Definition
An IRA is a personal retirement account with special tax benefits designed to encourage saving for retirement. The IRS has contribution limits (currently $7,000 annually for those under 50), and withdrawals before age 59 1/2 typically trigger penalties. There are two main types: Traditional IRAs (contributions may be tax-deductible now, withdrawals are taxed later) and Roth IRAs (contributions are after-tax, qualified withdrawals are tax-free). Each has different advantages depending on your situation.
Why it matters
IRAs are a core retirement savings tool because they save you money on taxes. A Traditional IRA contribution of $7,000 might reduce your taxes by $1,400 (if you're in the 20% bracket), creating an immediate 20% return on your money. A Roth IRA contribution of $7,000 costs you $7,000 in taxes now but gives you tax-free growth for 40+ years through compounding. Over time, the tax advantages on both can add up to hundreds of thousands in extra retirement savings.
Quick example
At age 30, you contribute $7,000 to a Roth IRA earning 8% annually. By age 70, you have about $1.6 million. You paid $7,000 in taxes upfront but owe zero taxes on all that growth. In a taxable account, you'd owe roughly 20% in capital gains taxes on the gains ($256,000), leaving you with $1.45 million. The Roth saved you $160,000+ in taxes by avoiding capital gains on four decades of compounding.
The bottom line
Knowing what IRA (Individual Retirement Account) means helps you make better day-to-day money decisions. It makes rates, account options, and tradeoffs easier to compare.
