How do I calculate PnL on Bybit?

PnL = (exit - entry) x size for a long, or (entry - exit) x size for a short. ROE multiplies the price ROI by your leverage.

What is ROE on Bybit futures?

ROE is the return on the margin you posted, amplified by leverage. A 10% move at 10x leverage is roughly a 100% return on margin.

Do Bybit fees reduce my PnL?

Yes. Bybit charges about 0.055% taker per side plus funding every 8 hours, so net profit is a little below the raw price PnL. This tool shows gross PnL; subtract roughly two taker fees for a round trip.

How PnL and ROE work on Bybit

Bybit is one of the most popular derivatives exchanges, known for a fast matching engine and deep USDT-perpetual liquidity. Your raw profit on a Bybit trade is the price move times your position size: (Exit − Entry) × Size for a long, and the reverse for a short. Price ROI is the percentage the asset moved; ROE is your return on the margin you actually posted, which Bybit's leverage multiplies. Bybit built its reputation on execution speed and reliability during volatile candles, which is why scalpers and high-frequency traders gravitate to it. Its unified trading account lets spot, USDT-perpetual and inverse contracts share one margin pool, and its copy-trading marketplace is among the largest anywhere.

Worked example

A 0.5-coin long opened at $60,000 and closed at $66,000 at 10× leverage:

Profit (gross)+$3,000.00

Price ROI+10.00%

ROE (10×)+100.00%

Leverage cuts both ways - the same move down would be a 100% loss of margin. Plan your exit and check your Bybit liquidation price first.

ROE by leverage - same 10% move

ROE is just the price move multiplied by leverage. A single 10% winning move on Bybit returns, on the margin you posted:

Leverage	ROE on a +10% move	ROE on a −10% move
5×	+50%	−50%
10×	+100%	−100%
25×	+250%	−250%
50×	+500%	−500%
100×	+1,000%	−1,000%

The higher the leverage, the faster ROE compounds - and the smaller the move that liquidates you. That symmetry is why position sizing beats chasing leverage.

Fees & funding on Bybit

This tool shows gross PnL. On Bybit you also pay about 0.055% taker per side (so roughly 0.110% for a round trip at market), plus funding every 8 hours while the position is open. On a fast scalp the fees can outweigh a small edge, which is why makers (resting limit orders at 0.02%) keep more of their profit. Subtract those costs from the figure above for your true net result.

FAQ

How is ROE different from ROI on Bybit?

Price ROI is the raw % move. ROE multiplies it by your leverage - it is your return on posted margin. Fees and funding are not included in the gross figure.

Does Bybit show PnL automatically?

Bybit shows live PnL on open positions, but this tool lets you plan and compare scenarios before you trade - and see how leverage changes the ROE.

Is Bybit available in the US?

No - Global; not available to residents of the United States, the UK (retail) or a handful of sanctioned regions. US traders can use a domestic venue such as Kraken.
