- The result is 0.826446 , rounded for display.
How to interpret your result
Uses a constant effective discount rate per period.
Return measures must cover the same time period before comparison. CAGR annualises two endpoint values but does not model interim cash flows. Current income yield differs from total return or yield to maturity.
Frequently asked questions
