📊 Revenue Growth Calculator

Revenue growth is the change in revenue divided by the starting figure. Growing from $850,000 to $1,020,000 is ($1,020,000 - $850,000) / $850,000 = 20.0 percent. Over multiple years the compound annual growth rate smooths the path into one yearly number. This calculator gives you both, plus the doubling time at the current pace.

Growth is the headline metric of every earnings call because it signals demand, but raw growth without context misleads. Twenty percent growth on shrinking margins is worse than 8 percent growth with expanding margins. Always read growth next to profitability.

How to Use This Calculator

Enter revenue for the earlier period and the later period, plus how many years apart they are. Use the same revenue definition for both: net revenue, same accounting, same scope.

The Growth Formulas

The simple growth rate works for one period. CAGR answers the multi-year question: what steady yearly rate gets from the start to the end? A company growing 50 percent then 0 percent shows 50 percent one-year growth but only 22.5 percent CAGR over two years. CAGR is the honest number for lumpy paths.

The rule of 72 shortcut: at g percent CAGR, revenue doubles in about 72/g years. Twenty percent CAGR doubles revenue in 3.6 years. It is approximate but instant, and our rule of 72 calculator runs it both directions.

Worked Example

$850,000 to $1,020,000 in one year. Growth = $170,000 / $850,000 = 20.0 percent. CAGR is the same 20.0 percent over one year. Doubling time = 72 / 20 = 3.6 years. Absolute gain: $170,000 of new annual revenue.

Multi-year version: $500,000 to $1,020,000 over 4 years. Total growth = 104 percent, which sounds spectacular. CAGR = (1,020,000/500,000)^(1/4) - 1 = (2.04)^0.25 - 1 = 19.5 percent. Still strong, but the CAGR tells you the yearly pace was under 20 percent, not 26 percent a year as the total divided by 4 would suggest. Never average growth rates arithmetically; compound them.

Growth Quality: What the Percent Hides

Organic, constant-currency, same-store growth is the gold standard; everything else needs an asterisk. When a company trumpets 30 percent growth, ask how much was acquisition, how much was price, and what happened to margin. Our revenue calculator builds the base figures this growth math starts from.

Benchmarking Growth

Context decides whether a growth rate is good. Twenty percent is pedestrian for a seed-stage startup and extraordinary for a mature manufacturer. Compare against three things: your own history (is the trend accelerating or fading?), direct competitors, and the market’s growth (growing slower than your market means losing share, whatever the absolute number). A useful discipline: report growth, margin change, and cash conversion together every quarter. Any one of them alone can be gamed; the trio rarely lies.

Growth vs Net Revenue Retention

For subscription businesses, revenue growth decomposes into new logos plus net revenue retention. A company growing 30 percent with 120 percent NRR gets most growth from existing customers expanding: the highest-quality kind. The same 30 percent with 90 percent NRR is on a treadmill, replacing churned revenue with expensive new sales. Headline growth hides the mix; the decomposition reveals it.

This is why NRR appears in every SaaS earnings call: it separates compounding from hustling. When evaluating any growth number, ask three questions: how much was new customers, how much was existing customers spending more, and how much was price versus volume. Growth from existing customers spending more is durable; growth from one-time deals is rented. The calculator above gives the headline; the mix gives the meaning.

The Base Effect

Growth percentages flatter small bases and punish large ones. Growing from $1 million to $2 million is 100 percent growth and $1 million of new revenue; growing from $100 million to $110 million is 10 percent and $10 million new. Headlines celebrate the 100 percent; shareholders should prefer the $10 million. Always pair the percentage with the absolute dollars, especially when comparing companies of different sizes.

The base effect also distorts trends: growth naturally decelerates as the base grows, which is mathematics, not failure. A company slowing from 60 to 30 percent growth while adding more absolute dollars each year is accelerating in the terms that matter. Judge the dollars, applaud the percentages, and never confuse the two.

Growth Investing vs Growth Trading

Investors pay for durable growth; traders rent temporary spikes. The difference shows in what happens after the beat: durable growers compound, spike traders revert. Distinguish them by source: pricing power and new customers compound, one-time orders and channel fill do not. The market eventually prices the source correctly, usually abruptly.

For operators, the implication is to build the compounding kinds: retention, expansion, pricing power. For investors, it is to discount the spike kinds ruthlessly. A 40 percent growth print from a one-time contract deserves a shrug; 15 percent from expanding existing accounts deserves attention. Growth quality beats growth quantity, every cycle, without exception.
