Fees are charged on the entry and on the exit value. Funding is not included here; the funding calculator adds it.
PnL and ROE
PnL is the price move times the size: positive for a long when the price rises, for a short when it falls. ROE (return on equity) divides that by the margin, which is why it is the price move times the leverage. A 2 % move at 25× is a 50 % ROE, in either direction.
Fees
Exchanges charge the fee on the value traded, on the way in and on the way out. At high leverage the fee is a large share of the margin: 0.06 % twice at 50× is 6 % of the margin before the price has moved.
