How much to spend on your first Facebook and Instagram ads
There's no right amount for everyone. The best starting budget is one you can afford to lose and that's enough to generate data. Never use bill money or a loan to test ads.
1. Work out what you can pay per sale
Start with your profit before ads: price minus costs, fees and shipping.
Made-up example: a $30 product with $12 in costs leaves $18. If you pay more than $18 in ads per sale, you lose money.
2. Work out your testing budget
A common rule of thumb is to set aside 2 to 3 times that maximum for each test. In the example, that's $36 to $54. It's not a Meta rule, just a way to get some data before deciding.
3. Spread it out
Meta's system goes through a learning phase, and big changes can restart it. A low daily budget for several days beats spending everything in one day.
4. Decide with numbers
- Pause if spend passed your limit with no sales and clicks are weak.
- Fix the page if you get lots of clicks and few sales.
- Scale gradually if your cost per sale is below your limit.
Spend less by missing less
