How much does a digital marketing agency cost? How a quote is built

Short answer: it depends, but on things you can name

There is no standard price because “digital marketing” can mean anything from managing one Google Ads account to running social, content, the website, SEO and CRM for several brands. What does exist is a clear way to build a quote. Once you understand it, you can compare proposals and spot when something does not add up.

The three blocks of a quote

1. Agency fees. The team’s time: strategy, campaign management, community management, analysis and reporting. Charged monthly, per project or by the hour.
2. Production. Design, photography, video, web development, influencer content. It can be recurring (monthly assets) or one-off (a commercial, a website).
3. Media spend. What is paid to Google, Meta, TikTok, Amazon, Mercado Libre or traditional media. That money is not the agency’s, even when the agency manages it.

A quote that blends all three into one number makes comparison impossible. Always ask for the breakdown.

Common pricing models

• Monthly retainer. A fixed fee for a defined scope. It suits ongoing work such as social, paid media or SEO. Check what is included and what is billed separately.
• Fixed-price project. One price for a deliverable with a date: a website, a launch campaign, an audit.
• Media commission. A percentage of ad spend. Simple, but it can create an incentive to spend more; pair it with efficiency goals.
• Performance-based. Payments tied to leads or sales. It makes sense when measurement is reliable and the agency controls much of what drives results.
• Hybrid. A fixed base plus a variable component. One of the most common setups for mid-sized and large accounts.

What moves the price

Number of channels and markets, monthly asset volume, languages, technical complexity (integrations, CRM, e-commerce), reporting depth, response times and whether the agency produces or only coordinates. Two quotes for “social media management” can mean very different scopes: one includes four posts a month with no comment replies; another, daily content, community care and social listening.

In Mexico there are two administrative details: prices are usually quoted before VAT (IVA), and if the service involves agency staff dedicated to your company, check the REPSE question with your legal or tax team.

Working out media spend from your goal

A simple method is to work backwards. Suppose, as an example, your goal is 200 sales a month, your average order is 1,500 pesos and your margin lets you pay up to 300 pesos per sale in advertising. Media spend for that goal would be around 60,000 pesos a month (200 × 300). Fees and production come on top.

Your numbers will be different, and the real cost per sale only becomes clear once campaigns run. But the exercise does two things: it tells you whether the goal is realistic for your budget, and it gives you a benchmark to judge whether the campaign is on track.

Signs of a good quote

• It answers your goal and mentions your product, market and season.
• It separates fees, production and media.
• It states the monthly deliverables and how many rounds of changes are included.
• It explains how progress will be measured and how often it will be reviewed.
• It makes clear that the accounts and the data are yours.
