Most small businesses should spend 5–10% of gross monthly revenue on digital marketing. Businesses with less than $500K in annual revenue typically invest $500–$2,000/month. Those earning $500K–$2M invest $2,000–$5,000/month. New businesses and startups should spend on the higher end up to 15–20% to build early market presence. The exact small business digital marketing budget depends on your growth goals, industry competition, and which channels you prioritize. Across every channel, the most important rule is this: fund a few channels properly rather than spreading a small budget across everything.
If you have ever typed “how much should a small business spend on digital marketing” into Google and gotten fifteen different answers ranging from $200 to $20,000 a month, you are not alone. The honest answer is that there is no single right number but there is a right framework for finding your number, and that framework is what this guide is built around.
For small businesses across central Ohio including the business customers of Richwood Bank who work with Richwood Marketing’s digital marketing services we see this question come up in almost every first conversation. Business owners want to grow, but they want to spend intelligently, not just throw money at channels that sound impressive and hope something sticks.
By the end of this post, you will know the benchmarks, the channel-by-channel breakdown, the common mistakes that waste budget, and exactly how to calculate a monthly digital marketing budget that makes sense for your specific business.
What Percentage of Revenue Should a Small Business Spend on Marketing?
The most widely cited benchmark for how much to spend on digital marketing comes from the U.S. Small Business Administration: businesses with revenues under $5 million should allocate 7–8% of gross revenue to marketing. Survey puts the average marketing budget at 7.7% of company revenue, while the Deloitte and Duke CMO Survey puts it at 9.4%.
Here is what those percentages look like in real dollar terms:
| Annual Revenue | Recommended % | Monthly Marketing Budget |
| Under $250K | 10–15% | $2,100–$3,100/month |
| $250K–$500K | 7–10% | $1,460–$4,160/month |
| $500K–$1M | 7–10% | $2,900–$8,330/month |
| $1M–$2M | 5–8% | $4,170–$13,330/month |
| $2M–$5M | 5–7% | $8,330–$29,160/month |
Small businesses with revenues under $10 million typically allocate 15.6% of their budget to marketing, notably higher than the enterprise average, because they are still building brand awareness from scratch.
Important caveat: These percentages are starting points, not rules. Your profit margins set the ceiling. A business running on 10% margins cannot afford to spend 10% on marketing. You need to know your actual numbers before committing to a budget.
What Is a Good Digital Marketing Budget for a Small Business? Realistic Ranges by Stage
Rather than percentages alone, it helps to understand what digital marketing costs for small businesses look like at different growth stages:
Early-stage businesses (under $500K revenue): $500 to $2,000 per month on average, around $1,200 typically. Most businesses at this level are doing basic local SEO, maybe running a small Google Ads campaign, and managing their own social media.
Growth-stage businesses ($500K–$2M revenue): $2,000–$5,000 per month. This range funds a proper SEO strategy, managed Google Ads with real optimization, and consistent content. A minimum of around $3,000 per month will produce sustainable growth over time if invested wisely into marketing.
Established businesses ($2M+ revenue): $5,000–$15,000+ per month. At this level, you should have clear cost-per-lead data and be allocating budget based on proven channel performance.
Startups with no existing customer base: Early-stage companies generally spend on the higher end 10–20% to build awareness and test channels.
How to Split a Digital Marketing Budget: Channel-by-Channel Breakdown
Once you have your total monthly budget, the next question is how to split a marketing budget across channels. Here is what the data and our direct experience with central Ohio small businesses suggest:
SEO Marketing Budget
SEO ranges from $500 to $5,000 monthly for small businesses, with most agencies charging under $1,000/month. For local businesses in Ohio markets Marysville, Bellefontaine, Delaware, Marion a focused local SEO budget of $800–$2,000/month is typically enough to compete effectively in the map pack and organic results.
Recommended allocation: 25–35% of total digital marketing budget.
Google Ads Budget (PPC Advertising)
PPC advertising costs $1,500 to $15,000 monthly for small businesses. For local service businesses, a $500–$2,000/month Google Ads budget can generate meaningful leads when the campaign is properly structured with tight geo-targeting, negative keywords, and conversion tracking.
Recommended allocation: 30–40% of total budget.
Social Media Marketing Costs
Social media marketing runs $750 to $7,000 monthly for full management. For most Ohio small businesses, a combination of organic posting ($300–$800/month for managed content) and paid social advertising ($300–$1,000/month in ad spend) is the right starting point.
Recommended allocation: 15–25% of total budget.
Content Marketing Budget
Blog writing, service page optimization, and email marketing content typically run $500–$2,000/month for small businesses depending on volume. Marketers on average allocate 8% of their marketing budget to email marketing, one of the highest-ROI channels available.
Recommended allocation: 10–20% of total budget.
Website Marketing Costs
An ongoing website investment maintenance, conversion rate optimization, and landing page development for campaigns runs $150–$500/month for most small businesses once the initial build is complete.
Recommended allocation: 5–10% of total budget.
Budget Allocation by Business Type: B2B vs B2C
Your business model significantly affects the right digital marketing spending strategy:
B2B companies should spend between 2% and 5% of revenue on marketing, while B2C companies typically need 5–10% because they must invest in more marketing channels to reach various customer segments.
For service businesses, the most common type among Richwood Bank’s business customers across central Ohio, the right approach usually prioritizes local SEO and Google Ads together, with content supporting both. A service business in Richwood or Plain City competing for local customers does not need a national content strategy; it needs hyper-targeted local visibility.
The 70-20-10 Rule: A Framework for Allocating Your Marketing Budget
Rather than guessing, use the 70-20-10 framework as a useful starting point: 70% to proven high-ROI activities, 20% to promising growth opportunities, and 10% to experimental initiatives.
In practice for a central Ohio small business spending $2,000/month:
- $1,400 (70%) → Local SEO + Google Ads (proven lead generators).
- $400 (20%) → Content marketing + email (building long-term organic presence).
- $200 (10%) → Testing a new social platform or new ad format.
This framework prevents both under-investing in what works and over-investing in untested ideas.
How to Calculate Your Digital Marketing Budget: Working Backwards From Revenue Goals
The most effective way to answer “how much should I spend on digital marketing” is not to start with a percentage it is to start with your revenue goal.
Step 1: Set your monthly revenue goal.
Step 2: Determine how many new customers you need to hit it.
Step 3: Calculate your acceptable cost per customer acquisition (CPA).
Step 4: Multiply: CPA × new customers needed = minimum monthly marketing budget.
Example:
- Revenue goal: $20,000/month above current
- Average customer value: $500
- New customers needed: 40
- Acceptable CPA: $80
- Minimum monthly budget: $80 × 40 = $3,200/month
This approach ties marketing spend directly to business outcomes, rather than picking an arbitrary percentage.
Common Digital Marketing Budget Mistakes Ohio Small Businesses Make
After working with dozens of businesses across Union, Logan, Delaware, and Morrow counties, these are the budget mistakes we see most often:
Spreading too thin: Putting $200 into SEO, $200 into Google Ads, $200 into Facebook, and $200 into email means nothing gets enough fuel to work. Pick two channels and fund them properly. You can expand later.
Spending without tracking: Running Google Ads without conversion tracking is like driving with your eyes closed. Every dollar spent should be attributed to a specific lead, call, or form submission.
Skipping the foundation: Starting with paid ads before fixing your website is the single most common budget-wasting mistake. If your site does not convert visitors, more traffic just means more wasted spend.
Treating marketing as a cost rather than an investment: 94% of businesses report being satisfied with their digital marketing ROI when campaigns are properly set up and managed. The budget question shifts from “how much can we afford to spend?” to “how much can we afford not to spend?”
Is Digital Marketing Worth the Cost for Ohio Small Businesses?
Short answer: yes when the budget is allocated strategically and the work is executed correctly. Nearly half 49% of small businesses plan to increase their marketing budgets in 2025, while only 16% plan to decrease them. That signal tells you something important: the businesses that have tried digital marketing and measured it honestly are doubling down, not pulling back.
For Richwood Bank business customers across central Ohio, the advantage is access to a marketing team already embedded in the communities they serve one that knows what local SEO costs in Marion versus Marysville, what Google Ads CPCs look like for home services in Union County, and what content performs in these specific markets.

At Richwood Marketing, we do not recommend a budget until we understand your revenue, your margins, your growth goals, and your competitive landscape.
