Assumptions, in plain English

This is a scenario calculator, not historical performance or a yield forecast. Starting price and fee APR are editable assumptions. Ranges snap to the selected fee tier’s tick spacing in a normalized asset/USD pool. Live pool decimals and token order may produce different ticks.

Price follows a straight path to the selected exit. Fees use constant APR on the starting capital, scaled by the fraction of that path spent in range. There is no automatic fee boost for narrower ranges. Gas, swaps, slippage, rebalancing and compounding are excluded. Each holding comparison uses that range’s own initial token mix.
