Paycheck & Earnings
Convert hourly ↔ weekly ↔ biweekly ↔ monthly ↔ annual, add overtime at 1.5×, estimate take-home.
What this book teaches
The everyday money math that decides whether you keep more of what you earn: reading a paycheck (hourly ↔ salary ↔ biweekly ↔ monthly, plus overtime), building a budget you'll actually stick to, watching compound interest work for you in savings — and against you in debt, paying down debt in the right order, shopping so a "deal" is actually a deal, understanding tax brackets without panicking, and pulling clean summaries out of your own money data. Series brand: Math Didn't Have To Be This Hard.
