often wastes more money in the long run. With so few clicks per day, it takes forever to figure out which keywords work, and you're paying for all that learning spread out over months instead of weeks. You end up spending the same total amount but taking much longer to get results.

On the other end, some sellers dump $100 per day into campaigns from day one without proper targeting or monitoring. If your campaigns aren't optimized, that's a lot of budget flowing into irrelevant clicks. Higher daily budgets make sense once you know which keywords convert, not before.

If you're running both auto and manual campaigns (which you should be), split your budget roughly 40/60 or 30/70 in favor of your manual campaigns once they're running. Your auto campaign is a discovery tool and doesn't need as much budget. Your manual campaigns, targeting proven keywords, deserve the bigger share.

Increase your daily budget when your campaigns are consistently spending the full budget before the day ends and your ACOS is at or below your target. If Amazon is running out of your budget by 2pm, you're missing half a day of profitable ad impressions. Bump the budget up and capture those sales.

The key to good budget management is regularly checking which keywords are eating your spend and whether they're generating sales. This means reviewing your campaign data and search term reports at least weekly. If the manual tracking feels like a lot, ppctools.net syncs your campaign data automatically and shows you exactly where your budget is going and whether each keyword is pulling its weight, so you can make adjustments quickly without digging through spreadsheets.

The bottom line: start with $15 to $30 per day, give your campaigns two weeks to collect data, then optimize based on what the data tells you. Your budget should grow as your campaigns prove themselves profitable.

For new campaigns, $15 to $30 per day is a solid starting range. This gives you enough clicks to gather data quickly. Once your campaigns are optimized and profitable, you should increase budget on winning campaigns to capture more sales.

Subtract all non-advertising costs (product cost, Amazon fees, shipping) from your selling price. Divide that number by your selling price and multiply by 100. For example, if you sell at $25 and your costs are $17, your break even ACOS is 32%. Any ACOS below that is profitable.

Once you have both running, allocate more budget to manual campaigns (roughly 60 to 70%) since those target your proven keywords. Keep the auto campaign funded enough to continue discovering new terms, but it doesn't need as much budget as your manual campaigns.

Increase your budget when your campaigns consistently spend the full daily budget before the day ends and your ACOS is at or below your target. If Amazon is running out of your budget by midday, you're missing profitable impressions for the rest of the day.
