Before opening a futures position on the Binance Official Site or the Official Binance App, run a stress test that simulates how your account would respond to 5 typical adverse scenarios — this keeps you from being caught off guard when the market moves fast. If you just installed the app and aren't familiar with the setup yet, follow the Download Page first to get the basics configured. Below we'll walk through the testing method and the calculation details.
A stress test is essentially a rehearsal. Before you open a position, you set a few adverse price-swing scenarios and see how your account would actually perform under each one: how much your unrealized loss would be, what your margin ratio would drop to, and how much room you'd have left before liquidation.
Most beginners opening a futures position only think about "how much can I make if I'm right", without calculating "how much can I lose if I'm wrong". A stress test forces you to look at the downside first, which paradoxically makes you more rational.
| Test dimension | What it means | Importance |
|---|---|---|
| Unrealized loss | Unrealized loss in USDT when price moves N% against you | High |
| Margin ratio | Maintenance margin ratio after the loss | Very high |
| Liquidation price | How much room remains before liquidation | Very high |
| Funding cost | Cumulative funding paid over the holding period | Medium |
| Funding rate direction | Whether you're currently paying or receiving | Medium |
| Holding period | How long you plan to hold the position | Medium |
Binance's perpetual futures liquidation price formula (using USDT perpetual as an example):
Long liquidation price ≈ entry price × (1 - 1/leverage + maintenance margin rate) Short liquidation price ≈ entry price × (1 + 1/leverage - maintenance margin rate)
The maintenance margin rate depends on position size — for BTC/USDT perpetual it ranges from 0.4% to 2.5%. The larger the position, the higher the maintenance margin rate, and the closer the liquidation price sits to the entry price.
Example: BTC is currently at 70,000, and you open a 5x long with a 5,000 USDT margin (25,000 USDT notional value). The maintenance margin rate is roughly 0.4%. Liquidation price ≈ 70,000 × (1 - 1/5 + 0.004) = 70,000 × 0.804 ≈ 56,280 USDT.
In other words, you'd be liquidated once BTC drops to 56,280 (a 19.6% decline).
Using the example above — a 5x BTC long at 70,000 with 5,000 USDT margin — here are 5 adverse-move scenarios.
| Adverse move | BTC price | Unrealized loss (USDT) | Margin ratio | Distance to liquidation |
|---|---|---|---|---|
| 1% | 69,300 | -250 | 18.9% | 18.6% |
| 3% | 67,900 | -750 | 15.0% | 16.6% |
| 5% | 66,500 | -1,250 | 11.3% | 14.6% |
| 10% | 63,000 | -2,500 | 5.4% | 9.6% |
| 15% | 59,500 | -3,750 | 1.6% | 4.6% |
| 19.6% | 56,280 | -4,900 | ≈ 0% | Liquidated |
If BTC moves 10% against you, your margin ratio drops from an initial 20% to 5.4%. At that point you're already "hanging on" right at the edge of liquidation — another 5% move triggers it.
This table makes it visually obvious that with 5x leverage, a 10% adverse move is the danger zone. Beginners should treat "cut the position at a 5% adverse move" as a hard rule.
Binance's web-based futures trading page has a "Calculator" button in the top-right corner, with three functions: PNL calculator, target price calculator, and liquidation price calculator.
The liquidation price calculator takes entry price, leverage, and margin as inputs and gives you the liquidation price directly — no need to work out the formula yourself. You can also choose between cross and isolated margin (the liquidation price differs between the two).
The PNL calculator takes entry price, exit price, and position size, and gives you the profit/loss in USDT and the return percentage. It's a quick way to see the expected outcome of different take-profit and stop-loss levels.
| Calculator function | Input fields | Output |
|---|---|---|
| PNL | Entry price / exit price / quantity | PNL in USDT and % |
| Target price | Target PNL / quantity / direction | Required exit price |
| Liquidation price | Entry price / leverage / margin | Liquidation trigger price |
| Entry price | Current price / direction / leverage | Suggested entry point |
Third-party tools like CryptoLiquidationCalculator and Coinglass offer similar functions, and can even run stress tests across multiple coins at once.
The higher the leverage, the faster you get liquidated. Here's a reference table to quickly gauge the "safe adverse-move range" at different leverage levels.
| Leverage | Adverse move at liquidation | Margin ratio at 5% adverse move | Margin ratio at 10% adverse move |
|---|---|---|---|
| 1x | 99% | 95% | 90% |
| 2x | 49% | 80% | 60% |
| 3x | 32% | 70% | 40% |
| 5x | 19.6% | 50% | 0% (danger) |
| 10x | 9.6% | 0% (liquidated) | Already liquidated |
| 20x | 4.6% | Already liquidated | Already liquidated |
| 50x | 1.6% | Already liquidated | Already liquidated |
| 100x | 0.6% | Already liquidated | Already liquidated |
At 10x leverage, a 10% adverse move on BTC triggers liquidation — and that magnitude of move happens 10-15 times a year historically. At 20x leverage, a 5% adverse move triggers liquidation, which can happen 5-10 times a month. 50x and 100x are essentially "guaranteed to blow up" territory.
Beginners should keep leverage at 5x or below. Even experienced traders rarely run 20x or higher for extended periods.
If you're holding multiple futures positions at once (say, BTC long + ETH long + SOL short), you need to run a combined stress test.
Under cross margin, unrealized gains and losses across positions affect your shared margin ratio. If all three positions lose money in the same direction, your margin ratio drops quickly. If you have a hedge (one position losing while another gains), things stay relatively stable.
Example combined stress-test scenario: assume the market drops 10% broadly — your BTC long shows an unrealized loss of -1,000, your ETH long shows -800, and your SOL short shows an unrealized gain of +600. Net unrealized loss: -1,200. Total account margin is 5,000, so the current margin ratio ≈ (5,000 - 1,200) / total position value.
Binance's cross-margin leverage accounts display a real-time "combined margin ratio" so you can monitor overall risk.
Q: Is the liquidation price formula the same for cross margin and isolated margin on Binance?
The formula is the same, but "available margin" for cross margin is your entire account's net equity, while isolated margin only uses the margin allocated to that single position. That means cross margin's liquidation price is usually further away (safer), but the risk is that any one position getting liquidated affects the entire account.
Q: Does the maintenance margin rate change?
Yes. It rises in steps as your position size grows. For example, on BTC/USDT perpetual, positions worth 0-50,000 USDT have a 0.4% maintenance rate, 50,000-250,000 USDT sits at 0.5%, and positions above 1,000,000 USDT can reach 1% or more. The larger the position, the stricter the risk threshold.
Q: Should I factor in funding cost when stress testing?
If you're planning to hold for more than 24 hours, yes. For example, if you plan to hold for a week and BTC's funding rate annualizes to 12% (about 0.033% daily), that's roughly 0.23% in cumulative cost over the week. This cost further squeezes your profit and loss margin.
Q: How does Binance's auto-deleveraging mechanism work?
If a liquidated position can't be absorbed by market liquidity and the insurance fund, Binance triggers "Auto-Deleveraging" (ADL), forcibly closing part of the opposing positions held by the most profitable accounts, ranked by profitability. The odds of an average user getting hit by ADL are low, but it can happen in extreme market conditions.
Q: Does changing leverage change the liquidation price?
Yes. Adjusting leverage while a position is open (typically only applies to future positions, or adjusts the margin ratio) causes the liquidation price to be recalculated based on the new leverage. It's better to pick your leverage before opening a position and avoid adjusting it frequently while holding.
Q: Is there a "zero liquidation" futures strategy?
In theory, 1x leverage with 100% margin ratio comes close to zero-liquidation. But at 1x leverage, futures offer little advantage over spot, so you might as well trade spot directly. Other "zero liquidation" strategies out there are mostly marketing claims — real liquidation risk still exists.
