Frequently Asked Questions

What is a FIRE number?

Your FIRE number is the portfolio size needed to cover annual expenses through investment withdrawals alone. It is calculated as annual expenses divided by the safe withdrawal rate. For example, if you spend $45,000/year with a 4% withdrawal rate, your FIRE number is $1,125,000.

Is a 4% withdrawal rate safe?

The 4% rule comes from the Trinity Study, which found that withdrawing 4% annually from a diversified portfolio historically sustained 30+ years of retirement. However, some planners recommend 3-3.5% for early retirees with 40-50 year time horizons.

How much should I save each month?

Financial experts recommend saving at least 20% of your income using the 50/30/20 rule: 50% for needs, 30% for wants, and 20% for savings and debt repayment. The exact amount depends on your goals and timeline.

What is the best way to automate savings?

Set up automatic transfers from checking to savings on payday, use your employer's direct deposit to split funds between accounts, or use apps that round up purchases and save the difference.
