How to Calculate YoY Growth: Step-by-Step (with Formula)
📐 Standard YoY formula: YoY % = ((Current Year Value – Previous Year Value) / |Previous Year Value|) × 100
- Identify your metric for the current period (e.g., Q1 2026 revenue = $65,000).
- Find the same metric from the prior year (Q1 2025 revenue = $50,000).
- Apply formula: ($65,000 – $50,000) / $50,000 = 0.30 → 30% YoY growth.
💡 Pro tip: If prior year value is negative (e.g., net loss), use absolute value to avoid distorted results – our calculator automatically handles edge cases.

Calculating YoY Growth for 3 Years & Average YoY
If you need to calculate yoy growth for 3 years or find the compound annual growth rate (CAGR), use the formula: CAGR = (End Value / Start Value)^(1/n) – 1. For example, revenue grew from $40k to $68k over 3 years → CAGR = (68/40)^(1/3)-1 ≈ 19.3% average annual YoY growth. Our built-in calculator above does this instantly.
Common pitfalls when calculating yoy growth
- Ignoring negative base years: Our calculator uses absolute values to deliver correct percentage change.
- Mixing nominal and real values: For 2026, adjust for inflation if comparing purchasing power.
- Using wrong period granularity: Always compare same month/quarter across years.
