Quick answer: Google Ads calls lifetime budgets "campaign total budgets." Set a fixed amount, set dates, and Google paces spend automatically. You will never be charged beyond your total.

What Is a Lifetime Budget in Google Ads?
Google doesn't use the phrase "lifetime budget" in its interface. Know this before you go looking for it.
Google's 'Campaign Total Budget' Terminology
Per Google's Ads Help Center, the correct term is "campaign total budget." It works exactly how you'd expect a lifetime budget to work. Set a fixed dollar amount. Set a start and end date. Google spends that amount across the entire campaign window, no more.
How It Differs from Average Daily Budgets
Average daily budgets tell Google how much to spend per day on average. Google can spend up to 2x that amount on high-traffic days. It balances out over the month, capped at 30.4x your daily budget. Campaign total budgets work differently. There is no daily cap at all. Google controls daily pacing automatically to hit your total by the end date.
Fixed Spend Over a Defined Period
The core mechanic is simple. You commit to one number. Google owns the daily allocation. If early days underspend, Google adjusts remaining days upward. The total never exceeds what you entered.

Campaign Total Budget vs. Average Daily Budget
The right budget type depends on your campaign structure, not your spend level.
When to Choose Campaign Total Budget
Use a campaign total budget when you have a hard spend ceiling and a defined end date. Product launches, seasonal sales, and event-driven campaigns are perfect fits. You know the money. You know the window. Let Google optimize within it.
When to Choose Average Daily Budget
Use average daily budgets for always-on campaigns. No end date. Flexible monthly adjustments. You can pause, edit, and scale at any time. Campaign total budgets don't offer that kind of open-ended flexibility.
Spending Limits and Flexibility
One firm constraint: campaign total budgets are only available for new campaigns. Existing campaigns cannot switch from average daily budgets to total budgets. Plan this before you build.

Campaign Types and Duration Rules
Not every campaign type supports campaign total budgets. Check eligibility before you start.
Eligible Campaign Types
Per Google's Ads Help Center, campaign total budgets are available for five campaign types: Demand Gen, Search, Standard Shopping, Performance Max, and YouTube. Other campaign types do not support this feature.
Minimum and Maximum Duration Windows
Duration rules vary by type. For Search, Standard Shopping, and Performance Max: minimum 3 days, maximum 90 days. For Demand Gen and YouTube: minimum 7 days recommended, maximum 1 year. A 2-day Search campaign on a total budget is not possible. Plan your dates accordingly.
Date Selection Best Practices
Pick start and end dates that match your actual promotion window. Don't pad dates to gain extra impressions. A longer window with the same budget means less daily spend. Be precise. Tighter dates with concentrated spend often outperform loose, drawn-out flights.

How to Set a Lifetime Budget in Google Ads (Step-by-Step)
Access Campaign Creation
Open Google Ads. Click the Campaigns icon. Select "New campaign." Choose your campaign goal and type.
Select 'Campaign Total Budget' Option
In the Budget section, you will see two options. Select "Campaign total budget." This is where most people get stuck. The interface does not say "lifetime budget." Look for the total budget label specifically.
Enter Budget Amount and Dates
Enter your total budget amount. Set your campaign start date and your end date. These dates lock in your spending window. You cannot change the campaign type after launch, so double-check before proceeding.
Choose a Compatible Bid Strategy
Campaign total budgets work with all standard bid strategies: Target ROAS, Max Conversions, Target CPA, Max Conversion Value, Max Clicks, Target Impression Share, and Manual CPC. Smart Bidding is a strong choice here. It does not require a new learning period if you use account goal settings, so it starts optimizing immediately.
Verify Settings Before Launch
Review your total amount, start date, and end date carefully. Budget edits after a campaign launches can disrupt Google's pacing model and affect overspend credit calculations. Get it right the first time.

Campaign Total Budget Best Practices
Minimize Budget Edits During Flight
Changing your budget mid-campaign disrupts Google's pacing. Make edits only when absolutely necessary. Any change resets overspend credit calculations based on the new amount going forward.
Reduce Campaign Overlap
Running multiple campaigns targeting the same audience and dates splits your budget in unpredictable ways. Consolidate overlapping campaigns where possible. Clean structure produces cleaner results.
Choose the Right Bid Strategy
Smart Bidding reads your total budget and paces bids to maximize outcomes across the flight. Manual CPC works too but demands closer daily monitoring. For most total-budget campaigns, automated bidding is the better match.
Understand Pacing and Overspending Protections
Google uses standard delivery only with campaign total budgets. No accelerated delivery option exists. You won't blow your budget on day one. Google Ads documentation confirms you will never be charged beyond your total, even if the platform serves more traffic than expected.

Key Guarantees and Limits
Never Charged Beyond Total Budget
This is a hard guarantee. Per Google's Ads Help Center, you will never be charged more than your campaign total budget amount, full stop.
Standard Delivery, Not Accelerated
Budget paces evenly across your flight. Google decides the daily allocation. You don't set daily amounts.
No Daily Spending Caps
There are no per-day limits with campaign total budgets. Google optimizes daily pace to maximize performance across your full window.
Learning Period Handling
Campaign total budgets don't require a new learning period when you use account goal settings. Smart Bidding continues learning across all conversion actions without a restart.

Why Lifetime Budgets Work for Specific Campaigns
Limited-Time Promotional Campaigns
Black Friday. Back-to-school. End-of-quarter clearance. These campaigns have hard stop dates. Campaign total budgets enforce the spend ceiling automatically.
Event-Driven Spending
Product launches and brand events need concentrated spend in a narrow window. Total budgets give you that control without daily check-ins.
Fixed Marketing Budgets
Finance approved $5,000 for a campaign. Not a dollar more. Campaign total budgets enforce that ceiling without manual pausing or monitoring.
Predictable Spend Planning
No surprise overspend. No emergency pauses. You set the number. Google respects it. Reporting stays clean and matches your plan.
