It's possible you might already have enough saved up for retirement, thanks to the power of compounding—a phenomenon in the FIRE community known as Coast FI. We cover how to calculate that number, if it's a reliable safety net, and what else to keep in mind. Rich Girl Roundup is Money with Katie's weekly segment where Katie and her Executive Producer Henah answer your burning money questions. Each month, we'll put out a call for questions on her Instagram (@moneywithkatie). New episodes every week.
