UPLIFY commercial fit: UPLIFY advertising management starts at $320/month for the basic package with ad spend up to UAH 50,000/month. The team’s management fee is not included in this calculator’s advertising budget; ad spend is paid separately.
Formula: purchase CPA × target purchases × (1 + buffer). Average daily budget = monthly plan ÷ 30.4.
Formula: purchase CPA × target purchases × (1 + buffer). Average daily budget = monthly plan ÷ 30.4.
/ inputs
your data beats generic averages.
If the campaign is new
Estimate CPA as AOV ÷ planning ROAS. Planning ROAS should come from contribution margin, variable costs and profit goals, not someone else’s benchmark.
30 and 50 conversions
These are useful Smart Bidding evaluation presets. Google recommends enough data for a sound evaluation, but does not call them a mandatory PMax launch minimum.
/ methodology
what Google actually says.
There is no single budget number for every account. Recommendations depend on goals, conversion history and the conversion cycle. Google describes typical calibration after changing an objective as 1–2 conversion cycles, not a guaranteed deadline. This calculator plans an average daily budget, not a campaign total budget.
| Budget | The advertiser sets an average daily budget. Google may provide an account-specific recommendation. |
| Learning | Duration depends on conversion volume, the conversion cycle and the bid strategy. |
| Evaluation | Google recommends a longer period with enough conversions for Smart Bidding evaluation; 50 is specifically noted for Target ROAS. |
/ UPLIFY data
context, not a market norm.
The UPLIFY sample covers 41 agency-managed projects and 129 campaigns from January to May 2026. Its UAH 101.46 median CPA combines account-configured Purchase, AddToCart, PhoneCall and FormSubmit actions. It must not be used automatically as purchase CPA. The 9.88× median ROAS also describes this selected portfolio, not the whole market.

short answers.
01What is the minimum budget for Performance Max?
Google does not prescribe one universal minimum. A practical plan depends on expected purchase CPA, the required conversion volume and the uncertainty buffer.
02Do I need 20–30 conversions per week to launch?
No. Official documentation does not state a universal PMax launch threshold of 20–30 weekly conversions. More high-quality conversions help learning and evaluation, but the required volume is account-specific.
03How long does the learning period take?
Duration depends on conversion volume, the conversion cycle and the bid strategy. Google describes typical calibration for a new objective as 1–2 conversion cycles, not a universal number of days.
04Does the calculated budget include advertising management?
No. The calculator plans ad spend, not the team’s management fee. Basic UPLIFY management starts at $320/month for ad spend up to UAH 50,000/month; the scope is agreed separately.
05Why not use the UAH 101 median CPA as a purchase forecast?
That dataset median mixes configured conversion actions, including AddToCart, calls and forms. A sales forecast needs purchase-only CPA.
