I sell electronics on a 10% margin: why does the calculator say I need a 10x ROAS just to break even?

Because every dirham of sales leaves you only 10 fils before ads, so paying back one dirham of ad spend takes 10 dirhams of sales. That is what a 10x break-even ROAS means: 1 ÷ 0.10. Anything below it, even an impressive-looking 8x, means you pay the platform more than the orders earn you.

The maths, simply

Your margin before ads is what stays from each dirham of sales after the device cost, shipping, marketplace and payment fees. In electronics that slice is usually small, because device prices are well known and easy to compare everywhere. Advertising is paid out of that small slice alone, not out of the whole selling price.

That is why break-even ROAS climbs quickly as margin shrinks. At 40% you need 2.5x, at 25% you need 4x, at 10% you need 10x. The relationship is not linear: each point of margin you lose at the low end raises the required ROAS more than the one before.

Example: an 8x ROAS that loses money

A campaign for earbuds and chargers brought in 20,000 AED in sales from 2,500 AED of spend. Enter it in the ROAS calculator with a 10% margin:

  • ROAS is 8x, or 800%, and ads took 12.5% of sales.
  • Break-even ROAS is 10x.
  • Verdict: below break-even. Estimated loss after ads 500, because your gross profit was only 2,000 and the ads cost 2,500.

The same figures at a 25% margin give break-even at 4x and an estimated profit of 2,500. The campaign did not change; the product did.

What you can actually change

The result does not mean advertising electronics is hopeless. It means the fix usually lies on the margin side or in the cost of traffic, not in reading ROAS on its own:

  1. Raise the basket margin. Add higher-margin accessories and lift the average order margin to 15%, and the same campaign with 20,000 in sales and 2,500 spent clears the 6.67x break-even with an estimated profit of 500.
  2. Advertise the higher-margin products and let the thin-margin devices sell alongside them in the basket.
  3. Spend less for the same sales. At a 10% margin, spend must not exceed 2,000 for 20,000 of sales; at 1,600 the ROAS becomes 12.5x with an estimated profit of 400.
  4. Review the price. Use the Selling-price calculator to see the price that gives the margin you need, then judge whether the market will bear it.

Get the margin itself right

With low-margin products every dirham matters. Forgetting payment fees or the cost of free shipping can turn a 10% margin into 7% in reality, which pushes break-even above 14x. Work out your margin carefully in the Profit margin calculator before you enter it. The calculator also assumes one margin across all attributed sales, so if products with different margins are mixed, use an average weighted by what actually sold.

Common questions

The platform says my ROAS is excellent. Why am I losing money?

Because the platform measures sales, not profit. An 8x ROAS is excellent for a 25% margin product and a loss for a 10% one.

Is there a good ROAS for electronics?

We do not give benchmarks. The number that matters is the break-even for your own margin, which the calculator shows.

What if my margin is zero or close to it?

At zero the calculator says no ROAS breaks even, so every amount spent is a loss.
