MRR = Sum of all monthly subscription revenues at the start of the month. Annual subscriptions are divided by 12. New MRR + Expansion MRR - Churned MRR - Contraction MRR = Net MRR change.
For Indian SaaS, MRR is reported in INR. Most India-based SaaS at ₹5L MRR = ₹60L ARR is the early stage; ₹50L-₹2Cr MRR = scale stage; above ₹5Cr = growth stage.
MRR ≠ revenue. A customer paying ₹12,000 annual subscription contributes ₹1,000 MRR. Cash-collected metric is different and matters for runway calculations.
