Customer Expansion Revenue Matrix
See how monthly expansion compounds ARR over one, two and three years.
At 1.5% monthly expansion, existing customers alone take you to $3,418,279 in three years — 1.7× today, without a single new logo. For scale, note the gap: 1%/mo reaches $2,861,538 but 2%/mo reaches $4,079,775 over the same window.
Expansion compounds monthly, so small rate differences explode over time. This is why net revenue retention is the metric investors weight most.
