Expansion MRR Calculator
Measure revenue gained from upgrades.
How the Expansion MRR Calculator works
Expansion MRR Calculator turns current mrr and expansion percent into expansion MRR. It computes that as current MRR times the expansion rate.
Worked example: with Current MRR 42000, Expansion percent 15, this tool returns expansion mrr 6300 USD, mrr after expansion 48300 USD. That default state is deterministic, so you can check the page against a known result before trusting your own numbers.
