Lower your CPI with better creative

Reverze rebuilds App Store screenshots into higher-converting creative

Plan your app marketing budget with confidence

Every paid user acquisition plan starts with two numbers: how many installs you want and what each one costs. This app marketing budget calculator turns those two inputs into a clear budget and a daily spend, so you can size a campaign before you commit a single dollar.

The math is simple, but the leverage is not. Your cost per install is driven largely by how well your store creative converts. Sharper screenshots and headlines lift tap-through and conversion, which lowers your CPI β€” and a lower CPI means the same install goal costs a smaller budget. Improving creative is often the cheapest way to stretch your user acquisition budget.

Frequently asked questions

How is my app marketing budget calculated?
Budget equals your target installs multiplied by your cost per install (CPI). For example, 10,000 installs at a $2 CPI is a $20,000 budget.
What is a good cost per install (CPI)?
CPI varies widely by category, geography, and platform β€” often from under $1 to well over $5. Use your own campaign data when you have it, and treat public benchmarks only as a starting point.
How can I lower my CPI?
Improve your store creative. Higher-converting screenshots and headlines raise your conversion rate, which lowers your effective CPI and shrinks the budget needed for the same number of installs.
Why divide the budget across 30 days?
Most paid campaigns run monthly, so a 30-day daily budget gives you a realistic pacing target and makes it easy to compare spend against your other channels.
