Minecraft Hopper Rate Calculator
Editions: Java + Bedrock (rate identical; one Java quirk in FAQ) · Verified: Java 26.3 / Bedrock 26.50 · 2026-09-16 · Updated 2026-09-16
Every hopper in the game moves exactly one item per 8 game ticks — 2.5 a second, 9,000 an hour — and that single number decides how long your storage system, furnace array, or farm output actually takes. Enter an item count and get the honest clock.
The worked example
Emptying a full double chest of 64-stack items — 3,456 items — through one hopper takes 3,456 ÷ 2.5 = 1,382.4 seconds: 23 minutes and 2.4 seconds of real time. A shulker box or single chest of the same stock (1,728 items) is half that, 11 minutes 31.2 seconds. Four parallel lines cut the double chest to 5 minutes 45.6 seconds, because throughput multiplies across independent lines even though a single line's speed is fixed by the 8-tick cooldown. Left running, one hopper moves 216,000 items a day; a million items is 111.1 hopper-hours.
Rates worth memorizing
| Window | Items through one hopper |
|---|---|
| 1 second | 2.5 |
| 1 minute | 150 |
| 1 hour | 9,000 |
| Double chest of 64-stacks | 23m 2.4s |
| Shulker box of 64-stacks | 11m 31.2s |
Rate verified against the Minecraft Wiki's hopper documentation (minecraft.wiki/w/Hopper); every number in this table is derived from the 8-tick cooldown stated there and asserted in our test suite. See the hopper throughput guide for what the rate means for farm design.
Questions builders actually ask
How fast does a Minecraft hopper move items?
One item every 8 game ticks: 2.5 items per second, 150 per minute, 9,000 per hour. The often-quoted 8,000 an hour is wrong — 2.5 multiplied by 3,600 seconds is 9,000, and the wiki states the figure directly.
How long does a hopper take to empty a double chest?
A double chest of ordinary 64-stack items holds 3,456 items, and 3,456 divided by 2.5 a second is 1,382.4 seconds — 23 minutes and 2.4 seconds. A single chest or shulker box of 64-stacks (1,728 items) takes 11 minutes 31.2 seconds.
Do more hoppers make item transfer faster?
A chain of hoppers does not: items still move one hopper step per cycle, so a longer line adds travel, not throughput. Parallel independent lines do multiply throughput — two lines carry 5 items a second, and the calculator splits the load with the busiest line deciding the finish time.
What does this calculator not model?
Two documented quirks: in Java, the first push into an empty hopper runs on a 7-tick cooldown instead of 8, and a stack falling through a vertical hopper pipe can move twice as fast because push and pull act in the same tick. Both make real systems slightly faster than the number shown, never slower.
