Limited by budget with a target CPA or target ROAS

Updated

What the status means

“Limited by budget” is a status Google Ads shows on a campaign. Google’s help says it means your average daily budget is lower than what’s needed to capture all the clicks and impressions your settings make possible.

In plain terms, there are more searches you could show up for than your budget can pay for. So Google shows your ads less often.

This page is about one specific case. The campaign is limited by budget and also uses a target. That’s either:

  • Target CPA: a goal for your cost per acquisition (what you want to pay for each lead or sale).
  • Target ROAS: a goal for return on ad spend (how much revenue you want back for each dollar spent).

Why your cost per lead can rise

In the past, a budget-limited campaign with a target could do better than its target. If your target CPA was $50, you might actually pay $35. The budget held the campaign back, so it only bought the cheapest clicks.

Google changed this. Starting August 17, 2026, Google updated how target-based bidding works for campaigns that are limited by budget. Google says the rollout finished on August 27, 2026. Campaigns now aim more closely at the target you set, instead of beating it.

Google gives an example. A campaign with a $10 target CPA that was getting $5 conversions now delivers closer to a $10 cost per conversion.

So if you set a target long ago and forgot about it, your cost per lead may have gone up. Nothing broke. The system is now doing what your target told it to.

The change applies to target CPA and target ROAS in Search, Shopping, Performance Max, Demand Gen, Display, Hotel and Travel campaigns. Google says it won’t change your budgets or targets for you.

Why it matters for your money

Your target is a promise you make to Google about what you’re willing to pay. If your target says $50 per lead but you really want $35, Google may now spend up to that $50 level.

For a small business, that difference adds up fast. The same budget may now buy fewer leads.

How to check your account

  1. Open Campaigns and look at the Status column. Find campaigns that say “Limited by budget.” (If you can’t find it, search for “campaigns” in the Google Ads search bar.)
  2. For each one, check the bid strategy. Is it target CPA, target ROAS, or Maximize conversions or conversion value with a target set?
  3. Note the target. Then compare it with your actual cost per conversion over the last few weeks.
  4. Compare the last 28 days with the 28 days before. Did cost per conversion go up?

How to decide what to do

Start by asking: “Is my target the number I actually want?”

If your target is higher than you’d really pay: lower the target closer to the cost you were getting before, or to what you can afford. Google’s help suggests updating targets to match recent performance if you want to keep it. A tighter target will likely mean less daily spend and possibly fewer conversions.

If your target is right and you want more volume: consider raising the budget. Google suggests giving as much budget room as you can while a campaign is limited by budget. It also notes the higher budget may not be spent in full. Check the Recommendations page and the budget simulator in the campaigns table for estimates first.

If you want volume and don’t mind cost moving around: Google lists switching to Maximize conversions or Maximize conversion value without a target as an option. Expect cost per conversion to vary as budgets change.

For ROAS, the logic flips. A higher target ROAS asks for more return per dollar, which is stricter.

Whatever you change, make one change at a time. Google suggests waiting one to two conversion cycles (the usual time from click to sale for your business) before judging results.

When it’s fine

“Limited by budget” alone is not a problem. Many small businesses have more possible searches than money. If your cost per lead is where you want it, there’s nothing to fix.

It’s also fine if cost per conversion rose a little and is still well inside your goal. The goal is not the lowest number possible. It’s a number that makes you money.

SpendCanary flags budget-limited campaigns with a CPA or ROAS target whose cost per conversion in the last 28 days is at least 25% higher than in the 28 days before.
