What Is ROAS?
ROAS (Return on Ad Spend) shows how much revenue each 1 TL generates you spend on advertising. It is the most common way to measure performance on Google, Meta and marketplace ads.
ROAS = Reklamdan Gelen Ciro / Reklam Harcaması
If you spent 1,000 TL and generated 4,000 TL in revenue, your ROAS is 4 (also written as 4x). In other words every 1 TL you spent returned 4 TL of revenue.
The Difference Between ROAS and ACOS
They are two sides of the same information:
| Metric | Formula | What it tells you | The good part |
|---|---|---|---|
| ROAS | Revenue / Spend | How many times it returned | High |
| ACOS | Spend / Revenue × 100 | What % of revenue went to ads | Low |
A ROAS of 4 means an ACOS of 25%. Marketplaces tend to speak in ACOS and ad platforms in ROAS — both say the same thing.
⭐ What Counts as a Good ROAS? It Depends on Your Margin
Online you'll see a single figure such as "a good ROAS is 4"; that is misleading. The right threshold depends on your own profit margin:
Break-even ROAS = 1 / (Gross Profit Margin / 100)
- If your margin is %50, break-even ROAS is 2,00
- If your margin is %35, break-even ROAS is 2,86
- If your margin is %20, break-even ROAS is 5,00
So for a seller on a 20% margin, a ROAS of 4 is a loss, but for a seller on a 50% margin the same ROAS is comfortably profitable. If you don't know your margin, work it out first with the profit margin calculator.
High ROAS but No Profit — Why?
ROAS looks only at revenue; it does not see these items:
- Product cost — most of the revenue goes here
- Shipping — especially if you offer free shipping; Shipping Cost Calculator
- Marketplace commission — Commission Calculator
- Returns — a returned order shows up in revenue but not in profit
That's why, when you enter your margin in the calculator above, we also compute the net profit line — that's where you see whether the advertising truly pays.
Frequently Asked Questions
What is ROAS and how is it calculated?
ROAS = Ad Revenue / Ad Spend. Spend 1,000 TL and generate 4,000 TL and your ROAS is 4 (4x).
What counts as a good ROAS?
It depends on your margin. Break-even ROAS = 1 / (margin/100). At a 35% margin that's 2.86; below is a loss, above is profit.
What's the difference between ROAS and ACOS?
They are inverses. ROAS = Revenue/Spend, ACOS = Spend/Revenue × 100. A ROAS of 4 means an ACOS of 25%.
How is break-even ROAS calculated?
1 / (Gross Profit Margin / 100). At a 40% margin that's 2.5; at a ROAS of 2.5 you neither profit nor lose.
My ROAS is high — so why am I not profitable?
ROAS looks only at revenue; it ignores product cost, shipping, commission and returns. On a thin margin, even a high ROAS can produce a loss.
