Apple Search Ads Budget Planner

Apple Search Ads has a short, measurable funnel: impressions → taps → installs. Tap-through rate connects the first two stages and conversion rate connects the last two, so any install goal implies a specific number of taps (installs ÷ CVR) and impressions (taps ÷ TTR). Multiply required taps by your average CPT and you have the true cost of the goal. If 1,000 installs at 50% CVR and $1.50 CPT implies $3,000, no amount of budget-setting optimism changes that.

The same math exposes your levers. Doubling budget doubles installs only if CPT holds — on a small keyword set, extra budget just exhausts the available impressions and inflates CPT as you chase the remaining auctions. Improving CVR (better screenshots, a custom product page matched to the keyword theme) or trimming CPT (tighter bids, negatives) lowers the cost of the same goal without spending more.

Apple Search Ads campaigns use a daily budget, and Apple may spend up to a modest overage on strong days while keeping the monthly total in line with daily budget × days in the month. Dividing your monthly figure by ~30.4 gives the baseline daily number, but watch the first week closely: a campaign that exhausts its budget by mid-day is telling you demand exceeds your cap, which means you are ceding late-day auctions — often at times when competitors have also capped out and CPT is cheapest.

Do not spread budget evenly across campaigns either. Brand campaigns need enough to never cap out (losing a brand auction hands your own customer to a competitor), discovery campaigns need a fixed exploration allowance you treat as research cost, and generic campaigns should receive whatever remains, weighted toward the keyword themes with the best CPA. Revisit the split monthly as data accumulates.
