Digital Marketing ROI Calculator: Are You Getting What You Pay For?

You’re investing in Google Ads, SEO, social media, maybe even email campaigns—but is it actually working? At Mesa West Marketing, we talk to business owners all the time who are spending thousands each month on marketing and aren’t sure what they’re getting in return.

That’s why understanding your Digital Marketing ROI (Return on Investment) is crucial. Whether you’re working with an agency, managing ads in-house, or running local campaigns, knowing your ROI can help you make smarter decisions—and stop wasting budget.

Here’s how to calculate it, what to look for, and how to make sure you’re getting what you pay for.

What Is Digital Marketing ROI?

ROI measures how much revenue you earn for every dollar you spend on marketing. It’s typically calculated like this:

Marketing ROI = (Revenue from Marketing – Marketing Cost) / Marketing Cost

So, if you spent $5,000 and made $20,000 from that spend:

($20,000 – $5,000) ÷ $5,000 = 3.0 or 300% ROI

A 300% ROI means you earned $3 for every $1 spent—a strong return.

Why ROI Alone Doesn’t Tell the Full Story

ROI is essential, but not all marketing delivers immediate revenue. Some channels are about building long-term brand equity, nurturing leads, or improving customer lifetime value. That’s why you should track both direct ROI and assisted metrics, such as:

• Cost per lead

• Customer acquisition cost (CAC)

• Conversion rate

• Lead-to-close rate

• Customer lifetime value (LTV)

At Mesa West, we help clients align their metrics with their business model so they can measure both short - and long-term wins.

A Simple ROI Calculator You Can Use Today

To get started, gather the following:

• Total marketing spend (per campaign or month)

• Number of leads generated

• Close rate (the percentage of leads that become paying customers)

• Average revenue per customer

Then, use this formula:

Estimated Revenue = (Leads × Close Rate) × Average Revenue per Customer

ROI = (Estimated Revenue – Marketing Cost) ÷ Marketing Cost

Example:

• 200 leads

• 20% close rate

• $1,000 average customer value

• $5,000 ad spend

Estimated revenue = 200 × 0.2 × $1,000 = $40,000

ROI = ($40,000 – $5,000) ÷ $5,000 = 7.0 or 700% ROI

Signs You’re Not Getting What You Pay For

• You don’t know where your leads are coming from

• Ad costs are rising but conversions are flat

• Your agency can’t explain performance in simple terms

• You’re spending more on clicks than you’re earning in revenue
