You may already know that the word ‘percent’ means ‘per 100.’ Thus, 1000% implies 1000/100 = 10. So, if you invest $5000 and get a 1000% return, the return value will be 10 x $5000 = $50,000.
Similarly, a 10,000% gain implies that 10000/100 = 100. And the return calculation method remains the same.
