What is the PPC ROI Calculator?
The PPC ROI Calculator estimates the return on investment of a pay-per-click campaign from ad spend, cost per click, conversion rate, and average order value. It walks the full clicks-to-revenue chain and reports two results: a simple PPC ROI based on media spend only, and a fully-loaded PPC ROI that also includes management or agency fees and creative production. ROAS is shown alongside so you can compare the media view with the profitability view.
How does it work?
The calculator converts budget into clicks using CPC, applies your conversion rate to get conversions, and multiplies by average order value to get revenue. It then computes simple PPC ROI (revenue minus ad spend, divided by ad spend), fully-loaded PPC ROI (same, but against ad spend plus fees and creative), and ROAS (revenue divided by ad spend).
Formula
(clicks x conversion rate x AOV - total cost) / total cost x 100
How the calculation works
How the calculation works
- 1Clicks = ad spend / CPC: $10,000 / $1.20 = 8,333 clicks.
- 2Conversions = clicks x conversion rate: 8,333 x 2.5% = 208 conversions.
- 3Revenue = conversions x average order value: 208 x $75 = $15,625.
- 4Simple PPC ROI = (revenue - ad spend) / ad spend x 100 = ($15,625 - $10,000) / $10,000 = 56.25%.
- 5Fully-loaded cost = ad spend + agency fees + creative = $11,500; ROI = ($15,625 - $11,500) / $11,500 = 35.87%.
- 6ROAS = revenue / ad spend = 1.56x.
Worked example
Worked Example
Keystone Outfitters, a DTC outdoor-gear brand, plans a Google Ads month with a $10,000 budget at a $1.20 CPC. It expects a 2.5% conversion rate on a $75 average order value, and pays $1,000 in management fees plus $500 in creative production.
- 1Clicks: $10,000 / $1.20 = 8,333.
- 2Conversions: 8,333 x 2.5% = 208.
- 3Revenue: 208 x $75 = $15,625.
- 4Simple PPC ROI: ($15,625 - $10,000) / $10,000 = 56.25%.
- 5Fully-loaded PPC ROI: ($15,625 - $11,500) / $11,500 = 35.87%.
- 6ROAS: $15,625 / $10,000 = 1.56x.
Result
Keystone Outfitters' campaign earns a 56% simple PPC ROI and 1.56x ROAS, but only a 36% fully-loaded PPC ROI once fees and creative are counted.
Interpretation guide
How to read your result
Revenue is below total cost; every dollar invested returns less than it costs.
Pause the worst segments, rework targeting and creative, and fix the landing page conversion rate before spending more.
Media is covered but there is little left after fees, creative, and product costs.
Push conversion rate and average order value, and watch the fully-loaded number — a great simple ROI can hide a thin real one.
A solid profitable zone for most ecommerce PPC programs after typical costs.
Scale winning campaigns gradually and reinvest into top creatives and audiences.
Strong efficiency that often signals under-spend on a proven winner.
Increase budget, expand to lookalike and retargeting audiences, and test new placements.
Benchmarks
Directional PPC ROI and ROAS by channel for ecommerce (September 2026). ROI assumes media spend only and varies heavily with your margin, AOV, and conversion rate — treat as a starting reference, not a target.
| Channel | Typical PPC ROI | Typical ROAS | Conversion-rate context |
|---|---|---|---|
| Google Search | 150-400% | 2.5-5x | 2-5% on high-intent queries |
| Microsoft Ads (Bing) | 100-300% | 2-4x | 2-3%, cheaper clicks than Google |
| Meta (Facebook / Instagram) | 50-200% | 1.5-3x | 1-3%, lower on cold audiences |
| TikTok | 30-150% | 1-2.5x | 1-3%, creative-led volume |
| Display | 0-100% | 0.5-1.5x | Under 1%, awareness-driven |
| LinkedIn (B2B) | 100-300% | 2-4x | 0.5-2%, higher AOV per lead |
Common mistakes
- - Including only media spend in the ROI denominator and ignoring fees and creative
- - Judging ROI too early, before the learning phase and attribution window settle
- - Comparing ROI across channels that use different attribution models and windows
Practical tips
Practical tips
Track PPC ROI with the same cost definitions and attribution window every period or the trend is meaningless.
Run the fully-loaded version of your numbers before leadership reports; media-only ROI flatters most campaigns.
Set break-even CPC from your AOV and conversion rate, then let Quality Score work down from there.
Raise average order value with minimums or bundles — it improves ROI without a single extra click.
Judge ROI on a 7-14 day trend, not a single day; daily PPC data is noisy.
Reconcile platform-reported revenue with your analytics tool before trusting either number.
When should you use it?
- - Planning paid search budgets from CPC, conversion, and AOV assumptions
- - Evaluating campaign profitability for weekly or monthly performance reviews
- - Comparing simple vs fully-loaded returns before scaling spend
- - Setting break-even CPC targets for new or expanded campaigns
Benefits
- - Shows the whole clicks-to-revenue chain instead of a single number
- - Reveals how much agency fees and creative production consume from the return
- - Pairs PPC ROI with ROAS so both the media view and the profit view are visible
Step-by-step example
Enter your campaign budget, CPC, conversion rate, and average order value. Add agency or management fees and creative production cost if you want the fully-loaded result. The calculator derives clicks, conversions, and revenue on the way to PPC ROI and ROAS. Compare the simple and fully-loaded numbers to see how much of your return non-media costs consume.
Real-world example
A DTC brand spends $10,000 at $1.20 per click, converts at 2.5%, and earns $75 per sale on 208 conversions, producing $15,625 in revenue. Simple PPC ROI is 56% and ROAS is 1.56x. After a $1,000 management fee and $500 in creative, fully-loaded PPC ROI drops to 36% on $11,500 of total cost.
