This Revenue Growth calculator measures how fast your sales are climbing. It handles period-over-period comparisons, compound annual growth rate (CAGR), and forward revenue projections in one place. If you've ever stared at two revenue figures and wondered whether 24% growth is actually good for your business type, or tried to build a 5-year CAGR in a spreadsheet and got lost halfway through, you're not alone. Read on and you'll also find out what growth rate investors typically expect, and how to run the same math in Excel.
From this page, you'll learn:
- How to calculate revenue growth between any two periods
- The difference between simple growth rate and CAGR (and when each one matters)
- What counts as "good" growth for retail, SaaS, and service businesses
- How to project future revenue using a monthly or annual growth rate

Worked Example: Priya tracks her skincare brand's year-over-year growth
Priya runs a direct-to-consumer skincare line. Last fiscal year she pulled in $84,700. This year she hit $109,140. She switches to Compare Periods mode and enters both figures.
Mode
Compare Periods
Initial Revenue
$84,700
Final Revenue
$109,140
Result: +28.86% growth, a dollar increase of $24,440. For an e-commerce skincare brand, that's well above the typical 15% to 25% benchmark. Priya's growth isn't just positive. It's competitive. Totally worth running the numbers.
What Is Revenue Growth?
Picture two snapshots of the same business, taken a year apart. The first shows $84,700 on the top line. The second shows $109,140. Revenue growth is simply the distance between those two numbers, expressed as a percentage so you can compare businesses of different sizes on equal footing.
A store that grew from $80,000 to $104,000 added $24,000. So did a company that went from $800,000 to $824,000. The dollar figure is identical. The percentage tells the real story: 30% versus 3%. That's why investors, lenders, and founders all reach for the growth rate before they reach for the raw revenue number.
Simple growth vs CAGR
Priya's 28.86% figure is a simple period-over-period growth rate. It compares two points in time and tells you the total change. But what if you want to know the average rate her revenue compounded each year over the past five years? That's CAGR, and it answers a different question.
Say Priya's revenue five years ago was $32,400. Today it's $109,140. The total growth looks huge, but it didn't happen all at once. CAGR smooths the path and gives you one number: roughly 27.5% per year. Investors love this figure because it strips out the noise of any single great or terrible year.
What counts as good growth?
Context matters more than the number itself. Rough benchmarks by business type:
| Business Type | Healthy Annual Growth |
|---|---|
| Retail | 5% to 10% |
| E-commerce | 15% to 25% |
| Professional services | 10% to 20% |
| SaaS / software | 20% to 40% |
| Early-stage startup | 30%+ |
So is 4% revenue growth good? For a mature retail chain with thin margins, 4% year-over-year is solid. For a Series A SaaS company, it's a red flag. And a 10% increase in revenue? That's strong for most established businesses, but it won't impress a venture investor backing a high-growth startup. The number only means something next to your industry and stage.
Note that revenue growth says nothing about profit. You can grow revenue 30% and still lose money if costs outpace sales. Investors who only look at the top line are missing half the picture. Now you know why context beats the raw percentage every time.
The Revenue Growth Formula
Let's walk through both formulas using Priya's numbers. The simple one first, then CAGR.
Period Growth Rate
((Final - Initial) / Initial) × 100
CAGR (Revenue Growth Rate)
((Final / Initial)^(1/n) - 1) × 100
- Initial RevenueRevenue from the earlier period (the starting point).
- Final RevenueRevenue from the more recent period (the ending point).
- nNumber of full periods between initial and final. For a 5-year CAGR, n = 5.
- Growth Rate (%)The result. Positive means revenue climbed. Negative means it dropped.
Priya's period growth calculation
Find the dollar change
$109,140 - $84,700 = $24,440
Growth = $24,440
Divide by initial revenue
$24,440 / $84,700 = 0.2886
Proportion = 0.2886
Multiply by 100
0.2886 × 100
Growth Rate = 28.86%
Priya's 5-year CAGR calculation
Five years ago her revenue was $32,400. Now it's $109,140. Let's plug in n = 5.
CAGR = (($109,140 / $32,400)^(1/5) - 1) × 100
CAGR = (3.3685^0.2 - 1) × 100
CAGR = 27.47% per year
So Priya's business compounded at roughly 27.5% annually over five years. Of course, you can skip all this counting and let the Revenue Growth calculator do it instantly.
Where Revenue Growth Actually Gets Used
Investor pitch decks and fundraising
Priya is preparing a seed round deck. Investors don't want to see one year's spike. They want CAGR over 3 to 5 years, plus a forward projection showing where revenue lands if current trends hold. She runs her historical numbers through CAGR mode, then switches to Forecast mode with a conservative 4% monthly growth rate to model the next 12 months. One slide, two numbers, both defensible.
Quarterly board reports
Kevin's agency went from $1.24M to $1.47M in Q3. That's 18.5% quarter-over-quarter. Compare Periods mode gives him the figure in seconds for his board deck.
What if you're planning next year's budget?
Consider a restaurant owner who averages $47,300 per month and expects 2.5% monthly growth after a menu refresh. She enters those into Forecast mode with 12 months ahead. The calculator projects roughly $61,800 by month 12 and shows a period-by-period breakdown she can drop straight into her cash flow forecast. She also adds a 15% seasonal bump in December to account for holiday traffic. And now she knows what revenue to plan staffing and inventory around.
Spotting a slowdown before it becomes a crisis
Revenue growth that drops from 22% to 8% year-over-year isn't a disaster on its own. But if your industry typically grows at 15%, that deceleration is a warning sign worth investigating before the next quarter closes. 📉
Period Growth vs CAGR: Where People Get It Wrong
Here's where most people get confused about revenue growth: they use the simple period-over-period formula when they mean CAGR, or they compare a one-year spike to a multi-year compound rate and wonder why the numbers don't match.
Say a company's revenue went from $500,000 to $750,000 in one year. Simple growth is 50%. Impressive. But if revenue was $500,000 three years ago and is $750,000 today, the CAGR is only about 14.5% per year. Still healthy. Just a very different story than 50%.
See the difference? Simple growth captures the total change between two points. CAGR spreads that change evenly across every year in between. Use simple growth for quarter-over-quarter or year-over-year snapshots. Use CAGR when you're comparing multi-year performance or benchmarking against investor expectations.
Another trap: comparing QoQ growth to YoY growth directly. A business can post 8% quarter-over-quarter growth and still be down 3% year-over-year if the prior quarters were weak. Always label which comparison you're running. Your results may vary slightly if the periods aren't aligned to calendar quarters, so double-check your date ranges before presenting the number.
That's why the calculator separates Compare Periods and CAGR into distinct modes. Pick the one that matches the question you're actually asking.
FAQs
How do you calculate revenue growth?
Subtract your earlier period revenue from your more recent period revenue, divide by the earlier figure, and multiply by 100. So if you went from $84,700 to $109,140: ($109,140 - $84,700) / $84,700 × 100 = 28.86%. That's your growth rate. The dollar change ($24,440) is useful too, but the percentage is what lets you compare against other businesses or prior periods on equal footing.
What is a good percentage of revenue growth?
It depends entirely on your industry and stage. For most established retail businesses, 5% to 10% year-over-year is healthy. E-commerce brands typically target 15% to 25%. SaaS companies often aim for 20% to 40% annually. Early-stage startups are usually expected to grow 30% or more. The number only makes sense in context. A 4% growth rate might thrill a mature grocery chain and worry a venture-backed software company.
Is 4% revenue growth good?
For many established, profitable businesses, yes. A 4% year-over-year increase on a $2M revenue base adds $80,000 in new sales without requiring aggressive expansion. That's steady, sustainable growth. But if you're a high-growth startup pitching investors who expect 30%+ annually, 4% won't move the needle. Check the benchmarks table above for your business type before deciding whether your number is strong or soft.
How do you calculate a 5 year growth rate?
You use the CAGR formula. Here's the step-by-step: (1) Find your starting revenue from 5 years ago and your current revenue. (2) Divide final by initial. (3) Raise the result to the power of 1/5. (4) Subtract 1 and multiply by 100. Example: revenue went from $32,400 to $109,140 over 5 years. ($109,140 / $32,400)^(1/5) - 1 = 0.2747, or 27.47% CAGR. Switch to CAGR mode in the calculator, enter all three values, and it handles the exponent for you.
How do you calculate revenue growth in Excel?
For simple period growth, put initial revenue in cell A1 and final revenue in B1. In C1, type: =(B1-A1)/A1*100. That gives you the growth percentage. For CAGR over n periods, use: =(B1/A1)^(1/n)-1, then multiply by 100 for a percentage. Replace n with the number of periods (e.g. 5 for five years). If you want a full projection, put your starting revenue in A1, growth rate (as a decimal) in B1, and use =A1*(1+$B$1) in A2, then drag down for each period. Or just use the Forecast mode here and skip the spreadsheet setup entirely.
