Minecraft does not store a block break time anywhere. Every game tick the player adds a little progress to the block, and the block pops once that progress reaches 100%. The progress per tick comes from the tool mining speed, divided by the block hardness, then divided by 30 when the tool can harvest the block, or by 100 when it cannot. When the progress per tick is at least 1, the block breaks on the very next tick, the famous instamine. Otherwise the game rounds up to whole ticks, ceil(1 / progress), and 20 ticks make one second.
The shortcut most players remember is break time = hardness x 1.5 seconds with the right tool, or hardness x 5 seconds without it, then divided by the tool speed multiplier. The hand and any wrong-category tool use multiplier 1. Correct tiers go wood 2, stone 4, copper 5, iron 6, diamond 8, netherite 9, gold 12. Gold is the quickest tier by far, it simply breaks after a few blocks.
Because the answer is always rounded up to a full game tick, fast setups land on clean tick numbers, and any build that delivers 1 or more progress per tick becomes instant. The calculator prints the full damage-per-tick calculation for the block and tool you selected, so you can watch exactly when a block crosses the instant-breaking line.
Tool tier and speed multipliers
| Tool tier | Speed multiplier | Notes |
|---|---|---|
| Bare hand / wrong tool | 1 | No speed bonus, usually no drops |
| Wooden | 2 | Entry tier, breaks quickly |
| Stone | 4 | Easy step up from wood |
| Copper | 5 | New in 1.21, between stone and iron |
| Iron | 6 | Handles diamond and obsidian |
| Diamond | 8 | Fast and long-lasting |
| Netherite | 9 | Fastest tier that lasts |
| Gold | 12 | Quickest, but nearly useless durability |
Here is the catch: a wrong tool does more than remove the speed bonus. For blocks that require a specific tool, a wrong tool also switches to the slower divide-by-100 formula and the block drops nothing, so it breaks but you collect nothing. Breaking iron ore with a wooden pickaxe is the textbook example.
Efficiency, Haste, Fatigue and environment modifiers
Once the base speed is known, four modifiers come into play. Efficiency adds level squared plus 1 to the speed, Efficiency V adds 26, but only when the base speed is already above 1, so it does nothing on blocks your tool cannot mine quickly. Haste from a beacon or conduit multiplies the speed by 1 plus 0.2 per level, so Haste II is exactly a 40 percent boost. Combined, these two are how players instamine stone, ores and deepslate.
The penalties work the opposite way. Mining Fatigue from an elder guardian uses the hardcoded Java multipliers 0.3, 0.09, 0.0027 and 0.00081 for levels I through IV, so mining nearly freezes. Without the Aqua Affinity helmet enchantment, mining underwater divides the speed by 5, and being in the air, jumping, flying or swimming, divides it by 5 again. Stack both and you mine 25 times slower, which is why underwater builders put Aqua Affinity on their helmet and stand on a block.
Reference break times
| Block | Hardness | Hand (s) | Wood pickaxe (s) | Diamond pickaxe (s) |
|---|---|---|---|---|
| Dirt / Sand | 0.5 | 0.75 | 0.4 | 0.1 |
| Stone | 1.5 | 7.5 | 1.15 | 0.25 |
| Oak Log | 2 | 3 | 1.5 | 0.4 |
| Iron Ore | 3 | 15 | 15 | 0.6 |
| Deepslate | 3 | 15 | 2.25 | 0.6 |
| Obsidian | 50 | 250 | n/a | 9.4 |
These numbers assume the correct, unenchanted tool and no modifiers. Obsidian only breaks at a useful speed with a diamond or netherite pickaxe, so a wooden pickaxe shows n/a, it would take over four minutes and still drop nothing. Run any of these rows through the calculator with Efficiency, Haste and the environment penalties to see the exact result.
Frequently asked questions
How is mining speed calculated in Minecraft?
Minecraft computes a progress value per tick instead of a time. The tool speed is divided by the block hardness, then by 30 if the tool harvests it or by 100 if not. A value of 1 or higher means instant breaking. Otherwise the ticks needed are ceil(1 / progress), and seconds are ticks divided by 20.
What is the tool speed multiplier for each tier?
For a block inside your tool mining category the base speeds are wood 2, stone 4, iron 6, diamond 8, netherite 9 and gold 12. Gold is the fastest but least durable. The hand and wrong-category tools stay at speed 1.
Does Haste stack with Efficiency in Minecraft?
It does. Efficiency adds level squared plus 1 to the tool mining speed, and only when the base speed is above 1, so it never helps on blocks the tool cannot mine faster than a hand. Haste then multiplies the whole speed by 1 plus 0.2 per level. Running both is the standard way to instamine stone and ores.
Why is mining slower underwater in Minecraft?
When your eyes are in water and your helmet has no Aqua Affinity, mining speed is divided by 5. Being off the ground, jumping, flying or swimming, divides it by another 5. Both together make you 25 times slower, so Aqua Affinity and solid ground matter a lot underwater.
How many ticks does it take to break stone?
Stone has hardness 1.5. With a correct tool the formula gives 1.5 x 1.5 = 2.25 seconds, that is 45 ticks by hand, about 1.15 seconds or 23 ticks with a wooden pickaxe at speed 2, and about 0.25 seconds or 5 ticks with a diamond pickaxe at speed 8. Add Efficiency and Haste and stone becomes instant.
Why does a wooden pickaxe fail on obsidian?
Obsidian has hardness 50 and needs a diamond or netherite pickaxe to drop. A wooden pickaxe is the wrong tool, so the game applies the divide-by-100 formula and the block gives nothing. A diamond pickaxe takes about 9.4 seconds and a netherite pickaxe about 8.35 seconds.
