This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own [NEW] Hell's Kitchen 3 session. It will not click the shop.

Time Machine coin gap
Estimates how many Coins you still need to buy Time Machine once per Standard service. The listed price is 50 Coins, and the buff lasts for the current service only. Difficult mode disables power-ups, so this gap does not apply there. Defaults are examples, not your live balance.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
Change the 50 only if the in-game shop shows a different Time Machine price. Do not use this for Robux passes or for Difficult seasons.
