The year 2025 was marked by the consolidation of Artificial Intelligence and a drastic change in consumer behavior. Now, faced with the blank page of annual planning, the question that keeps every manager awake at night is: " Where should I put my money to grow safely? ". Defining the Digital Marketing budget for 2026 is no longer just about deciding how much to spend on Google Ads or Meta Ads. It's about financing an operation that is, at the same time, efficient, innovative, and resilient.
However, many e-commerce businesses still make the mistake of only looking at the past, replicating the previous year's budget with a simple inflation adjustment. Unfortunately, this strategy is a recipe for stagnation. The market has changed, media costs have risen, and new technologies have emerged. Therefore, in this guide, we will deconstruct the budget planning process. You will learn how to build a budget based on realistic goals, diversify investments, and prepare your cash flow for the trends that will dominate 2026.
1- Auditing the Present: Looking Back with Intelligence
First and foremost, you can't plan for the future without deeply understanding the past. However, it's not just about looking at total revenue. You need to thoroughly analyze the efficiency of every penny spent in 2025.
Basically, your audit should answer three basic questions:
- What was the CAC (Customer Acquisition Cost) By channel? Has Google Ads become more expensive? Has organic traffic (SEO) delivered a real ROI?
- What was the retention rate (LTV)? How much of your revenue came from repeat customers versus new customers?
- Where was there waste? Tools that were hired but not used? Test campaigns that ran for too long without results?
In this way, you create a "baseline." If your CAC increased by 20% in 2025, your Digital Marketing budget for 2026 needs to account for at least that variation to maintain the same sales volume. If the goal is growth, the investment will have to be proportionally larger or more efficient.
2- Defining the Method: Zero-Based Budgeting vs. Historical Data
Here we enter a vital strategic decision. Generally, companies use the historical budget (last year's + X%). However, for 2026, we recommend a different approach.
Zero-Based Budgeting?
In the corporate world, there is a concept called Zero-Based Budgeting (ZBB ).
Unlike the traditional method, where you take the previous year's budget and simply make adjustments, in Zero-Based Budgeting you start from scratch , literally. You must justify each new expense for the new period, without taking into account what was spent before.
For example: just because you spent R$ 50 on influencers in 2025 doesn't mean you should spend R$ 55 in 2026. In ZBB, you ask: “ Do influencers still make sense for our 2026 goal? If so, how much do we need to achieve objective X? ”. This eliminates “fat,” investment biases, and forces the manager to think strategically about each channel.
3- The 70/20/10 Rule for Media Allocation
With the total value defined (generally between 5% and 15% of projected revenue, depending on the aggressiveness of growth), how do you divide that pie?
To ensure safety and innovation, we suggest the 70/20/10 methodology :
70% of the budget – the “ bread and butter ” (proven performance): this is where the money that pays the bills goes. In other words, channels that already deliver a guaranteed and predictable ROI . For most e-commerce businesses, this means Google Ads (Shopping and Search), Meta Ads (bottom of the funnel), and Email marketing/CRM.
- Tip for 2026: Reserve funds here for the automation of these channels via AI.
20% of the budget – expansion (new secure channels): here you invest in what you need to grow so you don't depend solely on Google/Meta. For example: SEO (content), Pinterest Ads (excellent for discovery), Influencer Marketing , and Retail Media (if you sell on marketplaces).
- Objective: Find the next performance channel.
10% of the budget – innovation (betting): finally, reserve a portion for aggressive testing . If you don't test, you'll be swallowed up by the competition that has.
- Ideas for 2026: Campaigns on emerging channels, tests with new video AIs, or unusual collaboration partnerships. If it goes wrong, you only lost 10%. If it goes right, you struck a goldmine before everyone else.
4- Predicting the “Invisible” Costs of 2026
Often, planning fails because it doesn't consider costs that aren't paid media . However, in modern marketing, infrastructure is expensive.
In your Digital Marketing plan for 2026 , include specific lines for:
Technology and tools ( Martech )
Can your CRM handle the load? Do you need a CDP ( Customer Data Platform ) tool to unify data? The cost of e-commerce platforms (such as VTEX or Nuvemshop ) and automation tools ( RD Station ) should be factored in. Additionally, consider the cost of the Generative AI tools your team will use for productivity.
Content production
With the rising cost of media, the creative element (video, image, text) is what makes the difference in CTR. Therefore, you need a budget for production . This includes videographers, designers, or automated creation platforms. Having a media budget is useless if the ad is ugly and doesn't convert.
People and training
Technology changes rapidly. Therefore, set aside a budget for team training or to hire specialized consultants ( such as e-Plus ) who can bring this know-how in-house.
5- The Disbursement Schedule: Seasonality is Everything
A classic mistake is dividing your annual budget by 12 and spending the same amount every month. However, in e-commerce, this is fatal.
Your budget should follow the demand curve of your niche.
- Q1 (Jan-Mar): Post-Christmas hangover, focus on clearing out inventory and retaining stock. Therefore, the budget should be more restrained, focused on profitability.
- Q2 (Apr-Jun): Mother's Day and Valentine's Day. Increase the acquisition budget, it's time to bring new people into the base.
- Q3 (Jul-Sep): Preparation, focus on SEO and lead generation (at low cost) for Black Friday. Also, test new channels here.
- Q4 (Oct-Dec): or "all-in"Black Friday and Christmas. Probably 40% to 50% of your annual media budget will be spent here."
This way, you ensure you have resources to spend when the customer is most likely to buy, maximizing ROAS (Return on Advertising Spend).
6- Success Metrics: How to know if the Budget is Correct?
Finally, setting the budget is just the beginning. You need safety nets, so set up quarterly review triggers.
For example: “ If the ROAS from Google Ads falls below 5, we freeze the budget increase and review the campaign .” Or: “ If the Influencer channel brings in a CAC 20% lower than Google, we reallocate 5% of the budget there .”
The digital marketing budget for 2026 should be a living document . Rigidity breaks companies; adaptability makes them grow.
A SCENARIO AS AN EXAMPLE
To illustrate, let's imagine a fictional store in the fashion segment that grossed R$ 5 million in 2025 and wants to grow 20% in 2026 (target: R$ 6 million).
- Definition of %: In this case, they decide to invest 10% of their projected revenue in marketing. That is, a total of R$ 600.000,00.
- Division 70/20/10:
- BRL 420.000 (70%) Go to Google Shopping and Meta Ads (focus on conversion).
- BRL 120.000 (20%) goes to SEO, Pinterest Ads and Email Marketing (RD Station).
- BRL 60.000 (10%) goes to testing with live commerce e TikTok ads.
- Seasonality: They set aside R$ 250.000 of that total specifically for the months of November and December.
- TechnologyIn addition to the R$600k for media, they set aside R$100k annually for tools (VTEX, CRM) and agency fees.
Result: a clear plan, with defined goals and allocated funds for security and risk management.
CONCLUSION: MONEY FOLLOWS STRATEGY
In short, creating a digital marketing budget plan for 2026 requires a cold, hard approach to the numbers and a bold strategy. Don't fall into the trap of doing "more of the same."
Remember: traffic costs will rise and competition will increase. The only defense is intelligent resource allocation. Use the Zero-Based Planning method, respect seasonality, and reserve funds for testing new strategies. Those who plan ahead avoid market surprises.

Frequently Asked Questions about Digital Marketing Planning 2026
How much should I invest in digital marketing in 2026?
There's no magic number, but the average for the e-commerce market ranges from 5% to 15% of projected gross revenue. Stores in the rapid growth phase (scale-up) tend to invest more (closer to 15-20%) to gain market share, while mature stores focus on profitability (5-8%).
What should be included in the marketing budget?
The budget should cover three pillars: 1. Paid Media (the amount paid to Google, Meta, etc.); 2. Tools and Technology (CRM, e-commerce platform, automation); and 3. People and Services (salaries of the internal team, agency fees, content freelancers).
How do you adjust the budget if sales don't materialize?
That's why quarterly reviews are vital. If sales aren't happening, don't cut marketing immediately (that could kill the store). Instead, review efficiency (CAC and ROAS). In that case, it might be necessary to cut the "Innovation" budget (the 10%) and focus everything on "Performance" channels (the 70%) until cash flow stabilizes.
Is it worth investing in branding in 2026?
Yes, more than ever. After all, with paid traffic becoming more expensive, having a strong brand increases conversion and direct (free) traffic. We recommend that part of your "20%" expansion be focused on brand building and content, thinking long-term.
