A Fidelity margin account lets you borrow against your portfolio to buy more securities. The minimum equity requirement is $2,000, and Fidelity’s margin rates range from approximately 8.325% to 13.325% depending on your debit balance — meaning the more you borrow, the lower the rate. Margin amplifies both gains and losses, and Fidelity can issue a margin call or liquidate your positions if your equity falls below the required maintenance threshold.

How Fidelity Margin Works
When you open a margin account at Fidelity, you can borrow up to 50% of the purchase price of eligible securities (Regulation T requirement set by the Federal Reserve). This means:
- $10,000 in equity → can buy up to $20,000 in securities ($10,000 of your money + $10,000 borrowed)
- Leverage ratio: 2:1 (under Reg T)
- Maintenance margin: typically 30% of current market value (Fidelity sets this; FINRA minimum is 25%)
Worked Example
You have $10,000 in your Fidelity account and want to buy $15,000 of a stock trading at $50/share (300 shares).
- Your cash: $10,000
- Fidelity loan: $5,000 at ~11.825% interest
- Annual interest cost: ~$591
- Monthly interest cost: ~$49
If the stock rises 20% to $60: your 300 shares are worth $18,000. Sell, repay the $5,000 loan, and you net $13,000 minus $49 in monthly interest (if held 1 month). Your gain on $10,000 invested: 30% (vs 20% without margin).
If the stock falls 20% to $40: your 300 shares are worth $12,000. After repaying the $5,000 loan: $7,000. Your loss on $10,000: 30% (vs 20% without margin).
Margin doubles the sensitivity of your returns to price movements.
Margin Requirements at Fidelity
| Requirement | Standard | Pattern Day Trader |
|---|---|---|
| Initial margin (Reg T) | 50% | 25% (during day) |
| Maintenance margin | 30% | $25,000 minimum equity |
| Account minimum | $2,000 | $25,000 |
Pattern Day Trader (PDT) rule: If you execute 4 or more day trades within a rolling 5-business-day period in a margin account at Fidelity, you are classified as a Pattern Day Trader. This requires maintaining $25,000 in equity — if your equity falls below $25,000, Fidelity will restrict your account to 3 round-trip trades per rolling 5-business-day period until the equity is restored.
How to Apply for Margin at Fidelity
- Log in to your Fidelity brokerage account (margin is not available in IRAs)
- Navigate to Accounts & Trade → Account Features → Margin
- Complete the margin agreement — requires acknowledgment of margin risks and your financial information
- Wait for approval — typically same-day or next business day
- Begin trading on margin — your available margin balance appears in your account after approval
Your account must have at least $2,000 in equity before margin can be used.
Margin Calls at Fidelity
Regulation T call: If you do not deposit sufficient funds to meet the initial 50% margin requirement within 5 business days, Fidelity may liquidate securities to cover the shortfall.
Maintenance margin call: If your equity falls below 30% of your total market value, Fidelity issues a maintenance margin call. Unlike a Reg T call, Fidelity may liquidate your positions immediately without waiting 5 days. You will receive notification by phone, email, and within your Fidelity account.
How to avoid margin calls:
- Keep at least 40-50% equity buffer above the 30% maintenance threshold
- Never buy heavily correlated positions that can decline simultaneously
- Set price alerts for margined positions to monitor approaching maintenance thresholds
Is Margin Right for You?
Margin is suitable for investors who:
- Have a high risk tolerance and can absorb amplified losses
- Have a clear, time-limited reason to borrow (e.g., bridging a settlement gap, seizing a short-term opportunity)
- Understand that interest costs erode returns — at 11.825%, you need the investment to return more than 11.825% just to break even
Margin is not suitable for:
- Retirement accounts (not available in IRAs)
- Investors close to retirement who cannot afford amplified losses
- Buying highly volatile or illiquid securities
- Investors who do not monitor their accounts regularly
