What is ROAS?
ROAS, or return on ad spend, is how much revenue you earn for every ringgit you spend on advertising. You calculate it by dividing the revenue from your ads by the cost of those ads. If you spend RM1,000 on ads and earn RM4,000 in revenue, your ROAS is 4, often written as 4:1 or 400%. It is the clearest way to measure whether your advertising is actually making money.
ROAS answers the question every advertiser cares about: is this ad spend paying off?
How to calculate ROAS
The formula:
ROAS = Revenue from ads / Cost of ads
- RM5,000 revenue from RM1,000 spend = 5:1 ROAS (500%).
- RM2,000 revenue from RM1,000 spend = 2:1 ROAS (200%).
A ROAS of 1:1 means you broke even on revenue (not profit). Above 1 means more revenue than spend; below 1 means you are losing money on the ads.
What is a good ROAS?
There is no universal number, because it depends on your margins. A common rule of thumb is that a 4:1 ROAS (RM4 back for every RM1 spent) is healthy for many businesses, but:
- High-margin businesses can be profitable at a lower ROAS.
- Low-margin businesses (like some ecommerce) need a higher ROAS to actually profit.
The real target is a ROAS that leaves you profitable after the cost of goods, so always work out your break-even ROAS first.

ROAS is a campaign-level metric; ROI is the bigger business picture. Use ROAS to optimise campaigns, and ROI to judge overall profitability.
Why ROAS matters
- It tells you which campaigns make money, so you can scale winners and cut losers.
- It guides budget decisions, shifting spend to the highest-return channels and products.
- It powers smart bidding. Google Ads has a Target ROAS bidding strategy that optimises toward the return you set.
- It keeps advertising accountable, tying spend to revenue rather than vanity metrics.
How to improve your ROAS
- Improve conversion rate. A better landing page turns more clicks into sales for the same spend.
- Tighten targeting, so budget goes to people likely to buy.
- Cut wasted spend with negative keywords and by pausing poor performers.
- Raise average order value with upsells, bundles, and free-shipping thresholds.
- Use Target ROAS bidding once you have enough conversion data.
- Fix tracking, because you cannot optimise ROAS you cannot measure accurately.
Frequently asked questions
What is ROAS in simple terms?
ROAS (return on ad spend) is the revenue you earn for every ringgit spent on ads. Divide ad revenue by ad cost. RM4,000 revenue from RM1,000 spend is a 4:1 ROAS.
What is a good ROAS?
It depends on your margins, but 4:1 is a common healthy benchmark. High-margin businesses can profit at less; low-margin ones need more. Always calculate your break-even ROAS first.
What is the difference between ROAS and ROI?
ROAS measures revenue per ad ringgit and counts ad spend only. ROI measures overall profit and counts all costs. ROAS optimises campaigns; ROI judges whether the business is profitable.
How do I calculate ROAS?
Divide the revenue generated by your ads by the amount you spent on those ads. For example, RM5,000 revenue from RM1,000 spend is a 5:1 ROAS.
Can ROAS be too high?
A very high ROAS can mean you are underspending and leaving growth on the table. Sometimes accepting a lower ROAS to scale volume produces more total profit. Balance ROAS with growth goals.
The bottom line
ROAS is the clearest measure of whether your advertising makes money: revenue divided by ad spend. Aim for a ROAS that keeps you profitable after your costs, use it to scale winning campaigns and cut losers, and pair it with ROI for the full picture. Measured and optimised well, ROAS turns ad spend into a predictable engine for growth.
