Frequently Asked Questions

What is the 50/30/20 budget?

50% needs (housing, food, insurance), 30% wants (dining, entertainment), 20% savings and debt payoff. This is a starting framework — many people find their actual ratios are very different. Track your actual spending for a month first.

How do I track expenses automatically?

Apps like YNAB, Personal Capital, and Empower link to your bank accounts and categorize spending automatically. Mint was free but shut down. Most bank apps now offer basic expense tracking. Find one that works and actually use it.

What's the best way to cut expenses?

Audit fixed costs first (housing, insurance, subscriptions) — these have the biggest impact. Then variable costs (food, entertainment). Small daily purchases (coffee, subscriptions) add up more than most people realize. Use the 24-hour rule for non-essential purchases.
