Estimate affordability, compare financing, and see how extra payments change the long-term cost of ownership.
Calculate average investment returns and CAGR
Total ROI: (Final Value - Initial Investment) / Initial Investment × 100%
CAGR: Compound Annual Growth Rate = [(Final/Initial)^(1/Years) - 1] × 100%
Arithmetic Mean: Simple average of periodic returns. Example: (10% + 20% + 5%) / 3 = 11.67%
Geometric Mean: Accounts for compounding. More accurate for investment returns over time.
Why Different? Arithmetic mean is always higher than geometric mean when returns vary. Geometric mean better represents actual growth.
Example: $10,000 growing to $18,000 in 5 years has CAGR = 12.47% per year
