Understanding how to calculate the average entry price is essential for any trader navigating the world of cryptocurrency derivatives. Whether you're trading perpetual contracts or futures, knowing your average cost basis helps manage risk, set profit targets, and make informed decisions when adding to existing positions. This guide breaks down the calculation methods across different contract types—inverse contracts, USDT-margined perpetuals, and USDC-margined perpetuals—with clear formulas and real-world examples.
By mastering these calculations, traders gain better control over their portfolio performance and can optimize entry strategies in volatile markets.

Understanding Inverse Perpetual and Delivery Contracts
Inverse perpetual and delivery contracts are quoted in USD but settled in cryptocurrency, such as Bitcoin (BTC). This means profits, losses, and margin are all denominated in BTC rather than stablecoins or fiat. Because of this unique structure, the formula for calculating the average entry price differs from other contract types.
Formula for Inverse Contracts
To compute the average entry price:
Average Entry Price = Total Number of Contracts / Total Contract Value
Where:
Total Contract Value = (Quantity₁ / Price₁) + (Quantity₂ / Price₂) + ...
This method accounts for the inverse relationship between price and cryptocurrency value.
Example Calculation: BTCUSD Inverse Contract
Suppose a trader:
- Buys 50 contracts at $10,000
- Buys another 50 contracts at $15,000
First, calculate the total BTC value used:
(50 / 10,000) + (50 / 15,000) = 0.005 + 0.00333333 = 0.00833333 BTCTotal contracts = 100
Average entry price = 100 / 0.00833333 ≈ $12,000
Thus, the trader’s average entry point is $12,000. This weighted average reflects the higher exposure at the lower price level.

USDT-Margined Perpetual Contracts
USDT-margined perpetual contracts are quoted and settled in Tether (USDT), making them more intuitive for most traders. The profit and loss scale linearly with price movements, and margin requirements are stable due to the pegged nature of USDT.
Formula for USDT Perpetuals
Average Entry Price = Total Position Value / Total Number of Contracts
Where:
Total Position Value = (Quantity₁ × Price₁) + (Quantity₂ × Price₂) + ...
This is a straightforward arithmetic average weighted by position size.
Example Calculation: BTCUSDT Contract
A trader:
- Buys 1 BTC contract at $10,000
- Buys 2 BTC contracts at $13,000
Total position value:
(1 × 10,000) + (2 × 13,000) = 10,000 + 26,000 = 36,000 USDTTotal contracts = 3
Average entry price = 36,000 / 3 = $12,000
This result shows that larger positions have a greater influence on the average—here, the second trade pulls the average upward significantly.
USDC-Margined Perpetual Contracts
USDC-margined perpetual contracts function similarly to USDT versions but use USD Coin (USDC) as collateral. One key difference lies in how exchanges handle mark-to-market settlements during each funding period.
Unique Behavior: Settlement-Based Reset
In some platforms, the average entry price resets at the end of each settlement cycle based on the mark price at that time. This means past entries may be "locked in" and replaced with a new baseline.
However, during an active trading cycle, the average is calculated like USDT contracts:
Average Entry Price = Total Position Value / Total Quantity
Where:
Total Position Value = (Price₁ × Quantity₁) + (Price₂ × Quantity₂) + ...
Example Calculation: BTCUSDC Contract
Trader A:
- Holds 0.5 BTC long at $50,000 entry
- Adds 0.8 BTC at $51,000
Total position value:
(50,000 × 0.5) + (51,000 × 0.8) = 25,000 + 40,800 = 65,800 USDCTotal BTC quantity = 1.3 BTC
Average entry price = 65,800 / 1.3 ≈ $50,615.38
This updated average reflects a slightly higher cost basis due to the larger add-on at a higher price.
Note: Always check your exchange's specific rules—some platforms adjust average cost after funding events or liquidations.
Frequently Asked Questions (FAQ)
What is the purpose of calculating average entry price?
The average entry price helps traders determine their break-even point and assess profitability. It’s crucial for setting stop-loss and take-profit levels accurately.
Does averaging down always improve my position?
Not necessarily. While adding to a losing position at lower prices can reduce your average cost (averaging down), it also increases exposure. If the market continues moving against you, losses multiply. Always consider risk management before increasing position size.
Why do inverse contracts use a different formula?
Because inverse contracts are settled in crypto (e.g., BTC), each dollar gain or loss translates into varying amounts of cryptocurrency depending on price. The formula normalizes this non-linear relationship by measuring total coin value spent.
Is average entry price affected by leverage?
No. Leverage amplifies gains and losses but does not impact the calculation of average entry price. The formula depends only on trade size and execution price.
Can fees affect my average entry price?
Most platforms don’t include trading fees in the displayed average entry price. However, high-frequency traders should account for fees separately, as they impact net profitability over time.
How often should I recalculate my average entry?
Recalculate every time you open a new position or add to an existing one. Most advanced trading platforms update this automatically in real time.
Key Takeaways for Traders
Mastering the concept of average entry price empowers traders to build smarter strategies across various crypto derivatives:
- Use correct formulas based on contract type (inverse vs. linear).
- Understand how settlement mechanisms affect cost basis in USDC contracts.
- Avoid emotional trading—use data-driven averages instead of guesswork.
- Monitor changes after each trade to maintain accurate risk assessment.
Whether you're scaling into a bullish trend or managing a volatile portfolio, precise cost tracking is foundational to long-term success.
