The Bottom Line
Your 30s are about building on the financial foundation of your 20s — or creating one if you haven’t yet. The priorities: increase retirement savings to 15%+, protect your income and family with insurance and estate planning, eliminate non-mortgage debt, and avoid lifestyle inflation. Time is still on your side, but the window for easy compounding is closing.
