UPLIFY commercial fit: UPLIFY usually takes on e-commerce engagements with at least UAH 30,000 per month in ad spend. This is an agency service-fit threshold, not a Google requirement and not a calculator floor.
Formula: purchase CPA × target purchases × (1 + buffer). Average daily budget = monthly plan ÷ 30.4.

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. Account recommendations depend on goals, conversion history and the conversion cycle. After a strategy change, learning may take up to 3 weeks or 1–2 conversion cycles.
| 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?
Google says duration depends on conversions, the conversion cycle and the bid strategy. After changes, it can take roughly 3 weeks or 1–2 conversion cycles.
04Why can the result be below UAH 30,000?
The calculator shows the mathematics of your inputs and does not round to an agency fee threshold. UAH 30,000 per month is a typical lower bound for UPLIFY’s engagement model, not a Google requirement.
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.
