📝 Complete Guide to CAGR in the UK
This CAGR calculator UK helps you measure the Compound Annual Growth Rate of your investments. CAGR is the most accurate way to compare investment performance across different time periods and asset classes.
📊 What is CAGR?
CAGR (Compound Annual Growth Rate) measures the annualized return of an investment, smoothing out volatility:
- Formula: CAGR = (End Value / Start Value)^(1/years) - 1
- Example: £10,000 to £16,500 in 5 years
- Calculation: (16,500/10,000)^(1/5) - 1 = 10.5%
- Total Return: 65% over 5 years
💡 Why CAGR Matters for UK Investors
- Comparable Returns: Compare investments with different time periods
- Smooths Volatility: Shows consistent annual growth rate
- Performance Tracking: Measure portfolio performance accurately
- Goal Planning: Set realistic investment targets
- Peer Comparison: Compare against UK market averages
📈 UK Investment CAGR Examples
- FTSE 100 (10 years): £10,000 → £21,500 = 7.9% CAGR
- UK Property (10 years): £200,000 → £350,000 = 5.8% CAGR
- Global Equities (10 years): £10,000 → £22,600 = 8.5% CAGR
- Tech Fund (10 years): £10,000 → £31,000 = 12% CAGR
📊 CAGR vs Average Return
Understanding the difference is crucial:
- Average Return: Arithmetic mean of annual returns
- CAGR: Geometric mean showing compound growth
- Example: Returns +20%, -10%, +15%
- Average: (20-10+15)/3 = 8.3%
- CAGR: (1.20×0.90×1.15)^(1/3)-1 = 7.4%
- Why: CAGR accounts for compounding and volatility
