Marketing ROI Calculators
A marketing ROI calculator works out your CPC, CPM, click-through, conversion rate and return on ad spend across any channel.
A marketing ROI calculator is a free tool that turns ad spend and results into a number: cost per click, cost per thousand impressions, click-through rate, conversion rate or return on investment. These metrics work on any channel, so they compare campaigns fairly.
This hub gathers our channel-agnostic marketing tools in one place. Use them to cost clicks and impressions, measure conversions and prove ROI. For platform-specific versions, see the social media hub.

What Are the Main Marketing Metrics?
Marketing metrics split into three kinds on this page. Each answers a different question.
Cost Metrics
Cost metrics price the ad: CPC per click and CPM per thousand impressions.
Rate Metrics
Rate metrics measure performance: click-through rate and conversion rate.
Return Metrics
Return metrics prove value: ROAS and SEO ROI.
How Is Return on Ad Spend Calculated?
Return on ad spend is calculated as revenue from the ad divided by its cost. A ROAS of 3 means every dollar spent returned three dollars in revenue.
Cost and rate metrics use simpler formulas: CPC divides spend by clicks, CTR divides clicks by impressions, and conversion rate divides conversions by visitors. Each tool shows its inputs.
How to Improve Your Marketing ROI
Marketing ROI improves from two directions: spend less to acquire each customer, or earn more from each one. On the cost side, cut wasted spend by pausing low-CTR ads, tightening targeting and improving landing pages so more clicks convert. On the value side, raise average order value and retention so each acquired customer is worth more over time.
Track the full funnel, not just the top. A campaign with a cheap cost per click but a weak conversion rate can still lose money, while a pricier click that converts well can be your best channel. The calculators above let you compare channels on the metric that actually matters: profit, not clicks.
Marketing Metrics Compared
| Metric | What it measures | Formula |
|---|---|---|
| CPC | Cost of each ad click | Ad spend / clicks |
| CPM | Cost per 1,000 impressions | Ad spend / impressions x 1000 |
| CTR | Share of viewers who click | Clicks / impressions x 100 |
| Conversion rate | Share of clicks that convert | Conversions / clicks x 100 |
| CAC | Cost to win one customer | Total spend / new customers |
| ROAS | Revenue per dollar of ad spend | Revenue / ad spend |
| ROI | Profit relative to cost | (Profit - Cost) / Cost x 100 |
These metrics stack into a funnel: impressions lead to clicks (CTR), clicks lead to customers (conversion rate and CAC), and customers lead to revenue (ROAS and ROI). A weak link anywhere drags the whole return down.
What Do the Key Marketing Terms Mean?
Six metrics decide how a campaign performs. Each definition below states the term in one line.
- CPC
- CPC is cost per click, the amount an advertiser pays each time an ad is clicked.
- CPM
- CPM is cost per thousand impressions, the price of a thousand ad views.
- CTR
- CTR is click-through rate, clicks divided by impressions, as a percentage.
- Conversion Rate
- Conversion rate is the share of visitors who take the action you want.
- ROAS
- ROAS is return on ad spend, revenue divided by ad cost.
- ROI
- ROI is return on investment, profit divided by cost, as a percentage.
Frequently Asked Questions
What is a good ROAS?
A common break-even ROAS is around 3 to 4, meaning three to four dollars of revenue for every dollar of ad spend, once product and overhead costs are covered. The right target depends on your margins.
What is customer acquisition cost (CAC)?
CAC is the total sales and marketing spend divided by the number of new customers it won. Keeping CAC well below the lifetime value of a customer is what makes growth profitable.
How do I measure marketing ROI?
Divide the profit a campaign generated by its cost, then multiply by 100. Track the full funnel so you credit revenue to the channel that actually drove it, not just the last click.
What Is the Difference Between ROI and ROAS?
ROAS is revenue divided by ad cost, while ROI is profit divided by total cost. ROAS looks at gross return; ROI accounts for the profit margin.
How Do I Calculate Conversion Rate?
Divide conversions by total visitors, then multiply by 100. The conversion rate calculator does it from your traffic and conversions.
What Is a Good CTR?
A good click-through rate is often 1 to 3 percent for display ads and higher for search. The CTR calculator works out yours from clicks and impressions.
Do These Calculators Store My Figures?
No. Each calculator runs in your browser, and nothing is sent anywhere unless you save a result, which stays on your device.
