Five inputs, a full picture of your unit economics
This tool runs the same math a media buyer would do before setting a budget — it just does it instantly, as you adjust the sliders.
Clicks From Budget
Monthly budget ÷ average CPC estimates how many clicks your budget can realistically buy.
Conversions From Clicks
Clicks × your website's conversion rate estimates how many of those visitors actually convert.
Revenue From Conversions
Conversions × average order value gives you estimated revenue generated by the campaign.
ROAS
Revenue ÷ ad spend — the headline number advertisers use to judge whether a campaign is working.
Break-Even ROAS
Based on your gross margin, this is the minimum ROAS you need just to cover ad spend — not yet profit.
Gross Profit
What's actually left over after product cost and ad spend — the number that matters more than ROAS alone.
What Is ROAS, and Why It Matters More Than Clicks
Return on Ad Spend (ROAS) measures how much revenue you earn for every ringgit spent on advertising. A ROAS of 4× means every RM1 spent returns RM4 in revenue. It's the single most important number for judging whether a Google Ads campaign is working — more useful than click volume, impressions, or even conversion count on their own, because it ties spend directly to outcome.
The formula is simple — Revenue ÷ Ad Spend — but the inputs that feed it (CPC, conversion rate, average order value) are where campaigns actually win or lose. This calculator lets you stress-test those assumptions before committing real budget.
What's a Good ROAS in Malaysia?
"Good" depends entirely on your margin, not a universal number. A jewellery brand with 70% margin can be profitable at 2× ROAS. A grocery delivery service with 12% margin needs closer to 8× just to break even. General benchmarks by category, based on typical Malaysian e-commerce and lead-gen accounts:
| Industry | Typical ROAS Range |
|---|---|
| E-commerce (retail, fashion) | 3× – 6× |
| B2B lead generation | 4× – 10× |
| F&B / delivery | 2× – 4× |
| High-ticket services (property, finance) | 6× – 15× |
These ranges are directional starting points, not guarantees — your actual break-even point (shown in the calculator above) is the number that should drive your decisions.
Why Gross Margin Changes Everything
Two businesses can have the exact same ROAS and completely different financial outcomes. A 5× ROAS is highly profitable for a business with 50% margin, but barely break-even for one with 15% margin. That's why this calculator includes a margin input and shows your break-even ROAS — the true minimum you need to hit before ad spend becomes profit rather than a cost.
Chasing a high ROAS number without checking margin is one of the most common budgeting mistakes we see. Always compare your actual ROAS against your break-even ROAS, not against an industry average.
How to Improve Your ROAS
- Fix conversion rate before bidding: a landing page improvement from 2% to 4% conversion rate doubles ROAS with zero extra spend.
- Tighten keyword match types: broad match without proper negative keywords is the most common cause of wasted spend we find in account audits.
- Use conversion value tracking: if you sell products at different price points, letting Google optimize toward actual revenue — not just conversion count — meaningfully improves ROAS.
- Review search terms weekly: catching irrelevant queries early prevents budget leaking into clicks that were never going to convert.
Common questions about this calculator
No — it's a planning model based on the numbers you enter. Real campaigns are affected by competition, ad quality, audience targeting, and seasonality. Use this to sanity-check a budget before you commit, not as a guarantee.
If you're already running Google Ads, both are in your Campaigns dashboard under the "Avg. CPC" and "Conv. rate" columns. If you're new to Google Ads, use the Keyword Planner for CPC estimates and your website analytics' historical conversion rate as a starting point.
ROAS is revenue divided by ad spend. Break-even ROAS is the minimum ROAS you need, given your profit margin, before ad spend stops being a cost and starts being profitable. A 4× ROAS can be excellent or barely break-even depending entirely on your margin.
Yes, ideally. Your gross margin input should reflect what's actually left after product cost, shipping, and payment processing fees — not just the raw markup on the product itself. This gives a much more accurate break-even ROAS.
Yes — adjust the budget slider and watch how clicks, conversions, and profit scale. This helps identify the point where a bigger budget still returns proportional results versus where returns start to diminish for your market.
