Direct answer
For a 0.2 BTC long opened at 50,000 USDT at 10x (1,000 USDT of margin) with 0.05% taker fees, a net 20% return needs an exit at 51,050.53 USDT, a rise of about 2.10%; 50% needs 52,551.28 USDT (+5.10%). At 20x the same 20% needs only 50,550.28 USDT (+1.10%), but losses double in ROE terms too. For a short, the 20% target price is 48,950.52 USDT.
The result first
Assume a long of 0.2 BTC bought at 50,000 USDT — 10,000 USDT of notional — at 10x, so 1,000 USDT of initial margin, with taker fills at 0.05% on both trades. Enter 20% as the target return in the futures PnL calculator and it shows an exit at 51,050.53 USDT.
Netting 200 USDT — 20% of the margin — therefore needs the price to rise about 2.10%. With a 50% target the exit is 52,551.28 USDT, about +5.10%; a 100% target needs 55,052.53 USDT, about +10.11%.
At 20x the margin is only 500 USDT, so a 20% target means netting 100 USDT and an exit at 50,550.28 USDT, about +1.10%. The target looks easier to reach; the price is that the same pullback damages ROE twice as fast.
The formula behind it
Target net PnL = target return × initial margin. For a long, exit price = [entry × quantity × (1 + opening fee rate) + funding + target net PnL] ÷ [quantity × (1 − closing fee rate)].
In this example: (10,000 × 1.0005 + 0 + 200) ÷ (0.2 × 0.9995) = 10,205 ÷ 0.1999 = 51,050.53 USDT. Fees and funding sit inside the formula, so the target price already includes trading costs; nothing needs to be added on top.
For a short, exit price = [entry × quantity × (1 − opening fee rate) − funding − target net PnL] ÷ [quantity × (1 + closing fee rate)]. The same 10x short with a 20% target exits at 48,950.52 USDT, a fall of about 2.10%.
Take-profit prices by target and leverage
The same 0.2 BTC long with 0.05% taker fees: where to exit for each leverage and target return. The higher the leverage, the closer the same target — but an adverse move worsens ROE by the same multiple.
| Leverage | Target ROE | Take-profit (USDT) | Rise needed |
|---|---|---|---|
| 5× | 20% | 52,051.03 | 4.10% |
| 10× | 20% | 51,050.53 | 2.10% |
| 10× | 50% | 52,551.28 | 5.10% |
| 10× | 100% | 55,052.53 | 10.11% |
| 20× | 20% | 50,550.28 | 1.10% |
| 50× | 20% | 50,250.13 | 0.50% |
How costs move the target
For the same 10x, 20% target: with maker fills at 0.02% on both trades the take-profit drops to 51,020.20 USDT; held for seven days through 21 settlements at +0.01%, it must rise to 51,155.58 USDT to still net 20%.
The longer the hold, the more likely funding becomes the largest cost inside the target. That is what the calculator's funding rate and settlement fields are for.
The same formula gives the stop
Enter a negative target and the formula gives the price at which a chosen loss is reached. At 10x with a −30% target, the exit is 48,549.27 USDT, a fall of about 2.90%.
Use it to sanity-check a stop: if the −30% price is already close to the liquidation price, lower the leverage or the size rather than moving the stop further down.
A quick risk-reward check
Put the take-profit and the stop side by side: at 10x, a +20% take-profit needs a 2.10% rise and a −30% stop triggers on a 2.90% fall. With the stop further away than the target, the trade needs a win rate above roughly 60% to pay off.
The derived price is only a starting point. The decision belongs to the market: where support and resistance sit, how long you expect to hold, how much the instrument usually moves. The calculator gets the numbers right; the call is still yours.
Set the target against the market
Compare the required move with the typical range of the instrument over the time you expect to hold. If BTC's usual daily range is well below 5%, an intraday target of 50% ROE is asking for an unusual move.
Raising leverage brings the target closer only by buying more liquidation risk: at 20x, an adverse move of about 4.47% can approach liquidation, while the 20% target needs a 1.10% rise. Put the two distances side by side to see the trade's risk-reward.
Before placing the take-profit order
A take-profit usually fills as a limit order or a triggered market order, and that choice changes the closing fee: a maker fill is cheaper and lowers the target price slightly. Recalculate with the closing fee rate you will actually pay.
If the position will cross funding settlements, enter their number and rate; derive the stop the same way and confirm it sits well before the liquidation price. Finally, check the trigger price and order type in the exchange's order preview.
Official sources and calculation boundary
The target return uses initial margin as the denominator and fees follow executed notional, per OKX's futures PnL rules and Binance's fee documentation. The derived exit excludes slippage; a triggered order can fill away from its trigger price.

Frequently asked questions
Is a 20% target measured on margin or on notional?
On initial margin — the return on margin (ROE). Here the margin is 1,000 USDT, so 20% means netting 200 USDT.
Why isn't the short's target 49,000 USDT?
Because fees are deducted on both trades, the short must fall a little further to net 200 USDT; the exact price is 48,950.52 USDT.
Can the target return exceed 100%?
Yes. At 10x here, a 100% target needs 55,052.53 USDT, a rise of about 10.11%; the higher the target, the closer the required move gets to an unusual market.
Should a take-profit be a limit or a triggered market order?
A limit (maker) fill is cheaper and lowers the target slightly but may not fill; a triggered market order fills at the taker rate. The calculator's closing fee field lets you compare both.
