How to Find Growth Rate: A Complete Guide for Global Businesses

Every business wants to grow—but measuring that growth accurately is just as important as achieving it. In the fast-paced U.S. economy, where SaaS companies, eCommerce stores, and startups fight for market share, understanding your growth rate can make or break your strategy.

Growth rate isn’t just about how much money you made last quarter or how many customers signed up last month. It’s about trends—how fast your business is moving compared to competitors, and whether you’re gaining or losing momentum.

This guide will walk you through everything you need to know about finding growth rate: the formulas, the step-by-step process, different types of growth rates (like revenue growth, market share growth, and user growth), and real-world U.S. business examples. By the end, you’ll not only know how to calculate growth rates but also how to use them to make smarter business decisions.

What Is Growth Rate?

At its simplest, growth rate measures the percentage change in a specific metric over a set period of time. That metric could be:

• Revenue (sales growth)

• Number of customers (user growth)

• Market share (competitor comparison)

• Even a country’s economy (GDP growth rate)

Instead of looking only at raw numbers, growth rate helps you understand speed and direction. A company growing revenue from $1 million to $1.5 million has a 50% growth rate—a much more powerful insight than just saying “we made half a million more.”

Why Does Growth Rate Matter?

• Investors look at growth rates, not just revenue. U.S. venture capital firms often fund startups based on CAGR (Compound Annual Growth Rate).

• Executives use growth rates to guide hiring, expansion, and marketing budgets.

• Economists use GDP growth rates to analyze the overall health of the U.S. economy.

In short: if you want to benchmark success, you need to know your growth rate.

The Growth Rate Formula

The basic formula to calculate growth rate is:

Growth Rate = End Value – Start Value / Start Value × 100

Step-by-Step Example

Imagine your SaaS company earned $200,000 in ARR (Annual Recurring Revenue) last year and $300,000 this year.

• Start Value = 200,000

• End Value = 300,000

Growth Rate = 300,000 – 200,000 / 200,000 × 100 = 50%

That means your business grew 50% year-over-year.

Variations of the Formula

• CAGR (Compound Annual Growth Rate): Used for multi-year growth.

• Average Annual Growth Rate (AAGR): Average of growth rates across years.

We’ll break these down in detail later.

How to Find Growth Rate in 4 Simple Steps

Step 1: Pick the Metric That Matters

Growth rate is flexible. You can calculate it for revenue, users, market size, or even web traffic. For SaaS companies, revenue growth is usually the top metric.

Step 2: Find Your Starting Value

This is the baseline figure from your first time period (e.g., revenue in Q1, or total users last year).

Step 3: Find Your Ending Value

This is the updated figure from your second time period (e.g., revenue in Q2, or total users this year).

Step 4: Apply the Formula

Plug both numbers into the formula and multiply by 100 to get a percentage.

Quick Example: User Growth

• January users: 5,000

• June users: 8,000

Growth Rate = 8,000–5,000 / 5,000 × 100 = 60%

Your user base grew 60% in six months.

Different Types of Growth Rates

1. Revenue Growth Rate

Revenue growth is the most common and most important metric for Global Businesses.

Revenue Growth Rate = Current Revenue – Previous Revenue / Previous Revenue × 100

Example:
If your SaaS company earned $1M last year and $1.2M this year:

1.2M–1M / 1M × 100 = 20% growth

2. Market Share Growth Rate

Measures how much more of the total U.S. market your business controls compared to competitors.

Formula:

Market Share Growth Rate = Current Market Share – Previous Market Share / Previous Market Share ×100

Example:
Your streaming platform had 10% U.S. market share last year and 15% this year.

15 – 10 / 10 × 100 = 50%

That’s 50% growth in market share—a huge competitive advantage.

3. User Growth Rate

Tracks the number of new paying customers or active users over time. Critical for SaaS and mobile apps.

Formula is identical to revenue growth but applied to users.

4. Compound Annual Growth Rate (CAGR)

CAGR smooths out growth over multiple years.

CAGR = (Start Value / End Value)^n/1 - 1

Where n = number of years.

Example:
Revenue grew from $100K to $300K in 3 years.

CAGR = (300,000 / 100,000)^1/3 –1 = 44.2%

That means your business grew 44.2% annually on average.

5. Average Annual Growth Rate (AAGR)

AAGR = average of year-over-year growth rates. Useful for trend analysis but less precise than CAGR.

Why Growth Rate Matters for Global Businesses

• Investor Relations: U.S. venture capitalists want double-digit annual growth rates before funding startups.

• Benchmarking: Compare your company’s growth against industry averages. For example, U.S. SaaS companies average ~30–40% ARR growth in early stages.

• Hiring & Expansion Decisions: Strong growth rates justify expanding teams or opening new markets.

• Competitive Strategy: Market share growth reveals whether you’re winning or losing ground in the U.S. market.

Practical Tools to Calculate Growth Rate

• Excel / Google Sheets: Use = (End – Start) / Start for quick calculations.

• Online Calculators: Free growth rate calculators exist on financial websites.

• BI Tools: Tableau, Power BI, and Looker automate growth tracking.

• SaaS Analytics: Platforms like Mixpanel and Amplitude give deeper insights into user and revenue growth.

Common Mistakes When Measuring Growth

1. Using Too Short a Timeframe – Seasonal spikes can distort results.

2. Ignoring Churn – Revenue growth without considering churn gives a false picture.

3. Confusing Gross vs. Net Growth – Always account for lost customers or revenue.

4. Focusing on Vanity Metrics – User sign-ups matter less if they don’t convert to paying customers.

Real-World Examples

• eCommerce: A U.S. online retailer grew from $2M to $2.8M in sales YoY = 40% growth.

• SaaS Startup: Gained 5,000 users in Q1 and 8,500 in Q2 = 70% growth in one quarter.

• Streaming Industry: A competitor’s market share jumped from 12% to 18% = 50% growth in market share.

Growth Rate in Economic Context

Growth rates aren’t just for companies—they apply at the national level too.

The U.S. Bureau of Economic Analysis reports quarterly GDP growth. When GDP growth is high, businesses often see stronger revenue growth. During slowdowns or recessions, even fast-growing startups may face investor skepticism.

FAQs on How to Find Growth Rate

Q1: What’s the easiest way to calculate growth rate?
 Use the formula (End – Start) / Start × 100.

Q2: How do I calculate monthly vs. annual growth rate?
 Use the same formula but adjust your timeframe. For CAGR, divide by years.

Q3: What is a good growth rate for SaaS?
 In the U.S., early-stage SaaS companies often target 30–50% annual revenue growth.

Q4: What’s better: CAGR or YoY growth?

• CAGR smooths multi-year trends.

• YoY shows sharper short-term changes.

Q5: Can negative growth rates be useful?
 Yes. They reveal decline and help businesses identify when to pivot strategies.
