Frequently Asked Questions

The 50/30/20 rule: 50% needs, 30% wants, 20% savings. Aim for at least 15–20% for long-term financial security.
What is the FIRE number?
25Γ— your annual expenses (the 4% rule). If you spend $40K/year, you need $1M to retire indefinitely.
How do I start building an emergency fund?
Open a high-yield savings account. Start with $1,000, then build to 3–6 months of expenses. Automate monthly transfers.
Avalanche vs snowball debt payoff?
Avalanche (highest interest first) saves the most money. Snowball (smallest balance first) provides psychological wins. Both work β€” pick the one you will stick to.
