Core Use Case scenario
Business owners, digital advertisers, and marketing directors must evaluate the profitability of marketing investments. Calculating Return on Investment (ROI) and Return on Ad Spend (ROAS) across campaigns helps teams allocate advertising budgets to highly profitable channels.
Troubleshooting & Edge-Case Failure Points
- ROI vs ROAS: ROI measures net profit relative to total business costs. ROAS measures gross revenue generated relative to direct ad spend.
- Attribution challenges: Ensure your revenue inputs reflect actual sales generated by the campaign, using consistent attribution windows.
- Delayed conversions: Some customers click ads but purchase weeks later. Account for this delay when evaluating recent campaign performance.
Detailed Step-by-Step Instructions
- Input the total amount invested in your marketing campaign or project.
- Enter the total revenue generated from those marketing efforts.
- Add auxiliary costs such as agency fees, software subscriptions, or product costs if needed.
- Review the campaign metrics, including net profit, ROI percentage, and ROAS ratio.

How to Use the ROI Calculator
- Enter total amount invested — all-in cost, including fees, tools, and your own time if you value it.
- Enter the total return (revenue or exit value) and the holding period.
- Read ROI, net profit, ROAS, and the annualized rate so a 2-year win stops looking like a 1-year win.
- Compare two campaigns side by side — the ranking by ROI often reverses once you annualize.
How the Math Works
Annualized ROI = (1 + ROI)1/years − 1
Worked example: spend $10,000, get back $16,000 → net $6,000 → ROI 60%, ROAS 1.6:1. Over 2 years that's 26.5%/yr annualized (1.60.5 − 1) — very different from 60%/yr. An ad campaign spending $5,000 to return $20,000 has ROAS of 4:1 but if contribution margin is 30%, profit = $6,000 − wait: $20,000 × 30% = $6,000 gross margin vs $5,000 spend = 20% ROI. ROAS looks spectacular; ROI tells the truth. Always decide on ROI with margin included, not ROAS alone.
ROI FAQ
What is a good ROI?
Context is everything: S&P 500 historical average is about 10% per year nominal; a business project clearing 15-20%+ annually with tolerable risk beats it. Marketing ROI should be judged against your contribution margin, not raw ROAS.
ROI vs ROAS - which matters?
ROAS = revenue divided by spend and ignores your costs; ROI = profit over cost. A 4:1 ROAS at 20% margins is a loss. Optimize ROI.
How do I annualize ROI?
Take the nth root: (1 + total ROI)^(1/years) - 1. A 60% gain over 2 years is 26.5% per year, not 30% - compounding matters.
What costs should I include?
Everything attributable: media, tools, fees, shipping, refunds, and paid labor. Excluding your own time is fine if consistent - just do it for every compared option.
Why does my ROI look infinite?
A zero or near-zero recorded cost (organic traffic, inherited inventory). Cap the display or add a nominal cost - infinity compares badly against everything.
