Convert the annual alternative return to days
Opportunity cost equals queued principal × alternative APR × queue days ÷ 365. The calculation uses simple interest, so the return grows linearly with the entered delay. Daily opportunity cost equals principal × alternative APR ÷ 365. Use a fixed queued value and one consistent quote currency. Days must be nonnegative; zero waiting days produce zero opportunity cost regardless of the alternative annual rate.
Compare a short and longer queue
Imagine a hypothetical queued value of $25,000 and a 5% alternative APR. A 14-day wait has a modeled opportunity cost of $25,000 × 0.05 × 14 ÷ 365, approximately $47.95. A 28-day wait doubles the amount to about $95.89. These values represent foregone modeled earnings, not a fee deducted by the staking protocol or a direct reduction in the queued token quantity.
Separate waiting time from investment risk
The alternative APR is an assumption, not a guaranteed available return. The model excludes earnings that might continue during a real queue, token price changes, exit fees, and reinvestment delays after withdrawal. If queued principal continues earning, the relevant comparison would require a net return difference rather than this zero-interest queue assumption. Use several plausible waiting periods to see sensitivity, while keeping clear that none establishes the future duration of a withdrawal request.
