How to Set an Ad Campaign Budget You Can Actually Learn From
By Adsonmarket Editorial Team ·
A budget too small teaches you nothing; one too big burns money before you know what works. The goal of a first budget is not profit — it is enough data to make the second decision.
Start from the result you need
Decide how many conversions you need to judge a campaign — 30 to 50 is a reasonable minimum.
Daily vs total budget
A daily cap smooths delivery; a total cap protects you from overspending.
Daily budget
Total budget ÷ number of test days.
Total budget
Target conversions × expected cost per conversion.
Leave room to test
Reserve 20% of the budget for a second creative or audience after the first week.
Example
A $300 test
An app expects $6 per install and wants 40 installs: 40 × $6 = $240, plus 20% reserve ≈ $300 total. Over 10 days that is a $30 daily budget.
Step-by-step
- Choose a conversion goal
- Estimate cost per conversion
- Multiply by 40 for total budget
- Divide by test days for daily budget
- Review after half the budget is spent
