There is one inspiring story about Rachel Fox, who had already made a name for herself as a successful actress at just 16 years old. But she didn’t stop there – she was also passionate about investing and finance. She used her earnings from acting to invest in companies like Google and Amazon, and she was able to grow her portfolio to over $50,000 by the time she was 18. Fox went on to study economics at Columbia University and started her own consulting firm, Fox Finance Group.

Personal finance definition

Personal finance refers to managing financial resources to achieve certain goals and objectives. This concept encompasses a broad range of topics that fall into one of five categories:

Income: all sources of cash flow, such as salary, pension, social security, and investment income from rental properties or stocks
Spending: any expenses an individual may have
Savings: a portion of income for future expenses, both planned and unplanned
Investing: financial products such as stocks, bonds, or real estate with the expectation of earning future income
Protection: various products like annuities, property/casualty insurance, life insurance, and health insurance

What to do in your 20s

Establish good financial habits by creating a budget, tracking expenses, and avoiding high-interest debt. Build an emergency fund and invest in your education and career to maximize your opportunities later.

Also, start saving at least 10% of your income as soon as possible, and consider saving 15% or more for retirement.

What to do in your 30s

Focus on your increasing savings and paying off high-interest debt. Build and grow a diversified investment portfolio, regularly top up an emergency fund, and review insurance policies.

Consider investing in yourself by furthering your education or starting a business to increase your earning potential.

What to do in your 50s

Get adequate insurance coverage, including life, disability, and liability insurance, to protect your income and assets. Maximize contributions to your retirement plan and consider catch-up contributions to make up for any gaps in savings.

Perhaps you can downsize your home to reduce expenses or use your home equity to fund retirement or pay off debt.

What to do in your 60s

With retirement approaching, create a comprehensive plan that includes a budget and an investment exit strategy. Think about your legacy and consider creating an estate plan, including a will and trusts, to ensure your assets are distributed according to your wishes.

Unfortunately, older adults are often targeted by financial scams, so stay vigilant and educate yourself on common scams to avoid falling victim.
