Daily Budget vs. Lifetime Budget: Which One to Use?
Meta offers two budget types. A daily budget tells the system the maximum it can spend each day — Meta may slightly exceed or fall short of this to catch better opportunities. A lifetime budget caps total spend for the entire campaign duration. For always-on campaigns, a daily budget is more flexible; for a specific event or seasonal push, a lifetime budget gives more predictable control.
The Most Reliable Way to Calculate Your Starting Budget
Start by asking: 'How much profit does a single customer bring me on average?' For a dentist, that might be the margin on a filling or implant; for a boutique, the average sale value during a season. Once you know this number, estimate how many people you need to reach to win one customer. According to Meta, a small percentage of users who see an ad take a meaningful action — the exact rate depends on your industry, offer, and creative quality. Your budget needs to cover that acquisition cost and still leave room for profit.
Meta's own guidelines recommend setting your daily budget at least 5 times your target cost per result so the ad set can complete its learning phase properly. For example, if you aim to acquire a customer for 200 TL, a daily budget around 1,000 TL gives the system enough data to optimize.
- Start small: the first weeks are a test budget, not a profit budget. You are teaching the system what works for your business.
- Do not disrupt the learning phase: Meta's system spends the first 7-10 days learning. Frequent budget changes during this window reset the learning and slow down optimization.
- Shift budget toward winners: whichever ad set delivers results at a lower cost gets more budget; pause or reduce the rest.
- For campaigns using Advantage+ (Meta's AI ad system), setting the budget at the campaign level lets the system distribute spend more efficiently across audiences.
- Account for seasonality: competition and click costs rise during holidays, back-to-school, and peak seasons — increase your budget ahead of time.
- Match budget to objective: a budget aimed at likes or followers works very differently from one targeting sales or lead form submissions.
