Revenue Growth Calculator
Calculate month-over-month and year-over-year revenue growth rates. Project future revenue and benchmark your growth against industry standards.
Last updated: April 2026
Revenue growth rate measures the percentage increase in revenue over a specific period, typically month-over-month (MoM) or year-over-year (YoY). MoM Growth = ((Current Month Revenue − Previous Month Revenue) ÷ Previous Month Revenue) × 100. Pre-Seed / Seed typically target 15-25% MoM. Embed on your website to capture qualified leads.

What is Revenue Growth Rate?
Revenue growth rate measures the percentage increase in revenue over a specific period, typically month-over-month (MoM) or year-over-year (YoY). For startups, growth rate is the single most important metric — it determines fundraising ability, talent attraction, and market positioning. Consistent growth compounds dramatically over time.
The Formula
MoM Growth = ((Current Month Revenue − Previous Month Revenue) ÷ Previous Month Revenue) × 100 YoY Growth = ((Current Year Revenue − Prior Year Revenue) ÷ Prior Year Revenue) × 100
YoY growth eliminates seasonal fluctuations. MoM growth is more useful for early-stage companies tracking rapid changes.
Worked Example
A startup has $85,000 MRR this month, up from $78,000 last month and $42,000 twelve months ago.
- MoM Growth = ($85,000 − $78,000) ÷ $78,000 × 100 = 8.97%
- YoY Growth = ($85,000 − $42,000) ÷ $42,000 × 100 = 102.4%
- Annualized MoM: (1.0897)^12 − 1 = 179% (if sustained)
- ARR = $85,000 × 12 = $1,020,000
📌 With 9% MoM growth and 102% YoY growth, this startup is growing at a rate that attracts Series A investors. Sustaining 8%+ MoM leads to tripling revenue annually.
Why This Matters
Fundraising readiness
YC's benchmark: "A good growth rate is 5-7% per week, or 10-15% per month." Companies growing at 15%+ MoM generate FOMO among investors and raise on favorable terms.
Compounding effect
10% monthly growth for 12 months = 3.14x annual growth. 15% monthly = 5.35x annual. The difference between "good" and "great" monthly growth creates enormous annual gaps.
Market timing
Accelerating growth rate signals product-market fit. Decelerating growth (even if revenue is increasing) suggests market saturation or competitive pressure.
Common Mistakes
❌ Cherry-picking growth periods
Showing MoM growth after a big launch month and ignoring the plateau afterward is misleading. Use rolling 3-month averages for honest growth assessment.
❌ Confusing revenue with MRR
One-time revenue (consulting, setup fees) inflates growth in the month received. Track recurring revenue growth separately for SaaS businesses.
❌ Ignoring base effects
Growing from $1K to $2K MRR (100% growth) is very different from $500K to $1M (also 100%). As the base grows, sustaining high percentage growth becomes exponentially harder.
Industry Benchmarks
| Category | Good | Average | Poor |
|---|---|---|---|
| Pre-Seed / Seed | 15-25% MoM | 8-15% MoM | Below 5% MoM |
| Series A Stage | 100%+ YoY | 50-100% YoY | Below 40% YoY |
| Series B+ | 80%+ YoY | 40-80% YoY | Below 30% YoY |

From working with SaaS founders, the ones who embed a metrics calculator on their investor or pricing page consistently report shorter sales cycles — prospects arrive at the call already knowing their numbers.
One of the most common mistakes we see when working with clients: cherry-picking growth periods. Showing MoM growth after a big launch month and ignoring the plateau afterward is misleading. Use rolling 3-month averages for honest growth assessment.
