How to Set a PPC Budget Cap | Don’t Overspend on Amazon Ads

Running Amazon ads can feel like trying to control a firehose—powerful, but with the potential to get out of hand quickly. A single misconfigured campaign or an unexpected surge in traffic could drain your budget before you’ve even had your morning coffee. Fortunately, Amazon provides powerful, built-in tools to put you back in control. By implementing a few key strategies directly within your Campaign Manager, you can create a financial safety net, prevent runaway spending, and allocate your ad dollars with precision.

Here are two essential methods for mastering your Amazon advertising spend.

1. Set an Account-Level Daily Budget Cap

Think of this as your ultimate emergency brake. The account-level daily budget cap is a global setting that prevents your total spend across all Sponsored Product campaigns from exceeding a specific amount on any given day. It’s the most straightforward way to ensure you never face a shocking advertising bill due to an oversight or error.

This setting acts as a hard stop. Once your combined campaign spending hits this predefined daily limit, Amazon will pause all your ads for the remainder of the day. They will automatically resume the following day. This provides invaluable peace of mind, especially for sellers managing numerous campaigns simultaneously.

It’s critical, however, to understand how this differs from an individual campaign’s budget. A single campaign’s “average daily budget” is managed over a full month. This means Amazon might spend more than your set daily amount on high-traffic days (sometimes up to 100% more) by using unspent budget from slower days. While your total monthly charge won’t exceed your daily budget multiplied by the days in the month, your daily spend can fluctuate significantly. The account-level cap overrides this fluctuation. If your campaigns collectively hit that master limit, everything stops, protecting you from those unexpectedly high-spend days.

2. Leverage Portfolios for Granular Control

If the account-level cap is your emergency brake, portfolios are your power steering. Portfolios allow you to group related campaigns together—for example, by brand, product line, or seasonal promotion—and manage their budgets collectively. This is where real strategic budget allocation happens, a process that can be streamlined with tools like Helium 10.

Instead of just setting a single cap for your entire account, portfolios let you create distinct budget pools for different business objectives. When you place campaigns into a portfolio, you unlock more sophisticated budget controls that apply to the entire group.

You can set a portfolio budget in a few key ways:

  • Date Range Budget Cap: This is perfect for short-term initiatives. Launching a new product or running a promotion for Black Friday? Set a total budget for that specific date range. Once the campaigns within the portfolio collectively spend that amount, they will all pause, ensuring your event stays perfectly on budget.
  • Recurring Monthly Budget Cap: This is the ideal tool for ongoing budget management. You can assign a fixed budget to a portfolio that resets on the first of every month. For instance, you can allocate a specific monthly budget to your top-selling product line and a separate, smaller budget to a newer brand you’re testing. This ensures no single product category eats into the ad spend designated for another, giving you precise control over your monthly advertising plan.

While these built-in tools offer significant control, many top sellers find that partnering with a specialized agency like EHP Consulting Group is the key to maximizing their ROI.
