Gamma fees depend on earned trading fees and the selected vault configuration
Updated
Gamma fees for LP vault management apply to earned trading fees under the vault's fee configuration. Comparing total costs also requires the gas for your transactions and any conversion needed to prepare the deposit. Use the same starting assets, contribution size and holding period across quotes. Keep price impact separate from explicit charges, and distinguish an immediate transaction estimate from a management deduction that depends on future fee earnings.
The amounts behind a comparable vault quote
A useful comparison starts with the amounts each charge applies to and what the quote already includes. A percentage of earned trading fees has a different basis from a percentage of deposited capital. Gas adds another cost, usually payable separately from the tokens entering the position. Combining these figures requires a common accounting unit and a consistent valuation time.
Record the proposed token quantities, the selected vault, the management fee basis and the transaction estimate. Include any conversion that precedes the deposit. A quote that ends with prepared tokens cannot directly compete with one that includes the completed vault deposit. Both estimates need the same endpoint before their totals mean the same thing.
Existing pool assets and assets that need conversion
Depositing compatible holdings
When existing balances fit the vault's accepted token proportions, a deposit can avoid a preparatory swap. The comparison then concerns the required permissions, deposit transaction and subsequent vault charges. Gamma's deposit ratio requirements determine the acceptable contribution. Equal token values alone do not establish that a proposed deposit fits those requirements.
Including a preparatory swap
Converting holdings introduces the swap's charges, execution price and any additional network cost. Two providers may quote different outputs for the same input because their routes use different liquidity. Compare the resulting quantities available for the vault deposit, not just the displayed swap fee. An attractive conversion price has limited value if its output does not meet the intended deposit requirements.
Does Gamma charge the management percentage on my whole deposit?
For LP vaults using the earned-fee model, the management percentage applies to earned trading fees rather than deposited principal. The applicable configuration belongs to the particular vault and implementation. A fee setting can change, so a historical percentage does not establish the deduction for another period. Zero earned trading fees produce no deduction under that percentage-of-earnings rule, although transaction costs and changes in asset value can still occur.
Transaction costs and earnings respond to different inputs
A transaction cost is not generally proportional to the amount deposited. Execution requirements and network conditions influence it, while the management deduction grows with the earned fees subject to that charge. Treat gas as a transaction estimate rather than a permanent fixed amount. Extending the holding period spreads entry costs across more time, but it does not establish how much trading-fee income the vault will earn.
Price impact changes the conversion result
Price impact is the change in the execution price caused by the trade itself. It affects the assets received from a preparatory conversion. The pool's swap fee is a separate charge. A route can therefore advertise a smaller fee yet return fewer usable tokens because its liquidity absorbs the trade less effectively.
Slippage describes the difference between the expected execution price and the price actually obtained. Slippage tolerance sets an acceptable execution boundary; it is not a fee that automatically leaves the wallet. Compare quoted outputs after their included charges. Adding those charges again would overstate costs, while treating the entire permitted slippage amount as a certain expense would confuse a limit with an outcome.
How do I calculate a comparable total?
Add the management deduction, explicit conversion charges and network costs once, using the same accounting unit. Keep any price-impact estimate separate unless you deliberately include it in a broader execution-cost measure.
Suppose you want to estimate costs before authorizing any transaction. Assume attributable gross trading fees of 83.72 accounting units over the chosen period and a management fraction of 0.172. Neither input represents an actual Gamma vault quote. Together, they produce a management deduction of 14.39984 units, or approximately 14.40 units.
Suppose the complete entry and exit gas estimate totals 5.82 units, while a necessary preparatory conversion charges 2.36 units. The estimated explicit cost is 14.39984 + 5.82 + 2.36 = 22.57984 units, approximately 22.58 units. This total excludes price impact and changes in the value of the deposited assets.
The choice is between proceeding with the proposed deposit and leaving the existing holdings unchanged. Before committing, the reader can compare another quote using those same holdings and the same intended deposit. The alternative must include all required operations. A smaller transaction estimate alone cannot establish a lower overall cost if it omits the conversion.
The estimate remains provisional while the reader has authorized no transaction. A changed gas estimate, conversion output or applicable management fraction invalidates the affected calculation. Future earned fees also remain an assumption. If the revised inputs no longer support the intended comparison, the reader can defer the deposit without incurring its transaction costs.
A quote and an executed transaction have different consequences
Comparing without changing the wallet
Reading a quote does not itself transfer tokens or create a vault position. This allows estimates to remain revisable before authorization. A displayed output reflects a particular state, however, so it does not reserve that execution price. The cost comparison should retain the quote's token quantities and time alongside its estimated charges.
Costs already incurred during preparation
An executed approval or preparatory swap changes the starting point for any later comparison. Approval can consume gas without creating the intended position. A completed swap changes the holdings available for deposit. Stopping afterward avoids subsequent transactions, but it does not reverse earlier costs. Keep those completed expenses in the overall record, separate from the additional cost of proceeding.
Are withdrawal costs included in a deposit quote?
A deposit quote does not establish the cost of a later withdrawal unless it explicitly includes an exit estimate. Gamma's LP vault withdrawal returns underlying pool assets for redeemed shares. The withdrawal transaction therefore has its own execution cost. Converting the returned assets into a different holding adds another operation when that conversion forms part of the intended exit.
Future network conditions and token balances remain unknown at entry. Label exit costs as estimates rather than presenting them as settled charges. Comparisons across providers should use equivalent exit outcomes: returning the underlying assets is a different endpoint from returning a chosen single asset. The latter requires accounting for the necessary conversion as well.
Net fee income and total position return
Net fee income subtracts the applicable management deduction from gross earned fees. Wallet transaction costs then reduce the amount retained economically. Where a balance or performance figure already includes a deduction, subtracting it again creates a false expense. Incentive rewards belong in a separate income entry so that temporary rewards do not obscure the cost structure.
Total position return also includes changes in the quantities and values of the underlying assets. Fee income alone cannot measure that outcome. Liquidity management changes the position's exposure as trading and range adjustments occur, so a lower management fraction does not establish better overall performance. The next decision is whether the quoted entry costs and the vault's ongoing fee basis fit the intended holding period and exit.
Gamma fees FAQs
Can a reverted Gamma deposit still cost gas?
A deposit transaction that executes onchain and reverts can still consume gas. The failed operation does not create the intended vault position, but the network charges for execution work. A wallet rejection before submission is different. Keep the failed transaction's actual network cost separate from any estimate for a later attempt.
Why can a raw vault fee field differ from the percentage shown in an interface?
A contract can encode its fee as a divisor rather than a percentage. Gamma's published Hypervisor implementation divides collected token fees by its fee parameter when calculating the recipient's share. The raw field therefore needs interpretation through the deployed implementation's arithmetic before comparison with a displayed percentage.
Should I divide gas costs by the deposit value when comparing different contribution sizes?
Dividing estimated gas by contribution value expresses that transaction expense as a share of the deposit. Use the same valuation unit for both amounts. This helps compare entry overhead across sizes, but the resulting percentage is not Gamma's management rate. It also does not include future withdrawals or charges absent from the estimate.
Does splitting one Gamma deposit into smaller deposits necessarily reduce costs?
Splitting a deposit does not necessarily reduce total costs because separate transactions can repeat execution expenses. If preparation includes swaps, changing their sizes also changes their execution conditions. Compare the combined required transactions and resulting token quantities. A smaller individual transaction estimate does not establish that the full contribution becomes cheaper.
When does an existing token approval change my cost estimate?
An existing approval can remove the need for a new approval transaction when its spender and remaining allowance satisfy the intended operation. That reduces the additional transactions required for that wallet. It does not change the vault's management configuration. Comparing quotes from different wallets can therefore produce different preparation costs for otherwise matching deposits.
Is a wallet's maximum gas estimate the amount I will necessarily pay?
A maximum gas estimate or spending ceiling is not necessarily the final network charge. Actual execution determines the charge within the transaction's applicable fee rules. Use the confirmed transaction receipt for an incurred cost and preserve the estimate for comparison. Do not replace a realized charge with the earlier maximum when calculating historical expenses.
