Fidelity Margin Rates: The Full Schedule, Plainly

ByRobby Naka

I opened a margin account at Fidelity once, moved exactly zero dollars into a trade, and got out. Not because I chickened out, and not because Fidelity did anything shady. I just did the math on what borrowing at 11-plus percent would cost me, looked at my brokerage balance, and realized I would be paying credit-card money to gamble on the stock market with training wheels. So I closed the tab. That is roughly what I want to hand you before you decide anything about a margin account.

Fidelity margin rates are a tiered schedule that runs from about 11.825% on small debit balances down to around 7.50% on balances above one million dollars, tied to a base rate (10.575% as of late 2025) that moves with the federal funds rate. That is the entire fact of the matter. Everything else, every “should I use margin” question, comes down to whether that number is worth it for what you actually want to do.

I am not a financial advisor. I am a personal-finance guy who has poked at a margin account, walked away from it, and watched a couple of friends use one intelligently. What follows is what Fidelity charges, how the tiers work, what the bill actually looks like in dollars, how to turn margin on (and off), when it makes any sense for a normal person, and when it is a fast way to lose real money on a boring Wednesday.

The current Fidelity margin rate schedule

Fidelity publishes its margin schedule as a base rate plus (or minus) a spread that depends on the size of your outstanding balance. As of the most recent update in late 2025, the base rate is 10.575%. Here is what that produces at each tier.

  • Under $25,000: base + 1.25% = around 11.825%
  • $25,000 to $49,999: base + 0.75% = around 11.325%
  • $50,000 to $99,999: base – 0.20% = around 10.375%
  • $100,000 to $249,999: base – 0.25% = around 10.325%
  • $250,000 to $499,999: base – 0.50% = around 10.075%
  • $500,000 to $999,999: base – 2.825% = around 7.75%
  • $1 million and up: base – 3.075% = around 7.50%

Two things to notice. The first is that the tiers are not evenly spaced. Fidelity drops the rate by tiny amounts as you move from small to mid balances, then chops off almost three full percentage points once you cross half a million dollars. That is not a bug. It is a pricing strategy that rewards very large borrowers and charges everyone else close to a credit-card rate without making noise about it.

The second is that the base rate is not static. It tracks the federal funds rate. When the Fed hikes, your margin bill goes up the next month, whether you were watching or not. The schedule you see today is a snapshot; always spot-check the current numbers on the official Fidelity margin rates page before you actually pull the trigger on anything.

How Fidelity margin interest is actually calculated

The formula is old-school and boring, which is good, because it means it does what it says. Margin interest at Fidelity accrues daily on your debit balance at whatever rate your tier lands you at, and it gets posted to your account monthly. There is no principal payment schedule, no minimum monthly payment, no amortization. The interest just piles on top of the balance until you either sell the securities backing the loan, deposit cash to pay it down, or transfer new funds in.

The rough back-of-napkin math: your daily interest is (debit balance × annual rate) divided by 360. So if you carry a $10,000 margin balance at 11.825%, you are paying roughly $3.28 a day, or a hair over $98 a month, or about $1,180 for a year. That is not a small number for a small account. For a $50,000 balance at 10.375%, you are looking at roughly $432 a month, over $5,000 a year. For $250,000 at 10.075%, closer to $2,100 a month. The rate looks like a percentage. The bill shows up as real dollars.

Whether that math is fine or terrible depends entirely on what the borrowed money is doing. If it is buying assets that outrun the interest rate (plus taxes on gains), it is arguably fine. If it is sitting in a stock you were “just about to sell,” it is bleeding you a little every day and you will not feel it until the tax form arrives. I have watched friends run both experiments; the second one is more common.

What a real margin bill looks like in dollars

Because rates in the abstract are impossible to feel, here is one worked example the way I would actually think about it. Say you have $50,000 in a brokerage account and you want to buy an extra $20,000 of an ETF you already own, using margin to fund the additional purchase. You do not sell anything. Fidelity extends the loan against your existing holdings, and you now carry a $20,000 debit balance.

At an 11.825% rate (because your balance is under $25,000), you owe about $2,365 a year in interest. That ETF needs to gain roughly 4.7% more than it would have anyway, just to break even against the interest. If the market is flat that year, you paid $2,365 for the privilege of being flat. If the ETF drops 10%, you lost the drop plus the interest, and if it drops far enough to trigger a margin call, you lose the drop plus the interest plus whatever Fidelity has to sell to bring you back into compliance. That is the shape of the bet.

None of that means margin is evil. It means the math has to work out ahead of time, in writing, before you enable it. My guide on how to invest money in 2026 without losing your mind is a better starting point for most people than any leverage product.

Fidelity’s margin requirements and the pattern-day-trader rule

You cannot just check a box and start borrowing at Fidelity. There are a few real gates.

The $2,000 floor. Federal rules require at least $2,000 of equity in an account before margin can be used. If your account is smaller than that, margin is not on the table until you fund it more.

The pattern-day-trader wall. If Fidelity’s system flags you as a pattern day trader (four or more day trades inside a rolling five-business-day window in a margin account), your equity minimum jumps to $25,000. Fall below that number and your margin trading gets locked down until you top it back up. This is a FINRA rule, not a Fidelity quirk, and it catches a lot of people who think they are being cute.

The 30% maintenance margin. Once you have a debit balance, Fidelity requires that your account equity stays at or above 30% of the total position value. If the market drops and your equity slides below that line, you get a maintenance call. Deposit cash, close positions, or Fidelity closes them for you. Fidelity is explicit in its own disclosures that it can liquidate your holdings without waiting for you to answer the phone.

How to enable (or disable) margin on Fidelity

The mechanics are almost embarrassingly quick, which is part of what makes it dangerous. Sign into Fidelity.com, click into Accounts & Trade, then Account Features. Scroll to the margin section and choose the account you want to enable. You will get a margin agreement to read (read it), a couple of suitability questions (answer them straight), and a submit button. Approval usually lands the same day or the next business day. Once you are approved, margin buying power is instantly available in that account.

Turning margin off is the same path in reverse. Accounts & Trade, Account Features, margin, and there is a request to remove the feature. You cannot disable margin while you have an outstanding debit balance, so you have to pay it off (or sell into it) first. Once your balance is zero, the removal is quick and does not affect the rest of your account. If you are not actively borrowing, turning margin off is a small, sane hygiene move that removes the temptation on a rough Wednesday.

Fidelity vs Schwab, Robinhood, and Interactive Brokers

Fidelity is not the cheapest place to borrow, and it does not really pretend to be. Here is the general shape of the market for a comparable balance under $25,000, using publicly posted rates in early 2026.

  • Interactive Brokers Pro: around 5.58%. The lowest big-broker rate, aimed at active traders and higher-net-worth clients. The platform itself is stiffer than Fidelity’s.
  • Robinhood Gold: a flat 6.75% at all tiers, but only for Gold subscribers (~$5 a month). Cheap on rate; the underlying platform pushes leverage in a way that will not be for everyone.
  • Charles Schwab: around 9.575% at the same tier, dropping to about 7.075% above $500K. Slightly cheaper than Fidelity across most tiers.
  • E*TRADE: around 10.70% under $25K, dropping to about 7.70% above $500K. Roughly Fidelity-adjacent.
  • Fidelity: around 11.825% under $25K, dropping to about 7.50% above $1M. The highest of this list at the small-account end, competitive at the very top.

The gap between Fidelity and Interactive Brokers on a $10,000 balance is roughly $620 a year. That is not trivial for what is otherwise the same trade. If you are borrowing frequently and your balance is small, the broker you pick is the largest single knob you can turn.

Why Fidelity margin rates are so high

Two plain reasons and one that Fidelity would rather you not think about.

Reason one: Fidelity funds its margin loans by borrowing short-term at the broker call rate, which itself tracks the federal funds rate, and then adds a few percentage points on top to cover risk management, regulatory capital, servicing, and profit. That spread is where their number comes from. When the Fed hikes, the base rate rises; when the Fed cuts, it falls. So the “why is it 11 percent” question is partly just “because short-term rates are high right now.”

Reason two is that Fidelity offers a full-service brokerage: research, live phone support, fractional shares, a mature app, cash management, checking, physical branches. That infrastructure is not free, and the margin rate is one of the levers they use to fund it. Robinhood can run a leaner rate because it runs a leaner product.

The uncomfortable reason is that most retail margin borrowers do not shop the rate. They enable margin on the account they already have, at the broker they already use, and eat whatever number they are handed. Fidelity’s tiered pricing reflects that reality. Small accounts pay near credit-card rates because they will; large accounts get chopped down because they will move to Interactive Brokers if they do not. If you have never called and asked, you are almost certainly in the “will pay” bucket.

When margin at Fidelity actually makes sense

I am openly skeptical of most retail use of margin, and I want to say that plainly before I hand you the short list of cases where it is defensible.

A truly short-term cash bridge. You are between paychecks or waiting on a settlement, you need liquidity for a few days, and selling positions would trigger a tax bill you do not want to eat. Borrowing $5,000 against a large portfolio for two weeks at 10-plus percent costs you a coffee’s worth of interest and beats selling. This works only if “two weeks” is real, not aspirational.

A concentrated buying opportunity with a clear exit. You want to add to a position on a real drawdown, you have a written thesis and a stop-loss, and you know exactly how you would unwind the borrow. This is the classic case that finance textbooks describe. It is also the one that goes sideways in real life most often, because “clear exit” almost always dissolves when the market keeps dropping.

A securities-backed alternative to a HELOC. For higher-net-worth readers with a large taxable brokerage, borrowing on margin can be cheaper and faster than a home equity line, especially for one-off expenses. Fidelity’s own securities-backed lending product (a variant of margin, marketed as portfolio-backed lending) sometimes offers even better rates than the standard margin schedule for balances over $250K or so. Ask specifically about SBLOC rates; they are negotiated, not published.

Even these cases assume you have already sorted the obvious pieces of your financial life. If you do not have a working emergency fund, if you carry credit card debt, or if you would need to sell to cover a margin call at the worst possible time, this is not your tool yet. My rundown on the differences between good debt and bad debt is a more useful frame for most readers than any leverage strategy.

When margin at Fidelity is a bad idea

The list is longer than the good-idea list on purpose.

Using margin as an ongoing cash-flow bridge, over and over, month after month. That is a signal your spending needs a look, not that you need cheaper credit. Using margin to buy non-appreciating anything (a car, a wedding, a vacation, a couch). You have taken on stock-market risk plus interest to fund a purchase that does not compound. Using margin to double down on a single position because you feel strongly about it. Feelings are not a thesis. Using margin without a plan for a margin call, which will happen exactly on the day the market has already ruined your mood.

Fidelity’s own marketing gently suggests margin as a way to fund home renovations or a boat. I am telling you plainly, as a guy who lives inside personal-finance content: that is a bad use of a leverage tool for almost every reader of this blog. Home equity lines exist. Personal loans exist. Cash exists. Do not put the ETF portfolio on the hook to redo a kitchen.

You can negotiate your Fidelity margin rate

Almost nobody knows this, and it makes a bigger difference than any other single move. Fidelity margin rates for large balances are negotiable. If you carry a debit balance above roughly $100,000 or hold a total account balance above around $500,000, you can call Fidelity, ask for a rate review, and often shave 50 to 150 basis points off your posted tier. Longtime clients with meaningful assets sometimes get much more.

The pitch is boring, on purpose. Something like: “I am carrying a debit balance in the low six figures. Interactive Brokers has me at [their published rate]. I would rather not move; can you review my margin rate?” You are not being aggressive, you are showing them the door and asking politely if they would like you to stay. Fidelity would rather keep the assets than win the interest fight.

If your balance is smaller, the negotiation lever is weaker, but sometimes still there, especially if you have been a customer for a decade and hold retirement, brokerage, and cash management with them. It costs a phone call and five minutes. This is the one line item in this whole piece I would push on hardest, because it is free money.

Where to double-check the numbers

Rates on this page were current when I wrote it, and probably out of date already by the time you are reading. Two authoritative places to spot-check: the official Fidelity commissions and margin rates page (their own current tiered schedule) and FINRA’s margin account explainer for the regulatory rules that apply across every US broker, not just Fidelity. If the numbers between this article and Fidelity’s own page ever disagree, trust Fidelity’s page.

A margin account at Fidelity is a legitimate tool that most retail investors will misuse, and a handful will use well. The rate schedule is not doing anything sneaky; it is expensive for small balances and reasonable for very large ones, exactly the way every big broker prices this. Enable it if you have a specific, written reason. Disable it if you do not. Call and negotiate if you carry a real balance. And if your gut is doing what mine did on a Tuesday afternoon a few years ago, closing the tab is a perfectly good answer.

📌 Save this one for the next time a group chat asks “should I turn on margin,” or drop a comment: what is the one leverage product (margin, HELOC, personal loan, 0% credit card) you have used, and would you use it again the same way?
