What is an Ad Budget Calculator?
An ad budget calculator helps you forecast the impact of budget changes on your advertising campaigns. Unlike simple calculators that just compute metrics, our budget calculator models the realistic effects of scaling your spend up or down, including diminishing returns and efficiency changes.
Why Use a Budget Calculator?
- Budget Planning: Prepare accurate forecasts for quarterly or annual budget proposals
- Scaling Decisions: Understand the real impact of doubling or tripling your ad spend
- Efficiency Analysis: See how CPA and ROAS change at different budget levels
- Risk Assessment: View best and worst case scenarios before committing to budget changes
Budget Scaling Effects
When you increase your advertising budget, you typically experience diminishing returns. This means:
- First $1,000 might get you 100 conversions (CPA: $10)
- Second $1,000 might get you 80 more conversions (CPA: $12.50)
- Third $1,000 might get you 60 more conversions (CPA: $16.67)
Our budget calculator models these diminishing returns so you can make informed decisions about scaling.
