I'm tracking a few investments, with a simple formula for total (non-annualised) return, which is (current_value - money_invested) / money_invested
. For one of my investments, however, I already partially cashed out (for more than the total original investment), which makes the formula yield negative.
For the sake of argument, let's say the numbers are:
- Invested $1000
- After it grew to $3000, I sold $1500 worth.
- So I now have "spent" -$500 to acquire an asset worth $1500, yielding a return of
(1500 - -500)/(-500)
or -400%.
Is there a more meaningful calculation I can do in this case?
