How to Calculate Best Concentrate Levels for Liquid Laundry Packets

The fastest way to calculate the best concentrate level for liquid laundry packets is to turn packet fill into an oz-per-load number, then map that dose to a 2X–6X concentration category, and validate performance across machines and water conditions. Measure the packet’s liquid volume (or mass and density), decide how many loads it’s meant to cover (usually one medium load), compute oz/load, and align labeling with industry ranges. From there, fine-tune for HE washers, water hardness, soil level, and load size, and confirm fast dissolution and low-suds rinse-out. Whirlpool’s concentration guidance defines the standard mapping ranges used by many auto-dispensers and labels, making this approach both consumer-clear and machine-compatible (see the Whirlpool concentration guidance). Cleaning Supply Review uses this mapping as a baseline in our detergent packet evaluations.
