Cutting the welcome match cap from $500 to $150 raised contribution margin 19% with flat signups

Operator A/B on 8,800 registrations, casino, 60-day tracking.

Big headline bonuses feel like a conversion lever. This test priced that assumption.

Group A — 100% up to $500: signup-to-deposit 38%, bonus-cost/NGR 29%.
Group B — 100% up to $150: signup-to-deposit 37%, bonus-cost/NGR 17%.

The signup-to-deposit gap was one point — statistically noise on this sample. Almost nobody was depositing $500 to chase the max match; the median first deposit was $48 in both groups, so the $500 cap was mostly advertising the operator could never pay out.

Margin math: contribution margin/player (NGR minus bonus liability) rose from $94 to $112, +19%, on essentially identical acquisition.

The one real loss: the top 1% of depositors funded ~$210 less on average under the $150 cap. Worth a separate VIP-only high-cap offer rather than a blanket one.

Benchmark of the day: most welcome-match caps are 2–3× above the median first deposit — trimming the cap to ~3× median usually lifts margin with no signup cost.
