What is the FIRE movement?
FIRE stands for Financial Independence, Retire Early. It's a lifestyle movement focused on aggressive saving and investing — typically 25-50% of income — to build enough wealth to cover living expenses indefinitely. The goal is to reach a portfolio large enough that investment returns cover your annual spending, often using the 4% withdrawal rule.
How much should I have in an emergency fund?
Most financial experts recommend 3-6 months of expenses, but the right amount depends on your situation. Freelancers and those with variable income should aim for 6-9 months. If you have dependents or a single income household, lean toward the higher end. Keep emergency funds in a high-yield savings account for easy access.
Is it better to rent or buy a home?
There's no universal answer — it depends on how long you plan to stay, local home prices vs rents, mortgage rates, and your financial situation. Generally, buying makes more sense if you plan to stay 5+ years and can afford a 20% down payment. Renting offers flexibility and avoids maintenance costs. Use our Rent vs Buy calculator to compare your specific numbers.
How do I audit my subscriptions?
Start by listing every recurring charge on your credit cards and bank statements. Categorize each as essential, nice-to-have, or unnecessary. Cancel anything you haven't used in the last 30 days. For services you keep, check if annual plans offer savings. Most people find $50-200/month in subscriptions they forgot about or rarely use.
What is the difference between short-term and long-term capital gains tax?
Short-term capital gains (investments held less than one year) are taxed at your ordinary income tax rate, which can be as high as 37%. Long-term capital gains (held one year or longer) get preferential rates of 0%, 15%, or 20% depending on your income. Holding investments longer than a year can save you thousands in taxes.
Should I use the snowball or avalanche method to pay off debt?
The avalanche method (targeting highest interest rate first) saves the most money mathematically. The snowball method (targeting smallest balance first) provides quicker wins that keep you motivated. Research shows snowball has higher completion rates, but avalanche saves more on interest. Choose the one you'll stick with — the best strategy is the one you follow consistently.
