Firsts: the big life moments

First car, first home, marriage, family

Everyone hits the same money moments. First car. First home. Marriage. Career change. Starting a family. Retirement. These decisions shape finances for years. Getting them right matters more than daily habits.

Most people stumble through because nobody showed them the playbook. They overpay, under-plan, or get locked into deals they regret. Goal: make each on purpose, not by accident.

Short guide to the big ones.

Key points

• First car: total cost, not monthly payment. Full loan amount plus interest, insurance, fuel, maintenance. Bigger down payment keeps you from being upside-down. Research edmunds.com, consumerreports.org, carfax.com before shopping.
• First home: use the 28/36 rule. Housing ≤ 28% of gross income. Total debt ≤ 36%. Buy when you plan to stay 5+ years, have stable income, and can put 10 to 20% down without emptying savings.
• Marriage: have the money talk early. Weekly or monthly check-ins. Appoint a household CFO who runs bills and budget. Decide what to merge and what to keep separate. Update beneficiaries on every policy.
• Career change: protect the transition. Roll your old 401(k) into an IRA or new employer plan. Don't leave it behind. Adjust budget before income changes land. If income drops, shrink expenses first.
• Family: plan cash flow before the emotion. Childcare alone runs $12,000 to $24,000/yr. Then health insurance, bigger groceries, eventually education. Grow the emergency fund and cut debt before expanding the family.
• Retirement: just math, started early. Most people need 70 to 80% of working income to maintain lifestyle. A $250K 401(k) drawing $27K/yr runs out in about 10 years. Start early and build a second income stream.
