An SEO budget is the amount of money a business spends each month on search engine optimization, the work that helps your website show up when people search on Google. It covers fixes to your site, content, links and local listings, and now visibility in AI search tools. This free SEO budget calculator runs in your browser with no signup and no limit. It returns a monthly range with three levels, lean, typical and aggressive, and a split of where the money goes.
How to use the SEO budget calculator
The calculator asks for five inputs. Enter them in this order.
- Business type. Choose the industry that best matches your business. The sector affects how much competition you face.
- Market. Choose the area you want customers from, from one town up to nationwide. Local work and multi-city or national campaigns cost different amounts, so pick the true size of your market.
- Competition. Rate how competitive your market is. Industry competition, the number of target keywords, the amount of content needed, the technical work required and any local or international targeting all change the price.
- Work needed. Tick the work you need: technical fixes, content, digital PR, local SEO or AI search visibility. Adding AI search visibility adds about 15 percent. To see where your business stands in AI search first, try the AI visibility checker.
- Revenue (optional). Add your monthly revenue and the calculator shows the budget as a share of it.
Many people use calculators like this incorrectly when they treat the budget as a forecast of return on investment. The result is a starting range for planning. The final price also reflects the hours, tools and services a provider uses, so compare the range with what you buy.
How much does SEO cost?
The cost depends on how much work your site needs, which services you buy, and how many places you serve, such as one town, a region or the whole country. Projects with more services, more locations or more pages cost more, and so does a market with heavy competition. Build the price from each part, then compare the total with any headline number.
What do SEO services typically include?
SEO usually bundles technical work, content, link building and local SEO. Each one adds cost. Ask an agency to show each service on its own line before you sign.
How does the state of your website change the cost?
Website condition raises the cost. Technical issues, thin content, broken links and a history of bad SEO practices need fixing before new work can grow traffic. Budget for that repair work in the first months.
What does a monthly SEO retainer cost?
In Ahrefs' pricing survey of 439 SEO providers, the most common monthly retainer was $501 to $1,000. Agencies averaged about $3,200 a month and freelancers about $1,350. Most small local businesses spend between $500 and $2,000 a month, and national campaigns cost several times that. Use these as reference points for comparing quotes, not as a price list.
Why is very cheap link building a risk?
Linking schemes are the risky shortcut in link building. Low-cost services often use black-hat tactics, which risk penalties from Google. Ask the provider exactly how links will be earned before you agree to pay.
What about promised rankings?
No provider can honestly promise a ranking, and some agencies still advertise results they cannot control. Treat any such promise as a warning sign and check the scope in writing.
What are SEO pricing models, and which should you choose?
Agencies price SEO in one of three ways: a monthly retainer, a fixed-price contract or a project fee. Each suits a different kind of business, and the right one depends on how clearly you can define the work.
Which pricing model suits a small business?
Project-based pricing lets you pay for custom SEO projects that focus on particular needs, such as a site rebuild or a set of landing pages. Fixed-price contracts set one total for a defined scope. Monthly retainers spread the work over time. Check which model a quote uses before you compare the numbers. My pick for most small businesses is a monthly plan with a written list of tasks and a three-month review. I would switch to a fixed project only when the job is a single, clearly defined fix.
How should you read an SEO pricing guide?
A pricing guide helps you check a quote against a typical range, so you can spot one far outside it. Use it to check each quote's scope before you check its price.
A contributor to Entrepreneur's leadership network writes that under about 1,000 dollars a month, you are mostly buying a few hours of work.
Is SEO a long-term commitment, and is it right for you?
SEO is a long-term commitment, and you should expect a slow start.
An Entrepreneur contributor advises a contract of at least six months, since the early months are mostly groundwork. In an Ahrefs study of 1 million random URLs crawled in September 2023, only 1.74 percent of newly published pages reached the top 10 within a year. The same study found that 72.9 percent of top 10 pages are more than three years old, so a new site competes with established pages. SEO needs ongoing investment to keep rankings in place, so it suits a business that can wait for results and keep paying for upkeep. To see when a budget would pay for itself, use the SEO ROI calculator.
How do you develop a realistic SEO budget?
Start from the work your site needs, then price each part, then add a line for AI search visibility if you want it. The calculator above does this in five inputs.
The order to build it in
Work through the budget in this order. First, list the work: technical fixes, content, digital PR, local SEO and, if you want it, AI search visibility. Second, set a monthly figure for each line. Third, check the total against your revenue. Keep the foundations, such as technical SEO, on-page work and links, funded before you add anything new.
A 2026 survey of 300 US enterprise leaders, published by a marketing platform, found that 65 percent put at least 25 percent of their 2026 marketing budget into AI search optimization. That survey covers firms with 500 or more staff, so a smaller business should not copy the share without testing it against its own revenue.
How should you adjust an SEO budget for AI search?
Keep the foundations funded: technical health, content and links. Then move a share of the budget, often 10 to 20 percent, to AI search work. That means making your site readable to AI crawlers, writing answer-first content, adding structured data and earning mentions on the sites AI engines cite. The calculator adds about 15 percent when you tick AI search visibility, and shows the split.
