How Much Money Do I Need to Start an IRA? Broker Minimums

The belief that you need a small fortune to start investing for retirement is one of the most common financial myths. Many people delay opening an Individual Retirement Account (IRA) because they believe they must wait until they have saved up thousands of dollars.

In reality, the barrier to entry has never been lower. You can start an IRA today with almost nothing. However, while opening an account is virtually free, the actual amount of money you need to start investing inside that account depends on a few critical factors, including your choice of brokerage, your investment selection, and your personal financial goals.

Here is a comprehensive, practical guide on how much money you actually need to start an IRA, how to navigate broker minimums, and how to start building a retirement nest egg even on a tight budget.

The Short Answer: You Can Start with $0

If you want to open an IRA today, the minimum amount of money required by most major online brokerages is exactly $0.

Over the past decade, intense competition among brokerage firms has led to the elimination of account setup fees, annual maintenance fees, and minimum balance requirements for retail investors. This means you can open a Traditional or Roth IRA, get your account number, and link your bank account without depositing a single cent.

However, there is a fundamental distinction you must understand: opening an account is not the same as investing.

An IRA is simply a tax-advantaged container. Once you open the container, you must fund it with cash, and then use that cash to buy investments like stocks, exchange-traded funds (ETFs), or mutual funds. While the container itself costs $0 to open, the contents you buy inside it may have their own minimum requirements.

Account Minimums vs. Investment Minimums

To understand how much money you need to actually get started, you must separate the broker's rules from the investment vehicle's rules.

1. Brokerage Account Minimums

Most modern brokerages have a $0 account minimum. This applies to industry giants like Fidelity, Charles Schwab, and Vanguard, as well as modern robo-advisors like Betterment. You can open the account and let it sit empty if you wish.

2. Investment Minimums

Once your cash is in the IRA, you must purchase assets. This is where minimums come into play:

Mutual Funds: Historically, mutual funds have required minimum initial investments. For example, many of Vanguard's popular mutual funds (like their target-date funds) require a $1,000 minimum. Some of their specialized index funds require $3,000 or more. If you want to invest in these specific funds, you will need that lump sum to start.
Exchange-Traded Funds (ETFs) and Individual Stocks: ETFs and stocks trade like regular shares on an exchange. Historically, you had to buy at least one full share. If an ETF traded at $300, your minimum investment was $300.
Fractional Shares: Many modern brokerages now offer fractional share trading (sometimes called 'slices' or 'dollar-based investing'). This allows you to buy a fraction of a stock or ETF for as little as $1 to $5. If your broker offers fractional shares, your investment minimum is effectively $1.

Broker-by-Broker Comparison of IRA Minimums

To help you decide where to open your account, here is a breakdown of the minimum requirements at some of the most popular retirement account custodians:

Brokerage	Account Opening Minimum	Minimum to Buy Mutual Funds	Fractional Shares Available?	Best For
Fidelity Investments	$0	$0 (Fidelity Zero Funds)	Yes (Stocks & ETFs)	Beginners & DIY Investors
Charles Schwab	$0	Varies (Schwab funds often $1)	Yes (S&P 500 stocks only)	Broad investment selection
Vanguard	$0	$1,000 - $3,000	Yes (Vanguard ETFs only)	Long-term index fund investors
Betterment (Robo-Advisor)	$0	N/A (Automated portfolio)	Yes (Fully automated)	Hands-off, automated investing
Wealthfront (Robo-Advisor)	$500	N/A (Automated portfolio)	Yes (Fully automated)	Hands-off with advanced features

Fidelity Investments

Fidelity is arguably the most beginner-friendly broker for those starting with very little money. They offer a $0 account minimum, fractional share trading for as little as $1, and their proprietary 'Fidelity Zero' index funds, which have no minimum investment requirement and zero expense ratios. You can start a fully diversified retirement portfolio here with $5.

Charles Schwab

Schwab also offers a $0 account minimum. While they do offer fractional shares (called 'Schwab Stock Slices'), this feature is limited to S&P 500 companies, meaning you cannot buy fractional shares of low-cost ETFs. However, Schwab's own mutual funds have a $1 minimum, making them highly accessible.

Vanguard

Vanguard is the pioneer of low-cost indexing, but they have slightly higher barriers to entry for mutual funds. Their target-date retirement funds require a $1,000 minimum, and most index mutual funds require $3,000. However, you can bypass these minimums by purchasing Vanguard ETFs instead of mutual funds, which only requires the price of a single share (or less, if you buy Vanguard ETFs directly through a Vanguard account that supports fractional ETF shares).

The Cost of Delaying: The Power of Starting Small

Many people think, 'I only have $20 a week to save. I will wait until I can save $2,000 and then open an IRA.' This is a mathematical mistake.

Because of the power of compound interest, starting early with small amounts of money is far more effective than waiting to start with a larger sum. Time is the most valuable asset you have when building a retirement portfolio.

Consider this comparison of two investors, both earning an average 8% annual return on their investments:

Investor A (Starts Early, Small Amounts): Starts at age 22, contributing just $50 per month ($12.50 a week). They stop contributing entirely at age 32 (10 years of contributions, totaling $6,000 invested). By age 65, their account has grown to roughly $114,000.
Investor B (Waits to Save, Larger Amounts): Waits until age 32 to start because they wanted to wait until they could contribute $100 per month. They contribute $100 per month consistently for 33 years until age 65 (totaling $39,600 invested). By age 65, their account has grown to roughly $181,000.

Investor B invested more than six times as much money out of pocket as Investor A, yet ended up with only about 60% more in total value because they missed out on the critical compounding years of their twenties. If Investor A had kept contributing that $50 a month until age 65, they would have ended up with over $175,000 from a fraction of the daily financial sacrifice.

How to Start an IRA with Little Money: A Step-by-Step Guide

If you want to start your retirement savings journey today with a small budget, follow this step-by-step blueprint.

Step 1: Choose Your IRA Type (Roth vs. Traditional)

Before opening the account, you must choose between a Roth IRA and a Traditional IRA.

Roth IRA: You contribute after-tax dollars today. Your money grows tax-free, and your withdrawals in retirement are completely tax-free. This is generally best for younger investors or those currently in a lower tax bracket.
Traditional IRA: You contribute pre-tax or tax-deductible dollars today, lowering your taxable income this year. Your money grows tax-deferred, and you pay ordinary income tax when you withdraw the money in retirement. This is often preferred by high earners looking for an immediate tax break.

Step 2: Select a No-Fee, No-Minimum Custodian

Choose a broker that aligns with your budget. If you have less than $1,000, choose a platform like Fidelity, Charles Schwab, or a robo-advisor like Betterment. Avoid traditional retail banks for your IRA, as they often charge annual maintenance fees and offer low-yield savings products rather than true investment options.

Step 3: Set Up an Automated Micro-Transfer

Do not rely on your willpower to fund your IRA. Set up an automatic transfer from your checking account to your IRA timed with your payday. Even if it is only $5 or $10 per pay cycle, automating the process removes the friction of decision-making.

Step 4: Invest in Broad-Market ETFs or Fractional Shares

Once your money lands in the IRA, do not let it sit as cash. Cash inside an IRA does not grow and will lose purchasing power to inflation.

If your broker allows fractional shares, buy a broad-market index fund like an S&P 500 ETF or a Total Stock Market ETF.
If you are using Vanguard and do not have the $1,000 mutual fund minimum, buy a single share of a low-cost ETF.

Step 5: Turn on Dividend Reinvestment (DRIP)

When the companies or funds you own pay dividends, instruct your broker to automatically reinvest those dividends to buy more shares (or fractions of shares). This is a free service offered by almost all major brokers and accelerates the compounding process without requiring you to deposit more cash.

Hidden Fees to Watch Out For

While starting an IRA is cheap, you must keep an eye out for fees that can silently erode your portfolio over time. When you are starting with small amounts of money, fees represent a larger percentage of your total balance.

Expense Ratios: This is the annual fee charged by mutual funds and ETFs, expressed as a percentage of your investment. Look for index funds with expense ratios below 0.10%. Avoid funds with expense ratios above 0.50% unless there is a highly specialized reason to hold them.
Advisory Fees: If you use a robo-advisor, they will charge a management fee (usually around 0.25% of your assets per year). While reasonable for hands-off management, DIY investing through free index funds is cheaper.
Transfer Fees (ACAT Fees): While opening an account is free, moving your IRA to another broker in the future can cost between $50 and $100. Keep this in mind when choosing your initial custodian.

IRA Contribution Limits (2024 and 2025)

While there is virtually no minimum to start an IRA, the IRS does enforce a strict maximum on how much you can contribute each year. These limits apply across all your IRAs combined (you cannot bypass the limit by opening multiple accounts).

For 2024: The maximum contribution limit is $7,000 if you are under age 50. If you are age 50 or older, you can make a 'catch-up' contribution of an additional $1,000, bringing your total limit to $8,000.
For 2025: The maximum contribution limit remains $7,000 for those under age 50, and $8,000 for those age 50 and older.

Additionally, you must have earned income (from a job or self-employment) equal to or greater than the amount you contribute. If you only earn $3,000 in a year, your maximum IRA contribution for that year is capped at $3,000.

Start Where You Are

The answer to "how much money do I need to start an IRA" is simple: whatever you have right now. The financial industry has evolved to accommodate micro-investors. Do not wait for a windfall, a promotion, or a tax refund to secure your retirement. Open an account today, link your bank, deposit $5, and let the unstoppable engine of compound interest go to work for you.
