How each number is worked out

Every result comes from the figures you enter, with these formulas. Percentages are entered as percentages: 15 means 15%.

Landed cost
(product + packaging + freight) × (1 + bank fee %)

What one unit costs to get to Amazon. The bank fee is charged on what you pay suppliers and shippers, not on the sale.

Referral fee
price × referral rate

With a tier: threshold × rate, plus the part of the price above the threshold × the rate above it. Never less than the minimum fee.

Amazon fees
referral fee + FBA fulfilment + storage

Enter the rates for your category and size tier from Seller Central. The calculator ships no fee table, because Amazon's fees change.

Profit per unit
price − landed cost − Amazon fees

Before advertising. Margin is profit per unit ÷ price.

Break-even ACoS
profit per unit ÷ price

The share of a sale you can spend on ads before the sale stops making money. It is your margin before ads. Break-even ROAS is 100 ÷ break-even ACoS.

Target ACoS
break-even ACoS ÷ keep of margin

With keep of margin at 2, ads may take half the margin and you keep the other half.

Max cost per click
price × target ACoS × conversion rate

The ad budget for one sale, spread over the clicks that sale takes. Shown for your conversion rate and for 2% to 20%.

Allowable TACoS
monthly ad spend ÷ all monthly sales revenue

Ad spend is sales a month × (1 − organic share, capped at 95%) × price × target ACoS. ACoS counts only ad sales; TACoS counts every sale.

Payback
total investment ÷ monthly profit

Total investment is stock (landed cost × sales a month × months of stock) plus launch marketing and one-off launch costs. Monthly profit is profit per unit × sales a month. Return a month is the same fraction upside down.

Break-even price
the lowest price where price − landed cost − Amazon fees ≥ 0

Found by trying prices with your referral fee applied as Amazon charges it, minimum fee and tiered rate included, so below it every unit loses money. It shows — when no price covers the costs, such as with a 100% referral rate.

Billable weight and girth
greater of weight and L × W × H ÷ 139 (in, lb) or ÷ 5000 (cm, kg)

Girth is the longest side plus twice the other two. Use them to look up your size tier.

Questions

What is break-even ACoS?
The share of a sale's price you can spend on ads before that sale stops making money. It is your profit per unit before ads divided by the price, so it equals your margin. The calculator works it out from your price, costs and Amazon's fees.
What's the difference between ACoS and TACoS?
ACoS is ad spend divided by the sales the ads brought in. TACoS is ad spend divided by all your sales, organic ones included. Allowable TACoS here is the ad spend your target ACoS allows on the units you expect to sell through ads, divided by all your sales revenue.
Does the calculator know Amazon's fees?
No. Referral rates and fulfilment and storage fees depend on your category and size tier, and Amazon changes them, so you enter yours from Seller Central. The calculator applies what you enter, including a tiered referral rate and a minimum fee.
Is anything I enter saved?
No. The figures are worked out in your browser and aren't sent anywhere or saved. There's no sign-in.
How does this help with my Amazon PPC campaigns?
Enter your break-even ACoS when you upload a Sponsored Products search term report to the Amazon PPC audit, and it lists the searches selling at an ACoS more than 5% above it. The upload audit is in beta and needs a free account.
