The question of how much to spend on Instagram ads is a common one for businesses of all sizes. The truth is, there is no single right answer, but there is a right way to think about your budget. To start, most small businesses can begin testing with a daily budget as low as $5 per day, or a monthly budget of $300 to $500.
However, the ultimate amount you should spend is not a fixed number—it’s a figure directly tied to your specific business goals, your target audience, and the quality of your ad creative. Rather than asking “how much should I spend?”, the better question to ask is, “what do I want to achieve with my ads?”
It's Not About the Number, It's About the Goal
Your budget should be a direct reflection of your campaign’s objective. A campaign designed to build brand awareness has a very different budget requirement than one focused on driving 50 sales for a new product.
The Small Business Starting Budget:
For businesses just getting started, a test budget is essential. Meta (Instagram’s parent company) recommends a minimum of $5 per day to give the ad auction enough data to optimize your campaign. This low-risk approach allows you to experiment with different ad creatives and audiences without a major financial commitment.
As a general benchmark, many small to mid-sized businesses begin with a monthly budget between $300 and $500, which is enough to run meaningful tests and gather valuable insights.
The Goal-Oriented Budget Calculation:
For businesses with a clear revenue goal, you can calculate your budget using a simple formula. This method ties your ad spend directly to your desired business results.
Formula:

Example:
You want to get 20 new customers. Your website’s conversion rate is 2% (meaning 2 out of every 100 visitors buy). Your average Cost Per Click (CPC) is $1.
20 / 0.02 = 1,000
(You need 1,000 visitors)1,000 * $1 = $1,000
(Your required ad spend is $1,000)
Key Factors That Influence Your Spend:
The amount you actually pay will vary based on several key factors. Understanding these variables is the key to optimizing your budget and getting the most value for your money.
Audience Targeting & Competition:
Highly specific or niche audiences are often more expensive to reach because you’re competing with more advertisers for a smaller pool of users. Similarly, ads in competitive industries like finance, real estate, and fashion typically have higher costs.
Ad Quality and Relevance:
Instagram’s algorithm rewards high-quality, relevant ads with lower costs. If your ad has a high Relevance Score and a strong click-through rate (CTR), the platform will favor it, leading to a lower price in the ad auction.
Campaign Objective:
Your chosen objective tells the algorithm what you’re willing to pay for. Campaigns focused on “Sales” or “Conversions” will generally have a higher cost per result than “Brand Awareness” campaigns, because you are asking the algorithm to find users who are not just likely to see your ad, but to make a high-value purchase.
Seasonality:
Ad costs fluctuate throughout the year. Competition for ad space skyrockets during peak shopping seasons like Black Friday and the holiday season, leading to a significant increase in ad costs.
Actionable Tips for Smarter Spending:
Once you have a budget in mind, use these strategies to ensure every dollar is spent wisely.
Start with "Warm" Audiences:
Before you target new audiences, use a small budget to retarget people who have already engaged with your Instagram profile or visited your website. These audiences are much more likely to convert and will give you a better return on your initial investment.
A/B Test Your Creatives:
Don’t assume your first ad creative is the best. Run two or three variations with different images, videos, or headlines. The winning ad will likely have a lower cost per result and can be scaled up with more confidence.
Optimize for Quality:
Make sure your ad creative is visually stunning and directly addresses a pain point or desire of your audience. Focus on a clear and compelling call-to-action (CTA).
Don't Set It and Forget It:
Monitor your ad’s performance every few days. If you notice its performance declining, it might be a sign of “ad fatigue,” and it’s time to refresh your creative.
The Bottom Line:
How much you should spend on Instagram ads depends entirely on your business, but by approaching your budget with a clear strategy, you can avoid common pitfalls and achieve a positive return on your investment. Start small, test often, and let your business goals—not a fixed number—be your guide.
