🏛️ What is a Traditional IRA?
An Individual Retirement Account (IRA) is a tax-advantaged savings account you open independently - not through an employer - for long-term retirement savings. A Traditional IRA offers potential tax deductions on contributions and tax-deferred growth, meaning you don't pay taxes on investment gains each year. You pay ordinary income tax only when you withdraw money in retirement. This makes a Traditional IRA particularly valuable for people who expect to be in a lower tax bracket in retirement than during their working years.
For 2024, the IRA contribution limit is $7,000 per year ($8,000 for those 50 or older, with the catch-up provision). Contributions must be funded with earned income - wages, salaries, or self-employment income. Deductibility depends on your income and whether you or your spouse are covered by a workplace retirement plan like a 401k. If neither you nor your spouse has a workplace plan, contributions are always fully deductible regardless of income level.
The power of a Traditional IRA comes from tax-deferred compounding. Every dollar you would have paid in taxes stays invested and continues growing. Over a 30–35 year career, this tax deferral can add hundreds of thousands of dollars to your final balance compared to a taxable account growing at the same rate. Required Minimum Distributions (RMDs) must begin at age 73 under the SECURE 2.0 Act.
📐 IRA Growth Formula
The IRA balance formula combines the compound growth of the existing balance with the future value of annual contributions (annuity-due, contributions made at start of year). Annual tax savings is the immediate benefit of the deduction - if your marginal rate is 22% and you contribute $7,000, you save $1,540 in income tax that year. Over a career, these annual savings themselves compound significantly when reinvested.
