Fees & Funding Calculator (Simple)
How to Use the Fees & Funding Calculator
This calculator estimates the total cost of holding a crypto futures position — combining trading fees and funding payments over your holding period.
Input Fields
- Pair (COIN/USDT)
- The trading pair, e.g. BTCUSDT. Start typing to search across 500+ coins on the selected exchange.
- Exchange
- Choose one of the supported exchanges: Binance, Bybit, OKX, KuCoin, Bitget, Gate.io, MEXC, HTX. The Fetch all button pulls the current fees and funding rate for the selected pair.
- Side: Long / Short
-
Determines the direction of the funding payment.
Long — you pay funding when the rate is positive, receive when negative.
Short — the opposite: you receive when positive, pay when negative. - Entry Price
- The price at which you open the position. Used to calculate the break-even shift.
- Position Size (USDT)
-
The total notional value of the position.
Example: 10× leverage on $1,000 margin = $10,000 position size. - Open Fee / Close Fee (taker, %)
-
Trading fees charged when opening and closing the position.
Typical values: 0.04%–0.06% taker for major exchanges. - Funding Rate (%)
-
The periodic funding rate. Perpetual futures use this mechanism to keep the contract price
close to the spot price.
Positive rate — longs pay shorts.
Negative rate — shorts pay longs.
Typical range: −0.01% to +0.03% per 8h interval. - Holding Period (Hours / Days)
- How long you plan to hold the position. Toggle between hours and days. The calculator multiplies funding per interval by the number of intervals in this period.
Output Fields
- Total Fees
-
Combined open + close trading fees.
Formula: Size × (feeOpen + feeClose).
Example: $10,000 × (0.05% + 0.05%) = $10. - Funding / Interval
-
Funding payment per single interval (every 8h, 4h, or 1h).
Formula: Size × Funding Rate.
Example: $10,000 × 0.01% = $1.00 per 8h. - Total Funding
-
Cumulative funding over the entire holding period.
Formula: Funding/Interval × Number of Intervals.
Example: $1.00 × 3 intervals (24h / 8h) = $3.00. - Total Cost
-
Fees + funding combined. The true price of holding the position.
Example: $10 fees + $3 funding = $13 total. - Cost % of Position
-
Total cost as a percentage of position size.
Example: $13 / $10,000 = 0.13%.
Advanced Mode
Switch to Advanced to unlock extra inputs and detailed results:
- Leverage
- Used to calculate margin and cost as percentage of margin (not just position size).
- Funding Interval (8h / 4h / 1h)
- Most exchanges use 8h intervals. Some (like Bybit for certain pairs) use 4h or 1h. This changes how many funding payments occur per day.
- Open Fee / Close Fee (detailed)
- Shown separately in the results so you can see the cost of each leg.
- Funding / Day
- Daily funding cost. With 8h intervals = 3 payments/day; 4h = 6; 1h = 24.
- Margin Used
-
Collateral locked by the exchange.
Formula: Size / Leverage. - Cost % of Margin
- Total cost as percentage of your margin (collateral), not the full position. This is usually much higher than Cost % of Position.
- Break-even Shift
-
How much the price must move in your favor just to cover the total cost.
Formula: Total Cost / Qty.
Example: $13 cost / 0.1538 BTC = $84.5 price shift needed.
Quick Example
You hold a Long BTC position: size = $10,000,
entry = $65,000, fees = 0.05% taker, funding = +0.01% / 8h,
holding for 24 hours.
Trading fees = $10 • Funding = $3 (3 intervals) • Total cost = $13
Cost = 0.13% of position • Break-even shift ≈ $84.5
The price needs to move at least $84.5 in your favor just to break even after costs.
Frequently Asked Questions
-
What are trading fees in crypto futures?
Exchanges charge a fee every time you open or close a position. There are two types: Maker fees (for limit orders that add liquidity) are lower, typically 0.01–0.02%. Taker fees (for market orders that remove liquidity) are higher, typically 0.04–0.06%. Fees are calculated on the full notional value, not just your margin. A $10,000 position with a 0.05% taker fee costs $5 per side ($10 round-trip). -
What is the funding rate in perpetual futures?
The funding rate is a periodic payment between long and short holders that keeps the perpetual contract price aligned with spot. When the rate is positive, longs pay shorts (market is bullish). When negative, shorts pay longs. Funding is calculated as: Position Size × Funding Rate. Typical rates range from −0.01% to +0.03% per interval. -
How often is funding paid?
Most exchanges (Binance, Bybit, OKX, Bitget) settle funding every 8 hours (3 times per day). Some exchanges use 4-hour or even 1-hour intervals for certain pairs. You only pay or receive funding if you hold a position at the exact settlement time. Closing before settlement avoids that interval's funding payment. -
Why are funding costs important for holding crypto futures positions?
Funding costs can add up significantly over time. A seemingly small 0.01% per 8 hours equals 0.03% per day or roughly 0.9% per month. On a $50,000 position, that is $450/month in funding alone. For swing traders and position holders, funding can eat into or even exceed your trading profits. Always factor in the total holding cost before entering a position. -
What is the break-even shift?
The break-even shift is how much the price must move in your favor just to cover all costs (fees + funding). For example, if your total cost is $13 on a 0.1538 BTC position, the price needs to move $84.50 in your direction before you start profiting. This metric helps you evaluate whether a trade is worth the holding cost, especially for longer time frames.
