FAQ
What is a good MRR growth rate for early SaaS?
It depends on your base: 15–20%+ month-over-month is credible when you are small (a few thousand in MRR), but the same percentage is a fantasy at scale. These tools judge your growth against your base, not a flat number.
Is my growth target realistic or a hockey stick?
Work backwards to the monthly growth rate needed to hit your revenue target by your deadline. If that rate is far above what companies your size actually sustain, it is a hockey-stick fantasy — the Growth Reality Check quantifies it.
What is the Rule of 40?
Growth rate plus profit margin should add up to 40% or more for a healthy SaaS. It is a trade-off gauge: grow fast and burn, or grow slower and profit — as long as the two sum to about 40.
