I'm a Ph.D. finance professor, but this is a basic high school math calculation. Just take the total gross increase, then annualize by raising to the power 1/years, and subtract 1. For example, a stock that doubled in 5 years got a compound return of 2^(1/5) -1 = 14.87%. A stock that multiplied fivefold in 10 years got a compound return of 5^(1/10) - 1 = 17.46%.


Thanks! I'm aware of this formula and use it in Excel for rough calculations. What I'm looking for is something more accurate and more comprehensive..

For example, I have stocks I originally purchased in the late 90s, added chunks along the way and have DRIP turned on. I'd like to be able to see ROR right now, ROR for each year, ROR trend (velocity) over time, etc so i can make decisions on when to keep or dump them. Gets too cumbersome in excel.

Past information is not an indication of a good investment. It's useless going forward.

I've been investing for 30+ years now and have a problem with not knowing which ones are growing fast vs not. For example, a stock I bought for $100 that is now worth $500 may seem like a good investment compared to another that I bought for $100 but is only $200. However, the first stock was bought 15 years ago while the second, last year. I want to know the Rate of Return for each stock/etf, be able to see ror growth, etc. The app/website should have plugins to brokerages to get cost/date info. to calculate this accurately. Any recommendations?
