UA scaling calculator
Plan an iOS and Android UA budget ramp by week. Enter starting budgets, platform-specific growth rates, and checkpoint thresholds to see weekly totals, cumulative spend, and when the ramp becomes operationally meaningful.
Campaign inputs
Use your own budgets and growth assumptions. The defaults are illustrative, not benchmark recommendations.

Budget QA
What to check before you scale
The calculator is meant to catch budget surprises before a campaign ramp reaches finance, creative, or channel teams. Use it to pressure-test the pacing, not to justify spend after the fact.
Will Q2 get too steep?
Weekly increases compound quickly. Compare weeks 1-13 against weeks 14-26 before you commit to the ramp.
Is iOS carrying the risk?
Keep iOS and Android separate so the platform split stays visible as weekly spend compounds.
When do spend checkpoints hit?
Use the milestone notes to see when daily spend levels become operationally meaningful.
Where does pacing break?
Scan every week in the table so the jump from planning to execution is visible before launch.
How it works
Enter week 1 spend
Start with separate weekly budgets for iOS and Android campaigns.

Choose the weekly compounding increase used for both platform budgets.
Review the ramp
Use the quarterly totals and weekly table to pressure-test the plan before committing budget.
How to plan a user acquisition spend ramp
A UA spend ramp is the weekly budget path you expect to follow as campaigns move from launch to scale. It should be specific enough for finance and campaign operators to review, but flexible enough to change when returns, pacing, or operational capacity move.
The key is separating the plan by platform. iOS and Android often scale differently, and a blended total can hide where the ramp is actually coming from. Keeping both columns visible makes the budget conversation clearer.
What should a UA scaling calculator include?
A useful UA scaling calculator should show weekly spend, cumulative spend, platform split, growth assumptions, and checkpoint notes. Quarterly totals matter because budget approvals are often reviewed by month or quarter, while campaign changes happen weekly. The calculator bridges those planning cadences.
Use the output as a starting forecast, not a promise. If early return data is weaker than expected, slow the growth rate. If the ramp is holding, you can increase spend with a clearer view of the cash requirement.
Why weekly growth rates matter
Weekly growth rates compound quickly. A campaign that starts at $10,000 per week and grows 8% weekly is not just adding $800 every week; the increase compounds on the prior week’s budget. That creates a much steeper second quarter than many teams expect when they first sketch a ramp.
This is why quarterly totals are useful. They show the real budget commitment created by a weekly scaling assumption. A plan may look conservative in week one and aggressive by week twenty-six.
How to use checkpoints in a spend forecast
Spend checkpoints make the ramp easier to evaluate. A weekly total may look abstract, but translating it into approximate daily spend helps teams understand when creative volume, channel coverage, and measurement discipline need to increase.
Once campaigns are live, compare actual weekly spend against the plan. This helps you see whether variance is coming from pacing, platform mix, or a deliberate change in scaling confidence.
Frequently asked questions
What is a UA scaling calculator?
A UA scaling calculator forecasts user acquisition budget over time. This one projects iOS and Android spend separately, applies platform-specific weekly growth rates, and shows weekly plus cumulative spend.
Why does the calculator use weekly growth?
Most paid social scaling decisions happen weekly. Weekly growth rates make it easier to plan campaign pacing, budget approvals, and creative production needs.
Should iOS and Android use the same growth rate?
Not necessarily. Some teams use one shared growth rate to keep the platform split constant. Others use separate iOS and Android growth rates when one side is expected to scale faster.
