Frequently Asked Questions
What is the debt snowball method?
The debt snowball method involves paying off your smallest debt balances first while making minimum payments on all other debts. Once a debt is paid off, you roll that payment into the next smallest debt, creating psychological momentum.
What is the debt avalanche method?
The debt avalanche method focuses on paying off debts with the highest interest rates first, regardless of balance size. This approach minimizes the total interest paid over time and is mathematically the most efficient strategy.
What is a FIRE number?
A FIRE number is the investment portfolio size needed to sustain your lifestyle indefinitely using the 4% safe withdrawal rate. It equals 25 times your annual expenses.
Is it better to rent or buy a home?
The rent vs. buy decision depends on your local market, how long you plan to stay, down payment size, and opportunity cost of capital. Our calculator compares the true total cost of both options over your analysis period.
