Rule of 72
This is a quick way to estimate how long it will take for your investment to double given a fixed annual rate of return. Simply divide 72 by the annual rate of return. For example, if your investment grows at 6% per year, it will take approximately 72 / 6 = 12 years for your investment to double.
The 50/30/20 Rule
This budgeting rule suggests that:
- 50% of your income goes to necessities (housing, food, utilities)
- 30% to discretionary spending (dining out, entertainment)
- 20% to savings and debt repayment
Dollar-Cost Averaging
This investment strategy involves regularly investing a fixed amount of money, regardless of market conditions. Over time, this can lower the average cost per share and reduce the impact of market volatility.
Emergency Fund
It’s recommended to have 3-6 months’ worth of living expenses saved in an easily accessible account. This can provide a financial safety net in case of unexpected events.
Compound Interest
The concept of earning interest on both the initial principal and the accumulated interest from previous periods. This can significantly increase your investment returns over time.
Diversification
A risk management strategy that involves spreading investments across various asset classes (stocks, bonds, real estate, etc.) to reduce exposure to any single asset.
Asset Allocation
This involves determining the proportion of various asset classes in your investment portfolio based on your risk tolerance, investment goals, and time horizon.
Time Value of Money
This principle states that a dollar today is worth more than a dollar in the future due to its potential earning capacity. This is why saving and investing early is crucial.
Net Worth Calculation
Your net worth is the difference between your assets and liabilities. It’s a good measure of your financial health and can guide your financial planning.
Credit Utilization Ratio
This is the percentage of your available credit that you’re using. A lower ratio is generally better for your credit score. It’s recommended to keep it below 30%.
