Marketing Budget Calculator for Small Businesses

By Evoke Agency · Last updated October 30, 2026

A marketing budget calculator turns your revenue into a spending plan. The formula is annual revenue × the percentage you choose to invest, then ÷ 12 for a monthly budget. Many small businesses start around 7–8% of gross revenue, a guideline often attributed to the SBA, and adjust for their goals and margins.

Most small business owners we talk to around the Twin Cities either guess, copy what they spent last year, or spend whatever is left over at the end of the month. None of those is a plan. This free calculator gives you a starting number in about ten seconds: your budget per year, per month and per week, plus an example of how it could be split across Google Ads, SEO, social media, email, video and your website.

How do you use the marketing budget calculator?

1. Enter your annual revenue. Use last year's gross revenue (total sales before expenses). If you're newer or growing fast, use a realistic forecast for this year instead.
2. Pick a percentage of revenue. Type a number, drag the slider, or tap one of the three starting points: 5% to maintain, 8% for steady growth, or 12% if you're pushing hard into a new market, a new location or a new service.
3. Choose your type of business. This changes the example channel split, because a roofing company, a coffee shop and an accounting firm don't find customers the same way.
4. Read your results. You'll see the annual budget, what that means per month and per week, an example monthly split by channel, and a one-sentence summary of the numbers.

How is a marketing budget calculated?

Formula
Annual marketing budget = annual revenue × percentage of revenue
Monthly budget = annual budget ÷ 12
Weekly budget = annual budget ÷ 52
Each channel = monthly budget × that channel's share of the split

The percentage-of-revenue method is the most common way small businesses set a marketing budget because it scales with the business. When revenue grows, the budget grows with it. When a season is slow, you can see exactly what you're cutting.

How much should a small business spend on marketing?

A guideline you'll see cited a lot is that small businesses should spend about 7–8% of gross revenue on marketing and advertising. It's usually attributed to the U.S. Small Business Administration, and it's typically described as applying to businesses with under $5 million in sales. Treat it as a starting point, not a law.

Where you should land depends on a few things:

• Your goal. Holding steady with a full calendar of repeat customers needs less than breaking into a new city or launching a new service.
• Your margins. A business with thin margins has less room for paid ads. A business with healthy margins can often afford to spend more to win a customer.
• How established you are. A newer business with no reviews, no search rankings and no email list usually has to spend a bigger share of revenue to get noticed. An established business with strong word of mouth can often spend less.
• Your competition. If every competitor in your area is bidding on the same Google searches, standing out costs more.

If you want the longer version of this conversation, we wrote about it in how much a business should actually spend on marketing.

What does a small business marketing budget look like?

Say you own a home services company in the west metro doing $750,000 a year, and you want steady growth, so you pick 8%.

With "Local service" selected, the example monthly split looks like this:

That split is our opinion of a reasonable starting point for a local service business, where a lot of customers start with a Google search when they need someone now. It is not a benchmark. Your best split depends on where your customers actually come from, which is why tracking calls, forms and booked jobs matters so much.

How should you split a marketing budget by channel?

• Local service businesses (contractors, home services, clinics) tend to win on search: someone's furnace quits, they Google it, and they call whoever shows up with good reviews. That's why Google Ads and your Google Business Profile get the biggest slices.
• Retail, restaurants and e-commerce usually lean harder on social media, photos and video, and email or SMS, because people buy on impulse, return often and share what they like.
• B2B and professional services have longer sales cycles. Content, SEO, LinkedIn and email do more of the work of building trust before someone ever reaches out.

How should Minnesota businesses budget for the seasons?

Minnesota businesses have a calendar most marketing guides ignore. Landscapers, patio and deck builders, and outdoor venues get slammed from spring to fall and then go quiet. HVAC, snow removal and holiday retail flip the other way.

That doesn't mean spending the same amount every month. Set your annual budget with this calculator, then shift more of it into the months right before and during your busy season, and keep a smaller, steady presence in the off months so people still find you. We wrote more about that in marketing through the Minnesota slow season.

What mistakes should you avoid when setting a marketing budget?

• Only counting ad spend. Your budget should include the people and tools that make the ads work: design, video, website updates, email software, and agency or freelancer fees.
• Spreading too thin. $3,000 a month split across seven channels often does less than $3,000 focused on the two that bring you customers.
• Cutting first when things slow down. Marketing is often the first line cut, and the effect shows up months later as an empty pipeline.
• Not measuring. If you can't tell which channel brought in which customer, you can't move money to what works. Start with call tracking, form tracking and asking every new customer how they found you.

Frequently asked questions

How much should a small business spend on marketing?

A commonly cited guideline, often attributed to the SBA, is 7–8% of gross revenue for small businesses. Businesses that are new, entering a new market or launching a new service often spend more for a period of time; established businesses with strong referrals may spend less.

What is the formula for a marketing budget?

Multiply annual revenue by the percentage you want to invest in marketing. For example, $750,000 in revenue × 8% = $60,000 a year. Divide by 12 for a monthly budget ($5,000) or by 52 for a weekly budget (about $1,154).

How much should I spend on marketing per month?

Divide your annual marketing budget by 12. A business with $500,000 in revenue that invests 8% has a $40,000 yearly budget, which works out to about $3,333 a month.

Should my marketing budget be based on revenue or profit?

Most small businesses use gross revenue because it's simple and easy to track. If your margins are thin, sanity-check the number against profit too, so marketing doesn't eat the money you need to operate.

Does the marketing budget include agency fees?

It should. Count everything you spend to attract and keep customers: ad spend, agency or freelancer fees, software, design, photo and video, and website work.

How should I split my budget between Google Ads and social media?

It depends on how your customers buy. People searching for an urgent service usually find you on Google, while people discovering a restaurant or a product often find you on social media. Start with an example split, then move money toward whatever brings in actual customers.

How often should I revisit my marketing budget?

Set it once a year and review it every quarter. Check what each channel produced, and shift money toward what's working before your busy season starts.
