Why Bitget average fill price does not directly reveal the fee
An average execution price describes the prices and quantities that traded, while a fee describes what those executions cost. To reconcile a Bitget spot order, rebuild its gross traded value from the fills before comparing the separately recorded charges.
Start with the quantity weights
A price average is useful because it condenses a scattered execution into a readable figure. It is also easy to misuse. Giving every fill the same weight makes a small execution count as much as a large execution, so a simple average of the displayed prices can disagree with the actual order average without any fee error.
Use each executed quantity as its weight. Keep the asset units explicit: the traded asset supplies the quantity and the quoted asset supplies the price. The resulting gross value is a bridge between the detailed fills and the order summary. It is not automatically the amount of asset ultimately credited after charges.
Work through a hypothetical split order
Bitget's public standard spot base taker rate is 0.1%, checked 2026-10-10. That reference excludes any assumption that a discount applies to your account and does not establish regional or product eligibility. Check the actual schedule and execution classification when investigating a real order.
Suppose a hypothetical order buys 2 units at 100 USDT and another 3 units at 110 USDT. The fill values are 2 × 100 = 200 USDT and 3 × 110 = 330 USDT. Gross traded value is 200 + 330 = 530 USDT. Across 5 units, the weighted price is 530 ÷ 5 = 106 USDT per unit.
For a separate hypothetical fee illustration, assume every fill uses the quoted base taker rate and fees are paid in USDT without rounding differences. The total calculated charge is 530 × 0.001 = 0.53 USDT. The average execution price remains the weighted trading price under that definition; it does not become a fee-inclusive purchase price just because the fee is known.
Compare like fields before diagnosing a mismatch
Find out whether the order summary shows average execution price, a fee-adjusted figure or another measure. An app may shorten a label that an export spells out in detail. Preserve the definition alongside the value instead of deciding from appearance alone. A fee-inclusive figure and an execution-only figure answer different questions.
Then align the completed quantity. A partially filled order can have a valid average before the remaining quantity trades, and that average can change after later executions. A screenshot taken during execution may therefore disagree with the final history even when neither value was wrong when displayed.
Precision can conceal small differences
Displayed prices may be shorter than the underlying execution precision. Rebuilding value from rounded screen prices can produce a small residual against a detailed export. The same issue applies to rounded quantities and fee amounts. Where possible, calculate from the most detailed available execution record and round only when presenting your own subtotal.
Do not assume every residual is rounding. First confirm that all executions belong to the same order, that none were omitted, and that the fee comparison uses compatible units. If an adjustment changes a receipt later, retain the adjustment separately so that the original calculation remains understandable.
Fill reconciliation checklist
- [ ] Collect completed fill prices and quantities for the exact order.
- [ ] Multiply each price by its matching quantity before averaging.
- [ ] Divide gross traded value by the total executed quantity.
- [ ] Compare recorded fees using the applicable liquidity treatment and units.
- [ ] Explain precision or adjustment differences before accepting a residual.
Keep a copy of the final order state with the detailed receipts. That small habit makes later comparisons easier when a live order view has changed and the original screenshot no longer represents the completed execution.
Keep the average useful
Once the weighted price reconciles, use it for questions about execution quality, such as how the completed order compared with your intended limit. Use the fee receipts for questions about charges. Combining those records can support a broader cash-flow review, but keep the original measures visible so that another reader can reproduce your reasoning.
The Bitget venue page and rate comparison provide context for public schedules. The glossary explanation of slippage helps distinguish a worse execution price from an explicit charge; an unfavorable fill and a correctly charged fee can occur together.
