Does this include funding payments?

No. Perpetual funding accrues per interval while a position is open and is independent of the price move, so it is calculated separately — use the funding rate calculator and add the two figures for a full holding-period result.

Why are long and short results not mirror images?

The price component is symmetric, but fees are not: they are charged in both directions regardless of which side you took. A short and a long on the same move therefore differ by twice the fee, which is why a trade that is marginally profitable one way can be a loss the other.

What fee rate should I enter?

Use your actual taker rate unless your orders reliably rest on the book, in which case use the maker rate. Perpetual taker fees commonly sit at 0.04%–0.06%; volume tiers and fee tokens lower them. Entering the optimistic maker rate for a strategy that crosses the spread is the most common way a backtest ends up unreachable in practice.

Profit, loss, and the fees between them

Leveraged profit and loss for long and short, with return on equity and round-trip fees separated out.

Updated 2026-08-18

A leveraged PnL calculator turns a price move into a cash result and a return on the margin actually committed. Notional is margin × leverage; profit is notional × the percentage price move, minus the fee charged on notional at both open and close. The distinction that matters is return on equity versus return on notional: at 10× leverage a 4.6% price move is a 46% account move, which is why the same trade looks modest on the chart and decisive in the balance.

Compare the fee line against the PnL line. At high leverage and short holding periods, fees frequently exceed the edge the strategy was designed to capture — a detail that disappears when a calculator reports gross profit only.

The formula

Notional  = Margin × Leverage
Move %    = (Exit − Entry) ÷ Entry × 100
Fees      = Notional × Fee % × 2      (open + close)

Long  PnL = Notional × Move %  − Fees
Short PnL = −Notional × Move % − Fees
ROE       = PnL ÷ Margin × 100

Funding payments are not included; see the funding rate calculator.

1 Enter the margin you are committing to the position — the money at risk, not the notional it controls.
2 Enter the leverage, then the entry and exit prices you want to evaluate.
3 Enter your per-side fee rate; use the taker rate if your orders cross the spread.
4 Read return on equity, then check the fee line against the PnL before concluding the trade is worth taking.

Return on equity is the number that decides survival

Leverage does not change the market, it changes the denominator. A position with $1,000 of margin at 10× controls $10,000 of notional, so every 1% of price movement is 10% of the money you actually put up. That is symmetric and it is the whole mechanism: the same multiple that makes a 4.6% rally into a 46% gain makes a 4.6% dip into a 46% loss, and at roughly 9.5% adverse movement the position is gone entirely. Reading PnL as a percentage of notional makes leveraged trading look calm; reading it against margin shows what is actually happening to the account.

Why fees scale with leverage

Trading fees are charged on notional, not on margin — which means raising leverage raises the fee bill in exact proportion while the capital at risk stays the same. At 10× with 0.05% per side, a round trip costs 1% of margin before the market has moved at all. Run that strategy twenty times a month and fees alone consume 20% of the account annually at a pace that no equity curve advertises. Any strategy operating on thin per-trade edges has to be evaluated after this line, not before it.
