Frequently Asked Questions
What is Year-Over-Year (YoY) Growth Rate?
YoY Growth Rate compares financial metrics (such as ARR or revenue) in a given period to the exact same period in the previous year, eliminating seasonal fluctuations.
What is the formula for YoY Growth Rate?
YoY Growth Rate (%) = [(Current Year Revenue − Prior Year Revenue) / Prior Year Revenue] × 100.
What is a good YoY growth rate for SaaS startups?
Early-stage SaaS startups ($1M–$10M ARR) typically target 100%–300%+ YoY growth (“Triple, Triple, Double, Double”). Mature B2B SaaS companies ($50M+ ARR) benchmark at 30%–50%+ YoY.
How does YoY growth differ from MoM growth?
Month-over-Month (MoM) tracks short-term monthly changes, whereas Year-over-Year (YoY) tracks 12-month annual growth momentum and irons out seasonal noise.
What is the T2D3 growth framework in SaaS?
T2D3 stands for “Triple, Triple, Double, Double, Double”—a venture growth benchmark where a startup grows from $1M to $3M (3x), $3M to $9M (3x), $9M to $18M (2x), $18M to $36M (2x), and $36M to $72M (2x).
Can YoY growth rate be negative?
Yes. If current year revenue is lower than prior year revenue, the resulting YoY growth rate is negative, indicating revenue contraction.
How do venture capitalists evaluate YoY growth against Rule of 40?
VC investors combine YoY revenue growth rate percentage with free cash flow margin to calculate Rule of 40 financial efficiency.
