Is your ROAS above break-even?
ROAS is ad revenue divided by ad spend. It only means profit above your break-even ROAS, which is 1 divided by your margin before ads. Here, 3.5x clears 1.85x.

Above break-even: the ads make money
What the ads leave as profit
The same $1,750 of sales, 50 orders, with every cost taken out. Profit after ads is the number to scale on, not ROAS alone.
Break-even ROAS by margin
Halve the margin and break-even ROAS doubles. A cheap product with a big cost needs ads that return far more before they pay.

More about ROAS calculator
Return on ad spend from your spend and revenue, plus the break-even ROAS your margin allows, profit after ads and the most an order can cost.
How to use ROAS calculator, step by step
- Enter spend and revenue. What the ads cost and the sales they brought in, from the same period.
- Add the product's costs. Price, cost of goods, shipping and commission. TikTok Shop's US referral fee is filled in.
- Compare ROAS with break-even. Above break-even the ads make money; under it each sale loses some.
How do you calculate ROAS?
ROAS is revenue from ads divided by ad spend: $1,750 from $500 is 3.5x. Break-even ROAS is 1 divided by your margin before ads, so a 50% margin breaks even at 2x.
ROAS and break-even ROAS, worked out
- ROAS = revenue from ads ÷ ad spend. $1,750 of sales from $500 of ads is 3.5x.
- Margin before ads = price − cost of goods − shipping − marketplace fee − commission. On the default $35 product that's $18.90, or 54% of the price.
- Break-even ROAS = 1 ÷ margin. At 54% it's 1.85x: under that, every sale the ads buy loses money.
Selling on TikTok Shop? The TikTok Shop fee calculator breaks down every fee per order, and the CPM math turns ad spend into reach.
If it doesn't work
Break-even ROAS shows no number
It needs a margin above zero: check the price is higher than cost of goods, shipping, fees and commission together.
ROAS looks too good
Take spend and revenue from the same period and campaign, and use revenue the ads brought in, not every sale.

ROAS calculator FAQ
What is a good ROAS?
One above your break-even ROAS, which comes from your margin. A product that keeps 60% of its price before ads breaks even at 1.67x; one that keeps 25% needs 4x.
How do I calculate break-even ROAS?
Divide 1 by your margin before ads: what's left of the price after cost of goods, shipping, fees and commission, as a share. At a 40% margin it's 1 ÷ 0.4 = 2.5x.
What's the difference between ROAS and ROI?
ROAS divides revenue by ad spend and ignores every other cost. ROI takes the costs out first. A 3x ROAS on a 30% margin still loses money, so the calculator shows profit too.
Does TikTok Shop's ROAS include the referral fee?
No. ROAS is revenue over spend. The referral fee, commission and your costs come out of the margin, so they're inputs for break-even ROAS.
What's a break-even CPA?
The most one order can cost in ads before it loses money: your margin per order before ads. The calculator shows it beside what an order costs you now.
