Jupiter quotes: expected output, minimum output and the actual exit
A route quote is a timestamped estimate for a size, not a promise that the last chart price is executable.

Quote the amount you mean
A swap quote describes a particular input, output mint, amount and route under observed market conditions. Increasing the amount can change the route and the average execution price. A chart’s most recent trade and a quote for selling a large position are therefore different measurements. For an exit analysis, the position size is essential context.
Two output numbers
In Jupiter’s documented ExactIn quote response, outAmount is the expected output after AMM and platform fees, while otherAmountThreshold represents the minimum acceptable output after the specified slippage tolerance. The estimate and the protection bound serve different purposes. Neither makes the quoted route permanently available. These field names belong to that API version and should not be assumed for every Jupiter interface. 1
Costs and state can change
Network fees, priority fees and tips need their own review. A token’s transfer behaviour may add further constraints. A fresh quote can differ because liquidity or routing changed, not because the chart visibly moved. If a transaction is rebuilt, the user should review the actual new message. A simulation provides information about a proposed execution under a particular state; settlement is established by the on-chain result. 2
A useful exit comparison
Compare several fractions of the same position using consistent denomination and observation time. Record expected net proceeds, the minimum bound, route and separately paid costs. Do not add independent quotes together as if all could execute against unchanged liquidity. A 25% sale can alter the state available for the next sale. This is a measurement method for understanding liquidity, not a recommendation to trade.
具体示例
A simplified quote expects 100 units out and applies a 1% slippage tolerance, giving a 99-unit minimum before any separately paid costs. The difference is a tolerance bound, not a guaranteed extra fee. Actual execution may produce an amount between these values or fail under changed conditions.
