How do I start saving money when I live paycheck to paycheck?

Start by tracking every dollar you spend for one month using a free app like Mint or even a notebook. Most people discover spending leaks they didn't notice, like subscriptions, frequent takeout, or impulse purchases. Even cutting $20-30 a week adds up significantly over time. Then automate a small transfer, even $10 or $25, to a separate savings account the day you get paid. Treating savings like a bill you must pay prevents you from spending it first. Look at reducing your three biggest expenses, typically housing, food, and transportation, since small cuts there beat skipping coffee. Build a small $500 emergency fund first before any other savings goal, so unexpected costs don't derail your progress.
