GA4 サンプリング・コスト試算ツール
月間イベント数をもとに、Google アナリティクス 4 がレポートのサンプリングを始めるタイミングと、標準プランが上限に達する地点を試算します。
Total events across all reports in a typical month.
Rough share of events with a distinct value (e.g. unique URLs). 0.05 = 5%.
Likely to be sampled on standard GA4
15,000,000
estimated events per exploration query, against the 10,000,000 standard threshold
Standard sampling threshold
Monthly events
15,000,000
Est. events per query
15,000,000
Standard query limit
10,000,000
Est. unique values / day
25,000
Cardinality / "(other)" risk: Medium
You are above the 500 unique-values-per-day mark where GA4 treats a dimension as high-cardinality, so some long-tail values may move into "(other)".
How the tiers compare at this volume
GA4 standard (free)
Explorations sample above 10 million events per query. Cardinality limit of 50,000 values pushes the long tail into "(other)".
Analytics 360
Raises the per-query limit to as much as 1 billion events and lifts other limits. Sold on an annual contract through Google sales, so pricing varies and is not published publicly.
Zenovay
Reports are not sampled, so counts reflect the events that were actually recorded. Pricing is a flat plan fee rather than a number that climbs with volume. Plans have event allowances; check the pricing page for the fit.
Estimates are order-of-magnitude. Actual GA4 sampling depends on the specific query, date range, segments, and filters. Nothing here is sent to a server.
GA4 サンプリング・コスト試算ツールの使い方
- 1GA4 やアナリティクスのレポートから、月間イベント数（またはセッション数）の見込み値を入力します。
- 2探索レポートをどの程度使うかを選びます。探索は一度に多くのイベントを照会するためです。
- 31 クエリあたりの推定イベント数を、標準プランのサンプリングしきい値である 1,000 万件と比べます。
- 4カーディナリティの上限や「(other)」行に達しそうかどうかを確認します。
- 5標準プランの上限を、Analytics 360 や定額制の代替手段と比較します。
