The 75/10/15 rule is a system designed to help you build wealth regardless of your income level, adapting whether you earn $10,000 or $1 million a year. It involves three key steps for every dollar you earn.

Allocate a maximum of 75% of your income for spending on necessities like housing, food, and other purchases. This limit encourages flexibility while forcing you to seek cheaper alternatives and focus on the value of your purchases, rather than cutting small expenses.

Save at least 10% of your income for a 'cushion fund,' a cash reserve specifically for financial emergencies. This fund should cover about five months of your monthly expenses and is best stored in a high-yield savings account (HYSA) for better interest rates compared to traditional savings accounts. Once your cushion fund goal is met, reallocate this 10%.

A Roth IRA is an individual retirement account where earnings and profits grow tax-free, meaning you pay no taxes upon withdrawal in retirement. Contributions are made with after-tax money, and there are annual contribution limits. Opening and investing in a Roth IRA involves having earned income, choosing a brokerage, transferring funds, and then purchasing investments within the account.

A 401K is an employer-sponsored account that allows pre-tax contributions. This means you pay taxes later, often when your income is lower in retirement. A major benefit is employer matching contributions, which essentially provides free money towards your retirement. The 401K has a much higher contribution limit and is a crucial tool for long-term wealth accumulation, especially when matched by an employer.

For most people, investing in index funds or ETFs is highly recommended. These funds, like an S&P 500 index fund, offer instant diversification by investing in hundreds of different stocks, reducing risk and allowing for a 'set it and forget it' approach. Historically, index funds have shown an average annual return of about 8%, contributing significantly to wealth growth over time.

Invest at least 15% of your income for your future, as real wealth is built by owning assets. The video highlights two key investment accounts with tax advantages: the Roth IRA and the 401K. These accounts allow your money to grow significantly over time through compounding, especially when investing in diversified options like index funds or ETFs.
