The five numbers, in the order they depend on each other
- Margin = position value ÷ leverage. Profit and loss come from position size: a 2,000 USDT position gains or loses 20 USDT per 1% move at any leverage. Leverage sets how much margin stands behind it.
- Trading fees = position value × fee rate, once to open and once to close. They are charged on the full position, not on the margin. OKX lists 0.0200% maker and 0.0500% taker for regular-tier perpetuals (fee table, read 2026-11-14).
- Breakeven = Entry × (1 + opening fee + funding paid) ÷ (1 − closing fee) for a long. The price has to move this far before closing makes money. Leverage does not change it.
- Funding fee = position value × funding rate at each settlement (OKX funding help, updated Oct 28, 2026). A positive rate means longs pay shorts. Only positions open at the settlement moment pay or receive. On an isolated position, funding you pay comes out of the margin.
- Liquidation price. OKX says a position may be reduced or liquidated when its maintenance margin ratio is at or below 100%, judged on the mark price (OKX liquidation help, updated 11 Aug 2026). Solved for price, an isolated long with no added margin is liquidated near Entry × (1 − 1/leverage) ÷ (1 − MMR − taker fee). Bybit publishes its own form in Liquidation Process (updated 2026-10-15), and MEXC in its Margin Calculation Guide.
The last two outputs put these together: your net result at a planned exit and at a stop, after fees and funding. If the stop lies beyond the liquidation price, the position would be liquidated before the stop is reached, and the calculator says so.
One trade at four leverage levels (worked example)
OKX rates · 2,000 USDT long at 150 · taker in and out · 3 funding payments at +0.01% · MMR 0.5%| Leverage | Margin (USDT) | Fees + funding (share of margin) | Breakeven | Liquidation |
|---|---|---|---|---|
| 5x | 400 | 2.60 (0.65%) | 150.20 | 120.66 (-19.56%) |
| 10x | 200 | 2.60 (1.30%) | 150.20 | 135.75 (-9.50%) |
| 20x | 100 | 2.60 (2.60%) | 150.20 | 143.29 (-4.47%) |
| 50x | 40 | 2.60 (6.50%) | 150.20 | 147.81 (-1.46%) |
Why your exchange may show different numbers
- Your fee tier. VIP levels, token-based discounts and contract-specific rates change the fee.
- Maintenance rate by tier. The rate rises with position size. OKX's published tiers for the BTC USDT perpetual start at 0.4% (up to 1,000 contracts, 100x max), then 0.5% (66.66x) and 0.75% (50x) (position tiers, read 2026-11-14).
- Funding is not fixed. The rate keeps changing until settlement, can be negative, and is charged on the mark-price value. This page uses your entry notional and one rate for every settlement.
- Cross margin. In cross mode the whole account balance backs the position; use the exchange's position panel.
- Mark price and slippage. Liquidation is judged on the mark price, and market orders can fill away from the price you saw.
Frequently asked questions
What does a crypto futures calculator work out?
For one trade it works out the margin needed, the trading fees, the breakeven exit price, the funding cost while holding, the liquidation price and the net profit or loss at a planned exit. This page does all of them from one set of inputs.
Which number should I calculate first?
Position size. Margin, fees, funding and the liquidation price all follow from it. Leverage only decides how much margin backs the position.
Does higher leverage increase my profit?
Not for the same position size. A 2,000 USDT position gains or loses the same amount per 1% move at 5x or 50x. Higher leverage means less margin, so the same result is a larger share of it and the liquidation price is closer.
How is funding included?
Funding per settlement is position value times the funding rate. Enter the rate and how many settlements you expect to hold through. A long pays when the rate is positive; a short receives.
Why does the liquidation price change after funding?
On an isolated position, funding you pay is taken from the position margin, which moves the liquidation price closer to entry. The calculator shows both the price at open and the price after the funding entered.
Does this work for cross margin?
No. In cross margin the liquidation price depends on the whole account. Use the estimated liquidation price on your exchange.
Is anything I type stored?
No. The calculation runs in your browser and nothing is transmitted.
