What is a good ACOS target on Amazon?

Good ACOS is below breakeven ACOS. If product margin before ads is 40%, breakeven ACOS 40%. Aim for 15-25% ACOS for profitable campaigns. At 25% ACOS on 40% margin you still keep 15% net. New launches may accept 40-60% ACOS for 2 weeks to gain ranking if lifetime organic compensates.

What is the difference between ACOS and TACOS?

ACOS is ad spend divided by ad sales only, measures campaign efficiency. TACOS is ad spend divided by total revenue including organic, measures overall business dependence on ads. If ACOS 25% on $1200 ad sales = $300 spend, and organic $800, TACOS = $300/$2000=15%. As organic grows, TACOS drops even if ACOS same, indicating healthy rank gains.

How is breakeven ACOS calculated?

Breakeven ACOS equals your profit margin percent before ads. Example: Sale $24.99, product $8, fulfillment $4.50, referral 15% $3.75, total costs before ads $16.25, contribution $8.74, margin 35%. If ACOS exactly 35%, ad spend equals contribution and profit zero. Below 35% profitable, above 35% losing. This calculator shows breakeven ACOS as pre-ad margin.

Lower CPC with tighter match types, add negative keywords, improve listing conversion with better main image and reviews, raise price 5% if conversion stable, shift budget from high ACOS keywords to low ACOS. If conversion rate below 8%, fix listing before bidding; if CPC above $1.50 with low search volume, lower bid and add exact match long tails.

When should I kill an Amazon PPC campaign?

Kill when ACOS stays above breakeven for 14 days with no organic lift and conversion below 5% after optimizing image, title, price, reviews. Example: breakeven 40% but ACOS 65% for 2 weeks spending $300 on $460 sales, losing $85 plus product costs. Pause, fix listing, relaunch with lower bid and exact keywords. Keep if TACOS decreasing week over week even with high ACOS, showing organic rank building.

How it works

Methodology & formulas

This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.

Calculation steps

1TotalRevenue = adSales + organicSales.
2ACOS = adSpend / adSales ×100.
3TACOS = adSpend / totalRevenue ×100.
4ROAS = adSales / adSpend.
5AvgCPC = adSpend / adClicks.
6Conversion = orders / clicks ×100.
7ReferralPerUnit = salePrice × referral%.
8ContributionPerUnit = salePrice − productCost − fulfillmentCost − referralPerUnit.
9ContributionMargin% = contribution / salePrice ×100 = breakeven ACOS.
10Estimated total units in period = totalRevenue / salePrice.
11Total COGS+fees = (product + fulfillment + referralPerUnit) × estimatedUnits.
12ProfitAfterAds = totalRevenue − totalCogsFees − adSpend.

Formulas

ACOS = adSpend ÷ adSales ×100
TACOS = adSpend ÷ (adSales+organicSales) ×100
ROAS = adSales ÷ adSpend
CPC = adSpend ÷ clicks
ConvRate = orders ÷ clicks ×100
Breakeven ACOS = (salePrice − product − fulfillment − referral) ÷ salePrice ×100
ProfitAfterAds = totalRevenue − (product+fulfillment+referral)×units − adSpend

Important assumptions

Total revenue = adSales + organicSales.
ACOS = adSpend / adSales ×100 when adSales>0.
TACOS = adSpend / totalRevenue ×100 when totalRevenue>0.
Average CPC = adSpend / adClicks.
Conversion rate = totalOrders / adClicks ×100.
Cost per order = adSpend / totalOrders.
Product cost and fulfillment per unit derived from inputs; total orders attributed influences total product and fee cost for ad sales portion, but for breakeven we use per-unit margin.
Referral fee per unit = salePrice × referralFeePercent.
Per-unit contribution pre-ads = salePrice − productCost − fulfillmentCost − referralFee.
Breakeven ACOS = contribution margin percent before ads = contribution / salePrice ×100.
Total profit after ads = totalRevenue − (productCost+fulfillment+referral)×estimated total units from totalRevenue/salePrice − adSpend.

Worked example

$24.99 product with 15% referral and $300 ad spend

$24.99 sale, $8 product, $4.50 fulfillment, 15% referral, $300 ad spend, $1200 ad sales, $800 organic, 80 orders, 500 clicks.

Total revenue $2000 (1200 ad +800 organic). ACOS 300/1200=25%. TACOS 300/2000=15%. ROAS 4x. Referral per unit $3.75, contribution per unit $24.99-8-4.50-3.75=$8.74 margin 35%. Breakeven ACOS 35%. Actual ACOS 25% below breakeven profitable green. CPC $0.60, conversion 16%, cost per order $3.75. Estimated units 2000/24.99=80. COGS+fees $16.25×80=$1300, profit after ads $2000-1300-300=$400 total, $5 per order after ads.
