99 Nights in the Forest Calculator

99 Nights in the Forest Calculator is a Roblox helper tool for the survival game 99 Nights in the Forest. It lets you plan crafting costs, wood gathering efficiency, diamond quest routes, and survival time all the way to Day 99 using formulas that match in-game mechanics.

You can quickly see how many logs, scraps, medallions and gems you need, how long wood farming will take, which quests to repeat for diamonds, and how much real time it takes to reach a target day with different day multipliers and Temporal Accelerometer setups.

Crafting cost planner

Select items from the crafting list, filter by bench level, and add them to your plan. The calculator will automatically sum up all logs, scraps, Cultist Medallions, Forest Gems, and extra days required so you can see the total cost of your build.

Wood gathering efficiency

Enter how many logs you need, choose your axe type, and set your hits per second. The tool estimates how many trees you must chop, total hits required, and the real-world time needed to gather enough wood.

Diamonds & quest planner

Input your current and target diamond counts. The calculator shows how many diamonds you still need and suggests a quest plan so you can efficiently reach your target without wasting time.

Survival time to Day 99

Set your target day, day multiplier, and whether you use the Temporal Accelerometer. The tool converts in-game days into real-time hours of day and night, total gems earned, and key milestones like Day 50 and Day 99.
