The four questions, and why these four
This is the multiplier, not the diagnosis. A 15% waste rate is a rounding error at $400 a month and a serious problem at $40,000. Spend tells us what the percentage is worth in dollars; it does not tell us whether the account is healthy.
A high ACoS is not automatically bad — it depends entirely on your margin. What it reliably signals is loose bid discipline: more clicks bought on search terms that never convert. Below 15% usually means someone is already watching closely.
A $1.20 Sponsored Products click is a small cost against a $60 sale and a large one against a $12 sale. Low-price catalogues leak waste faster relative to spend, because the same wasted click eats a much bigger share of the order.
This is the question that does most of the work. You cannot negate a search term you have never looked at, and every other answer adjusts the number this one sets.
How the score is calculated — the actual model
Most free Amazon PPC audits will not tell you how they arrived at your number. Here is ours in full, so you can decide whether to believe it. The starting waste rate comes entirely from how often you review your search term report:
- Never or rarely — 30% assumed waste
- Every few months — 18%
- Monthly — 10%
- Weekly or more — 5%
That base figure is then adjusted twice. An ACoS at or above 50% multiplies it by 1.25, and at or above 35% by 1.10; an ACoS under 15% multiplies it by 0.85. An average sale price under $15 multiplies it by 1.10; $50 or above, by 0.95.
The result is held between 3% and 45%, because neither a perfect account nor a total catastrophe is a useful estimate from four answers. Your monthly waste is that rate applied to the ad spend you entered, and your 0-100 score is 100 minus 2.5 points for every percent of waste — 18% waste scores 55.
What each grade means
- A — 5% waste or less. You are reading your search term report weekly and acting on it; the remaining gains are in bid precision and placement, not in negatives.
- B — up to 10%. Normal for a well-run Amazon account. Worth a monthly sweep rather than a rebuild.
- C — up to 18%. The most common grade. There is a real, findable list of search terms spending money and returning nothing.
- D — up to 30%. Roughly a third of every ad dollar is buying clicks that will not convert — usually an account that grew faster than anyone had time to maintain.
- F — above 30%. Campaigns are running largely unattended. The fix is not clever bidding; it is looking at the report at all.
What this audit cannot see
It is an estimate from four answers measured against Amazon PPC benchmarks — not a read of your account. It does not know which of your search terms are wasting money, which ASINs carry the account, or whether your ACoS is profitable for your margins, and it cannot see your COGS, FBA fees, referral fee or return rate.
For the exact figure, the free PPC waste calculator reads your real search term report and returns the specific keywords bleeding budget plus a copy-paste negative list. It runs entirely in your browser — the report is never uploaded to a server.
The number that makes the grade actionable
A grade tells you how much you are wasting. It does not tell you what you can afford to spend — and that is the number most Amazon sellers have never worked out. Break-even ACoS is the highest ACoS a product can carry before it stops making money. It falls out of your landed cost, Amazon's referral and FBA fees, and your sale price, and it is different for every SKU.
Without it, a 30% ACoS is just a number: comfortably profitable on one product and losing money on the one beside it. The free break-even ACoS calculator works yours out.
Rules keep the fixes fixed. In our rule set, a keyword that spends more than $16 in 30 days without an order is paused, and so is one at 60% ACoS or more. See our Amazon PPC automation rules, with every threshold.

This quick audit estimates your waste from four questions. The deep-dive waste calculator reads your actual search term report for the exact keywords bleeding budget and a copy-paste negative list — both free.
There is no universal answer, and any number quoted without your margins is guesswork. A good ACoS is one below your break-even ACoS — the point where an additional sale stops adding profit. For a thin-margin product that might be 12%; for a high-margin one it can sit above 40% and still be worth running.
Yes. RedHen Labs reads your Amazon search terms every day. From the $69 Growth plan it surfaces negative keywords and harvests for your approval; the $129 Professional plan adds rules that apply them automatically. Both track real profit per product after COGS, FBA fees, referral fees and ad spend, for a flat price — never a percentage of your ad spend.
No. The quick audit and every calculator on this site run without an Amazon connection or a login. Connecting an account is only needed for the daily automation, which is what the paid plans do.
