What is a good marketing budget for a fashion store?

For a fashion store, a good marketing budget usually follows the margin you keep after markdowns and returns, and the stock you can actually sell. If you sell clothes, a sale lowers your margin, so each ad euro has to bring back more. Hold sale weeks to a higher return bar than full-price weeks.

If you sell clothes, shoes or accessories

If you sell clothes, your margin is not one number. Full-price weeks, mid-season sales and end-of-season clearance each leave a different margin per order. Returns take another bite, and in fashion they can be a big one when shoppers order two sizes and keep one.

Your calendar decides part of the budget for you. A new collection or a drop pulls demand forward, and a sell-out ends it. Money spent advertising a jacket that is gone in your customer's size buys clicks, apologies and not much else.

And the work is visual. If social and video do the showing while search and email take the order, credit drifts away from where the demand was made. A budget set from last-click revenue then starves the channels that fill the top of the funnel.

What one store's export can teach a fashion budget

Below is one store's anonymised GA4 export, 1 January 2024 to 21 August 2026. It holds shares of revenue only: no ad spend, no order counts. Nothing in it says the store sells clothes, so it is not a benchmark for fashion.

The Break-even sheet is plain arithmetic: at a 40% margin, break-even ROAS is 2.5x, because 1 divided by 0.40 is 2.5. A markdown moves that bar fast. Shopify's own example is a T-shirt with a $20 price and a $10 cost: a 50% margin. Sold 25% off for $15, it shows a 33% margin in the profit report. For illustration, that takes break-even ROAS from 2x to about 3x.

That store's Channels sheet shows Paid Social at 0.0% in all three views. If you sell fashion, social may be where shoppers first see the product, so check your own export before you cut it. A zero there can mean untagged ads, or ads that work without a click.

In the Journeys sheet, 1-touch journeys carry 79.5% of revenue at 0.5 days to buy, while 2 to 3 touches carry 12.2% at 12.5 days. If your shoppers browse a collection for a week or two before buying, budget pushed into launch week pays out after it.

What the export can't show is markdowns, returns or stock. Those live in Shopify, and they move a fashion budget more than any channel report.

What changes for a fashion store?

Two bars, not one. Work out break-even ROAS at full price and again at your usual sale discount. Hold sale weeks to the higher bar, even when the dashboards light up.

Budget behind stock. Shopify's Inventory remaining per product report shows how long your tracked inventory is estimated to last, based on sales rates. Push spend toward styles with depth in the common sizes, and pull it from those about to run out.

Boost events, not the baseline. Google's seasonal budget adjustment lifts a campaign's average daily budget for 3 to 14 days, then puts it back. Use it for a drop or a short sale. Search and Shopping campaigns qualify, with exceptions such as campaigns in a shared budget.

Judge on what stays sold. Read a month's budget against net sales once its returns are in, not against the order rush.

What to do this week

1. Price your sale weeks. In Shopify admin, open Analytics, then Reports, and filter the Category to Profit Margin. Open Gross profit by product for your last sale, then for a full-price month. Pass: you have two margins and two break-even numbers. Fail: products drop out of the report because their costs are missing, so add a cost per item to your best sellers first.
2. Check stock before you push a style. In Shopify admin, open Analytics, then Reports, and filter the Category to Inventory. Open Inventory remaining per product. Pass: the styles in your ads have weeks of stock left. Fail: your ads point at variants about to run out, so move that spend now.
3. Schedule the next drop as an event. In Google Ads, click the Tools icon, open Budgets and bidding, then click Adjustments. On the Seasonal tab, click the plus button and select Budget. Pass: the boost has an end date and the budget falls back on its own. Fail: the campaign isn't eligible, so raise its budget by hand and put the reset in your calendar.

Check the homework. Your GA4 Attribution paths export already holds the evidence. Causality Engine reads that one file and shows what each channel caused next to what last-click gave it, in 1 to 2 minutes, for €99 once (excluding VAT), refundable within 30 days. Check the homework
