Funding, fees and liquidation in practice

Funding is a periodic payment between longs and shorts that anchors the perpetual price to the underlying index. If you are long while the funding rate is positive, you typically pay; if short, you may receive. The funding calculator multiplies notional by rate and by the number of periods you expect to hold so overnight cost is visible before you enter.

Liquidation models vary, but higher leverage always pulls the estimated liquidation price closer to entry. Treat calculator output as a planning floor, leave buffer for fees and adverse mark spikes, and never assume the exchange will match a simplified formula tick-for-tick. Pair liquidation checks with P&L so reward and risk sit in the same mental model.

Venue fee helpers (including Delta Exchange–style estimates) show how basis points on notional affect net results on larger tickets. Compare maker versus taker assumptions if your strategy sometimes rests orders. When you are done planning, open the related guide on liquidation basics for a plain-language walkthrough.

India-based traders often fund accounts from INR and track P&L in rupees even when the contract is quoted in USDT. Convert carefully, include round-trip fees, and avoid ignoring the spread between deposit rate and the rate you assume in a calculator. Re-run numbers when volatility jumps — liquidation distance shrinks as leverage stays fixed and maintenance requirements rise on some venues.

Use these crypto calculators together with position sizing rules you already trust: max loss per trade, max leverage cap and a hard stop on holding through high funding. The tools accelerate arithmetic; risk discipline still comes from you. All Wikawe crypto calculators remain free, private and browser-based.
