Facebook Ad Billing

MailChimp’s new Ad Builder helps you build, submit, and pay for a Facebook adīš˜all in one place. No matter what MailChimp billing plan you’re on, you can purchase an affordable ad campaign to target people on Facebook. Ads start as low as $5 per day, and MailChimp doesn’t charge you any extra fees.

In this article, you’ll learn about the billing process for our Facebook ad campaigns.


  • Facebook ad campaign
    A pay-per-click Facebook ad created and purchased through MailChimp.

  • Total budget
    The maximum amount of money that you want to pay to run your ad on Facebook. Facebook sets a minimum budget of $5 (USD) per day.

  • Amount spent
    The amount of money that was actually used from your total budget, based on how many people clicked your ad.

  • Ad credit
    The amount we refund if you have leftover budget after ad completion (total budget minus final amount spent). You can use these credits to run your ad again, or buy a new ad.

How Pricing Works

So, how much does a Facebook ad cost? The budget depends on the audience size and the length of your ad’s run on Facebook. MailChimp's Ad Builder will help recommend a budget that feels right for you. You can spend a few dollars, or much more. It’s totally up to you, so you may want to start small to experiment.

We provide Facebook ads at cost, which means you buy the Facebook ad from us instead of Facebook, but we don’t charge any extra service fees. We rely on Facebook’s automatic bidding for ad price determination. The price of their ads can fluctuate daily, depending on the demand for ads, the audience you choose, and other factors.

Not to worry, though, because we’ll never spend more than the total budget that you set in the Ad Builder. And your credit or debit card won’t be charged until you actually confirm your ad, so feel free to experiment with different audiences and timelines in our Ad Builder to see what your budget could be.

Budget vs Amount Spent

In MailChimp's Ad Builder, you’ll set your budget, which is the maximum amount you want to pay, and then submit your ad to Facebook. After submission, we’ll charge you the total budget amount.

When the ad is done, we’ll deduct the ad’s actual cost from your total budget based on the number of clicks the ad received. This means you’ll only be charged for each person who clicks your ad on Facebook. Sometimes, the amount spent may be slightly less than your initial budget.

It takes about 72 hours after your ad is complete for us to calculate the final amount spent. If you end up with some extra budget left over, we’ll store it in your MailChimp account, so you can use it to run the ad again, or buy a new one.

View Your Ad Credits

If you have some extra ad budget left over, or if your ad was paused or canceled early, we’ll refund you with ad credits. Available ad credits are delivered to your account 72 hours after your ad’s scheduled end date. 

To view your ad credit balance, follow these steps.

  1. Click your profile name and choose Account.

MailChimp will automatically apply any available ad credits to the budget of your next ad campaign. Ad credits can only be used for the purchase of ad campaigns.

Credits for Ad Rejections

Sometimes, Facebook may reject certain ads that don’t fit their content standards. If this happens, we’ll make sure your account gets credited with a refund. You can use the refunded ad credit to edit and resubmit your ad at no additional cost, or spend the credit on a new ad. If you don't resubmit the ad, you'll automatically receive the ad credit when your ad reaches the scheduled completion date.  Read more about ad rejections and resolution in our article, Facebook Ad Submission Errors.
