HP / Mana Regeneration Time
Calculate how long it takes to regenerate health or mana to full from a flat regen per second and a percentage regen, free online.
About this calculator
Regeneration per second = flat regen + percent regen × max HP. Time to full = (max − current) ÷ regen per second. If regen is a percentage of your missing health, recovery slows down toward the end; this tool uses the standard linear model.
