Financial advisor Jeff Rose talks about seven ways he makes money quickly. He explains the “Rule of 72,” a formula to determine how long it would take for an investment to double given a fixed annual interest rate. Assuming an average return of 10 percent, stock investments, for instance, would take 7.2 years to double in value. A high-yield savings account with an interest rate of 1.05 percent, on the other hand, would double in approximately 68.5 years.

To make money more quickly, Rose advises these methods:

Open an account with a trading service such as Robinhood or Webull, which offer free stocks for opening or funding an account or for inviting friends to join
Buy IPO stock
Flip sneakers purchased on Stockx on eBay or via the Snkrs app
Sell freelance services on the Fiverr platform
List and sell items from your garage or attic or that you find at garage sales on eBay
Flip internet domains using the Flippa platform
Buy an online learning course and apply the lessons
