sample size
Calculate the real sample size you need before trusting an A/B test result — using actual statistics.
n = (Z_α/2 + Z_β)² × [p₁(1−p₁) + p₂(1−p₂)] ÷ (p₂ − p₁)²
A/B Test Duration
test duration
Find out how many days your test actually needs to run at your current traffic level.
Days Needed = Required Sample Size per Variant ÷ Daily Visitors per Variant

Find out how much revenue your recovery emails could realistically bring back.
Recovered Revenue = Abandoned Carts × Average Cart Value × Recovery Rate
