Run-end coins are round((floor(seconds/5)+floor(kills ×0.25)+bosses ×80+pickup coins)×coin multiplier). For 600 s,400 kills,3 bosses and 120 pickup coins, the subtotal is 580; with only Amulet Coin’s ×1.5 bonus it becomes 870. Gacha refunds are separate 15/30/60/120/300 coins by rarity, and ticket rewards are not multiplied.

Count all rift coin drops before run settlement

An ordinary rift legend also executes the Boss reward branch: ten pickups of 5 coins and one held item. Its legendary branch adds ten pickups of 8 coins and three ordinary tickets. Total dropped coins are therefore 130 across 20 pickups, plus the item, healing, magnet, Bond and 50% chance of one ×10 ticket. Collecting all those coins adds 130 to pickup coins in the settlement formula. The ordinary rift legend also counts as a Boss defeat, adding the separate 80-coin Boss term; that term is not another dropped pickup. Judgment legends give XP only and do not use these reward branches.

Multipliers and a usable spending plan

The permanent Coins upgrade adds 8% per level, up to 8. With 4 levels its factor is 1.32; combined with Amulet Coin,1.32×1.5=1.98 and this same subtotal pays 1,148 coins after rounding. That multiplier applies to run settlement, not every mission or gacha refund. Use 250 coins for the HP 0→3 example on your chosen partner, then compare the remaining budget against its own attack or recovery prices.
