How to Use the Genshin Impact Resin Planner
Resin regenerates automatically at 1 every 8 minutes, adding up to a maximum of 180 per day. Enter your current resin, max capacity, and how much you plan to spend each day, and this calculator tells you whether you'll actually run low — and if so, roughly how many days away that is.
If your daily spending plan stays at or under 180, natural regeneration alone keeps up, so your resin theoretically never runs out. But if farming events or weekly bosses push your usage above 180 for several days in a row, your stockpile shrinks a little each day until it eventually empties.
The calculator also shows how long a full refill takes. For example, refilling from 0 to a 200 cap takes about 26 hours 40 minutes — handy to know before you plan a farming session around it.
Frequently Asked Questions
One resin every 8 minutes, which adds up to a maximum of 180 per day (24 hours). If your daily spending stays under 180, your resin theoretically never runs out.
No. Once resin hits the max cap, natural regeneration stops and it stops accumulating. Beyond that, you can only add more through separate items like login rewards or event resin.
