““Want to see how the investment income changes with a change in principal? Simply divide the figures by the change in principal. With a $20M portfolio (twice the principal) just multiply by two: instead of $40,000/month, you’d receive $80,000/month and $1M per year. With a $1M portfolio, divide the results by ten: instead of $40K per month, you’d live comfortably passive on $4,000/month and nearly $50,000/year.””
