PPC ROI Calculator
Forecast the profit, ROAS and cost-per-acquisition of your Google Ads or Meta Ads campaign. Adjust the inputs to see how ad spend, click cost, and conversion rate combine into real return.
Your Inputs
Projected Results
These projections are estimates based on your inputs. Actual results vary by industry, campaign quality, landing page performance, and competition. ROAS does not include management fees by convention; ROI does.
How to Use This Calculator
Five inputs determine PPC profitability. Get each one within range and the campaign should be profitable; miss two and it usually isn't.
Monthly Ad Spend
Total platform spend (Google Ads, Meta Ads, LinkedIn Ads). Below $1,500/month, most platforms can't gather enough conversion data to optimise. Australian SMBs typically run $2,000–$15,000/month per channel.
Average Cost Per Click
Get this from your platform's auction insights or historical reports. Australian CPC averages: e-commerce $1–$3, local services $3–$8, professional services $5–$15, legal and finance $15–$50+.
Conversion Rate
The percentage of clicks that complete your goal action (purchase, lead form, phone call). Australian benchmarks: e-commerce 1–4%, lead-gen 5–15%, branded search 15%+. Page speed and form length each move this 20–40%.
Average Order Value
Revenue per conversion. For e-commerce, use AOV from analytics. For lead-gen, multiply lead-to-customer close rate × average customer value. Tracking lifetime value over 12 months unlocks higher bids and better ROAS.
Management Fee
The cost of running the campaign. Australian agencies charge 10–20% of ad spend or a fixed monthly fee ($499–$2,500). For small budgets, fixed fees usually beat percentage. Below $1,000/month total spend, in-house often beats agency.
