The four levers of SaaS MRR growth
New MRR, expansion MRR, contraction MRR, and churn MRR are the only four numbers that determine where your ARR ends up. Most growth-stage SaaS companies discover that expansion MRR — driven by upsells, seat growth, and tier upgrades — eventually exceeds new MRR. Companies that ignore expansion ship a leaky bucket. The calculator surfaces the compounding impact of each lever.
