Satisfactory Splitter Calculator

SplittersBeltsLoad BalancingManifolds

A Mk.5 belt carries 780 items/min — but how do you split that evenly across a row of machines without starving the last one?

This Satisfactory splitter calculator does the math. Enter your input belt rate and how many outputs you need, and it returns the per-output rate, how many splitters to chain, and the belt tier each line requires — so your manifolds and load balancers run perfectly even, with no bottlenecks.

Splitting 780/min across 4 outputs gives 195/min each. Each output fits on a Mk.3 (270/min) belt.

Manifold vs. load balancer

A manifold runs one belt past every machine with a splitter at each, which is simple and self-balances once buffers fill. A load balanceruses a tree of splitters and mergers to give every output the exact same rate immediately — better for even, perpetual splits, especially when the per-output rate isn't a whole number. The calculator tells you the per-output rate and splitter count for either approach.

Pair this with the production calculator to know each machine's input rate, and the miner calculator to size the belt coming off your nodes.
