Enter your monthly ad spend, cost per click, conversion rate and average sale or client value to instantly see your clicks, conversions, revenue, profit and campaign health rating. The calculator also shows you what happens to your profit if you double your current spend.
Most business owners running Google Ads know their spend. Some know their revenue. Very few know their actual profit after ad costs, and fewer still know whether their campaign health is where it needs to be.
That is what this calculator shows you. Enter your monthly ad spend, your average cost per click, your conversion rate and your average client or sale value. The calculator does the rest, showing you exactly how many clicks your budget is buying, how many of those are converting, what revenue those conversions generate and critically, what your actual profit looks like after the ad spend comes out.
The calculator gives you five outputs to pay attention to.
Clicks from budget. How many clicks your monthly spend is buying based on your average CPC. If this number seems low relative to your spend, your cost per click may be higher than it should be for your industry or campaign structure.
Conversions estimated. Your clicks multiplied by your conversion rate. This is the number of leads or sales your campaign is producing each month. If this is low, the problem is either your targeting, your landing page or both.
Revenue from ads. Your estimated conversions multiplied by your average client or sale value. This is the gross revenue your ads are generating before any costs are deducted.
Profit after ad spend. Revenue from ads minus your monthly ad spend. This is the number that actually matters. A campaign generating strong revenue but thin profit after spend needs attention before it is scaled.
Campaign health rating. The calculator assesses your overall campaign efficiency based on your inputs and gives you a health rating alongside your ROAS. Use this as a quick pulse check on whether your current setup is performing, underperforming or needs urgent attention.
If your numbers are not where they should be, the problem is almost always in one of four places.

Frequently Asked Questions
Four things: your monthly ad spend, your average cost per click, your conversion rate and your average sale or client value. All four are available in your Google Ads dashboard. If you are new to ads and do not have real data yet, use industry benchmarks as a starting point to model potential outcomes before you commit budget.
ROAS stands for Return on Ad Spend. It is calculated by dividing the revenue generated by your ads by the amount spent on those ads. If you spend $2,000 and generate $8,000 in revenue, your ROAS is 4x. It measures how much revenue each advertising dollar produces but does not account for your broader business costs, so always read it alongside your actual profit figure.
It depends on your margins and business costs. As a general benchmark, most well-run Australian service campaigns sit between 4x and 8x. If you are consistently below 3x, your campaign needs attention, whether that is in the targeting, the landing page or the offer itself.
No. Conversion rate optimisation is about getting more from your existing traffic, not buying more of it. Better design, stronger copy, faster load times and clearer calls to action can all move the needle without touching your advertising budget at all.
The campaign health rating gives you a quick assessment of your overall ad efficiency based on your inputs. A strong rating means your spend, CPC, conversion rate and client value are working together efficiently. A weak rating flags that one or more of those inputs is pulling your overall profitability down and needs to be addressed before you consider scaling.
Start with your landing page conversion rate, then your keyword match types, then your Quality Score in Google Ads. In our experience auditing Australian campaigns, the most common culprit is traffic being sent to a page that was not built to convert. Our post on how much Google Ads management costs in Australia also covers what a properly managed campaign should include.
Yes. Enter an estimated monthly budget, a realistic cost per click for your industry, a conservative conversion rate and your average client value to model what a campaign could generate before spending anything. Our Google Ads foundations guide is worth reading first if you are starting from scratch.
