Free PPC ROI Calculator
A 12-month tracker that shows whether your paid campaigns generate profit, not just revenue. Enter your profit margin, ad spend, and revenue by channel, and it calculates net profit, breakeven ROAS, and cost per conversion.
This drives the breakeven ROAS calculation across all monthly tabs.
Enter ad spend, revenue, and conversions for each channel in the monthly tabs.
The spreadsheet calculates ROAS, net profit, and cost per conversion automatically.
See year-long trends across channels to identify where to scale or cut spend.
Why ROAS Alone Doesn't Tell You If You're Profitable
A 3x ROAS means you brought in $3 of revenue for every $1 of ad spend, but that number ignores what it cost you to deliver the product or service. If your profit margin is 25%, you only kept $0.75 of that $3 after costs. You spent a dollar to make seventy-five cents.
This calculator factors in what ad platforms can't see: your profit margin. It shows you the net dollars each channel puts in your pocket, or takes out of it, every month.

Frequently Asked Questions
Common questions about PPC ROI and ROAS.
ROI in marketing measures the profit generated from your marketing spend relative to what you invested. The formula is (Revenue - Marketing Cost) / Marketing Cost × 100. A positive ROI means your campaigns generated more revenue than they cost, while a negative ROI indicates a loss. For paid media, ROI differs from ROAS because it factors in your profit margin, not just revenue.
To measure paid media ROI, you need three numbers: your ad spend, the revenue attributed to those ads, and your profit margin. Calculate gross profit by multiplying revenue by your profit margin. Subtract your ad spend from gross profit to get net profit. Divide net profit by ad spend and multiply by 100 for your ROI percentage. Ad platforms only show ROAS, which ignores margin, so you need to calculate ROI separately.
A good PPC ROI depends on your profit margins. If your margin is 30%, you need a 3.33x ROAS just to break even. Anything above that is profitable. The higher your margins, the lower your ROAS can be while still generating profit. Calculate your own breakeven ROAS based on your margin, then aim to exceed it consistently.
Google cites an average return of $2 for every $1 spent, but this varies by industry, competition, and optimization. E-commerce businesses with strong margins might see 4-5x returns, while competitive B2B industries may struggle to break even. Focus on whether your campaigns exceed your breakeven point given your margins.
Breakeven ROAS is calculated by dividing 1 by your profit margin (as a decimal). If your profit margin is 25%, your breakeven ROAS is 1 ÷ 0.25 = 4.0. This means you need $4 in revenue for every $1 in ad spend just to cover costs. Any ROAS below this number loses money, regardless of how much revenue you generate.
ROAS (Return on Ad Spend) measures revenue divided by ad spend. ROI (Return on Investment) measures profit divided by investment. ROAS ignores your costs — a 3x ROAS with a 20% profit margin means you're losing money on every sale. ROI accounts for margin, showing profitability rather than just revenue.
