Pick the tool by the decision you face
Start from the question you need answered, then use the matching calculator; each tool page carries its formula, a worked example and the scenarios computed with it.
Concepts, one page at a time
Each page explains one idea: the answer and its figures first, then an example you can recompute with the site's calculators, then the exchanges' own documentation.
Trading fees are more than one percentage
Maker, taker, spot, and derivatives rates can differ on the same exchange. A fair comparison holds the product, order type, notional, and account tier constant and includes both entry and exit.
Estimate the full cost of one tradeFunding is a variable holding cost
Funding may be positive or negative, and direction and settlement count affect the outcome. A past observation does not guarantee the next interval, so keep the timestamp and use a range.
Estimate funding over a holding periodLeverage magnifies exposure, not guaranteed return
Higher leverage generally leaves less room for an adverse move. Actual liquidation still depends on the exchange's maintenance-margin model, margin mode, and account state.
Check liquidation risk and assumptionsCompare cost and eligibility separately
A lower estimate is not automatically the right exchange for everyone. Data sources, regional eligibility, product access, transfer paths, and risk models need separate checks.
Compare exchanges under the same conditionsGlossary
These definitions follow the formulas the calculators use. Exchange rules can differ in detail or change, so the exchange's own documentation is authoritative before you trade.
- Perpetual futures
A futures contract with no expiry that can be traded long or short on margin with leverage. Funding settled at regular intervals keeps its price near spot, and a position can stay open as long as its margin holds.
- Notional value
The total value of a position at the current price: quantity × price. Fees and funding are charged on it rather than on the margin you post, so higher leverage does not make the same position any cheaper to hold.

- Leverage
The ratio of notional value to initial margin. At 10× a 1,000 USDT margin carries a 10,000 USDT position. It amplifies exposure and sensitivity to price, not the base on which fees are charged.

- Initial margin
The margin committed when a position opens: notional ÷ leverage. Under isolated margin it is roughly the most the trade can lose, and adding margin raises that ceiling with it.

- Maintenance margin rate
The minimum margin ratio needed to keep a position open. When the margin balance falls to it, plus the liquidation-fee reserve, liquidation triggers. Larger positions usually fall into higher tiers, which brings the liquidation level closer.

- Liquidation price
The price at which the margin balance exactly equals maintenance margin plus the fee reserve. DZPTO computes a simplified estimate, for isolated margin or a cross-margin account holding one position; the actual trigger follows the exchange's mark price, tiers and account state.

- Mark price
The reference price an exchange uses for unrealised P&L and liquidation. It is built on an index of several spot markets rather than the last trade, so a momentary spike on one market cannot trigger liquidation by itself. Switch the chart to mark price when judging how close liquidation is.

- Isolated and cross margin
Isolated margin ring-fences each position, capping its loss at its own margin. Cross margin lets all equity in the settlement asset support every position: a larger buffer, at the cost that one trade's loss can consume the margin behind the others.

- One-way and hedge mode
In one-way mode a contract holds one direction and an opposite order reduces the position first; in hedge mode a long and a short can be held together and are tracked separately. Switching requires closing every position and cancelling every order.
- USDT-margined and coin-margined
USDT-margined contracts use stablecoins such as USDT or USDC for margin and settlement, with profit in the stablecoin; coin-margined contracts use the coin itself, such as BTC, with a fixed dollar face value per contract and profit in the coin.
- Maker and taker
A maker posts an order that waits in the book and adds liquidity; a taker trades immediately against resting orders. Maker fees are usually lower, but a fill is not guaranteed, and chasing a missed fill can cost more than the fee saved.

- Funding rate
The mechanism that keeps a perpetual's price near the spot index. When positive, longs pay shorts; when negative, shorts pay longs. Each payment is position value × rate. It is a holding cost or income, not a directional signal.
Full explanationLive funding ratesPerpetual funding rate calculator
- Funding interval
Funding settles at fixed times — commonly every eight hours, three times a day, for major perpetuals such as BTC — and some contracts change their frequency. Only positions held at a settlement pay or receive, so days held cannot simply be multiplied by three.

- Slippage
The gap between the expected and the actual fill price. It grows with market orders, thin liquidity and fast markets, and a stop can fill well beyond its price for the same reason — which is why a risk budget should allow for it.

- Stop distance
The percentage distance from entry to the stop. It should come from where the strategy is proven wrong, and then determine the position size — choosing leverage first and fitting the stop inside the liquidation level gets the order backwards.

- Risk budget
The most a single trade may lose, usually a fixed share of account equity. Notional = risk budget ÷ (stop distance + round-trip fee rate + slippage rate), so fees and slippage use up part of the budget.

- Return on equity (ROE)
Return measured on initial margin: net profit or loss ÷ initial margin. The higher the leverage, the larger the ROE for the same price move — and the larger the loss.
- Average entry price
A position's average cost after several fills, weighted by quantity: total notional ÷ total quantity. It is the starting point for unrealized PnL, the liquidation price and the break-even price.
- Withdrawal and network fees
Taking assets off an exchange incurs the platform's withdrawal fee and the blockchain's network fee; some platforms combine them. The receiving platform must support the same network and the same token contract, or the deposit may be delayed or never credited automatically.

Frequently asked questions
Where should a first-time user start?
If you already know the trade conditions, start with the trading cost calculator. If leverage is involved, also review liquidation and funding tools.
Does DZPTO recommend which asset to buy?
No. DZPTO focuses on pre-trade cost, data, and risk checks. It does not provide price forecasts or buy and sell signals.
What if a definition here differs from the exchange's?
Go with the exchange. These definitions exist so the calculators and articles make sense; an exchange's tiers, liquidation fee or settlement frequency can differ in detail or change, and the signed-in documentation and order preview are final.
Should I learn leverage or funding first?
It depends how long you hold. For trades opened and closed the same day, start with leverage, liquidation and position size. For positions held several days, funding is often the main cost, so start with funding rates and settlement intervals.
