Revenue Growth Calculator – % Change YoY

Growth is the percentage change between two revenue periods: subtract prior from current, divide by prior, multiply by 100. Worked example: revenue rising from $350,000 to $410,000 grows (410,000 − 350,000) ÷ 350,000 = 17.1% year over year. For multi-year comparisons use CAGR — three years from $200k to $340k is (340 ÷ 200)^(1/3) − 1 = 19.4% annually — because simple averaging hides compounding. Watch that price hikes can print growth while volumes actually shrink. Also separate recurring from one-time revenue so contract timing cannot fake a trend that is not really there.

1. 1

   Enter prior revenue

   The baseline period: last year or last month.

2. 2

   Enter current revenue

   The newest period of the same length.

3. 3

   Read growth %

   Positive means expansion, negative flags contraction.

• Mixing periods of unequal length (5 months vs 12)

• Celebrating growth that came purely from a price hike on shrinking volume

• Averaging yearly growth rates instead of compounding CAGR
